Hi
I've got some problems with setting images transparent. I have a
png-file and a pdf-file. The png is the base layer and the pdf overlays
the png. The white parts of the pdf should be transparent not white
anymore. Here's the code:
URL PdfUrl = new URL("........");
PdfReader reader = new PdfReader(PdfUrl);
Document document = new Document(new Rectangle(width,height));
PdfWriter writer = PdfWriter.getInstance(document, new
FileOutputStream("out.pdf"));
writer.setPdfVersion(PdfWriter.VERSION_1_2);
document.open();
PdfContentByte cb = writer.getDirectContent();
document.newPage();
PdfImportedPage tp = writer.getImportedPage(reader, 1);
Image img = Image.getInstance(tp);
img.scalePercent(percent);
//nothing happens here
//int[] transp = {255, 255, 255, 255, 255, 255};
//img.setTransparency(transp);
URL rasterUrl = new URL(".......");
Image imgRaster = Image.getInstance(rasterUrl);
imgRaster.setAbsolutePosition(marginXp+marginTitelp, marginYp);
cb.addImage(imgRaster);
img.setAbsolutePosition(marginXp+marginTitelp, marginYp);
cb.addImage(img);
All I see is the imported pdf-file. I tried the setTransperancy method,
but nothing happened.
Thanks for your help.
Regards
Stefan
