IMcRegionAccessLinesBelow Property

Property Value

Type: Int32

The LinesAbove (smaller Y) and LinesBelow (larger Y) properties are only relevant in-process if you call the GetLinePointer method. These properties specify a range of lines (of the McRegionAccess Width) that are guaranteed to be at the same memory address they were at the last GetLinePointer call. Note that you will need to access lines above and below by offsetting the memory address by the McPixelPointer.RowStride. Never assume that the pointer returned by one GetLinePointer method call is still valid after a second such call. By default LinesAbove is the full height of the ROI, so the entire region access area is always locked when GetLinePointer is called for any line.
