API, Reference Guides
Overview of external readers and the Altair Binary Format, the generic ASCII reader, running applications in batch mode, using Tcl/Tk commands, translators, and result math.
- Extensions
  Extensions are programs integrated with the application to enhance or extend the user experience.
- External Readers and Altair Binary Format
  Altair Binary Format (ABF) is the standard binary format read by the program. A library called abflib allows you to create files in ABF.
- Generic ASCII Reader
  A generic ASCII reader is now available which allows you to bring custom results directly into HyperView. The Altair ASCII format is useful for reading the results of any in-house or propriety codes which are saved in a generic format.
- Batch Mode
  Batch mode allows you perform a series of operations outside the program interface.
- External Resources
  External resources can be registered in preference files, session files, or Templex files. If an external resource is registered in a program session, it is automatically registered in the session file when the session is saved.

  The Python API documentation for HyperMesh applications.
- Tcl/Tk Commands
  The application's scripting interface is a set of Tcl/Tk commands that follow a simple and consistent syntax.
  - Program with APIs for Beginners
    APIs can be used to perform various actions in an application. For example, the AddPage API can be used to add a page within the project.

hwIAMFExportOptions GetEncoder

Gets the type of encoding used when exporting AMF video files.

Syntax

hwIAMFExportOptions_handle GetEncoder

Application

HyperView Tcl Query

Description

This command retrieves the type of encoding used when exporting AMF video files:

"jpeg": AMF video frames are compressed as JPEGs. This encoding uses the quality setting returned by the hwIAMFExportOptions GetQuality function. This type of encoding can produce a smaller video file than ZLIB encoding, but it is not lossless.
"zlib": AMF video frames are compressed by ZLIB. This type of encoding is lossless, but tends to produce a larger video file than JPEG encoding.
Note: This parameter is used when exporting AMF files from any client during video capture.

Example

To determine the current encoder used when exporting AMF files:

hwi GetSessionHandle mySessionName
mySessionName GetAMFExportOptionsHandle myAmfOptions
myAmfOptions GetEncoder

Error

Returns the type of encoder used when exporting AMF files, otherwise 0 if an error occurs.
