This may be a crazy and worthless idea:
I noticed the image-x-generic icon
(http://fedoraproject.org/wiki/Artwork/EchoDevelopment?action=AttachFile&do=get&target=image-x-genericL.png)
contains an embedded bitmap
(http://fedoraproject.org/wiki/Artwork/EchoDevelopment?action=AttachFile&do=get&target=landscape.jpg).
How about using a vectorized version of the bitmap?
The downside is the SVG resulted after tracing loses a lot of details
and have a large file size, but is much easier to work with it in a
vector application.
The bitmap after tracing:
http://fedora.nicubunu.ro/echo/landscape_traced.svg
The image-x-generic icon using the traced vector image instead of bitmap:
- SVG: http://fedora.nicubunu.ro/echo/image-x-genericL_traced.svg
(yes, is full vector)
- PNG: http://fedora.nicubunu.ro/echo/image-x-genericL_traced.png
note: I have no shadow and the outline is not quite the same, this can
be corrected easily.
