## **Examples**
### This example demonstrates the use of different classes from `imageoptions` package for export purposes. A gif image is loaded as an instance of Image and then exported out to several formats. {#example_15}
``` python

from aspose.imaging import Image
from aspose.imaging.imageoptions import BmpOptions, JpegOptions, PngOptions, TiffOptions
from aspose.imaging.fileformats.tiff.enums import TiffExpectedFormat
from os.path import join as path_join

directory = "c:\\temp\\"
#Load an existing gif image as an instance of Image class
with Image.load(path_join(directory, "sample.gif")) as image:
	# Export to BMP file format using the default options
	image.save(path_join(directory, "output.bmp"), BmpOptions())
	# Export to JPEG file format using the default options
	image.save(path_join(directory, "output.jpg"), JpegOptions())
	# Export to PNG file format using the default options
	image.save(path_join(directory, "output.png"), PngOptions())
	# Export to TIFF file format using the default options
	image.save(path_join(directory, "output.tif"), TiffOptions(TiffExpectedFormat.DEFAULT))
