.txt to .png

Hey guys

Quick question,
What are my chances of being able to convert a txt file on a sever, to a png file?

Say for example I have a txt file with a bunch of pixel information in it... eg:
one pixel = 33ff55
text file contains = 33ff5533ff5533ff5533ff55
(note, output png file will have no transparency)

At the moment I have a server-side drawing app reading each pixel from the txt file, converting the hex codes into rgb, and then drawing a png file pixel by pixel... it works, but it takes wayyy too long...

Anyone have thoughts on this?

You can do so with graphic libraries.
The latest PHP compiles include the GD graphic library..

Go to http://www.php.net/ and type image in the search box.

You will find documentation about all the available functions.

Give more attention to user comments: they are packed with sample codes...
