Examples

The following example shows how to retrieve paths from TIFF image and display their names in the console.


from aspose.pycore import as_of
from aspose.imaging import Image
from aspose.imaging.fileformats.tiff import TiffImage

with as_of(Image.load("Sample.tif"), TiffImage) as image:
	for path in image.active_frame.path_resources:
		print(path.name)

The following example shows how to modify already existing Clipping Paths. For instance, you can keep only one Clipping Path in the image.


from aspose.pycore import as_of
from aspose.imaging import Image
from aspose.imaging.fileformats.tiff import TiffImage

with as_of(Image.load("Sample.tif"), TiffImage) as image:
	frame = image.active_frame
	paths = frame.path_resources
	frame.path_resources = paths[0:1]
	image.save()

Transfer Clipping Paths during export from TIFF to PSD image.


from aspose.imaging import Image
from aspose.imaging.imageoptions import PsdOptions

with Image.load("Sample.tif") as image:
	image.save("SampleWithPaths.psd", PsdOptions())
