Usage Examples:

IMAGINGPYTHONNET-388 NullReferenceException: During conversion CMX in PNG and any vector image format

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

with Image.load("complex_example.cmx") as image:
   image.save("complex_example.cmx.png", PngOptions());
   image.save("complex_example.cmx.emf", EmfOptions()); # NO Exception here

IMAGINGPYTHONNET-387 Cannot open the CMX image

from aspose.imaging import Image
from aspose.imaging.imageoptions import PngOptions, CmxRasterizationOptions, PositioningTypes

with Image.load("Masjid,_Madarsa_Donation,_Raseed_Book-[1].cmx") as image:
	out_options = PngOptions()
	cmx_options = CmxRasterizationOptions()
	cmx_options.positioning = PositioningTypes.RELATIVE
	out_options.vector_rasterization_options = cmx_options
    image.save("result.png", out_options)

IMAGINGPYTHONNET-386 Cannot convert the ICO image to JPG format

Convert Ico to Jpeg:

from aspose.imaging import Image

inputPath = "input.ico"
outputPath = inputPath + ".jpg"
with Image.load(inputPath) as image:
    image.save(outputPath)

IMAGINGPYTHONNET-385 PNG CompressionLevel is not used when saving image

The following code creates 11 png files that are differently compressed.

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

with Image.load("input.png") as image:
	for compression in range(11):
		output_file = f"compressionTest{compression}.png"
		out_options = PngOptions()
		out_options.png_compression_level = PngCompressionLevel(compression)
		image.save(output_file, out_options)

IMAGINGPYTHONNET-384 Cannot convert DCM to PNG

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

lic = License()
lic.set_license("")
with Image.load("IMG00001.dcm") as image:
    image.save("IMG00001.dcm.png", PngOptions())
