1. Recently I was using h5 canvas to draw animations and found that the images were particularly blurry. Later, I finally found that the culprit was the code <meta name=viewport content=width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no />, because of this line Code is scaled
2. The effect of blurring images:
3. The effect after removing the compression
The code can be changed to
