Hi everyone,
I've created an image in RGB from ImageMagick, it's 4 by 4 so I'm
expecting 48 numbers (4*4*3). [width*height*(R,G,B)]
When I read the file with PHP and unpack it I get between 330 and 333,
I guess this difference is down to headers and end of file data. Is
there anyway to access only the useful image bits, those 48 numbers?
Thank you,
Nicholas Cooper
