Converting .spmo files to .jpg format.
The .spmo file type is mostly used for SpeedView Meta Object files. This format was developed by Scalado AB.
SpeedView Meta Objects, .spmo files, only contain metadata used to speed up zooming of actual images. They do not contain actual images. An .spmo to .jpg conversion is, therefore, not possible.
In a word, direct spmo to jpg conversion is not possible.
So don't expect any so-called spmo to jpg converter or spmo to jpg free online conversion tool available.
The database currently does not contain any spmo software converter.
