# 管理 Python via Java 的 PowerPoint 文字段落

> 了解如何使用 Aspose.Slides for Python via Java 建立與格式化段落、文字片段、項目符號、編號清單、縮排、HTML 內容以及段落影像。

Source: https://docs.aspose.com/slides/zh-hant/python-java/manage-paragraph/


## **概览**

Aspose.Slides for Python via Java 將文字表示為文字框、段落和文字片段的層級結構：

* [TextFrame](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/textframe/) 表示形狀中的文字容器，並提供對其段落集合的存取。
* [Paragraph](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/) 表示文字框中的一個段落，並提供對其文字片段及段落層級格式設定的存取。
* [Portion](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/portion/) 表示段落內的一段文字。每個文字片段都可以擁有自己的文字內容和字元層級的格式設定。

因此，段落可以透過使用多個文字片段來包含不同字型、顏色、大小和其他格式的文字。

## **建立與格式化段落**

### **建立包含多個文字片段的段落**

以下步驟建立一個文字框，內含三個段落，每個段落都有三個文字片段：

1. 建立 [Presentation](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/presentation/) 類別的實例。
2. 透過索引存取相應的投影片。
3. 在投影片上新增一個矩形的 [AutoShape](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/autoshape/)。
4. 取得形狀的 [TextFrame](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/textframe/)。
5. 使用預設段落，並向文字框中再加入兩個 [Paragraph](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/) 物件。
6. 為每個段落新增足夠的 [Portion](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/portion/) 物件，使其包含三個文字片段。預設段落已包含一個空的文字片段。
7. 設定每個文字片段的文字內容。
8. 透過 [Portion.getPortionFormat](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/portion/#getPortionFormat) 套用字元層級的格式設定。
9. 儲存已修改的簡報。

此 Python 範例實作上述步驟：

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import FillType, NullableBool, Paragraph, Portion, Presentation, SaveFormat, ShapeType
from java.awt import Color

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 150, 300, 150)
    text_frame = shape.getTextFrame()
    first_paragraph = text_frame.getParagraphs().get_Item(0)
    first_paragraph.getPortions().add(Portion())
    first_paragraph.getPortions().add(Portion())
    second_paragraph = Paragraph()
    second_paragraph.getPortions().add(Portion())
    second_paragraph.getPortions().add(Portion())
    second_paragraph.getPortions().add(Portion())
    text_frame.getParagraphs().add(second_paragraph)
    third_paragraph = Paragraph()
    third_paragraph.getPortions().add(Portion())
    third_paragraph.getPortions().add(Portion())
    third_paragraph.getPortions().add(Portion())
    text_frame.getParagraphs().add(third_paragraph)
    paragraph_count = text_frame.getParagraphs().getCount()
    for paragraph_index in range(paragraph_count):
        paragraph = text_frame.getParagraphs().get_Item(paragraph_index)
        portion_count = paragraph.getPortions().getCount()
        for portion_index in range(portion_count):
            portion = paragraph.getPortions().get_Item(portion_index)
            portion.setText(f"Portion {paragraph_index + 1}.{portion_index + 1}")
            if portion_index == 0:
                portion.getPortionFormat().getFillFormat().setFillType(FillType.Solid)
                portion.getPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.RED)
                portion.getPortionFormat().setFontBold(NullableBool.True_)
                portion.getPortionFormat().setFontHeight(15)
            elif portion_index == 1:
                portion.getPortionFormat().getFillFormat().setFillType(FillType.Solid)
                portion.getPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLUE)
                portion.getPortionFormat().setFontItalic(NullableBool.True_)
                portion.getPortionFormat().setFontHeight(18)
    presentation.save("paragraphs_with_portions.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **建立項目符號與編號清單**

### **建立項目符號或編號清單**

項目符號與編號可以讓相關項目更易於瀏覽。於 Aspose.Slides 中，清單設定是透過 [BulletFormat](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/bulletformat/) 定義的。

