Class STSample
Extends STTransformRaster
Given an input raster and an output raster, samples the input raster into
the output raster. This supports the following:
- Cropping an existing raster (same pixel ref dimensions, different bounds)
- Sample/scale and existing raster
Bounds:
- Specified in "TheBounds"
- In OutputRaster
Width and Height in Pixels
- OutputRaster (already allocated)
- Bounds and InputRaster's resolution
The bounds to copy can be specified either in the OutputRaster
or a local property. If a local property is used, the copy may be a subset of the outputRaster,
otherwise, the entire raster output area will try to be copied.
The width and height in pixels of the OutputRaster may be specified in the OutputRaster.
If the OutputRaster has a WIdthInPixels of zero, the output pixel dimensions will
be computed from the available bounds and the Input raster's pixel resolution.
