ReprojectionOptionsBlockSize Property |
The block size (width/height) for which linear interpolation applies.
Namespace: Ptv.XServer.Controls.Map.Tools.Reprojection
Assembly: Ptv.XServer.Controls.Map (in Ptv.XServer.Controls.Map.dll) Version: 1.7.10.0
SyntaxRemarks
Defaults to 32.
Mapping target to source pixels is considered an expensive operation requiring multiple transformations on both, pixel and logical coordinates. Being expensive, re-projection uses this mapping only to calculate a grid consisting of supporting points, while applying a linear interpolation for intermediate points (point withing a grid block). The parameter blockSize determines both width and height of a single cell.
