How to add signature to image

Issue : How to add signature to image.

Tips : To add signature to image, it is needed to use Graphics class and function DrawImage.

Example :

	import aspose.pycore as aspycore
	from aspose.imaging import Image, Graphics, Point
	from aspose.imaging.imageoptions import PngOptions
	import os

	if 'TEMPLATE_DIR' in os.environ:
	templates_folder = os.environ['TEMPLATE_DIR']
	else:
	templates_folder = r"C:\Users\USER\Downloads\templates"

	delete_output = 'SAVE_OUTPUT' not in os.environ

	data_dir = templates_folder
	# Create an instance of Image and load the primary image
	with Image.load(os.path.join(data_dir, "template.tiff")) as canvas:
	# Create another instance of Image and load the secondary image containing the signature graphics
	with Image.load(os.path.join(data_dir, "template.jpg")) as signature:
	# Create an instance of Graphics class and initialize it using the object of the primary image
	graphics = Graphics(canvas)
	# Call the DrawImage method while passing the instance of secondary image and appropriate location. The following snippet tries to draw the secondary image at the right bottom of the primary image
	graphics.draw_image(signature, Point(canvas.width - signature.width, canvas.height - signature.height))
	canvas.save(os.path.join(data_dir, "result.png"), PngOptions())

	if delete_output:
	os.remove(os.path.join(data_dir, "result.png"))