1. 建立 [Presentation](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/presentation/) 類別的實例。
2. 透過索引存取相應的投影片。
3. 在選取的投影片上新增一個 [AutoShape](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/autoshape/)。
4. 取得形狀的 [TextFrame](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/textframe/)。
5. 從文字框中移除預設段落。
6. 為符號項目符號建立一個 [Paragraph](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/)。
7. 將 [BulletFormat.setType](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/bulletformat/#setType) 設為 [BulletType.Symbol](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/bullettype/#Symbol)，並指定項目符號字元。
8. 設定段落文字、縮排、項目符號顏色和項目符號高度。
9. 將段落加入文字框。
10. 建立第二個段落，並將 [BulletFormat.setType](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/bulletformat/#setType) 設為 [BulletType.Numbered](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/bullettype/#Numbered)。
11. 配置編號項目符號樣式，並將段落加入文字框。
12. 儲存簡報。

此 Python 範例建立符號項目符號與編號項目符號：

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import BulletType, ColorType, NullableBool, NumberedBulletStyle, Paragraph, Presentation, SaveFormat, ShapeType
from java.awt import Color

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 200, 200, 400, 200)
    text_frame = shape.getTextFrame()
    text_frame.getParagraphs().clear()
    symbol_paragraph = Paragraph()
    symbol_paragraph.setText("Welcome to Aspose.Slides")
    symbol_paragraph.getParagraphFormat().getBullet().setType(BulletType.Symbol)
    symbol_paragraph.getParagraphFormat().getBullet().setChar("•")
    symbol_paragraph.getParagraphFormat().setIndent(25)
    symbol_paragraph.getParagraphFormat().getBullet().getColor().setColorType(ColorType.RGB)
    symbol_paragraph.getParagraphFormat().getBullet().getColor().setColor(Color.BLACK)
    symbol_paragraph.getParagraphFormat().getBullet().setBulletHardColor(NullableBool.True_)
    symbol_paragraph.getParagraphFormat().getBullet().setHeight(100)
    text_frame.getParagraphs().add(symbol_paragraph)
    numbered_paragraph = Paragraph()
    numbered_paragraph.setText("This is a numbered item")
    numbered_paragraph.getParagraphFormat().getBullet().setType(BulletType.Numbered)
    numbered_paragraph.getParagraphFormat().getBullet().setNumberedBulletStyle(NumberedBulletStyle.BulletCircleNumWDBlackPlain)
    numbered_paragraph.getParagraphFormat().setIndent(25)
    numbered_paragraph.getParagraphFormat().getBullet().getColor().setColorType(ColorType.RGB)
    numbered_paragraph.getParagraphFormat().getBullet().getColor().setColor(Color.BLACK)
    numbered_paragraph.getParagraphFormat().getBullet().setBulletHardColor(NullableBool.True_)
    numbered_paragraph.getParagraphFormat().getBullet().setHeight(100)
    text_frame.getParagraphs().add(numbered_paragraph)
    presentation.save("bulleted_and_numbered_list.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

### **使用圖片項目符號**

圖片項目符號讓您使用自訂圖像取代符號或數字。

1. 建立 [Presentation](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/presentation/) 類別的實例。
2. 透過索引存取相應的投影片。
3. 新增一個 [AutoShape](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/autoshape/) 並取得其 [TextFrame](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/textframe/)。
4. 從文字框中移除預設段落。
5. 載入項目符號圖像，並以 [PPImage](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/ppimage/) 方式加入簡報的圖像集合。
6. 建立一個 [Paragraph](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/) 並設定其文字。
7. 將 [BulletFormat.setType](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/bulletformat/#setType) 設為 [BulletType.Picture](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/bullettype/#Picture)。
8. 透過 [BulletFormat.getPicture](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/bulletformat/#getPicture) 指定圖像，並設定項目符號高度。
9. 將段落加入文字框。
10. 儲存已修改的簡報。

此 Python 範例建立圖片項目符號：

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import BulletType, Images, Paragraph, Presentation, SaveFormat, ShapeType

