These operations convert an image in some way. They can be split into twomain groups.
The first set of operations change an image’s format in some way. You canchange the band format (for example, cast to 32-bit unsigned int), formcomplex images from real images, convert images to matrices and back, changeheader fields, and a few others.
The second group move pixels about in some way. You can flip, rotate,extract, insert and join pairs of images in various ways.
