Thanks Patrick for the reply...
But the issue is remain, either I change BufferedImage.OPAQUE,
BufferedImage.BITMASK, or BufferedImage.TYPE_INT_ARGB,
Now I am sending the pdf, please run this code with that pdf,
you can understand my issue more clearly.
So please if u have any suggestion then please suggest me.

Double check that the viewer reference implementation is correstly renderign the PDF in question. If it is rendering ok then you can try the following getPageImage modifcation

Code:

public Image getPageImage(int pageNumber,
                               final int renderHintType, final int pageBoundary,
                               float userRotation, float userZoom) {
         Page page = catalog.getPageTree().getPage(pageNumber, this);
         PDimension sz = page.getSize(pageBoundary, userRotation, userZoom);
 
         int pageWidth = (int) sz.getWidth();
         int pageHeight = (int) sz.getHeight();
 
         BufferedImage image = new BufferedImage(pageWidth,
                 pageHeight,
                 BufferedImage.[b]TYPE_INT_ARGB[/b]);
         Graphics g = image.createGraphics();
 
         page.paint(g, renderHintType,
                 pageBoundary, userRotation, userZoom);
         g.dispose();
         catalog.getPageTree().releasePage(page, this);
 
         return image;
     }

Hi,

First of all I will thanks to the team of ICEPdf, Because now I am able to render PDF version 1.6.
Now I am facing another problem, While I am rendering the pages as images, It is not capturing the transparent images of that pdf page.
At the position of transparent images it is showing white back ground.

I am using the following code:
import org.icepdf.core.exceptions.PDFException;
import org.icepdf.core.exceptions.PDFSecurityException;
import org.icepdf.core.pobjects.Document;
import org.icepdf.core.pobjects.Page;
import org.icepdf.core.util.GraphicsRenderingHints;
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.awt.image.RenderedImage;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;

public class PDFPageCapture {
public static void main(String[] args) {
// Get a file from the command line to open
// String filePath = args[0];
// open the file
Document document = new Document();
try {
document.setFile("D:/Ebook/JpegToPDF/pdf/alberta-justice-success-story.pdf");
} catch (PDFException ex) {
System.out.println("Error parsing PDF document " + ex);
} catch (PDFSecurityException ex) {
System.out.println("Error encryption not supported " + ex);
} catch (FileNotFoundException ex) {
System.out.println("Error file not found " + ex);
} catch (IOException ex) {
System.out.println("Error IOException " + ex);
}
// save page captures 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.PRINT, Page.BOUNDARY_CROPBOX,
rotation, scale);
RenderedImage rendImage = image;
try {
System.out.println(" capturing page " + i);
File file = new File("D:/Ebook/JpegToPDF/images/imageCapture1_" + i + ".gif");
ImageIO.write(rendImage, "gif", file);
} catch (IOException e) {
e.printStackTrace();
}
image.flush();
}
// clean up resources
document.dispose();
}
}
So, Please if any one have any solution, then please suggest me.