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    bullet_image = Images.fromFile("bullets.png")
    try:
        presentation_image = presentation.getImages().addImage(bullet_image)
    finally:
        bullet_image.dispose()
    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 200, 200, 400, 200)
    text_frame = shape.getTextFrame()
    text_frame.getParagraphs().clear()
    paragraph = Paragraph()
    paragraph.setText("Welcome to Aspose.Slides")
    paragraph.getParagraphFormat().getBullet().setType(BulletType.Picture)
    paragraph.getParagraphFormat().getBullet().getPicture().setImage(presentation_image)
    paragraph.getParagraphFormat().getBullet().setHeight(100)
    text_frame.getParagraphs().add(paragraph)
    presentation.save("picture_bullet.pptx", SaveFormat.Pptx)
    presentation.save("picture_bullet.ppt", SaveFormat.Ppt)
finally:
    presentation.dispose()
```

### **建立多層級清單**

將 [ParagraphFormat.setDepth](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setDepth) 設為不同的深度，以將段落放置於清單的不同層級。最高層的深度為 `0`。

1. 建立一個 [Presentation](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/presentation/) 並存取投影片。
2. 新增一個 [AutoShape](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/autoshape/) 並清除其文字框中的預設段落。
3. 建立四個段落並配置其項目符號符號。
4. 為它們的 [ParagraphFormat.setDepth](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setDepth) 設定值 `0`、`1`、`2`、`3`。
5. 將段落加入文字框，並儲存簡報。

此 Python 範例建立四層級的項目符號清單：

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import BulletType, FillType, Paragraph, Presentation, SaveFormat, ShapeType
from java.awt import Color

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 200, 200, 400, 200)
    text_frame = shape.getTextFrame()
    text_frame.getParagraphs().clear()
    first_paragraph = Paragraph()
    first_paragraph.setText("Content")
    first_paragraph.getParagraphFormat().getBullet().setType(BulletType.Symbol)
    first_paragraph.getParagraphFormat().getBullet().setChar("•")
    first_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().setFillType(FillType.Solid)
    first_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK)
    first_paragraph.getParagraphFormat().setDepth(0)
    second_paragraph = Paragraph()
    second_paragraph.setText("Second level")
    second_paragraph.getParagraphFormat().getBullet().setType(BulletType.Symbol)
    second_paragraph.getParagraphFormat().getBullet().setChar('-')
    second_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().setFillType(FillType.Solid)
    second_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK)
    second_paragraph.getParagraphFormat().setDepth(1)
    third_paragraph = Paragraph()
    third_paragraph.setText("Third level")
    third_paragraph.getParagraphFormat().getBullet().setType(BulletType.Symbol)
    third_paragraph.getParagraphFormat().getBullet().setChar("•")
    third_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().setFillType(FillType.Solid)
    third_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK)
    third_paragraph.getParagraphFormat().setDepth(2)
    fourth_paragraph = Paragraph()
    fourth_paragraph.setText("Fourth level")
    fourth_paragraph.getParagraphFormat().getBullet().setType(BulletType.Symbol)
    fourth_paragraph.getParagraphFormat().getBullet().setChar('-')
    fourth_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().setFillType(FillType.Solid)
    fourth_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK)
    fourth_paragraph.getParagraphFormat().setDepth(3)
    text_frame.getParagraphs().add(first_paragraph)
    text_frame.getParagraphs().add(second_paragraph)
    text_frame.getParagraphs().add(third_paragraph)
    text_frame.getParagraphs().add(fourth_paragraph)
    presentation.save("multilevel_list.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

