名称
mirror_regionmirror_regionMirrorRegionMirrorRegionmirror_region — Reflect a region about an axis.
参数签名
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 区域区域区域区域区域区域 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.
运行信息
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
