在 Python 中向 PDF 添加椭圆形状

添加 Ellipse 对象

Aspose.PDF for Python via .NET 允许您添加 Ellipse 使用 the 将形状添加到 PDF 页面 Graph 类。您可以绘制椭圆轮廓、设置填充颜色，并在椭圆对象内部放置文本。

import aspose.pdf as ap
import aspose.pdf.drawing as drawing

def add_ellipse(outfile: str):
    document = ap.Document()
    page = document.pages.add()
    graph = drawing.Graph(400, 400)
    graph.border = ap.BorderInfo(ap.BorderSide.ALL, ap.Color.green)

    ellipse1 = drawing.Ellipse(150, 100, 120, 60)
    ellipse1.graph_info.color = ap.Color.green_yellow
    ellipse1.text = ap.text.TextFragment("Ellipse")
    graph.shapes.add(ellipse1)

    ellipse2 = drawing.Ellipse(50, 50, 18, 300)
    ellipse2.graph_info.color = ap.Color.dark_red
    graph.shapes.add(ellipse2)

    page.paragraphs.add(graph)
    document.save(outfile)

创建填充椭圆对象

以下代码片段展示了如何添加 a。 Ellipse 被颜色填充的对象。

import aspose.pdf as ap
import aspose.pdf.drawing as drawing

def create_ellipse_filled(outfile: str):
    document = ap.Document()
    page = document.pages.add()
    graph = drawing.Graph(400, 400)
    graph.border = ap.BorderInfo(ap.BorderSide.ALL, ap.Color.green)

    ellipse1 = drawing.Ellipse(100, 100, 120, 180)
    ellipse1.graph_info.fill_color = ap.Color.green_yellow
    graph.shapes.add(ellipse1)

    ellipse2 = drawing.Ellipse(200, 150, 180, 120)
    ellipse2.graph_info.fill_color = ap.Color.dark_red
    graph.shapes.add(ellipse2)

    page.paragraphs.add(graph)
    document.save(outfile)

在椭圆内添加文本

Aspose.PDF for Python via .NET 还允许您在形状对象内放置文本。下面的示例向椭圆形状添加文本。

import aspose.pdf as ap
import aspose.pdf.drawing as drawing

def add_text_inside_ellipse(outfile: str):
    document = ap.Document()
    page = document.pages.add()
    graph = drawing.Graph(400, 400)
    graph.border = ap.BorderInfo(ap.BorderSide.ALL, ap.Color.green)

    text_fragment = ap.text.TextFragment("Ellipse")
    text_fragment.text_state.font = ap.text.FontRepository.find_font("Helvetica")
    text_fragment.text_state.font_size = 24

    ellipse1 = ap.drawing.Ellipse(100, 100, 120, 180)
    ellipse1.graph_info.fill_color = ap.Color.green_yellow
    ellipse1.text = text_fragment
    graph.shapes.add(ellipse1)

    ellipse2 = ap.drawing.Ellipse(200, 150, 180, 120)
    ellipse2.graph_info.fill_color = ap.Color.dark_red
    ellipse2.text = text_fragment
    graph.shapes.add(ellipse2)

    page.paragraphs.add(graph)
    document.save(outfile)
