Hi, is it possible to write crop metadata (see http://photo.stackexchange.com/questions/43893/how-to-store-tilt-rotation-and-crop-information-in-metadata, xmp parameters for crop values) instead of actually performing the crop? I guess it is not a standard feature (at least I did not find it) but maybe it is possible with lua?
The background: I do a lot of design work with photographs from dt (calendars, photo books, etc.). Therefore, the photographs have to fit within given frames. When I crop in dt (e.g. in 2:3 format) and use it in a 4:5 template, I have to crop again, which is often not possible due to losing important image parts. For these situations it would be better to be able to "add" some picture at the other edges. Therefore, I have to go back into darktable, crop different, export again and reuse the image, which is cumbersome. Not cropping in dt is cumbersome as well since I want the exported image to appear as intended and the changes to make the image fit are only minor corrections, not changing the message of the image. Furthermore I use the images in multiple “products”, e.g. calendar and photo book. That means, I have to manually keep track of the initial intended crop and reproduce it for every purpose. On the other hand, initially doing multiple crops in dt would spam my lighttable and my export directories. Therefore I think writing crop to image metadata and exporting full size images sounds like a perfect idea. I guess the complementary functionality is not implemented in the tools that I use down the chain (inkscape, scribus and image viewers), but I have to start somewhere, and from the link above it does not sound too hard to do it. Any hints welcome :-) Thanks & best regards Chris ------------------------------------------------------------------------------ _______________________________________________ Darktable-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/darktable-users
