创建 PS 文档

Aspose.Page for Java 提供了两个构造函数来创建 PsDocument 类。以下代码片段用于创建一个单页 PS 文档:

 1//Create output stream for PostScript document
 2FileOutputStream outPsStream = new FileOutputStream(dataDir + "document.ps");
 3//Create save options with A4 size
 4PsSaveOptions options = new PsSaveOptions();
 5
 6//If you want to aassign page size other than A4, set page size in options
 7options.setPageSize(PageConstants.getSize(PageConstants.SIZE_A4, PageConstants.ORIENTATION_PORTRAIT));
 8//If you want to aassign page margins other than empty, set page margins in options
 9options.setMargins(PageConstants.getMargins(PageConstants.MARGINS_ZERO));
10//If you plan to use fonts that located in non system folders, set additional fonts folders in options
11options.setAdditionalFontsFolders(new String[] { FONTS_FOLDER });
12
13//Set variable that indicates if resulting PostScript document will be multipaged
14boolean multiPaged = false;
15
16// Create new multipaged PS Document with one page opened
17PsDocument document = new PsDocument(outPsStream, options, multiPaged);
18
19//Close current page
20document.closePage();
21//Save the document
22document.save();

如果 PS 文档计划为多页格式,请将 multiPaged 变量设置为 true

另一个构造函数允许创建具有指定页数的 PsDocument 对象:

 1//Create save options with A4 size
 2PsSaveOptions options = new PsSaveOptions();
 3//Create output stream for PostScript document
 4FileOutputStream outPsStream = new FileOutputStream(dataDir + "CreateDocument_outPS.ps");
 5
 6// Create new multipaged PS Document with 2 pages. These two pages are not created. It must be added by addPage() method.
 7PsDocument document = new PsDocument(outPsStream, options, 2);
 8
 9//Close current page
10document.closePage();
11//Save the document
12document.save();

请参阅在 .NET 中使用 PS 文档。

让我们看一下 PsSaveOptions 类,它封装了有助于创建正确 PostScript 文档的可用选项。

1options.setPageSize(PageConstants.getSize(PageConstants.SIZE_International, PageConstants.ORIENTATION_PORTRAIT));

默认页面尺寸为“纵向”方向的“A4”。

1options.setMargins(PageConstants.getMargins(PageConstants.MARGINS_SMALL)); // 20 points for each margin

默认边距为“零”(0, 0, 0, 0)。

1options.setBackgroundColor(new Color(211, 8, 48));

或:

1options.setBackgroundColor(Color.YELLOW);

默认值为“null”,表示无背景。

1options.setEmbedFontsAs(FontsConstants.EMBED_FONTS_TYPE3);

默认值为“TrueType”。
