Preserved Topic: Images in PHP (Page 1 of 1)

Have any of you used PHP to generate images, and is it worth trying to learn? Do you know any good examples or tutorials?

Thanks

I think I am missing something here, what do you mean to have PHP generate images?

Generate images based on a random pixel generating formula?
-I wouldn't recommend ever doing this, you will normally get garbage, and you would have to spend time working with the hex values to determine the way that the pixels are generated, in the format you are looking for, would appear to be an effort of futility to me.

Maybe to generate pictures based on a file that is compressed picture data?
-May be a good idea for storing the picture on disk if space is an issue, but I don't believe that the time spent by the server decompressing it would be worth the time saved.

Or to randomly display a picture that you have saved to disk?
-I would also not recommend this, reason being that Javascript can do all this work on the client side, and if they do not have javascript working then they wouldn't really want to be looking at pictures either.

I don't think these are what you were talking about, but it was a shot in the dark, would you elaborate your question a little bit?

Good luck, good fun,

Oh, now I get it... Bar charts, and graphs.

Well sure learn this! I am sure that it would be a great tool to add to ones arsenal. It would be great for displaying statistics on web usage, or for voting forms, or even for educational, private, or corprate dynamic data presentation (when backended into a wonderfully complex database).

I am sure this would be an extreemly fun thing to learn. I don't know how to do it, but it looks promissing.
