Description:
------------
I'm currently developing a program that involves a lot of classes. When I have to draw one on an image with GD, a method one call a parent class method, and this parent another parent and on and on... 

If I put to many "links" of a class in another, the GD image will lose some rectangles, lines, text strings... and other rectangles appear black filled. 

When I change imagecreate() by imagecreatetruecolor(), it's working fine.

I'm currently using WinXP with Apache2, PHP5.0.2 (php-cgi.exe) with the GD2 library php_gd2.dll (provided by PHP).
I was wondering if it was a problem with memory... in php.ini, I've set the maximum memory to more than 8M but it didn't work anymore.

Reproduce code:
---------------
I really tried to do a little code to reproduce the error but I've spent about 2 hours in vain...
My code is not free and I don't want to post it here. To whom may I send it (email... ?)?

You reached the maximum amount of colors you can have. Using a truecolor you do not have real limits. Read the manual for further informations.

Only using black and white image.
I have the zip of the code. To who I have to send it ?
Contact me by email if you want.

> Only using black and white image.

You mean that:
- you allocate only 0 and 255,255,255? (that means no grayscale)

- you do not allocate again and again the same color
  in each function/class/whatever?

> I have the zip of the code. To who I have to send it ?

No need to see code, you clearly reached the limit of your current palette (max is 255 colors + bg), even if you are using 128 times white and 128 times black.

pass the index of the color as the argument and not the value of RGB.

Please keep it bogus, it's clearly a misusage.

It's not written at all in the documentation... that we can use only 255 colors (even if we use the same color with multiple calls of imagecolorallocate). Or, why no warning when allocating ?
