CleanPolyline

CleanPolyline(pointArray)

Returns: Polyline struct

Argument	Name	Purpose
0	pointArray	Array of x/y coordinate pairs for sequential points on the polyline

N.B. A shape will only draw when you call the .Draw() method. Polylines tend not to cope well with very sharp angles so be careful about the geometry you're trying to draw.

 

Polylines have the following methods:

 

.Draw()

Argument	Name	Purpose
None

 

.Blend(color, alpha)

Argument	Name	Purpose
0	color	Color of the line
1	alpha	Alpha value of the line

 

.BlendExt(blendArray)

Argument	Name	Purpose
0	blendArray	Array of color/alpha pairs corresponding to points on the polyline

Multi-vertex blending uses triangle-based interpolation and can look ugly with large differences in colour. Use with caution!

 

.Thickness(pixels)

Argument	Name	Purpose
0	pixels	Width of the line

 

.Cap(startType, endType)

Argument	Name	Purpose
0	startType	Cap type for the start of the line, either "none", "square", "round", or "closed"
1	endType	Cap type for the end of the line, either "none", "square", "round", or "closed"

If either cap type is "closed" then the polyline will be a closed loop with no caps.

 

.Join(type)

Argument	Name	Purpose
0	type	Join type, either "none", "miter", "bevel", or "round"
