imagecreatefromwbmp

(PHP 4 >= 4.0.1, PHP 5)

imagecreatefromwbmp -- Create a new image from file or URL

Description

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 1. Example to handle an error during creation

<?php
function LoadWBMP($imgname)
{
    
$im = @imagecreatefromwbmp($imgname); /* Attempt to open */
    
if (!$im) { /* See if it failed */
        
$im  = imagecreatetruecolor (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 M 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.
