Description Check the current zoom-in ratio for the screen capture region. Parameters None. Return Value The current zoom-in ratio for the screen capture region, which is either equal to or greater than 1.0. Remarks Use this function to check the current zoom-in ratio for the screen capture region. A ratio above 1.0 results in the screen capture region being zoomed in, while a ratio of exactly 1.0 maintains the region at its original size, with no zoom applied. The ratio must not be less than 1.0. Given that the ratio value is of type double, you can use a code snippet similar to the following to check if the ratio is equal to 1.0: `if (fabs(Ratio - 1.0) < 0.000001) { ...... }` See Also ScnLib_ZoomInScreen()
