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())
