[PHP-DOC] #21834 [NEW]: First call to imagecolorallocate() assigns background From: Brendan <email protected>
Date: 01/22/03

From: Brendan <email protected>
Operating system: Win2k
PHP version: 4.3.0
PHP Bug Type: Documentation problem
Bug description: First call to imagecolorallocate() assigns background

I discovered from experimentation that the first call to
imagecolorallocate() for a given image, sets the background colour for
that image.

This would be worth noting in the manual page for imagecolorallocate().
Someone has pointed it out in a user comment, but it is a fairly important
aspect of the function's behaviour, and IMO should be part of the official
documentation.

I'm using php_gd2 as bundled with PHP 4.3.0, and I've only tried PNG
images so far. I can't say for sure if imagecolorallocate() exhibits this
same behaviour for other image types.

As an aside, the GD functionality is great. I'm loving the idea of
creating dynamic images in my app.

May the Force be with you.
