MyOffice Presentation supports slide numbering configured in third-party editors:
•Numbering is supported in files in .odp, .pptx and .ppt format.
•Slide numbers can be placed either in headers and footers or in objects (shapes or tables).
•Numbers are automatically added to new slides.
•When you add and delete slides, the subsequent slide numbers are automatically updated.
•Slide numbers are displayed when printing.
After making changes, you should save the file with numbering in .xodp, .pptx or .pdf format.
