How to save jpeg image with various compression types

Issue : How to save jpeg image with various compression types.

Tips : To properly save jpeg image with various compression types, it is needed to set compression type in JpegOptions.

Example :

	import aspose.pycore as aspycore
	from aspose.imaging import Image
	from aspose.imaging.fileformats.jpeg import JpegCompressionMode, JpegCompressionColorMode, JpegLsInterleaveMode
	from aspose.imaging.imageoptions import JpegOptions
	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
	with Image.load(os.path.join(data_dir, "template.jpg")) as image:
	# JpegLs
	obj_init = JpegOptions()
	obj_init.compression_type = JpegCompressionMode.JPEG_LS
	obj_init.color_type = JpegCompressionColorMode.GRAYSCALE
	obj_init.jpeg_ls_interleave_mode = JpegLsInterleaveMode.NONE
	options_jpeg_ls = obj_init
	image.save(os.path.join(data_dir, "result.jpg"), options_jpeg_ls)
	# Lossless
	obj_init2 = JpegOptions()
	obj_init2.compression_type = JpegCompressionMode.LOSSLESS
	obj_init2.color_type = JpegCompressionColorMode.GRAYSCALE
	options_lossless = obj_init2
	image.save(os.path.join(data_dir, "result2.jpg"), options_lossless)

	if delete_output:
	os.remove(os.path.join(data_dir, "result.jpg"))
	os.remove(os.path.join(data_dir, "result2.jpg"))
