rndmbt,
now i understand, thanks :)

Something i forgot to mention is that OR-ing capabilities together is not allowed, so they should
be set separately.

imageBuffer.setCapability(ImageComponent2D.ALLOW_IMAGE_READ);
imageBuffer.setCapability(ImageComponent2D.ALLOW_IMAGE_WRITE);
drawRaster.setCapability(Raster.ALLOW_IMAGE_WRITE);
drawRaster.setCapability(Raster.ALLOW_IMAGE_READ);
drawRaster.setCapability(Raster.ALLOW_SIZE_READ);
drawRaster.setCapability(Raster.ALLOW_SIZE_WRITE);

Best regards,
basti
