(PHP 4 >= 4.0.1)

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:

Ejemplo 1. Example to handle an error during creation (courtesy vic@zymsys.com)

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;
}

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

Sugerencia: Puede usar una URL como nombre de archivo con esta función si los "fopen wrappers" han sido activados. Consulte fopen() para más detalles.

Aviso

La versión actual de PHP para Windows, no soporta el acceso remoto a ficheros en esta función, no funcionará incluso activando allow_url_fopen.
