新版的编辑器真不适应，费劲！！！
Open title defense last two days to do ppt, ppt found a little trick in the background with pictures, here for everyone to share.
PPT usually with a background picture, the kind with a light colored logo, etc. (white ppt please ignore the following text). In this case insert a picture with a background will cover the background, it seems discordant (as shown below)!
So the general requirements for the background picture transparent, so that seems PPT overall consistency better. Before all external software to handle it, and later even found ppt which was able to directly remove the background!
step1: After you insert a picture, double-click the picture, the following figure appears, select recolor, Set Transparent Color
step2: click on the need to set up a transparent part of it, the effect is as follows, is not comfortable, simple and convenient.
