amplification is not the purpose of 'contentsscale. The 'contentsscale' attribute is actually part of the screen mechanism that supports high resolution (also known as Hi-DPI or Retina. It is used to determine the size of the space that should be created for the host image when drawing the layer, and the degree of stretching of the image to be displayed (assuming that the 'contentsgravity 'attribute is not set ). UIView has a similar function, but r

formula is: The results are slightly out of the picture because the discrete sampling of pixels has a sawtooth effect. 6. Scaling factor (scale factor between logic point and device pixel) (1) Scale Origin The screen resolution of the early IPHONE3GS was 320*480 (ppi=163), and the iOS drawing graphics (cgpoint/cgsize/cgrect) were all measured in a point (measured in points): 1 point = 1 pixel(point per inch=pixel per Inch=ppi) Later, in IPhone4, the same size (3.5 inch) s
