Convert Font to Images

Given a font file called font.ttf, use the following to extract the letters and numbers as separate image files.

for i in {a..z} {A..Z} {0..9}; do convert -font font.ttf -pointsize 72 label:$i $i.gif; done

Identify an Image

Using the identify command from the ImageMagick package, we can print out the details of an image:

identify empty.gif

with the sample output:

empty.gif GIF 1x1 1x1+0+0 8-bit PseudoClass 2c 26B 0.000u 0:00.000

Flip and Image Vertically or Horizontally

Flipping an image vertically or horizontally can be done with the mogrify tool:

mogrify -flip image.png # to flip vertically
mogrify -flop image.png # to flip horizontally
