c - Why pixels are copied backwards? -

i have function converts .bmp .ppm. since .ppm doesn't need padding @ end of each row of pixels, have loop skips padding , writes each pixel .ppm file. however.. copied backwards. rgb->bgr. don't know why, thought fwrite writes bytes in sequence.

for(h = height*((width*3) + width%4); h>=0; h -= (width*3) + width%4) { fwrite(&bmpdata[p->__index][54 + h], 1, width*3, fp); }

bmpdata 2d buffer containing .bmp file.

54 offset of pixels starts from.

what doing wrong?

c bitmap buffer pixels
