Problem Description:
PDF is a good choice for inserting pictures in Latex. However, if we want to export the pictures we edited in VISIO to PDF format and use them in the paper, we may encounter white borders and black pictures. The wireframe situation will be solved one by one below.
Remove white border from picture
Under normal circumstances, after we create the picture, we will select [Design]-[Size]-[Adapt to Drawing]
Doing this, by default, a few millimeters of white border will exist
Solution:
[Menu Bar]-[File]-[Options]-[Customize Ribbon]-check [Development Tools]-[OK]
Then in the menu bar [Development Tools]-[Show ShapeSheet]-[Page]-[Print Properties]
Change [PageLeftMargin], [PageRightMargin], [PageTopMargin] and [PageBottomMargin] to 0, then close the development tools column
Go back and click [Design]-[Size]-[Adapt to Drawing] again, and the white border will be gone.
Remove black wireframe
If it is a picture with a white background, the PDF file exported directly in VISIO and the picture generated by importing it into Latex will have a black line frame, which is not good-looking.
The solution is also very simple: when saving as PDF, click [Options]
Uncheck [Accessibility Document Structure Markup]
Then the exported picture will have no black wireframe.
