本文介绍了Mac OS X v10.5及以上版本中NSImageScaling枚举类型的四种常量：NSImageScaleProportionallyDown（按比例缩小）、NSImageScaleAxesIndependently（独立缩放每个轴）、NSImageScaleNone（不缩放）及NSImageScaleProportionallyUpOrDown（按比例放大或缩小）。这些选项定义了如何在不同场景下调整图像大小。
NSImageScaling
These constants specify a cell’s image scaling behavior.
enum {
NSImageScaleProportionallyDown = 0,
NSImageScaleAxesIndependently,
NSImageScaleNone,
NSImageScaleProportionallyUpOrDown
};
typedef NSUInteger NSImageScaling;
Constants
-
