About the Page Capture Example

The Page Capture example demonstrates how to use the ICEpdf Document class to capture PDF page renders as image files. Once a file has been opened, the document pages can be iterated over, to generate an image capture of each page.

The source-code for this example is located at:

A primer on using Maven or Gradle build commands can be found here (Maven) and here (Gradle)

// save page caputres to file.
float scale = 1.0f;
float rotation = 0f;

// Paint each pages content to an image and write the image to file
for (int i = 0; i < document.getNumberOfPages(); i++) {
    BufferedImage image = (BufferedImage)
            document.getPageImage(i,
                                  GraphicsRenderingHints.SCREEN,
                                  Page.BOUNDARY_CROPBOX, rotation, scale);
    RenderedImage rendImage = image;
    // capture the page image to file
    try {
        System.out.println("\t capturing page " + i);
        File file = new File("imageCapture1_" + i + ".png");
        ImageIO.write(rendImage, "png", file);

    } catch (IOException e) {
        e.printStackTrace();
    }
    image.flush();
}

Make sure to always call document.dispose() when you are done processing a PDF document. Dispose cleans resources used by the document object.
