poIImagePlane SetStretchToFit

Sets an image plane in the background or foreground mode to a predefined window location.

Syntax

Imageplane_handle SetStretchToFitval

Application

HyperView Tcl Modify

Description

When an image plane is in background or foreground mode, setting the StretchToFit flag to true will cause the image or video to be stretched to consume the entire HyperMesh window when drawn. This command modifies this flag.

Inputs

val: True or False to indicate whether to stretch the image (or not).

Example

To create two image planes, then set the stretch-to-fit flag (and other basic properties) on one of them:

Returns HW_InvalidHandle if the image plane handle is invalid.
