Parameters
-
image -
An image resource, returned by one of the image creation functions, such as imagecreatetruecolor().
-

The path or an open stream resource (which is automatically being closed after this function returns) to save the file to. If not set or

Examples
Example #1 Outputting a WBMP image
<?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', $text_color);
// Set the content type header - in this case image/vnd.wap.wbmp
// Hint: see image_type_to_mime_type() for content-types
header('Content-Type: image/vnd.wap.wbmp');
// Output the image
imagewbmp($im);
// Free up memory
imagedestroy($im);
?>
Example #2 Saving the WBMP image
<?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', $text_color);
// Save the image
imagewbmp($im, 'simpletext.wbmp');
// Free up memory
imagedestroy($im);
?>
Example #3 Outputting the image with a different foreground
<?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 the content type header - in this case image/vnd.wap.wbmp
// Hint: see image_type_to_mime_type() for content-types
header('Content-Type: image/vnd.wap.wbmp');
// Set a replacement foreground color
$foreground_color = imagecolorallocate($im, 255, 0, 0);
imagewbmp($im, NULL, $foreground_color);
// Free up memory
imagedestroy($im);
