BIFS Tutorial 2D Striking and Filling

Rules for shape striking:

If Shape.material is empty, the strike shall be done with a 1 pixel width, 0xFFCCCCCC line color (ARGB) without dashing. The shape shall not be filled.
If a Material2D is present in the material field, there are 2 possibilities:

If a LineProperties is present in the Material2D.lineProps field:

The strike width is LineProperties.width pixels.
Line color is LineProperties.lineColor.
If LineProperties.lineStyle is set, dashing occurs as follows:

lineStyle value	Description
0	No dashing
1	Dash
2	Dot
3	Dash Dot
4	Dash Dash Dot
5	Dash Dot Dot

If Material2D.lineProps is empty (default), striking is done with a width of 1 pixel and line color is Material2D.emissiveColor.

Rules for filling:

If a Material2D is present and the Material2D.filled field is 'true' , the shape is filled with the Material2D.emissiveColor. with a transparency (reverse alpha/opacity) of Material2D.transparency. Otherwise the shape is not filled.
