Description

draw_circle_moddraw_circle_moddraw_circle_modDrawCircleModDrawCircleMod produces the parameter for a circle created interactive by the user in the window.

To create a circle are expected the coordinates RowInRowInRowInRowInrowIn and ColumnInColumnInColumnInColumnIncolumnIn of the center of a circle with radius RadiusInRadiusInRadiusInRadiusInradiusIn. After another mouse click in the created circle center you can move it. A clicking close to the circular arc you can modify the RadiusRadiusRadiusRadiusradius of the circle. Pressing the right mousebutton terminates the procedure. After terminating the procedure the circle is not visible in the window any longer.

Example (HDevelop)

read_image(Image,'monkey')
draw_circle_mod(WindowHandle,20,20,15,Row,Column,Radius)
gen_circle(Circle,Row,Column,Radius)
reduce_domain(Image,Circle,GrayCircle)
disp_image(GrayCircle,WindowHandle)

Example (C)

read_image(&Image,"monkey") ;
draw_circle_mod(WindowHandle,20,20,15,&Row,&Column,&Radius) ;
gen_circle(&Circle,Row,Column,Radius) ;
reduce_domain(Image,Circle,&GrayCircle) ;
disp_image(GrayCircle,WindowHandle) ;

Example (HDevelop)

read_image(Image,'monkey')
draw_circle_mod(WindowHandle,20,20,15,Row,Column,Radius)
gen_circle(Circle,Row,Column,Radius)
reduce_domain(Image,Circle,GrayCircle)
disp_image(GrayCircle,WindowHandle)

Example (HDevelop)

read_image(Image,'monkey')
draw_circle_mod(WindowHandle,20,20,15,Row,Column,Radius)
gen_circle(Circle,Row,Column,Radius)
reduce_domain(Image,Circle,GrayCircle)
disp_image(GrayCircle,WindowHandle)

Example (HDevelop)

read_image(Image,'monkey')
draw_circle_mod(WindowHandle,20,20,15,Row,Column,Radius)
gen_circle(Circle,Row,Column,Radius)
reduce_domain(Image,Circle,GrayCircle)
disp_image(GrayCircle,WindowHandle)

Result

draw_circle_moddraw_circle_moddraw_circle_modDrawCircleModDrawCircleMod returns 2 (H_MSG_TRUE) if the window is valid and the needed drawing mode (see set_insertset_insertset_insertSetInsertSetInsert) is available. If necessary, an exception is raised.
