IMAGECREATEFROMPNG(3) 1 IMAGECREATEFROMPNG(3)imagecreatefrompng - Create a new image from file or URLSYNOPSIS
resource imagecreatefrompng (string $filename)
DESCRIPTION imagecreatefrompng(3) returns an image identifier representing the image obtained from the given filename.
Tip
A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen(3) for more details on how to
specify the filename. See the "Supported Protocols and Wrappers" for links to information about what abilities the various wrappers
have, notes on their usage, and information on any predefined variables they may provide.
PARAMETERS
o $filename
- Path to the PNG image.
RETURN VALUES
Returns an image resource identifier on success, FALSE on errors.
EXAMPLES
Example #1
Example to handle an error during loading of a PNG
<?php
function LoadPNG($imgname)
{
/* Attempt to open */
$im = @imagecreatefrompng($imgname);
/* See if it failed */
if(!$im)
{
/* Create a blank image */
$im = imagecreatetruecolor(150, 30);
$bgc = imagecolorallocate($im, 255, 255, 255);
$tc = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 150, 30, $bgc);
/* Output an error message */
imagestring($im, 1, 5, 5, 'Error loading ' . $imgname, $tc);
}
return $im;
}
header('Content-Type: image/png');
$img = LoadPNG('bogus.image');
imagepng($img);
imagedestroy($img);
?>
The above example will output something similar to:[NOT DISPLAYABLE MEDIA]imagecreatefrompng() example
