Detect background color and create square image
Posted: 2014-12-18T14:32:12-07:00
Hi everyone!
I may be asking too much here but let me explain what I'm trying to do.
1.) User uploads photo
2.) Detect if the image has a solid background (most likely a logo) or if not (most likely a photograph)
3.) If it's a logo with a solid background, determine the background color
4.) if the image is not a perfect square, and a "logo" make the image a square using the script below with the determined background color.
Is this possible with imagemagick?
