[iText-questions] Graphics2d + transparency

[Peter van Raamsdonk]

Anybody any transparent thoughts on this...

 

I'm using buffered images to draw on Graphics2d generated from the PdfContentByte. The buffered images are type ARGB (source PNG, GIF) and they contain transparency if I check image.getColorModel().getTransparency().

 

To check the transparency further I even replaced all transparent areas with an other color.

 

However when generating the pdf the transparency is turned into a solid color.

 

If I use a template with PdfGState and set the blendmode to BM_MULTIPLY transparency is achieved simular to Photoshop. However the downside is that the layers of individual images or text get mixed.

My question:

Does transparency for Graphics2d work? If it works what am I doing wrong? If it doesn't work when will it be fixed?
