Re: Images-weird!!

No, this is not the problem. $i and $j start from 0, anyway. The real problem, as I see it, is the following: I have a big loop, to create something like a checkerboard, but with 13 or so colors. If the loop iterates more than 256 times, then those cells with indexes bigger than 255 (or 256, does not matter) will have a single color: that of the 255th or 256th cell. It is as if I do not have only 13 colors, but 256! Try to run the code and see what I mean. Now I try to do my job by using JPGraph, but I succeded to ruin everything:) Oh, dear:) On Mon, 3 Feb 2003, Adam Royle wrote: > Hi Mihai, > > Didn't try your code, but noticed your comment on colours.
