FrameFilterImpl.Transform Method

FrameFilterImpl.Transform Method

This method is called when a frame must be transformed or copied from the source to the destination IFrame.
Syntax:
[C#]
public bool Transform( IFrame src, IFrame dest );
Parameter Description
src

Source frame. The source frame can not be overwritten or changed.

dest

Destination frame. This frame will receive the changes. If the destination frame was changed, the method shoud return True.

Return Value:
Value Description
true The transformation was successful.
false Discard the frame.
Remarks:

The image data pointer returned by IFrame.Ptr may be null for the destination frame dest. In this case, no target for the copy operation is available, e.g. all buffers of the ImageBuffers are locked. The transform filter is called, because the implementation may need to analyze the input data.
