Usage Examples:

IMAGINGPYTHONNET-292 MemoryStream ObjectDisposedException saving Tiff

from aspose.imaging import Image
from aspose.imaging.imageoptions import TiffOptions
from aspose.imaging.sources import StreamSource
from aspose.imaging.extensions import StreamExtensions as streams
from aspose.imaging.fileformats.tiff.enums import TiffExpectedFormat


def save_tiff(stream):
    tiffOptions = TiffOptions(TiffExpectedFormat.TIFF_LZW_RGBA)
	tiffOptions.source = StreamSource(stream)
	with Image.create(tiffOptions, 1000, 1000) as image:
        image.save()

    # does not throw exception
    print(stream.tell())

def tiff_test():
    with streams.create_memory_stream() as ms:
		save_tiff(ms)
		gc.collect(0)
		# does not throw exception
		print(ms.tell())

tiff_test()

IMAGINGPYTHONNET-291 Incorrectly closed path on SVG render

### Example
The sample SVG is exported as an image with an open arc without crossed lines.

from aspose.imaging import Image
from aspose.imaging.imageoptions import SvgRasterizationOptions, PngOptions

inputFilePath = "svgHalfNotch2.svg"
outputFilePath = "svgHalfNotch2.svg.png"
with Image.load(inputFilePath) as image:
	rasterizationOptions = SvgRasterizationOptions()
	rasterizationOptions.page_width = image.width
	rasterizationOptions.page_height = image.height
	pngOptions = PngOptions()
	pngOptions.vector_rasterization_options = rasterizationOptions

	image.save(outputFilePath, pngOptions)

IMAGINGPYTHONNET-287 Fix EMF to SVG error, extend SVG gradient support

from aspose.imaging import Image
input_file = "input.emf";
with Image.load(input_file) as image:
	image.save(input_file + ".svg")

IMAGINGPYTHONNET-283 Incorrect export from particular EMF to any raster format in memory optimization strategy

from aspose.imaging import Image, LoadOptions
from aspose.imaging.imageoptions import PngOptions, JpegOptions, BmpOptions

load_options = LoadOptions()
load_options.buffer_size_hint = 200
with Image.load("1.emf", load_options) as image:
    image.save("output.png", PngOptions())

with Image.load("1.emf", load_options) as image:
    image.save("output.jpg", JpegOptions())

with Image.load("1.emf", load_options) as image:
    image.save("output.bmp", BmpOptions())
