mirror_region(Region : RegionMirror : Mode, WidthHeight : )

描述

mirror_regionmirror_regionMirrorRegionMirrorRegionMirrorRegionmirror_region reflects a region about one of three possible axes. If ModeModeModeModemodemode is set to 'row'"row""row""row""row""row", it is reflected about the horizontal axis, if ModeModeModeModemodemode is set to 'column'"column""column""column""column""column", about the vertical axis, and if ModeModeModeModemodemode is set to 'diagonal'"diagonal""diagonal""diagonal""diagonal""diagonal", about the main diagonal x=y.

For ModeModeModeModemodemode = 'row'"row""row""row""row""row" or 'column'"column""column""column""column""column" the parameter WidthHeightWidthHeightWidthHeightWidthHeightwidthHeightwidth_height specifies two times the coordinate of the axis of symmetry. Hence, if RegionRegionRegionRegionregionregion has been extracted from an image and should be mirrored in a way such as if it had been extracted from a mirrored version of this image, WidthHeightWidthHeightWidthHeightWidthHeightwidthHeightwidth_height corresponds to one of the dimensions of this image (according to ModeModeModeModemodemode). If ModeModeModeModemodemode = 'diagonal'"diagonal""diagonal""diagonal""diagonal""diagonal", the parameter WidthHeightWidthHeightWidthHeightWidthHeightwidthHeightwidth_height is not used.
