image - 电晕中的 display.newImage() 与 display.newImageRect()

Question

display.newImage() 和 display.newImageRect() 有什么区别？

哪个更好用？

Answer 1

display.newImage() 的文档具体提到:

NOTE: display.newImageRect() should be used instead to load images when dynamic content scaling is enabled.

同样，在 display.newImageRect() 上

dispaly.newImageRect() automatically substitutes higher-resolution assets on higher-resolution devices. The actual image chosen will depend on the current content scale determined by Corona, which is the ratio between the current screen and the base content dimensions defined in config.lua.

Based on this scale, Corona uses the imageSuffix table (also defined in config.lua), which lists the suffixes for the same family of images, to find the best match from the image choices available.
