IMAGEMAGICK, examples which illustrate the use of IMAGEMAGICK, which is a program that can create, edit, compose or convert graphical information as stored in many different file formats. IMAGEMAGICK can resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.
The file balloons_noisy.png contains a lot of speckle noise. We remove most of the noise using the ImageMagick convert command with the "-noise 3" switch. We make versions of the image with just 2, 4, 8 or 16 colors using the "-colors n" switch. We left-right reverse the image with the "-flop" switch.
