In computer graphics, pixels encoding the RGBA color space information must be stored in computer memory (or in files on disk). In most cases four equal-sized pieces of adjacent memory are used, one for each channel, and a 0 in a channel indicates black color or transparent alpha, while all-1 bits indicates white or fully opaque alpha.

The smiley face in the top left corner is a raster image. When enlarged, individual pixels appear as squares. Enlarging further, each pixel can be analyzed, with their colors constructed through combination of the values for red, green and blue.
No Compression. Image data starts at byte 512 in file. Data length can be calculated using the following: (X size) × (Y size) × (Num. of channels) × (Bytes per channel)

1931 CIE chromaticity diagram showing some RGB color spaces as defined by their chromaticity triangles. RGB color spaces is a category of additive colorimetric color spaces [1] specifying part of its absolute color space definition using the RGB color model.
sRGB is a standard numerical encoding of colors, based on the RGB (red, green, blue) color space, for use on monitors, printers, and the World Wide Web.It was initially proposed by HP and Microsoft in 1996 [2] and became an official standard of the International Electrotechnical Commission (IEC) as IEC 61966-2-1:1999.
