Hi @vwsncr,

I tested online converter, it works fine for PNG file. Maybe you can try the offline version.

Hi , @jingpan 

    Thanks for reply!

    I have solved the problem . I tested different package of PNG decoder. The newest one (v8.3.0)works very well. But the JPG decoder package , i used old version from SDK's example. Do you think it is a good way?
