interface ICanvasTransform in Tinman.Terrain.Georef

Base interface for classes that transform coordinates between a map raster (defined by Map and Georef) and a two-dimensional canvas (defined by a Coordinates).

interface	ICanvasTransform	extends	IGeorefInfo
		base of	TerrainDecal

Attributes

Coordinates

The coordinate system of the canvas.

property	Coordinates { get }
type	CoordinateSystem
value		The canvas coordinate system or null if canvas space cannot be described by a CoordinateSystem object (e.g. an unfolded cubemap).

Georef

Returns georeferencing information.

property	Georef { get }
type	Raster
value		The georeferencing object or null if no georeferencing is available.
inherited	IGeorefInfo.Georef

Map

Returns a MapInfo value that describes the used map raster.

property	Map { get }
type	MapInfo
value		The map info value.
inherited	IMapInfo.Map

Methods

CanvasToMapRaster

Transforms the given canvas coordinates into map raster coordinates.

method	CanvasToMapRaster (float64 x, float64 y, bool maxSize = false)
type	Vec3D
params	x		X-component of input canvas coordinates.
	y		Y-component of input canvas coordinates.
	maxSize		Return map raster coordinates for MaxSize, instead of Size of Map? Defaults to false.
returns			The output map raster coordinates (see Georef and Map resp. maxSize), or Undefined if the transformation is not possible.

MapRasterToCanvas

Transforms the given map raster coordinates into canvas coordinates.

method	MapRasterToCanvas (float64 x, float64 y, float64 z = 0, bool maxSize = false)
type	Vec2D
params	x		X-component of input map raster coordinates.
	y		X-component of input map raster coordinates.
	z		X-component of input map raster coordinates. Defaults to 0.
	maxSize		Are input map raster coordinates specified for MaxSize, instead of Size of Map? Defaults to false.
returns			The output canvas coordinates (see Coordinates), or Undefined if the transformation is not possible.
