Hi,
I am using ImageRenderInfo for parsing PDFs and getting ImageBytes but for
my perticular PDF file which has one big PNG image in it nothing else, the
ImageRenderInfo.getImage() gives nothing if I save the bytes as .png on
filesystem the image is all black.
Here is the code.
public void renderImage(ImageRenderInfo renderInfo)
{
cnt++;
try
{
// String filename;
// FileOutputStream os;
PdfImageObject image = renderInfo.getImage();
if (image == null) return;
//filename = String.format(path,
renderInfo.getRef().getNumber(), image.getFileType());
// os = new FileOutputStream(filename);
// os.write(image.getImageAsBytes());
byte [] pageImageBytes = imageMap.get(pageNumber);
if(pageImageBytes == null)
{
pageImageBytes = new byte[image.getImageAsBytes().length];
System.arraycopy(image.getImageAsBytes(), 0, pageImageBytes, 0,
image.getImageAsBytes().length);
imageMap.put(pageNumber, pageImageBytes);
//java.io.InputStream _in = new
ByteArrayInputStream(pageImageBytes);
//BufferedImage im = ImageIO.read(_in);
ImageIO.write(image.getBufferedImage(), "png", new
File("/Users/ayeole/Desktop/images/Img"+cnt+".png"));
}
else
{
byte [] newBytes = new byte[image.getImageAsBytes().length +
imageMap.get(pageNumber).length];
System.arraycopy(image.getImageAsBytes(), 0, newBytes, 0,
image.getImageAsBytes().length);
System.arraycopy(imageMap.get(pageNumber),0,
newBytes,image.getImageAsBytes().length, imageMap.get(pageNumber).length);
imageMap.put(pageNumber, newBytes);
}
// os.flush();
// os.close();
}
catch (IOException e)
{
System.out.println(e.getMessage());
}
}
Please let me know if you anyone has any solution for this...
