CodecsXpsSaveOptions Class

Summary

Provides the options for saving a raster image as an Open XML Paper Specification (XPS) document.

Syntax

C++/CLI

Java

Python

public class CodecsXpsSaveOptions

public class CodecsXpsSaveOptions

public ref class CodecsXpsSaveOptions

class CodecsXpsSaveOptions:

Remarks

The Open XML Paper Specification Format supports saving images with either PNG or JPEG Compression.

The following table shows the quality factor used when an image is saved with a particular format:

Format	Property
RasterImageFormat.Xps	CodecsXpsSaveOptions.PngQualityFactor
RasterImageFormat.XpsJpeg	CodecsXpsSaveOptions.JpegQualityFactor
RasterImageFormat.XpsJpeg422	CodecsXpsSaveOptions.JpegQualityFactor
RasterImageFormat.XpsJpeg411	CodecsXpsSaveOptions.JpegQualityFactor
