Subject [jira] [Updated] (XGC-102) Problem in rendering PNG images with ImageLoaderRawPNG in XMLGraphics 2.0.1 and FOP2.0
Date Sun, 22 Nov 2015 22:04:11 GMT

     [ https://issues.apache.org/jira/browse/XGC-102?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.

>          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.
