Awesome. Thanks a lot! Our default submission procedure would be if you uploaded the patch to reviewboard:
https://git.reviewboard.kde.org/dashboard/ Looking at the patch I wonder whether the (performance critical) blending of the pixel in MergedLayerDecorator should only be performed if the pixel is not opaque. So the "old" implementation would still be called for opaque pixels while your new implementation would be called for semitransparent pixels. On and a fully transparent pixel wouldn't require a scanline call of course ..

Sadly it looks like marble discard the alpha channel at some place (IMHO it could be in ImageF.cpp) and displays the background in black. That's not quite satisfactory since I'd like to simply add some visual information to the OSM theme. Is it possible to fix this or can I use some other feature to display an overlay with transparent background? regards Knut _______________________________________________ Marble-devel mailing list [email protected] https://mail.kde.org/mailman/listinfo/marble-devel _______________________________________________ Marble-devel mailing list [email protected] https://mail.kde.org/mailman/listinfo/marble-devel
