Byte-level operations
[Pixel Iterators]


Detailed Description

Byte-level operations on pixel iterators.

Support for pixel iterator movement measured in raw bytes (as opposed to pixel type).
Necessary to handle image row alignment and channel plane alignment.


Modules

 byte_step
 returns the number of bytes from the current pixel of a pointer to the next
 byte_distance
 Returns the distance in bytes from the first pixel iterator to the second.
 byte_advance
 Moves a pixel iterator a given distance in bytes.
 byte_advanced
 Returns a pixel iterator a given byte distance away from a given pixel iterator.
 byte_advanced_ref
 Shortcut to advancing a pixel iterator by a given number of bytes and taking the reference in case the compiler is not smart enough.
