Subject Re: Signature lost when converted from PDF to jpg

Hi,

I can display it. Did you get a log message like this?

Cannot read JPEG2000 image: Java Advanced Imaging (JAI) Image I/O Tools 
are not installed

Please read
https://pdfbox.apache.org/2.0/dependencies.html

The link to jai is broken... it's either a file named jai_imageio.jar 
that you have somewhere, or 
http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-java-client-419417.html

, or the files from
https://github.com/jai-imageio/jai-imageio-core
https://github.com/jai-imageio/jai-imageio-jpeg2000

ppt转jpg pptx转jpg图片是互联网时代最佳展现方式。除了直接管理图片资产以外,数据笔记对视频自动截屏,将Word/PPT/pdf转jpg转换,让内容在任何时候,任何平台上,随时可见。
