We are happy to announce the release of Spire.Presentation 8.9.4. This version supports setting the time for automatic slide switching as well as setting and reading the transparency and brightness of gradient stop styles. It also enhances the conversion from slides to pictures. Besides, some known issues are fixed in this version, such as the issue that the collection of corner coordinates of polygons obtained was incomplete. More details are listed below.
Here is a list of changes made in this release
