81 Each pixel contains 'comp' channels of data stored interleaved with 8-bits
84 The *data pointer points to the first byte of the top-left-most pixel.
92 PNG supports writing rectangles of data even when the bytes storing rows of
93 data are not consecutive in memory (e.g. sub-rectangles of a larger image),
102 HDR expects linear float data. Since the format is always 32-bit rgb(e)
103 data, alpha (if provided) is discarded, and for monochrome data it is
106 TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
107 data, set the global variable 'stbi_write_tga_with_rle' to 0.
109 JPEG does ignore alpha channels in input data; quality is between 1 and 100.
