(PHP 5, PHP 7)
imagexbm — Output an XBM image to browser or file
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.
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.
