@傅明成 实测高亮是可以导出的，但附加的文字内容无法导出。 用户手册中也提到： Only your highlights are visible in the copy of the PDF.Any text you save for these highlights (quotations,comments, etc.) is not exported to the copy of the PDF.*
@yjLi 谢谢回复，原来这个Show all annotations是显示外部程序做的标注，是我理解错了…… 这几天看了下用户手册，关于我的这两个问题，程序目前是不支持这两个功能的，但个人感觉这两个功能还是很实用的，所以如果可以的话希望开发组可以加上这两个功能。
下附手册原文。 Margin and text highlights. When you’re done editing the comment, the text highlight will disappear. Only the margin highlight will remain visible. When you hover over the margin highlight, the text highlight will temporarily appear. Click the margin highlight to display the texthighlight.

It's no longer possible to insert images copied to the Clipboard into a text quotation. We've removed this possibility, since large embedded images have prevented projects from being saved in the cloud in the past. If you want to save an image as an quotation, you can use the Image quotation feature.
