Thesis reduction

1、 such as jpg The format picture is 5M, After opening , Re screenshot get 2M Of png file , Then import latex compile , And then in Adobe Medium optimized size , Its size has not improved （ Compared with the original optimization ）

2、 The larger eps picture ( Non vector graph ) by 15M, After opening , Re screenshot get 2M Of png file , Then import latex compile , And then in Adobe Medium optimized size , Its size can be optimized ！！！

3、Adobe When optimizing , Whether it's lowering dpi Or will it “ quality ” Adjusted for “ low ”, Can reduce pdf size , But the sharpness of non vector images decreases , The clarity of the vector image remains unchanged
