Legacy ImageMagick Discussions Archive

I have a website with thousands of images. I would like to allow someone to upload an image and let them "search" by it returning "matches". Can imagemagick do this? I would need to store something for each of my images, and then compare that with the same something from the search image. Is this a ...

Thanks for the info...I will look at putting a -limit-memory in place. According to the resource list I have 1.5gb...I am assuming I should just set something like 10mb (most files that are processed are less than 4mb).

I have 2 commands that function correctly independently. I have tried to use the miff command to chain them, but I get an error (below). I also cannot figure out how to "merge" them. First: (pretty simple, just applies the overlay to image and saves as result) composite -gravity center overlay.png ...
