Return each coordinate of the UDO rectangle (this is exactly the area you may paint in).
The properties are only accessible while you are processing the event DoUDOPaint() (VCL: OnUDOPaint(), .NET: UDOPaint()). Retrieving the values while not processing the event will return invalid - and therefore useless - data.
property VpeCoord VPE.nUDOLeft
property VpeCoord VPE.nUDOTop
property VpeCoord VPE.nUDORight
property VpeCoord VPE.nUDOBottom
read; runtime only
Returns:
the coordinates of the UDO which fired the currently processed UDO-Paint-Event
Remarks:
In contrast to the other n-Properties the nUDO-Properties return the bounding rectangle of the UDO in DEVICE COORDINATES (!) (pixels, not metric units). Therefore, independently from the resolution of the output device or the scaling factor of the preview, the coordinates are computed by VPE accordingly. Be it the 96 DPI screen, a 200 DPI fax, a 600 DPI printer or a 300 DPI export image (yes, UDO works with PictureExport, too!).