### **自訂編號清單起始值**

使用 [BulletFormat.setNumberedBulletStartWith](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/bulletformat/#setNumberedBulletStartWith) 來設定編號段落的起始數字。

1. 建立一個 [Presentation](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/presentation/) 並在投影片上新增一個 [AutoShape](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/autoshape/)。
2. 清除形狀文字框中的預設段落。
3. 建立三個編號段落。
4. 為相應段落將 [BulletFormat.setNumberedBulletStartWith](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/bulletformat/#setNumberedBulletStartWith) 設為 `2`、`3`、`7`。
5. 將段落加入文字框，並儲存簡報。

此 Python 範例為每個段落指定自訂的起始編號：

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import BulletType, Paragraph, Presentation, SaveFormat, ShapeType

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 200, 200, 400, 200)
    text_frame = shape.getTextFrame()
    text_frame.getParagraphs().clear()
    first_paragraph = Paragraph()
    first_paragraph.setText("Start at 2")
    first_paragraph.getParagraphFormat().getBullet().setType(BulletType.Numbered)
    first_paragraph.getParagraphFormat().getBullet().setNumberedBulletStartWith(2)
    text_frame.getParagraphs().add(first_paragraph)
    second_paragraph = Paragraph()
    second_paragraph.setText("Start at 3")
    second_paragraph.getParagraphFormat().getBullet().setType(BulletType.Numbered)
    second_paragraph.getParagraphFormat().getBullet().setNumberedBulletStartWith(3)
    text_frame.getParagraphs().add(second_paragraph)
    third_paragraph = Paragraph()
    third_paragraph.setText("Start at 7")
    third_paragraph.getParagraphFormat().getBullet().setType(BulletType.Numbered)
    third_paragraph.getParagraphFormat().getBullet().setNumberedBulletStartWith(7)
    text_frame.getParagraphs().add(third_paragraph)
    presentation.save("custom_numbered_list.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **控制段落版面與結尾屬性**

### **設定首行縮排**

使用 [ParagraphFormat.setIndent](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setIndent) 來控制段落的首行縮排。此方法僅移動第一行相對於段落左邊距的距離。正值會將首行向右移，而其餘行則保持與段落正文對齊。

當需要移動整個段落時，請使用 [ParagraphFormat.setMarginLeft](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setMarginLeft)；當只需要移動首行時，請使用 [ParagraphFormat.setIndent](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setIndent)。

以下範例建立多個段落，並套用不同的 [ParagraphFormat.setIndent](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setIndent) 值，以示範首行縮排如何影響段落版面。

1. 建立 [Presentation](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/presentation/) 類別的實例。
2. 取得目標投影片。
3. 在投影片上新增一個矩形的 [AutoShape](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/autoshape/)。
4. 取得形狀的 [TextFrame](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/textframe/) 並移除預設段落。
5. 建立多個段落，為它們設定不同的 [ParagraphFormat.setIndent](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setIndent) 值。
6. 將段落加入文字框。
7. 儲存已修改的簡報。

此程式碼示範如何設定段落縮排：

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import FillType, Paragraph, Presentation, SaveFormat, ShapeType, TextAutofitType
from java.awt import Color

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 420, 220)
    shape.getFillFormat().setFillType(FillType.NoFill)
    shape.getLineFormat().getFillFormat().setFillType(FillType.Solid)
    shape.getLineFormat().getFillFormat().getSolidFillColor().setColor(Color.GRAY)
    text_frame = shape.getTextFrame()
    text_frame.getTextFrameFormat().setAutofitType(TextAutofitType.Shape)
    text_frame.getParagraphs().clear()
    first_paragraph = Paragraph()
    first_paragraph.setText("No first-line indent. Wrapped lines start at the same position as the first line.")
    first_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().setFillType(FillType.Solid)
    first_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK)
    first_paragraph.getParagraphFormat().setMarginLeft(20.0)
    first_paragraph.getParagraphFormat().setIndent(0.0)
    second_paragraph = Paragraph()
