Short side resolution ratio 1080px is greater than 720px, and the short side resolution ratio 4000px of picture 2 is compressed to 1080px, compression ratio are as follows:
1080px/4000px=0.27, since the long side resolution ratio 6000px of picture 2 is greater than 1024px, by the long side resolution ratio of picture 2
6000px is according to 0.27 equal proportion boil down to 6000px × 0.27=1620px of compression ratio, finally by 2 boil down to 1620px of picture
×1080px；
When the resolution ratio of mobile phone is 1920px × 700px, the short side resolution ratio 1200px of picture 1 is greater than the short side of mobile phone
Resolution ratio 700px, and the short side resolution ratio 700px of mobile phone is less than 720px, and the short side resolution ratio 1200px of picture 1 is compressed to
720px, since the long side resolution ratio 1000px of picture 1 is less than 1024px, by the long side resolution compression of picture 1 to 1024px,
Finally by 1 boil down to 1024px × 720px of picture；The short side resolution ratio 4000px of picture 2 is greater than the short side resolution ratio of mobile phone
700px, and the short side resolution ratio 700px of mobile phone is less than 720px, and the short side resolution ratio 4000px of picture 2 is compressed to 720px,
Compression ratio are as follows: 720px/4000px=0.27, since the long side resolution ratio 6000px of picture 2 is greater than 1024px, by the length of picture 2
Side resolution ratio 6000px finally compresses picture 2 according to 0.18 equal proportion boil down to 6000px × 0.18=1080px of compression ratio
For 1080px × 720px.
