manipulating images

combining images


  • foobar.png represents a combined output image.

For sequentially-named images in a single directory, use convert -append *.png foobar.png to combine images vertically or convert +append *.png foobar.png to combine images horizontally.

rotating images


  • foo.png represents an unrotated input image.
  • bar.png represents a rotated output image.
  • baz represents the rotation angle to be applied. Recommended values are:
    • 90
    • 180
    • -90
    • -180

Use convert foo.png -rotate baz bar.png.