    second_paragraph.setText("First-line indent of 20 points. The first line moves to the right, while wrapped lines remain aligned to the paragraph body.")
    second_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().setFillType(FillType.Solid)
    second_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK)
    second_paragraph.getParagraphFormat().setMarginLeft(20.0)
    second_paragraph.getParagraphFormat().setIndent(20.0)
    third_paragraph = Paragraph()
    third_paragraph.setText("First-line indent of 40 points. This paragraph shows a larger first-line offset to make the effect easier to see.")
    third_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().setFillType(FillType.Solid)
    third_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK)
    third_paragraph.getParagraphFormat().setMarginLeft(20.0)
    third_paragraph.getParagraphFormat().setIndent(40.0)
    text_frame.getParagraphs().add(first_paragraph)
    text_frame.getParagraphs().add(second_paragraph)
    text_frame.getParagraphs().add(third_paragraph)
    presentation.save("paragraph_indent.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

結果：

![段落的首行縮排](first_line_indent.png)

### **設定懸掛縮排**

懸掛縮排是指段落的第一行位於其餘行左側的版面配置。於 Aspose.Slides 中，可透過 [ParagraphFormat.setIndent](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setIndent) 並傳入負值，使第一行相對於段落正文向左移動。

實作上，[ParagraphFormat.setMarginLeft](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setMarginLeft) 定義段落正文的左側位置，而 [ParagraphFormat.setIndent](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setIndent) 定義第一行相對於該左側位置的偏移。若要建立懸掛縮排，請對 [ParagraphFormat.setMarginLeft](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setMarginLeft) 傳入正值，並對 [ParagraphFormat.setIndent](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setIndent) 傳入負值。

此格式在參考文獻、書目、詞彙表等需要讓換行後的文字對齊於段落正文而非首行第一個字元的情況下特別有用。

1. 建立 [Presentation](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/presentation/) 類別的實例。
2. 取得目標投影片。
3. 在投影片上新增一個矩形的 [AutoShape](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/autoshape/)。
4. 取得形狀的 [TextFrame](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/textframe/) 並移除預設段落。
5. 為每個段落傳入正值至 [ParagraphFormat.setMarginLeft](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setMarginLeft)。
6. 傳入負值至 [ParagraphFormat.setIndent](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setIndent) 以建立懸掛縮排效果。
7. 將段落加入文字框。
8. 儲存已修改的簡報。

此程式碼示範如何為段落設定懸掛縮排：

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import FillType, Paragraph, Presentation, SaveFormat, ShapeType, TextAutofitType
from java.awt import Color

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 420, 220)
    shape.getFillFormat().setFillType(FillType.NoFill)
    shape.getLineFormat().getFillFormat().setFillType(FillType.Solid)
    shape.getLineFormat().getFillFormat().getSolidFillColor().setColor(Color.GRAY)
    text_frame = shape.getTextFrame()
    text_frame.getTextFrameFormat().setAutofitType(TextAutofitType.Shape)
    text_frame.getParagraphs().clear()
    first_paragraph = Paragraph()
    first_paragraph.setText("A hanging indent is created by combining a positive left margin with a negative indent. The first line starts to the left, while wrapped lines align with the paragraph body.")
    first_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().setFillType(FillType.Solid)
    first_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK)
    first_paragraph.getParagraphFormat().setMarginLeft(40.0)
    first_paragraph.getParagraphFormat().setIndent(-20.0)
    second_paragraph = Paragraph()
    second_paragraph.setText("This second example uses a deeper hanging indent so the difference between the first line and the wrapped lines is easier to compare.")
    second_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().setFillType(FillType.Solid)
    second_paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK)
