IC Imaging Control .NET

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.
