RasterLayer

RasterLayer class

Represents a raster layer.

public abstract class RasterLayer : IDisposable

Properties

Name Description
abstract BandCount { get; } Gets the number of bands in the raster layer.
Bounds { get; } Gets the raster bounds.
abstract CellSize { get; } Gets cell or pixel size of the raster.
abstract Driver { get; } Gets the Driver that instantiated this layer.
abstract Height { get; } Gets the height of the raster in pixels. Also it is known as rows count.
abstract NoDataValues { get; } Gets the values that represents background or ’no data’ of the raster.
abstract SpatialReferenceSystem { get; } Gets a spatial reference system of raster. Can be null if it is unknown.
abstract UpperLeftX { get; } Gets x-coordinate of the raster upper left corner.
abstract UpperLeftY { get; } Gets y-coordinate of the raster upper left corner.
abstract Width { get; } Gets the width of the raster in pixels. Also it is known as columns count.
