Class Map<TColor, TDepth>
A Map is similar to an Image, except that the location of the pixels is defined by its area and resolution
public class Map<TColor, TDepth> : Image<TColor, TDepth>, IXmlSerializable, ISerializable, IEquatable<Image<TColor, TDepth>>, IInputOutputArray, IInputArrayOfArrays, IOutputArrayOfArrays, IOutputArray, IInputArray, IDisposable where TColor : struct, IColor where TDepth : new()Type Parameters
TColorThe color of this map
TDepthThe depth of this map

Map(RectangleF, PointF)
Create a new Image Map defined by the Rectangle area. The center (0.0, 0.0) of this map is defined by the center of the rectangle. The initial value of the map is 0.0
public Map(RectangleF area, PointF resolution)Parameters
areaRectangleFThe area this map covers.
resolutionPointFThe resolution of x (y), (e.g. a value of 0.5 means each cell in the map is 0.5 unit in x (y) dimension)
Map(RectangleF, PointF, TColor)

areaRectangleFThe area this map covers.
resolutionPointFThe resolution of x (y), (e.g. a value of 0.5 means each cell in the map is 0.5 unit in x (y) dimension)
colorTColorThe initial color of the map
