1033。
In order to avoid initial preview resolution ratio adjusted is less than screen resolution, so that preview effect is influenced, it will be horizontal
Lesser one in the ratio between the ratio between pixel number and Vertical number of pixels, it is determined as preview ratio.For example, initial preview resolution ratio is
3264*2448, screen resolution 1920*1080, the ratio between Vertical number of pixels 3264/1920 are less than the ratio between Horizontal number of pixels
2448/1080, the ratio between Vertical number of pixels is determined as preview ratio；Initial preview resolution ratio is 3264*2448, screen resolution
For 1280*1024, the ratio between Vertical number of pixels 3264/1280 is greater than the ratio between Horizontal number of pixels 2448/1024, by Horizontal number of pixels it
Than being determined as preview ratio.
