PrintedPdfDocument


public class PrintedPdfDocument
extends PdfDocument

java.lang.Object
   ↳ android.graphics.pdf.PdfDocument
     ↳ android.print.pdf.PrintedPdfDocument


This class is a helper for creating a PDF file for given print attributes. It is useful for implementing printing via the native Android graphics APIs.

This class computes the page width, page height, and content rectangle from the provided print attributes and these precomputed values can be accessed via getPageWidth(), getPageHeight(), and getPageContentRect(), respectively. The startPage(int) methods creates pages whose PageInfo is initialized with the precomputed values for width, height, and content rectangle.

A typical use of the APIs looks like this:

 // open a new document
 PrintedPdfDocument document = new PrintedPdfDocument(context,
         printAttributes);

 // start a page
 Page page = document.startPage(0);

 // draw something on the page
 View content = getContentView();
 content.draw(page.getCanvas());

 // finish the page
 document.finishPage(page);
 . . .
 // add more pages
 . . .
 // write the document content
 document.writeTo(getOutputStream());

 //close the document
 document.close();

Returns
Rect The content rectangle. This value cannot be null.

getPageHeight

Added in API level 19
public int getPageHeight ()

Gets the page height.

int The page width in PostScript points (1/72th of an inch). Value is 0 or greater

startPage

Added in API level 19
public PdfDocument.Page startPage (int pageNumber)

Starts a new page. The page is created using width, height and content rectangle computed from the print attributes passed in the constructor and the given page number to create an appropriate PageInfo.

After the page is created you can draw arbitrary content on the page's canvas which you can get by calling Page.getCanvas(). After you are done drawing the content you should finish the page by calling PdfDocument.finishPage(android.graphics.pdf.PdfDocument.Page). After the page is finished you should no longer access the page or its canvas.

Note: Do not call this method after PdfDocument.close(). Also do not call this method if the last page returned by this method is not finished by calling PdfDocument.finishPage(android.graphics.pdf.PdfDocument.Page).

Parameters
pageNumber int: The page number. Must be a non negative. Value is 0 or greater
