IMcRegionAccessSignalImageChanged Method

Used by clients, especially the Capture Module, to inform the system that the contents of the frame have changed via processes external to the IMcImage methods.

Namespace: MediaCy.IQL.Engine
Assembly: MediaCy.IQL.Engine (in MediaCy.IQL.Engine.dll) Version: 10.0.6912.0

Syntax

Copy

Sub SignalImageChanged

Remarks

For example, the Capture Module may "own" the image buffer (see McImages::AddImageFromMemory) and used DMA to snap a video frame into the buffer. This method generates the "Image Changed" notification. Note that this event may be blocked by setting McObject.UserFlags mcobjUserFlagMinimizeProcessing bit in the AccessedImage operator's backing McObject (see McEngine.McObject).
