Description

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

Example 1. 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 L 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.

WBMP images are Wireless Bitmaps, not Windows Bitmaps. WBMP is used for bandwidth constrained, black and white, limited devices such as PDAs and Cell Phones.
