imagecreatefromwbmp

Create a new image from file or URL (PHP 4 >= 4.0.1)
resource imagecreatefromwbmp ( string filename )

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

imagecreatefromwbmp() 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 WBMP:

Example 416. Example to handle an error during creation (courtesy vic at zymsys dot com)

<?php
function LoadWBMP ($imgname) {
   
$im = @imagecreatefromwbmp ($imgname); /* Attempt to open */
   
if (!$im) { /* See if it failed */
       
$im  = imagecreate (20, 20); /* Create a blank image */
       
$bgc = imagecolorallocate ($im, 255, 255, 255);
       
$tc  = imagecolorallocate ($im, 0, 0, 0);
       
imagefilledrectangle ($im, 0, 0, 10, 10, $bgc);
       
/* Output an errmsg */
       
imagestring ($im, 1, 5, 5, "Error loading $imgname", $tc);
   }
   return
$im;
}
?>
Note:

WBMP support is only available if PHP was compiled against GD-1.8 or later.

Tip:

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 I for a list of supported URL protocols.

Warning:

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.
