在这里，你打开一个jpg文件并逐个像素地吐出。


此刻，输出发送如果你愿意的话，你可以打开一个文件并将其转储

。


输出是逐行的，6 chr hex color

格式：

rrggbbrrggbbrrggbb


<？php

imgFile =" icon_ar.jpg" ;;

Running Apache2 and PHP 4.3.3 on Windows, is there any way that I can
have PHP read an image file and out put its color content?

Preferably, I would like for it to read a .bmp file and output a text
file of the color codes for each pixel of the image.
I can convert it to a .jpg or a .gif if need be, but I would prefer to
stay with the .bmp if its possible.

Any help is greatly appreciated.

Here you go, this one opens up a jpg file and spits out pixel by pixel.

at the moment, the output is send to screen, you can open a file and dump it
there instead if you wish.

the output is row by row, and 6 chr hex color
format:
rrggbbrrggbbrrggbb

<?php

imgFile = "icon_ar.jpg";
