Examples

The example shows how to load a JpegImage from a file.

from aspose.imaging.fileformats.jpeg import JpegImage

# Load a JPEG image from a file.
with JpegImage("sample.jpg") as jpegImage:
	# Do some image processing.
	# Save to another JPEG file.
	jpegImage.save("sample.output.jpg")

The following example shows how to create JPEG image of the specified size.

from aspose.imaging.fileformats.jpeg import JpegImage

# Create a JPEG image of 100x100 px.
with JpegImage(100, 100) as jpegImage:
	# Do some image processing.
	# Save to a file.
	jpegImage.save("output.jpg")
