PHP supports a wide range of general manipulation functions for images,
allowing you to copy all or portions of images, resize images, gather information
about images, and more.
- • imagecopy() -- Copy all or a portion of one image onto another
- • imagecopymerge() -- Copies and merges a portion of one image onto another
- • imagecopymergegray() -- A grayscale version of imagecopymerge()
- • imagecopyresized() -- Copy and scale a portion of one image onto another canvas
- • imagecopyresampled() -- Copy, scale, and resample one image onto another canvas
