Because of their paper (LaTeX) FIG many data are plotted using matlab, first drawing and then save the picture as in matlab pdf, FIG thus obtained can be amplified without distortion. But the recent discovery, save with three-dimensional graphics rendering into pdf matlab after amplification distortion still do not know why the two-dimensional graphics without distortion, but the distortion of the three-dimensional graphics :( reasons not find, but to find a solution:
1. Point the mouse to show up in matlab Figure, (I use the matlab 2019b), this time in a row gray icon appears in the upper right corner of the picture:
2. Click on the first icon, the drop-down menu will appear three icons, click on the third icon (copy vector drawing), at which time the drawing vector map has been in the pasteboard, and we need to do is to find a place, Ctrl + V it.
3. Open visio, creating a "blank drawing", and Ctrl + V, this time has been copied to the vector diagram visio in the drawing and then stored into the visio to pdf.
Completed the above steps, the resulting PDF larger image will not be distorted after it!
