Re: Apply layer mask w/ transparent result?

Well, I don't know how to explain it, but I ran that transparent command on about 700 images, and then ran composite -compose copy_opacity mask.png image.png result.png They all came out with transparent backgrounds. Best guess is that running that command added an alpha channel to the images. Edit:...

Re: Apply layer mask w/ transparent result?

None of my PNGs had an alpha channel, so I did:

convert -alpha transparent image.png image.png

This fixed it.

Re: Apply layer mask w/ transparent result?

Those commands still don't work for me. Same results. Looks like there's a new binary out, I'll give that a try.

ImageMagick 6.7.7-2 2012-05-25 Q16 on Windows 7 x64.

Re: Apply layer mask w/ transparent result?

Placing the mask first gives me the mask as the result.

Apply layer mask w/ transparent result?

I'm trying to apply a layer mask and remove the background from an image with transparency, and to the best of my understanding, this command should do it. composite -compose CopyOpactiy image.png mask.png result.png However, it just spits out the image, unchanged. http://www.dumpt.com/img/files/oql...
