Use ImageMagick to place an image inside a larger canvas

Question

Getting started with ImageMagic and trying to find a way to do this... If an image is less than 50 pixels tall or 50 pixels wide, I\'d like to place it (un-scaled) in the horizo

Answer 1

See cutting and bordering for a huge number of examples. Here's one simple way you might do it:

convert input.png -bordercolor Black -border 5x5 output.png

Of course, you'll need to calculate the size of the border to add (if any) based on the dimensions of the input image. Are you using an ImageMagick API, or just the command line tools?
