How to remove black border around transparent image in PDF created by iText

I have searched over bunch of sites, and I was unable to find solution for my problem.

This is the problem: I am making PDF's in Java using iText library. Everything works fine except one thing. Transparent PNG images have black/gray border around non-transparent area. I didn't set any borders in code, and actually I have tried to remove them (with no luck).

Can someone help me how to solve this problem?

The closest answer what I have found is: Resizing an image in asp.net without losing the image quality But I cannot (don't know) interpret this code in Java.

My code is pretty big to copy/paste, but these are steps:

  1. create document
  2. load image from given path
  3. manipulate image (resize, rotate, positioning)
  4. add image to current page
  5. save pdf file

This is what I have tried also:

Thanks in advance

UPDATE: I forgot to mention that my original pictures don't have border. Border is created somehow by iText. I initially thought that it was bug, but since iText 5.0.2 this problem remained so now I doubt that is bug (I am currently using 5.1.3).

UPDATE 2 I forgot to add this link: http://itext-general.2136553.n4.nabble.com/template/NamlServlet.jtp?macro=print_post&node=2157261 Here is presented VB script that works, but I cannot convert to Java code (it still draws black border), so can someone help me at least with this to convert good?

You could use the java BufferedImage method, getSubImage(x, y, w, h) which allows you to crop a sub image out of an existing image. That way you could cut out the edges.

See here: Class BufferedImage
