Parameters
|
Parameter |
Description |
|
wX_Center |
X-coordinate of the polygon center |
|
wY_Center |
Y-coordinate of the polygon center |
|
bRadius |
Radius from the center to each vertex |
|
bVertexCount |
Number of vertices in the polygon (must be greater than 3) |
|
bStartAngle |
Starting angle from the Y-axis for the first vertex, then measured clockwise |
|
pSolid |
Polygon fill type: |
|
wColor |
Fill or outline color in 16-bit RGB565 format |
|
bWidth |
Outline thickness in pixels: |
Overview
- Other values specify additional outline width
sbDirection — Direction for additional outline width:
- 1: Outward
- -1: Inward
- Other values are ignored if there is no additional width
Draws a polygon with a specified number of vertices, starting from a given center point.
The polygon’s size is determined by the radius, and the starting angle controls the orientation of the first vertex.
If pSolid is set to 1, the polygon is filled with the specified color. If set to 0, only the outline is drawn.
The outline can also be customized in terms of width and direction.
