TiffOptions Class

Summary: The tiff file format options.
Note that width and height tags will get overwritten on image creation by width and height parameters so there is no need to specify them directly.
Note that many options return a default value but that does not mean that this option is set explicitly as a tag value. To verify the tag is present use Tags property or the corresponding IsTagPresent method.

Examples

This examples make use of GraphicsPath and Graphics classes to create and manipulate figures on an Image surface. Example creates a new Image (of type Tiff), clears the surface and draws paths with the help of GraphicsPath class. At the end `draw_path` method exposed by Graphics class is called to render the paths on surface.


from aspose.imaging import Image, Graphics, Color, GraphicsPath, Figure, RectangleF, PointF, SizeF
from aspose.imaging import Pen
from aspose.imaging.sources import StreamSource
from aspose.imaging.imageoptions import TiffOptions
from aspose.imaging.fileformats.tiff.enums import TiffExpectedFormat
from aspose.imaging.shapes import RectangleShape, EllipseShape, PieShape


# Create an instance of a file stream
with open(r"C:\temp\output.tiff", "w+b") as stream:
	# Create an instance of TiffOptions and set its various properties
	tiffOptions = TiffOptions(TiffExpectedFormat.DEFAULT)
	# Set the source for the instance of ImageOptions
	tiffOptions.source = StreamSource(stream)
	# Create an instance of Image
	with Image.create(tiffOptions, 500, 500) as image:
		# Create and initialize an instance of Graphics class
		graphics = Graphics(image)
		# Clear Graphics surface
		graphics.clear(Color.wheat);
		# Create an instance of GraphicsPath class
		graphics_path = GraphicsPath()
		# Create an instance of Figure class
		figure = Figure()
		# Add Shapes to Figure object
		figure.add_shape(RectangleShape(RectangleF(10.0, 10.0, 300.0, 300.0)))
		figure.add_shape(EllipseShape(RectangleF(50.0, 50.0, 300.0, 300.0)))
		figure.add_shape(PieShape(RectangleF(PointF(250.0, 250.0), SizeF(200.0, 200.0)), 0.0, 45.0))
		# Add Figure object to GraphicsPath
		graphics_path.add_figure(figure)
		# Draw path with Pen object of color Black
		graphics.draw_path(Pen(Color.black, 2.0), graphics_path)
		# save all changes.
		image.save()

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.


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))
