# 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:

範例 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;
}
?>`

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

> 提示: 如果 fopen wrappers 已啟動，則可藉此函數把檔名當成URL使用。參考 fopen() 有更多關於如何指定檔名的細節和附錄 L支援URL協定的列表。

警告
PHP 4.3.0 之前的 Windows PHP版本不支援由此函數存取遠端檔案，即使啟動allow_url_fopen選項。
