  • Scale an image keeping the original aspect ratio to a maximum dimension of 640x480:

convert {{image.png}} -resize 640x480 {{image2.png}}

  • Horizontally append images:

convert {{image1.png}} {{image2.png}} {{image3.png}} +append {{image123.png}}

  • Vertically append images:

convert {{image1.png}} {{image2.png}} {{image3.png}} -append {{image123.png}}

  • Create a gif from a series of images with 100ms delay between them:
