image2wbmp — Output image to browser or file
image2wbmp() is deprecated as of PHP 7.3.0, and will be removed in the next major version. Use imagewbmp() instead.
$image
[, string $filename
[, int $foreground
]] )
image2wbmp() outputs or save a WBMP
version of the given image.
imageAn image resource, returned by one of the image creation functions, such as imagecreatetruecolor().
filenamePath to the saved file. If not given, the raw image stream will be output directly.
foregroundYou can set the foreground color with this parameter by setting an identifier obtained from imagecolorallocate(). The default foreground color is black.
Returns TRUE on success or FALSE on failure.
However, if libgd fails to output the image, this function returns TRUE.

$image = imagecreatefrompng($file);
header('Content-Type: ' . image_type_to_mime_type(IMAGETYPE_WBMP));
