Wrong CMYK conversion when using text-anchor attribute in svg text/tspan tag

[michele-tolin]

I am using the 67 Version

When the text-anchor attribute is used (directly on the text tag or via css)
the device-cmyk color is not propagated correctly in the final pdf

I'have recreated the case with and without the text-anchor

Original html
test_wrong_cmyk_conversion.html

Converted pdf
test_wrong_cmyk.pdf

Composite preview (made with ghostscript)
wrong_colors1.tif

All 4 channels preview (made with ghostscript)
wrong_colors1(Black).tif
wrong_colors1(Cyan).tif
wrong_colors1(Magenta).tif
wrong_colors1(Yellow).tif

All preview files converted via imagemagick
Composite:

Black

Cyan

Magenta

Yellow

Hi!

Thanks for the report. It’s caused by the way we manage transparency groups, and it’s actually a big problem. We can probably fix this specific problem because there’s no transparency (we only use the group), but it may be much more complicated to fix for other cases.

Looks like we don’t need isolated transparency groups at all, so we should be able to fix this.
