Tilman Hausherr commented on PDFBOX-2654:
-----------------------------------------
The java library is playing games on us, here's some debug output:
{code}
bi.getColorModel().hasAlpha(): true
bi.getAlphaRaster(): null
{code}
I'll test some workaround. Btw, the problem can be reproduced with just 2 lines
of code:
{code}
BufferedImage awtImage = ImageIO.read(new File(......));
new PDPixelMap(new PDDocument(), awtImage);
{code}
> Null Pointer exception while reading a gif file
