@param metaData Properly initialized CallMetaData struct, i.e. information about file, line and
function name for GUI. Use CVVISUAL_LOCATION macro.
@param description Human readable description to provide context to image.
@param view Preselect view that will be used to visualize this image in GUI. Other views can still
be selected in GUI later on.
