Hi, I want apply a mask to an image. (image and mask have the same dimensions) input.png (grayscale) mask.png I used the next code: convert input.png mask.png -alpha off -compare CopyOpacity -composite out.png The mask was applied correctly, but the out.png lost the grayscale (obviously), i think ...

Thank you ;) After your answers, my solution: 1 - convert in.png to RGBA 2 - I did a loop and i change the alpha values. For example: for i, j in zip(range(255+1), list(reversed(range(255+1)))): (i,i,i,j) (255,255,255,0) (254,254,254,1) (253,253,253,2) ... Thank you ;)

Hi, how can I add a transparency gradient in a grayscale to an image which already have background transparent? For example: white color -> 70% transparent gray -> 40% transparent etc -> etc http://i57.tinypic.com/2mgnsdh.png Thanks
