Can't get animated GIF transparency.
Posted: Sun Nov 21, 2010 1:30 am
Hello.
I'm trying to generate a multi-sequence animated GIF with a transparent region surrounding the morphing images. The input is a pair of PNGs with alpha channels as appropriate. It seems to be right in the preview window, with the gray-hatched background in the transparent areas, but when it is rendered, that area is black. (It shows as black in the preview window during rendering, but not during editing/previewing).
The "Export transparent gif" box is checked. The threshold slider does not affect the result.
Background colors and images work properly; they occupy the area I am trying to make transparent. If nothing is set for a background, however, it defaults to black.
Sequence and Movie effects both have alpha set to zero. "Highlight overlapping areas" is checked for all sequences.
Any ideas?
(FM version: 4.2.6 Deluxe)
(Also a suggestion: In a future release, please consider removing black dots from the color-cycle option. They tend to get lost in images very easily.)
