Draw an ellipse
int PgDrawEllipse( PhPoint_t const *center, PhPoint_t const *radii, unsigned int flags ); int PgDrawEllipseCx( void *dc, PhPoint_t const *center, PhPoint_t const *radii, unsigned int flags );
To have the function interpret the center and radii arguments as the upper-left and lower-right coordinates respectively, OR flags with Pg_EXTENT_BASED.
ph
These functions build a command in the draw buffer to draw an ellipse. PgDrawEllipse() works on the current draw context, while you can specify the draw context for PgDrawEllipseCx().
The following example:
DrawStrokeElli() { PhPoint_t c = { 80, 60 }; PhPoint_t r = { 72, 52 }; PgSetStrokeColor( Pg_WHITE ); PgDrawEllipse( &c, &r, Pg_DRAW_STROKE ); }
will draw:
The following example:
DrawFillElli() { PhPoint_t c = { 80, 60 }; PhPoint_t r = { 72, 52 }; PgSetFillColor( Pg_PURPLE ); PgDrawEllipse( &c, &r, Pg_DRAW_FILL ); }
will draw:
The following example:
DrawFillStrokeElli() { PhPoint_t c = { 80, 60 }; PhPoint_t r = { 72, 52 }; PgSetFillColor( Pg_PURPLE ); PgSetStrokeColor( Pg_WHITE ); PgDrawEllipse( &c, &r, Pg_DRAW_FILL_STROKE ); }
will draw:
