ImageGear Filter Control Parameters

Filter Control Parameter Type Default Value Available Values Description
ResolutionX int 96 Any integer This parameter specifies the horizontal resolution, in dots-per-inch, during the XPS document conversion into a raster image. The greater this value, the higher the quality of the raster image after rasterization. The DIB of the output raster image has this value as an X resolution.
ResolutionY int 96 Any integer This parameter specifies the vertical resolution, in dots-per-inch, during the XPS document conversion into a raster image. The greater this value, the higher the quality of the raster image after rasterization. The DIB of the output raster image has this value as an Y resolution.

Non-Image Data Structure

The XML Paper Specification file format has different nonimage data that can be stored in a package as XML or as resources. The XML Paper Specification metadata design allows reading and writing the following nonimage data (the same as in System.IO.Packaging.PackageProperties ; all are strings):

Tag Name Tag ID Description
Category ImGearXPSTagIDs.CATEGORY The category of the content that is contained in the file.
ContentStatus ImGearXPSTagIDs.CONTENT_STATUS Example ContentStatus values include "Draft", "Reviewed", and "Final".
ContentType ImGearXPSTagIDs.CONTENT_TYPE Example ContentType values include "Whitepaper", "Security Bulletin", and "Exam".
Created ImGearXPSTagIDs.CREATED The date and time the file was initially created.
Creator ImGearXPSTagIDs.CREATOR The individual or entity that created the file and its content.
Description ImGearXPSTagIDs.DESCRIPTION The Description may include, but is not limited to: an abstract, table of contents, reference to a graphical representation of content, or a free-text account of the content.
Identifier ImGearXPSTagIDs.IDENTIFIER A value that unambiguously identifies the file and its content.
Keywords ImGearXPSTagIDs.KEYWORDS A delimited set of keywords to support searching and indexing the Package and content.The Keywords property typically contains a list of terms that are not available elsewhere in file metadata.
Language ImGearXPSTagIDs.LANGUAGE A value that identifies the file content language.
LastModifiedBy ImGearXPSTagIDs.LAST_MODIFIED_BY The user who last modified the file content.
LastPrinted ImGearXPSTagIDs.LAST_PRINTED The date and time the file content was last printed.
Modified ImGearXPSTagIDs.MODIFIED The date and time the file was last changed.
Revision ImGearXPSTagIDs.REVISION The revision number of the file. The Revision property indicates the number of changed saves or revisions. The application is responsible for updating the Revision property value after each revision.
Subject ImGearXPSTagIDs.SUBJECT The topic of the file content.
Title ImGearXPSTagIDs.TITLE The name given to the file and its content.
Version ImGearXPSTagIDs.VERSION The version number of the file.

Comments

The XPS Document format represents a set of related pages with a fixed layout, which are organized as one or more documents, in the traditional meaning of the word. A file that implements this format includes everything necessary to fully render those documents on a display device or physical medium (for example, paper). This includes all resources, such as fonts and images, that might be required to render individual page markings.

In addition, the format includes optional components that build on the minimal set of components required to render a set of pages. This includes the ability to specify print job control instructions, to organize the minimal page markings into larger semantic blocks, such as paragraphs, and to physically rearrange the contents of the format for easy consumption in a streaming manner, among others.

The XPS format supports HD Photo images natively for raster images.

The XPS format concept is similar to Adobe PDF. It is a fixed-layout document format designed to preserve document fidelity, so that documents look the same and as they are intended on any device. While Adobe PDF is based on PostScript the XPS format is based on XML. Adobe PDF, however, includes some dynamic capabilities not supported by the XPS format, and cannot be fully replaced by XPS.

Finally, the XPS Document format implements the common package features, specified by the Open Packaging Conventions specification, that support digital signatures and core properties. An XPS file is a ZIP archive conforming to the Open Packaging Convention.

The XPS format is intended as the replacement for the EMF print spooler format. The format serves as the page description language for printers. For printers supporting XPS, this eliminates an intermediate conversion to a printer-specific language, increasing the reliability and fidelity of the printed output.
