(PHP 5, PHP 7)
imagexbm — Output an XBM image to browser or file
$image
, string $filename
[, int $foreground
] )
Outputs or save an XBM version of the given
image.
Nota: 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.
imageUm resource de imagem, retornado por funções de criação de imagens, como imagecreatetruecolor().
filenameThe 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.
foregroundYou 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.
Retorna TRUE em caso de sucesso ou FALSE em caso de falha.
Exemplo #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);
?>
Exemplo #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);
