imagexbm
(PHP 5)
imagexbm — 将 XBM 图像输出到浏览器或文件
说明
bool imagexbm
( resource
$image
, string $filename
[, int $foreground
] )Note: 此函数仅在与 GD 库捆绑编译的 PHP 版本中可用。
参数
-
image -
由图象创建函数(例如imagecreatetruecolor())返回的图象资源。
-
filename -
文件保存的路径,如果未设置或为
NULL,将会直接输出原始图象流。 -
foreground -
You can set the foreground color with this parameter by setting an identifier obtained from imagecolorallocate(). The default foreground color is black.
返回值
成功时返回 TRUE, 或者在失败时返回 FALSE.
范例
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);
?>
