A new version of Caption Pro is available here and a new standalone version of ImageSplit is available here. Caption Pro now handles HEIC images from Apple iPhones and has improved handling of non-JPEG files. ImageSplit now uses a white background outside the scanned or loaded file area for rectangle detection. This improves automatic detection where photos are close to edges. Hotkayes have been added for the Scan and Save Split functions.
Note that ImageSplit can be accessed from Caption Pro using the Caption Pro license and is installed as part of Caption Pro. An ImageSplit license is only required for standalone ImageSplit operation. For details of changes see release notes for Caption Pro here and for ImageSplit here.
