Pixel display format

Pixel display formats like *.bmp, *.gif, *.tif store an array of entries, with each entry representing one pixel. This is usually done by storing a 32-bit word in RRGGBBAA format, where 0<=RR<=255 0<=GG<=255 0<=BB<=255 0<=AA<=255 RR represents the red intensity, BB represents the blue intensity, GG represents the green intensity, and AA represents the alpha (transparency).
