function AdvancedDrawAngle(AnglePoints: array of TPoint;
LineColor: TColor;
LineWidth: Integer;
const LabelText: String = '%s°';

): TRect;
Description
Draws an angle positioned at three points, optionally with text.
General Properties Parameter | Description |
AnglePoints | Specify the three points used to define the angle (where point 1 is vertex) |
LineColor | Color of the line |
LineWidth | Width of the line |
Text Label Parameter | Description |
LabelText | The string to output to the label. If %s is specified it will be replaced by the angle |
LabelFont | Optional: The font for the text. You can create a temporary TFont object, or specify NIL to use the Canvas.Font |
LabelDecimalPlaces | If %s is specified for the label, the angle will be displayed with this level of precision |
Other Parameters Parameter | Description |
AngleMode | Controls the behaviour of angle display |
AntiAlias | True uses best quality. False disables anti-aliasing |
CalculateOnly | If true, the text is not drawn, just the output size returned as the result |
Result is the size of the entire draw in pixels.
