source | property |
source:BitmapData
[read-only] returns the generated bitmapdata, a smooth representation of the geometry.
public function get source():BitmapData
ElevationReader | () | Constructor |
public function ElevationReader(smoothness:int = 0)
Class generates a traced representation of the elevation geometry, allowing surface tracking to place or move objects on the elevation geometry. ElevationReader
smoothness:int (default = 0 )

applyHeightGradient | () | method |
public function applyHeightGradient(src:BitmapData, color:uint = 0x80000000, reverse:Boolean = true, blendmode:String = normal):void
Apply the generated height source to a bitmapdata. The height information is merged to the source creating a smoother look.
Parameters
src:BitmapData — The bitmapdata that will be merged.
| |
color:uint (default = 0x80000000 ) — [optional] The color that will be applied. Note that 32 bits color will allow alpha. 0x88FF0000 defines a red with .5 alpha while 0xFF0000 defines a red with no alpha. Default is .5 alpha black.
| |
reverse:Boolean (default = true ) — [optional] Defines if the color is set using the heightmap from 0-255 or 255-0. Default = true, if a black is used, the darkest are will be at the base of the elevation.
| |
blendmode:String (default = normal ) — [optional] Blendmode to be applyed in the merge. Possible string values are: lighten, multiply, overlay, screen, substract, add, darken, difference, erase, hardlight, invert and layer.Default = "normal";
|
getLevel | () | method |
public function getLevel(x:Number, y:Number, offset:Number = 0):Number
returns the generated bitmapdata, a smooth representation of the geometry.
Parameters
x:Number — The x coordinate on the generated bitmapdata.
| |
y:Number — The y coordinate on the generated bitmapdata.
| |
offset:Number (default = 0 ) — [optional] the offset that will be added to the elevation value at the x and y coordinates plus the offset. Default = 0.
|
Number — A Number, the elevation value at the x and y coordinates plus the offset.
|
setSource | () | method |
public function setSource(sourceBmd:BitmapData, channel:String = r, factorX:Number = 1, factorY:Number = 1, factorZ:Number = .5):void
Optional method to be allow the use of a custom (externally) prerendered map.
Parameters
sourceBmd:BitmapData — Bitmapdata. The bitmapData to read from.
| |
channel:String (default = r ) — [optional] String. The channel information to read. Supported "a", alpha, "r", red, "g", green, "b", blue and "av" (averages and luminance). Default is red channel "r".
| |
factorX:Number (default = 1 ) — [optional] Number. The scale multiplier along the x axis. Default is 1.
| |
factorY:Number (default = 1 ) — [optional] Number. The scale multiplier along the y axis. Default is 1.
| |
factorZ:Number (default = .5 ) — [optional] Number. The scale multiplier along the z axis (the elevation factor). Default is .5.
|
traceLevels | () | method |
public function traceLevels(sourceBmd:BitmapData, channel:String = r, subdivisionX:int = 10, subdivisionY:int = 10, factorX:Number = 1, factorY:Number = 1, elevate:Number = .5):void
generates the smooth representation of the geometry. uses same parameters as the Elevation class.
