High! I am doing a nice alpha blended overlay on my movie... I am currently loading a 24 bit tif for the RGB and then another 24bit tif for the alpha channel. Is there no filter out there that can just load a 32bit image with the alpha layer already there???

I can create a 32bit tiff that has RGB and ALPHA, but all the image loaders seem to be limited to 24bit.

I am not using colormask, but an creating my own detailed mask in a graphics editor. If a 32bit image loader does not exist, could someone please wite one?? I promise to release all my perl scrips involving avisynth as I get them working.

-Thanks HighInBC

I believe Richard is working on image importing ATM.

Anyway, for the time being, save your alpha-channel as a separate file, and use the Mask function to merge the images together.

Thanks, that is what I am doing now. It has all the functionality, but a 32bit image loader would save several stops.

I just committed BMP support (export only). Only RGB24 and RGB32 are currently working, but every colorspace will be supported soon, along with compressed image formats (PNG and JPEG).

I'd planned to finish all of the compressors/exporters before starting to port over the decompressors/loaders, but a quick 32-bit loader wouldn't be too hard... :)

You rock! Keep up the good work. I am amazed at the video effect that can be accomplished with avisynth.

Nice!! I'll see if I can get time to update the cvs page. Talking about releases - where did I put the 2.08 release I promised ;)

Hey, I need to do a similar thing I guess, but not needing 32-bit :). Could someone tell me how I can load an image sequence into avisynth? Like a bunch of frames FRAME##.BMP.