    second_paragraph.getParagraphFormat().setMarginLeft(60.0)
    second_paragraph.getParagraphFormat().setIndent(-30.0)
    text_frame.getParagraphs().add(first_paragraph)
    text_frame.getParagraphs().add(second_paragraph)
    presentation.save("hanging_indent.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

結果：

### **設定段落結尾執行屬性**

[Paragraph.setEndParagraphPortionFormat](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/#setEndParagraphPortionFormat) 控制段落結尾標記的格式設定。以下範例為第二個段落的結尾標記指定字型大小與拉丁字型：

1. 載入一個 [Presentation](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/presentation/) 並取得投影片。
2. 新增一個 [AutoShape](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/autoshape/) 並清除其預設段落。
3. 建立兩個段落，並向它們加入文字片段。
4. 為第二個段落的結尾標記建立一個 [PortionFormat](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/portionformat/)。
5. 設定 [BasePortionFormat.setFontHeight](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/baseportionformat/#setFontHeight) 與 [BasePortionFormat.setLatinFont](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/baseportionformat/#setLatinFont)。
6. 以 [Paragraph.setEndParagraphPortionFormat](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/#setEndParagraphPortionFormat) 套用格式，並儲存簡報。

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import FontData, Paragraph, Portion, PortionFormat, Presentation, SaveFormat, ShapeType

presentation = Presentation("Test.pptx")
try:
    slide = presentation.getSlides().get_Item(0)
    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 10, 10, 200, 250)
    text_frame = shape.getTextFrame()
    text_frame.getParagraphs().clear()
    first_paragraph = Paragraph()
    first_portion = Portion("Sample text")
    first_paragraph.getPortions().add(first_portion)
    second_paragraph = Paragraph()
    second_portion = Portion("Sample text 2")
    second_paragraph.getPortions().add(second_portion)
    end_paragraph_format = PortionFormat()
    end_paragraph_format.setFontHeight(48)
    latin_font = FontData("Times New Roman")
    end_paragraph_format.setLatinFont(latin_font)
    second_paragraph.setEndParagraphPortionFormat(end_paragraph_format)
    text_frame.getParagraphs().add(first_paragraph)
    text_frame.getParagraphs().add(second_paragraph)
    presentation.save("end_paragraph_format.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **匯入與匯出段落內容**

### **將 HTML 文字匯入段落**

使用 [ParagraphCollection.addFromHtml](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphcollection/#addFromHtml) 可將 HTML 標記轉換為文字框中的段落與文字片段。

1. 建立 [Presentation](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/presentation/) 類別的實例。
2. 取得投影片並新增一個 [AutoShape](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/autoshape/)。
3. 取得形狀的 [TextFrame](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/textframe/) 並清除預設段落。
4. 讀取來源 HTML 檔案。
5. 將 HTML 字串傳入 [ParagraphCollection.addFromHtml](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphcollection/#addFromHtml)。
6. 儲存已修改的簡報。

此 Python 範例將 HTML 匯入文字框：

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import FillType, Presentation, SaveFormat, ShapeType
from pathlib import Path

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    shape_width = presentation.getSlideSize().getSize().getWidth() - 20
    shape_height = presentation.getSlideSize().getSize().getHeight() - 20
    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 10, 10, shape_width, shape_height)
    shape.getFillFormat().setFillType(FillType.NoFill)
    shape.getTextFrame().getParagraphs().clear()
    try:
        html = Path("file.html").read_text(encoding="utf-8")
        shape.getTextFrame().getParagraphs().addFromHtml(html)
        presentation.save("html_text.pptx", SaveFormat.Pptx)
    except OSError as exception:
        print("The HTML file could not be read: " + str(exception))
finally:
    presentation.dispose()
```

