imageantialias

(PHP 4 >= 4.3.2, PHP 5)

imageantialias — Should antialias functions be used or not

Descripción

bool imageantialias ( resource $image , 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.

Lista de parámetros

image: An image resource, returned by one of the image creation functions, such as imagecreatetruecolor().
on: Whether to enable antialiasing or not.

Valores retornados

Devuelve TRUE si todo se llevó a cabo correctamente, FALSE en caso de fallo.

Notes

Note: Esta funcion esta disponible solamente si PHP se ha compilado con la version de las bibliotecas GD distribuidas con PHP.
