/picstr 1 string def

12 12 1 [12 0 0 12 0 12] {currentfile picstr readhexstring pop} image
<image data here>

when i use the above code the image is rendered  correctly, but if I change the
length of picstr to anything other than one (I tried several values) the code ceases to work, what am I doing wrong? what values could I use for the length of picstr?

Please note that the height and width of the image can vary greatly from a few points
to hundreds of points. I used 12 just for illustrative purposes.

Thanx

Ross
