Hi all, Here are some tiny patches to fix bugs in SVG import.
0001: Check opacity for == operator Sometimes, LilbreOffice doesn't handle opacity value. Example: http://gnome-colors.googlecode.com/svn/trunk/gnome-colors/gnome-colors-common/scalable/actions/document-properties.svg The patch fixes this problem. 0002: Fix color serialization Sometimes, LibreOffice fails to import fill or stroke colors (when using File -> Open) Example: http://gnome-colors.googlecode.com/svn/trunk/gnome-colors/gnome-colors-common/scalable/actions/edit-redo.svg Treat color value as hex. 0003:Relax paint url parsing (fix fdo#34205) LibreOffice doesn't allow ' or " between "url(" and "#". As a result, gradients using url('#foo') syntax aren't imported. Bug 34205 – SVG import: transparency gradients incorrect https://bugs.freedesktop.org/show_bug.cgi?id=34205 0004: Ensure writing styles for text Currently, when a text element doesn't have presentation attributes or styles, style information is not written (when using File -> Open). So the text has zero width and is wrapped wrongly. This patch ensures that filter writes style information if a text has no styles. See attached text3.svg. Black text ("Hello") will be wrapped wrongly. All patches are under LGPLv3 / MPL. cheers, -- Kurosawa Takeshi <taken....@gmail.com>
