Matthias Becker created BATIK-1153:
--------------------------------------
Summary: PNGTranscoder creates (visually) different PNGs on Mac or
Windows for same SVG
Key: BATIK-1153
URL: https://issues.apache.org/jira/browse/BATIK-1153
Project: Batik
Issue Type: Bug
Components: SVG Rasterizer
Affects Versions: 1.8, 1.7
Reporter: Matthias Becker
We use the PNGTranscoder to rasterize SVGs into PNG.
We get visually different results when we rasterize the same identical SVG on
Windows and on Mac.
While debugging around I found out that
ConcreteImageRendererFactory#createStaticImageRenderer creates different
Implementation on Mac / Windows. This was implemented because of
https://issues.apache.org/jira/browse/BATIK-593?jql=project%20%3D%20BATIK%20AND%20text%20~%20Mac
.
I now did create StaticRenderer and MacRenderer on Mac and Windows machines (by
directly calling the constructor).
These are the results:
* StaticRender and MacRenderer created visually *different* PNGs when executed
on Mac
* StaticRenderer and MacRenderer produces visually *the same* PNGs when
executed on Windows
* StaticRenderer executed on Mac produces visually *the same* PNG as executed
on Windows
So only the StaticRenderer creates the same results on both platforms.
So my questions:
# Does this performance issue mentioned in
https://issues.apache.org/jira/browse/BATIK-593?jql=project%20%3D%20BATIK%20AND%20text%20~%20Mac
still exist?
# Why does the MacRenderer produce the same result as the StaticRenderer on
Windows but not on Mac?
