Subject Problem in rendering PNG images with ImageLoaderRawPNG in XMLGraphics 2.0.1 and FOP2.0
Date Thu, 05 Nov 2015 09:02:35 GMT
Hi,

I am migrating from FOP 1.0 to FOP 2.0

I have made the required Java code changes as per the changed API.

There are PNG images used in the report generated using PDF renderer..

Initially with FOP 1.0, I tried ImageLoaderPNG. However, the resolution of the image gets
impacted. So I shifted to ImageLoaderRawPNG which rendered it properly.
Attaching the files.
1) graph.png - The original PNG image
2) FOP-PNGImageLoader-differences.docx - The rendered images with ImageLoaderPNG and ImageLoaderRawPNG

So this was working fine with FOP 1.0
However, FOP 2.0 is not able to render the image with ImageLoaderRawPNG and throws following
exception..
