Thanks for the reply Paulo,
If transparency in Graphics2d should work or mostly like you say then I can figure out what can be done.
Here is a simple code snippet of the general idea;
I want the background to be transparent like it is. The image is just an test image, it can easily be a gif. I've checked but the imageIO doesn't muck up the real image (only if you want to edit :P).
public class Test {
public static void main(String args[]) {
try {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, intermediateStream);
document.open();
PdfContentByte contentByte = writer.getDirectContent();
DefaultFontMapper mapper = new DefaultFontMapper();
PdfTemplate template = contentByte.createTemplate(240, 170);
Graphics2D g2d = template.createGraphics(240, 170, mapper, true, 1.0);
//test PNG image
//http://images.linux.com/babytux.png
FileInputStream fileInputStream = new FileInputStream("C:/babytux.png");
BufferedImage image = ImageIO.read(fileInputStream);
//if skipped background on GIF and PNG are black
if (image != null && (image.getType() == BufferedImage.TYPE_BYTE_INDEXED || image.getType() == BufferedImage.TYPE_CUSTOM)) {
BufferedImage bufferedImage= new BufferedImage(image.getWidth(), image.getHeight(), BufferedImage.TYPE_INT_ARGB);
Graphics2D g = bufferedImage.createGraphics();
g.setColor(g.getColor());
g.fillRect(0,0,image.getWidth(),image.getHeight());
g.drawImage(image, 0, 0, null);
g.dispose();
image = bufferedImage;
}
g2d.drawImage(image, 0, 0, 100, 200, null);
g2d.dispose();
contentByte.addTemplate(template, 0, 0);
document.close();
} catch ( Exception e ) {
e.printStackTrace();
}
}
}
Is there something I can try?
Greetings flattened Peter
