Matthias Becker updated BATIK-1153:
-----------------------------------
Description:
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. I have
attached the SVG and the 4 versions of the rendered PNG.
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?
