Descrierea

imagexbm ( resource $image , mixed $filename [, int $foreground ] ) : bool

Outputs or save an XBM version of the given image.

Notă: imagexbm() doesn't apply any padding, so the image width has to be a multiple of 8. This restriction does no longer apply as of PHP 7.0.9.

Parametri

image

O resursă - imagine, întoarsă de una din funcțiile de creare a imaginilor, cum ar fi imagecreatetruecolor().

filename

The path to save the file to, given as string. If null, the raw image stream will be output directly.

The filename (without the .xbm extension) is also used for the C identifiers of the XBM, whereby non alphanumeric characters of the current locale are substituted by underscores. If filename is set to null, image is used to build the C identifiers.

foreground

You can set the foreground color with this parameter by setting an identifier obtained from imagecolorallocate(). The default foreground color is black. All other colors are treated as background.

Valorile întoarse
