And little endian should work! x86 64bit. so it's broken on little endian x86... 64bit though. :) > On 02/26/2014 08:18 PM, Carsten Haitzler (The Rasterman) wrote: > > On Mon, 24 Feb 2014 08:51:24 +0100 Hendrik Siedelmann > > <hendrik.siedelm...@googlemail.com> said: > > > > oh. cool bananas! thought i think you have some bugs... : > > > > http://www.enlightenment.org/ss/e-530e3cdc1434c8.05020334.png > > > > :) your argb byte ordering is... broken when messing with the image > > pixels. :( > > > > rememebr that with evas (and efl) pixels are INTS not bytes. int. an int is > > 32bit. the MSB (high byte withn the int) is A, then R then G then B ie for > > 32bits the bits rom highest to lowest are: > > > > AAAAAAAARRRRRRRRGGGGGGGGBBBBBBBB > > > > or > > > > int pixel; > > > > a = (pixel >> 24); > > r = (pixel >> 16) & 0xff; > > g = (pixel >> 8) & 0xff; > > b = pixel & 0xff; > > > > and reverse: > > > > pixel = (a << 24) | (r << 16) | (g << 8) | b; > > :) > > > > yes... you can access byte by byte too - but you need to account for > > endianess then as it changes between x86 and ppc, mips, some arm > > implementations etc. etc. :) there ae macros in evas src like A_VAL(), R_VAL > > () G_VAL() that do this internally as needed if you look. :) then macros > > for merging together again. > > > >> Hello everybody! > >> > >> I present you a image editing tool/library for e!
