PMView can read multi-page files. Multi-page files are files that can hold two or more images in the same file. Among the formats that can be handled by PMView, the following can hold multiple images:
Graphics Interchange Format (GIF)
Tagged Interchange File Format (TIF)
Please note that this version of PMView is not able to save files with multiple pages. Only the currently viewed page will be saved. However, we are planning to add support for writing multiple pages. If you have any suggestions for this feature, please let us know.
