GLSRGB8ALPHA8

GLSRGB8ALPHA8 is a pixel format used in computer graphics and image processing. It is a 32-bit format, meaning each pixel is represented by 32 bits of data. The format is divided into four channels: red, green, blue, and alpha. Each channel is allocated 8 bits, providing 256 possible values for each channel.

The red, green, and blue channels are used to represent the color of the pixel. The alpha channel, on the other hand, represents the transparency or opacity of the pixel. A value of 0 in the alpha channel indicates complete transparency, while a value of 255 indicates complete opacity.

The "GLS" prefix in the format name stands for "Gamma-corrected Linear Space." This means that the color values in the red, green, and blue channels are stored in a linear space, but they are interpreted as if they were in a gamma-corrected space. This is done to improve the accuracy of color representation on displays that use gamma correction.

GLSRGB8ALPHA8 is commonly used in graphics APIs such as OpenGL and Vulkan, where it is used to store and manipulate image data. It is also used in image file formats such as PNG and JPEG, where it is used to store and transmit image data.
