Showing

Call the getResult() method to get a variable containing the merged image of your document (previous page):

$image = $layer->getResult();

Then, use the classical php functions to show an image:

1 - Showing a PNG
header('Content-type: image/png');
header('Content-Disposition: filename="butterfly.png"');
imagepng($image, null, 8); // We choose to show a PNG (quality of 8 on a scale of 0 to 9)
exit;
2 - Showing a JPEG
header('Content-type: image/jpeg');
header('Content-Disposition: filename="butterfly.jpg"');
imagejpeg($image, null, 95); // We choose to show a JPEG (quality of 95%)
exit;
3 - Showing a GIF
header('Content-type: image/gif');
header('Content-Disposition: filename="butterfly.gif"');
imagegif($image); // We choose to show a GIF
exit;



Don't forget to give a background color when you want to show a JPEG or GIF when calling getResult() (see the previous page): 

$image = $layer->getResult("ffffff"); // white background

You can also save an image with native php functions imagexxx() but ImageWorkshop provides a magic save() function.
