;Pixel storage order
;Pixel storage order
:Below you can see the pictures for this example. The first picture shows how it's stored in Oni, the second how you see it in the game.
:Pixels are stored in row-major order, meaning that all the pixels forming a scanline (image row) are grouped together (stored in left-to right order); the rows are stored in bottom-to-top order (see illustration below).
 
:In the case of the DXT1 storage format, the row-major, left-to-right, bottom-to-top order applies to the 4x4 blocks composing the image, and also inside each 4x4 block for the storage of 2-bit pixels.
:In the case of the I1 format (several pixels per byte), the row-major, left-to-right, bottom-to-top order applies to the 1-bit pixels composing the image.

;RGBA_Bytes (format N°11)
*Four consecutive 8-bit fields are used to store 4 color channels (8 bits each, values from 0 to 255).
*Each channel has its own byte. Endianness is irrelevant when storing as a sequence of bytes.
