(PHP 4 >= 4.3.2, PHP 5)

imageantialias --  Should antialias functions be used or not


bool imageantialias ( resource im, bool on )

Activate the fast drawing antialiased methods for lines and wired polygons. It does not support alpha components. It works using a direct blend operation. It works only with truecolor images.

Thickness and styled are not supported.

Using antialiased primitives with transparent background color can end with some unexpected results. The blend method uses the background color as any other colors. The lack of alpha component support does not allow an alpha based antialiasing method.

Note: This function is only available if PHP is compiled with the bundled version of the GD library.
