| #define | TimeToScreen(t, scale, scroll) (int(floor((t)*(scale)+0.5)) - (scroll)) |
| | Given a TimeValue t, if you have the time scale and time scroll factors, this macro returns the screen space X for that time. More...

| |
| #define | ScreenToTime(s, scale, scroll) ((int)floor((s)/(scale) + (scroll)/(scale)+0.5)) |
| | Given a screen coordinate s, if you have the scale and scroll factors, this macro will return a TimeValue for that screen position. More...

| #define | ValueToScreen(v, h, scale, scroll) (h-int(floor((v)*(scale)+0.5)) - (scroll)) |
| | Given a Value v, if you have the value scale and value scroll factors, this macro returns the screen space Y for that value. More...
|
| |
| #define | ScreenToValue(s, h, scale, scroll) ((float(h)-(float(s)+float(scroll)))/(scale)) |
| | Given a screen coordinate s, if you have the scale and scroll factors, this macro will return a value for that screen position. More...
