|
Parameter |
Description |
|
wX_Start |
X-coordinate of the full arc's start point. |
|
wY_Start |
Y-coordinate of the full arc's start point. |
|
wX_Stop |
X-coordinate of the full arc's stop point. |
|
wY_Stop |
Y-coordinate of the full arc's stop point. |
|
wRadius |
Radius of the arc (must be larger than the distance between the start and stop points). |
|
pCurve |
Arc curvature direction: |
|
wColor |
16-bit RGB565 color for the arc radius line. |
|
swStartOffset |
The starting offset of the radius line from the arc. |
|
swEndOffset |
The ending offset of the radius line from the arc. |
|
fSegment |
Fraction (0 to 1) specifying the position on the arc to which the radius line will point: |
This function draws a line from the arc's center to a specific point along the arc at a defined fraction (fSegment).
The line points to the segment of the arc determined by fSegment and can be offset from the arc using swStartOffset and swEndOffset.
To make use of this function, the line thickness should be set previously using TftArcRLThickness().
