--- Comment #7 from Patrick Luby <plub...@neooffice.org> --- Update: I finally tracked down where the VirtualDevice is created in the canvas module and approach 1 has no effect. I haven't been able to implement approach 2 yet as I have yet to find where the BitmapEx (and the alpha mask that I need to invert) is drawn. What I see down in the vcl/skia code is that slideshow clears its sprite with white and then draws the shape with its bluish fill. Somewhere there is an alpha mask being filled backwards (white is opaque and black is transparent now) so my theory is that the white clearing creates an inverted alpha mask. I'll keep trying to find where an bitmap with an alpha mask is passed to the vcl/skia code during a slideshow. I would think that all of the fade in drawing would be drawn to a temporary VirtualDevice and then that is drawn with an alpha mask. I haven't been able to grab any stack traces in vcl/skia in the masked bitmaps drawing methods so either no BitmapEx is being drawn or I am looking in the wrong place. -- You are receiving this mail because: You are the assignee for the bug.
