5.31.2.1 #define FE2_FILTER_OVERLAY
Filter name for use with Flix2_AddFilter() .
Definition at line 76 of file overlay.h.
5.31.2.2 #define FE2_OVERLAY_FILE
Set the path to the overlay image file.
Remarks:
Only PNG images, 24 bit bitmaps, and 32 bit bitmaps are supported. Use of PNG images is highly
recommended.
Images with an uneven width or uneven height will be cropped.
Overlay images larger than the video image will be cropped.
When both the video and overlay images contain an alpha channel, the overlay and video alpha will
be averaged. For example, if the video at the overlay position was fully transparent, and the overlay
was fully opaque, the region of the exported video where the overlay was placed would become 50%
opaque.
