Detailed Description

Iterators over pixels in a frame.

Author:

Date:

This file contains the classes and functions to use pixel iterators in a polymorphic way. Note that pixel iterators are not fast. They are intended to allow for the automatic generation of conversion routines between any pair of pixel formats. Fast conversion functions for specific formats can be written to override the default ones when needed.

bool vidl_has_pixel_iterator

(

vidl_pixel_format

FMT

)

Return true if the pixel format has a valid pixel iterator implementation.

vidl_pixel_iterator* vidl_make_pixel_iterator

(

const vidl_frame &

frame

)

Pixel iterator factory.

Creates a new pixel iterator on the heap The iterator is initialized to the first pixel in the frame

Note:

The user is responsible for deleting the iterator
