512*512像素是300ppi吗 不是PPI是Pixels Per Inch缩写,pixels per inch所表示的是每英寸所拥有的像素(pixel)数目。因此300ppi表示的就是每英寸拥有的像素数目为300.手机屏幕的PPI当达到一定数值时,人眼就分辨不出颗粒感了。2010年时前苹果公司CEO史蒂夫·乔布斯(Steve

Since the launch of tiled web maps in 2005, there has been an implicit standard in mapping libraries: web maps are made up of many small, square images (known as “map tiles”) at a size of 256x256 pixels. Loading a bunch of small images made maps fast and performant — instead of...
