PDF transparent background disappears in PowerPoint

Question

A PDF that I used previously in a Latex Beamer presentation has a transparent background. Yet when I put it in a PowerPoint presentation, it shows up with the white background. How can I fix it to have transparent background in PPT, as well?

Answer 1

在PowerPoint中，可以使用“格式背景”在选项“实心填充”，“图片或纹理填充”和“渐变填充”中设置透明度。