### **將段落文字匯出為 HTML**

使用 [ParagraphCollection.exportToHtml](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphcollection/#exportToHtml) 可將選取的段落範圍匯出為 HTML。

1. 建立 [Presentation](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/presentation/) 類別的實例並載入目標簡報。
2. 取得投影片，並找出包含文字的 [AutoShape](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/autoshape/)。
3. 取得形狀的 [TextFrame](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/textframe/)。
4. 呼叫 [ParagraphCollection.exportToHtml](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphcollection/#exportToHtml)，並提供起始段落索引與要匯出的段落數量。
5. 將回傳的 HTML 字串寫入檔案。

此 Python 範例匯出第一個文字形狀中的所有段落：

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import AutoShape, Presentation
from pathlib import Path

presentation = Presentation("ExportingHTMLText.pptx")
try:
    shape = presentation.getSlides().get_Item(0).getShapes().get_Item(0)
    if isinstance(shape, AutoShape):
        text_shape = shape
        text_frame = text_shape.getTextFrame()
        if text_frame is not None:
            paragraphs = text_frame.getParagraphs()
            html = paragraphs.exportToHtml(0, paragraphs.getCount(), None)
            try:
                Path("paragraphs.html").write_text(str(html), encoding="utf-8")
            except OSError as exception:
                print("The HTML file could not be written: " + str(exception))
        else:
            print("The first shape does not contain a text frame.")
    else:
        print("The first shape is not a text shape.")
finally:
    presentation.dispose()
```

### **將段落渲染為影像**

[Paragraph.getImage](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/) 可直接渲染單一段落並回傳影像物件。使用其 `save` 方法將結果儲存至檔案或串流。您不必渲染整個形狀或手動裁切位圖。

如果段落在父集合中找不到、沒有有效的渲染範圍，或無法渲染，[Paragraph.getImage](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/) 會回傳 `None`。在儲存之前請先檢查結果，使用完畢後記得釋放影像。

#### **在預設比例渲染段落**

假設我們有一個名為 sample.pptx 的簡報檔，內有一張投影片，第一個形狀是一個包含三個段落的文字方塊。

![包含三個段落的文字方塊](paragraph_to_image_input.png)

以下範例在預設比例下渲染第二個段落，並以 PNG 格式儲存回傳的影像。`finally` 區塊確保正確釋放影像。

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import AutoShape, ImageFormat, Presentation

presentation = Presentation("sample.pptx")
try:
    shape = presentation.getSlides().get_Item(0).getShapes().get_Item(0)
    if isinstance(shape, AutoShape):
        text_shape = shape
        text_frame = text_shape.getTextFrame()
        if text_frame is not None and text_frame.getParagraphs().getCount() > 1:
            paragraph = text_frame.getParagraphs().get_Item(1)
            paragraph_image = paragraph.getImage()
            if paragraph_image is not None:
                try:
                    paragraph_image.save("paragraph.png", ImageFormat.Png)
                finally:
                    paragraph_image.dispose()
            else:
                print("The paragraph could not be rendered.")
        else:
            print("The expected paragraph was not found.")
    else:
        print("The first shape is not a text shape.")
finally:
    presentation.dispose()
```

結果：

![段落影像](paragraph_to_image_output.png)

#### **在表格儲存格中以縮放渲染段落**

使用接受 `scale_x` 與 `scale_y` 參數的 [Paragraph.getImage](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/) 重載，以設定水平與垂直的縮放比例。以下範例建立一個表格，於第一個儲存格中以兩倍寬度與高度渲染段落，並將結果存為 PNG 影像。

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ImageFormat, Presentation

scale_x = 2.0
scale_y = 2.0
presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    table = slide.getShapes().addTable(50, 50, [300.0], [80.0])
    paragraph = table.get_Item(0, 0).getTextFrame().getParagraphs().get_Item(0)
    paragraph.setText("Text in a table cell")
    paragraph_image = paragraph.getImage(scale_x, scale_y)
    if paragraph_image is not None:
        try:
            paragraph_image.save("table_paragraph.png", ImageFormat.Png)
        finally:
            paragraph_image.dispose()
    else:
        print("The paragraph could not be rendered.")
finally:
    presentation.dispose()
```

縮放因子 `1` 代表該軸保留預設像素大小。例如，兩個因子皆為 `2` 時，產生的影像寬高大約為預設尺寸的兩倍，像素數量則為四倍。較大的因子通常提供較銳利的文字，以利放大或高解析度輸出，但也會增加記憶體使用量與檔案大小。低於 `1` 的因子會產生較小且細節較少的影像。使用相同的水平與垂直因子可保留段落的長寬比例；不同的因子則會分別拉伸輸出。

在需要包含形狀填色、邊框或其他視覺上下文時，仍可使用 [Shape.getImage](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/shape/#getImage) 來渲染整個形狀。若僅需段落影像，請使用 [Paragraph.getImage](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/)。

## **常見問題**

**我可以完全停用文字框內的自動換行嗎？**

可以。將 [TextFrameFormat.setWrapText](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/textframeformat/#setWrapText) 設為 `False` 即可停用換行，使文字不在文字框邊緣斷行。

**如何取得特定段落在投影片上的實際邊界？**

使用 [Paragraph.getRect](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraph/#getRect) 可取得段落的外接矩形。若要取得單一文字片段的邊界，請使用 [Portion.getRect](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/portion/#getRect)。

**段落對齊方式（左、右、置中或兩端對齊）在哪裡設定？**

[ParagraphFormat.setAlignment](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/paragraphformat/#setAlignment) 為段落層級的設定，會套用於整個段落，與各文字片段的格式無關。

**我可以為段落中的部分文字設定校對語言嗎？**

可以。對個別文字片段使用 [BasePortionFormat.setLanguageId](https://reference.aspose.com/slides/zh-hant/python-java/aspose.slides/baseportionformat/#setLanguageId) 即可讓同一段落包含多種語言的文字。
