Create a new image from file or URL (PHP 4, PHP 5)
resource imagecreatefrompng ( string filename )

imagecreatefrompng() returns an image identifier representing the image obtained from the given filename.

imagecreatefrompng() returns an empty string on failure. It also outputs an error message, which unfortunately displays as a broken link in a browser. To ease debugging the following example will produce an error PNG:

Example 1002. Example to handle an error during creation

function LoadPNG($imgname)
$im = @imagecreatefrompng($imgname); /* Attempt to open */
if (!$im) { /* See if it failed */
$im  = imagecreatetruecolor(150, 30); /* Create a blank image */
$bgc = imagecolorallocate($im, 255, 255, 255);
$tc  = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 150, 30, $bgc);
/* Output an errmsg */
imagestring($im, 1, 5, 5, "Error loading $imgname", $tc);
header("Content-Type: image/png");
$img = LoadPNG("bogus.image");

The above example will output something similar to:


You can use a URL as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename and Appendix O, List of Supported Protocols/Wrappers for a list of supported URL protocols.



Path to the PNG image

Return Values

Windows versions of PHP prior to PHP 4.3.0 do not support accessing remote files via this function, even if allow_url_fopen is enabled.
