coordinates (xGrid,yGrid) in grid to display coordinates (xDisp,yDisp) . |
| XgrConvertGridToLocal |
( grid, xGrid, yGrid, @x, @y ) XgrConvertGridToLocal() converts grid coordinates
(xGrid,yGrid) in grid to (x,y) local coordinates. |
| XgrConvertGridToScaled |
( grid, xGrid, yGrid, @x#, @y# ) XgrConvertGridToScaled() converts grid coordinates
(xGrid,yGrid) to scaled coordinates (x#,y#) for grid . |
| XgrConvertGridToWindow |
