Usage Examples:

IMAGINGPYTHONNET-500 Incorrect colors on specific Tiff to Png conversion

from aspose.imaging import Image
from aspose.imaging.imageoptions import PngOptions
from aspose.imaging.fileformats.png import PngColorType

inputPath = "input.tiff"
with Image.load(inputPath) as image:
	png_options = PngOptions()
	png_options.color_type = PngColorType.TRUECOLOR_WITH_ALPHA
	image.save(inputPath + ".png", png_options)

IMAGINGPYTHONNET-499 Consider the possibility of parallelizing processes using the Parallel class

from aspose.pycore import as_of
from aspose.imaging import Image, RasterImage
from aspose.imaging.imagefilters.filteroptions import MedianFilterOptions
from datetime import datetime

with as_of(Image.load("test.png"), RasterImage) as image:
	start = datetime.now()
	image.filter(image.bounds, MedianFilterOptions(6))
	end = datetime.now()
	diff_seconds = (end - start).total_seconds()
	print(f"Median filter: {diff_seconds} sec")
	image.save("result.png")

Current version ~2.59 sec
Version 26.4 ~17.29 sec

*Testing was conducted on a 16-core processor.

IMAGINGPYTHONNET-498 BigTIFF: Merging ~260 single-page TIFF files into one BigTIFF leads to an exception “IOException: Stream was too long”

from aspose.imaging.fileformats.tiff.enums import TiffExpectedFormat
from aspose.imaging.fileformats.tiff import TiffFrame, TiffImage

			new_frame.cache_data()
			
			for i in range(1, new_frame_count):

			image.save()
		
		with open(output_path, 'rb') as file:
			with Image.load(file) as image:
				tiff_image = as_of(image, TiffImage)
				assert new_frame_count == tiff_image.page_count
			
			assert os.path.getsize(output_path) > 2**32 - 1
	finally:
		if os.path.exists(output_path):
			os.remove(output_path)
