# I want to resize an image from 600x128 to 225x100 while keeping its aspect ratio. | |
# Resizing the width to 225 while keeping the aspect ratio makes one dimension (height) | |
# smaller (225x48) than what I want to obtain (225x100). | |
# The workaround is to resize first, | |
# then increase the canvas of the other dimension (height) | |
# to obtain the desired size (225x100) then center the image in the canvas. | |
