imagecolortransparent - Define a color as transparent

SYNOPSIS
int imagecolortransparent (resource $image, [int $color]) DESCRIPTION
Sets the transparent color in the given $image. PARAMETERS
o $ image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3). o $color - A color identifier created with imagecolorallocate(3). RETURN VALUES
The identifier of the new (or current, if none is specified) transparent color is returned. If $color is not specified, and the image has no transparent color, the returned identifier will be -1. EXAMPLES
Example #1 imagecolortransparent(3) example <?php // Create a 55x30 image $im = imagecreatetruecolor(55, 30); $red = imagecolorallocate($im, 255, 0, 0); $black = imagecolorallocate($im, 0, 0, 0); // Make the background transparent imagecolortransparent($im, $black); // Draw a red rectangle imagefilledrectangle($im, 4, 4, 50, 25, $red); // Save the image imagepng($im, './imagecolortransparent.png'); imagedestroy($im); ?> The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : imagecolortransparent() NOTES
Note Transparency is copied only with imagecopymerge(3) and true color images, not with imagecopy(3) or pallete images. Note The transparent color is a property of the image, transparency is not a property of the color. Once you have set a color to be the transparent color, any regions of the image in that color that were drawn previously will be transparent. PHP Documentation Group IMAGECOLORTRANSPARENT(3)
