radius: the radius of the Gaussian, in pixels, not counting the center pixel.
sigma: the standard deviation of the Gaussian, in pixels.
amount: the percentage of the difference between the original and the blur image that is added back into the original.
threshold: the threshold in pixels needed to apply the diffence amount.

GM16ImageMBS.ZPL(Header as boolean = true) as String

This is for sending data to a receipt printer. The picture is taken as black & white image and we build the hex string, you can send to the printer.
Picture needs to have a width dividable by 8.

Set Header to false for skipping header and footer.
