F_VN_TransformIntoDisplayableImage

F_VN_TransformIntoDisplayableImage 1:

Transform an image into a displayable image. The source image will be released and zeroed while existing destination images will be released and overwritten with the function result. The source image must not be used anywhere else and the transformation is very fast. If you want to use ipSrcImage after this function call, use F_VN_CopyIntoDisplayableImage instead.

Notice

Use with Ads Communicator object

Note the case where the image to be transformed originates from a camera object whose Ads Communicator object is active! It may then be the case that the image is not internally released in the object and therefore cannot be transformed into a displayable image. In this case, use F_VN_CopyIntoDisplayableImage or F_VN_TransformIntoDisplayableImageExp with bAllowDeepCopy := TRUE.
