imagexbm

(PHP 5, PHP 7)

imagexbm — Output an XBM image to browser or file

Beschreibung

imagexbm ( resource $image [, string $filename = NULL [, int $foreground ]] ) : bool

Outputs or save an XBM version of the given image.

Hinweis: 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 5.6.24 and 7.0.9, respectively.

Parameter-Liste

image

Eine von den verschiedenen Erzeugungsfunktionen wie imagecreatetruecolor() gelieferte Grafikressource.

filename

The path to save the file to. If not set or NULL, the raw image stream will be outputted 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.

Rückgabewerte

Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.

Achtung

However, if libgd fails to output the image, this function returns TRUE.
