PPT can normally export as PDF with very high resolution (the vectorized file). However, I encounter a weird problem today that cannot export a high resolution PDF. After “debugging” and “doing experiments”, I’ve finally found the problem. It’s because of the 3D format settings.
#To Make a long story short: Don’t use 3D formatting, if you want a vetor-quality PDF.
The Problem:
According to the need of a recent task, I need to design and draw a figure for a proposal. I did all the procedures as normal, but in the last step. I got the problem as mentioned above, the exported PDF file was with unacceptable quality. It looks obvious that the vector objects in the PPT was rasterized before saving. But I don’t know why.
Solution:
After at least one hour of various trials and analysis, I finally found that the PPT object will get rasterized when the 3D format is added to it.
Therefore, BEWARE when you have to use 3D format to get some special designs when you using PPT, remember that it will sacrafice the vector property of the objects.
