| Parameter | Description |
|---|---|
| lineTex | The AA texture used for rendering. |
| width | The width of the line. |
| points | List of points to build the line from. |
| colors | The colors to apply to each point. Must match the length of the points array or actualNumberOfPoints, whichever is lower and greater than zero. |
| actualNumberOfPoints | The total number of vertices to draw of the points array. Use this to keep a reusable buffer of point values without the need to resize frequently. |
Draw anti-aliased line specified with point array and width.
Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.
Note: To get an anti-aliased effect use a texture that is 1x2 pixels with one transparent white pixel and one opaque white pixel.
