ImageGear is equipped with several functions that let you get and set the values of individual pixels, rows or columns of pixels, and rectangular groups of pixels. This family of functions is referred to as the "pixel access" functions.

All functions include the acronym "DIB" in their names. Every pixel access function is part of a "_get()/_set()" pair of functions. In other words, for each pixel access type, you can obtain the value(s) of a pixel or group of pixels, and set the value(s) of a pixel or group of pixels.

To obtain descriptions of each pixel access function and view additional sample code, refer to the Core Component API Function Reference.
