imagexbm
(PHP 5, PHP 7, PHP 8)
imagexbm — Output an XBM image to browser or file
Description
Outputs or save an XBM version of the given
image.
Note: 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.
Parameters
-
image -
A GdImage object, returned by one of the image creation functions, such as 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. Iffilenameis set tonull,imageis used to build the C identifiers. -
foreground_color -
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.
Return Values
Returns true on success or false on failure.
Caution
However, if libgd fails to output the image, this function returns true.
Changelog
| Version | Description |
|---|---|
| 8.0.0 |
image expects a GdImage
instance now; previously, a valid gd resource was expected.
|
| 8.0.0 |
foreground_color is now nullable.
|
| 8.0.0 | The fourth parameter, which was unused, has been removed. |
Examples
Example #1 Saving an XBM file
<?php
// Create a blank image and add some text
$im = imagecreatetruecolor(120, 20);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color);
// Save the image
imagexbm($im, 'simpletext.xbm');
// Free up memory
imagedestroy($im);
?>
Example #2 Saving an XBM file with a different foreground color
<?php
// Create a blank image and add some text
$im = imagecreatetruecolor(120, 20);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color);
// Set a replacement foreground color
$foreground_color = imagecolorallocate($im, 255, 0, 0);
// Save the image
imagexbm($im, NULL, $foreground_color);
// Free up memory
imagedestroy($im);
