Criar Documento PS

O Aspose.Page para Java oferece dois construtores para criar a classe PsDocument. O seguinte excerto de código cria um documento PS de 1 página:

 1// Create new multipaged PS document from scratch.
 2
 3String outputFileName = "document_out.ps";
 4
 5//Create save options
 6PsSaveOptions options = new PsSaveOptions();
 7//If you want to aassign page size other than A4, set page size in options
 8options.setPageSize(PageConstants.getSize(PageConstants.SIZE_A4, PageConstants.ORIENTATION_PORTRAIT));
 9//If you want to aassign page margins other empty, set page margins in options
10options.setMargins(PageConstants.getMargins(PageConstants.MARGINS_ZERO));
11//If you plan to use fonts that located in non system folders, set additional fonts folders in options
12options.setAdditionalFontsFolders(new String[] { getDataDir() });
13
14//Set variable that indicates if resulting PostScript document will be multipaged
15boolean multiPaged = false;
16
17// Create new multipaged PS Document with one page opened
18PsDocument document = new PsDocument(getOutputDir() + outputFileName, options, multiPaged);
19
20//Close current page
21document.closePage();
22//Save the document
23document.save();

Se o documento PS tiver várias páginas, defina a variável multiPaged para true.

Outro construtor permite criar um objeto PsDocument com um número definido de páginas:

 1// Create new PS document with defined number of pages.
 2
 3String outputFileName = "document_out.ps";
 4
 5//Create save options
 6PsSaveOptions options = new PsSaveOptions();
 7//If you want to aassign page size other than A4, set page size in options
 8options.setPageSize(PageConstants.getSize(PageConstants.SIZE_A4, PageConstants.ORIENTATION_PORTRAIT));
 9//If you want to aassign page margins other empty, set page margins in options
10options.setMargins(PageConstants.getMargins(PageConstants.MARGINS_ZERO));
11//If you plan to use fonts that located in non system folders, set additional fonts folders in options
12options.setAdditionalFontsFolders(new String[] { getDataDir() });
13
14// Create new multipaged PS Document with 2 pages. These two pages are not created. It must be added by OpenPage() method.
15PsDocument document = new PsDocument(getOutputDir() + outputFileName, options, 2);
16
17//Add the first page
18document.openPage(null);
19//Close current page
20document.closePage();
21//Save the document
22document.save();

Veja como trabalhar com documentos PS em .NET.

Vamos analisar a classe PsSaveOptions que encapsula possíveis opções que ajudam a criar o documento PostScript correcto.

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

O tamanho de página predefinido é “A4” na orientação “Retrato”.

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

As margens por defeito são “ZERO” (0, 0, 0, 0).

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

ou:

1options.setBackgroundColor(Color.YELLOW);

O valor predefinido é “null”, o que significa que não há fundo.

1options.setEmbedFontsAs(FontsConstants.EMBED_FONTS_TYPE3);

O valor predefinido é “TrueType”.
