Function

Draw an elliptic arc in the current color.

Header

tgi.h

Declaration

void __fastcall__ tgi_arc (int x, int y, unsigned char rx, unsigned char ry, unsigned sa, unsigned ea);

Description

The function draws an elliptic arc with center at x/y and radii rx/ry using the current drawing color. The arc covers the angle between sa and ea (startangle and endangle), which must be in the range 0..360.

Limits

• The function is only available as fastcall function, so it may only be used in presence of a prototype.
• The function behaves unexpectedly or may crash if the angles are out of range.
