Luis Bernardo updated XGC-102:
------------------------------
Attachment: graph1icc.png
There was indeed a regression with FOP 2.0. That has been fixed in trunk. The
issue with color fidelity is not due to a gamma transformation but just
different color spaces used by different image loaders.
So you need to use trunk. Another alternative not so simple is to embed an ICC
color profile in the PNG image and use the default image loader (in principle
FOP will use the embedded profile instead of a default one). I have done that
myself and the result seems similar to the original. See attached image
graph1icc.png.

> Project: XMLGraphicsCommons
> Issue Type: Bug
> Components: general
> Affects Versions: 2.0.1
> Environment: FOP 2.0., PDF rendering of a PNG Image using
> ImageLoaderRawPNG
> Reporter: Mandar Nimbkar
> Fix For: 2.0.1

> 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.
> So this was working fine with FOP 1.0
> However, FOP 2.0 is not able to render the image with ImageLoaderRawPNG and
> throws exception..
> Attached the PNG image, exception and the intermediate XSL-FO file (partial)
> generated with ImageLoaderRawPNG.
