imageantialias
IMAGEANTIALIAS(3) 1 IMAGEANTIALIAS(3)imageantialias - Should antialias functions be used or notSYNOPSIS
bool imageantialias (resource $image, bool $enabled)
DESCRIPTION
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.
PARAMETERS
o $
image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).
o $enabled
- Whether to enable antialiasing or not.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
A comparison of two lines, one with anti-aliasing switched on
<?php
// Setup an anti-aliased image and a normal image
$aa = imagecreatetruecolor(400, 100);
$normal = imagecreatetruecolor(200, 100);
// Switch antialiasing on for one image
imageantialias($aa, true);
// Allocate colors
$red = imagecolorallocate($normal, 255, 0, 0);
$red_aa = imagecolorallocate($aa, 255, 0, 0);
// Draw two lines, one with AA enabled
imageline($normal, 0, 0, 200, 100, $red);
imageline($aa, 0, 0, 200, 100, $red_aa);
// Merge the two images side by side for output (AA: left, Normal: Right)
imagecopymerge($aa, $normal, 200, 0, 0, 0, 200, 100, 100);
// Output image
header('Content-type: image/png');
imagepng($aa);
imagedestroy($aa);
imagedestroy($normal);
?>
The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : A comparison of two lines, one with
anti-aliasing switched on
