Re: SVGs with alpha channel transparency

[John Pye]

Hi Uwe, This approach (save as PDF from Inkscape) did not give me alpha channel transparency in my PDF. For example: On the left is a PNG exported from Inkscape (or alternatively, generated using 'rsvg-convert'. On the right is the PDF exported by Inkscape. So I'm still stuck with no alpha channel; the only approach still is to use a PNG conversion filter, which means blurry figures. I'm hoping that rsvg-convert's PDF output might do a better job than Inkscape's, but haven't succeeded with that (the LyX builtin 'convert' convert seems to get in the way for some reason).

Transform your SVG to PDF. Inkscape supports alpha channels in SVG and in PNG, see http://wiki.inkscape.org/wiki/index.php/InkscapeFeatures The new version 0.44 of Inkscape: http://sourceforge.net/project/showfiles.php?group_id=93438&package_id=99112 comes with a native PDF export, so that the alpha channel should be included in the PDF. The resulting PDF image can directly be used in LyX when you use pdflatex to generate the PDF output. regards Uwe -- John Pye Department of Mechanical and Manufacturing Engineering University of New South Wales, Sydney, Australia http://pye.dyndns.org/
