Saša Makorič updated BATIK-1369:
--------------------------------
Summary: Incorrect rasterization of colored mask (was: Incorrect
rasterizering of colored mask)
> Incorrect rasterization of colored mask
> ---------------------------------------
>
> Key: BATIK-1369
> URL: https://issues.apache.org/jira/browse/BATIK-1369
> Project: Batik
> Issue Type: Bug
> Components: SVG Rasterizer
> Affects Versions: 1.12, 1.17
> Reporter: Saša Makorič
> Priority: Major
> Attachments: example.png, example.svg, output-values.png
>
>
> When rasterizing an SVG to a PNG (or any other format, it doesn't matter),
> the output image shows slight changes in the RGB values and the alpha channel.
> h4. How to reproduce:
> * Create an SVG with a masked rectangle filled with color (see example.svg)
> and another rectangle filled with the same color.
> * Transform the SVG into a PNG using the following command:
> {code:java}
> java -jar batik-rasterizer-1.17.jar -m image/png -w 800 -d output/
> example.svg{code}
> * Check the output file (example.png). You will notice that the two
> rectangles have differences in their RGB values and alpha channels
> (output-values.png).
>
> The resulting differences are very small but impact the fidelity of the
> values, especially when using more complex SVGs where layers overlap, making
> the differences considerably more noticeable.
