Right now Rev uses the OS APIs to get the file info, so it's about as efficient as it can be. I can see the benefit of using EXIF, but since this requires additional work and processing time, and only applies to a subset of a very small number of file tyes, this sounds like an excellent candidate for an external. Anyone here interested in writing it? -- Richard Gaskin Fourth World Media Corporation
I do not know if he is interested and would have the time, but I think Alex Tweedly, author of the wonderful "libEXIF" stack, would be the ideal candidate.
I have tried to "tweak" his stack a little to retrieve the "original dates" from all image files of a folder. Execution time per image file is from 13 to 40 milliseconds depending on what amount of date I get from the "original date" line of Alex's variable "alltags" (i.e. only the "original date" or with filename and/or seconds etc.).
I left the stack script intact and edited only the "test" button to get only the original-date lines. This means that the stack - as before - first retrieves *all* EXIF data in the stack script before only the date line is accessed from the changed button script.
Would Alex rewrite his stack script to concentrate on the "original date", I believe the execution speed per image file would be only about 5 milliseconds or even less. An external based on his algorithms would surely be astonishingly fast.
