ATripathi Posted February 7, 2021 Share Posted February 7, 2021 Hello everyone, I have become big fan of AP and I think this is a perfect software for photographers on budget with great features and flexibility. I only recently started using AP (actually only recently started photography altogether). My workflow is probably not the best but it is what I have settled on. I do raw processing on a different software and then use AP on the exported tif file. I was really excited about the linked file feature mainly due to the potential of decreasing the file sizes of afphoto . I tried with a tif file and few simple curves and still the file size was 215 MB or so. Just to test, I deleted every image layer and just left the curve layers and the file size actually increased. I removed even the curve layers and saved a empty file which ended up being roughly 200 MB. I am not sure what is being saved when there is no layer to save such that the file size ended up this large. Am I missing nay settings (Save history is not enabled). Thank you for your help.

ATripathi Posted February 7, 2021 Author Share Posted February 7, 2021 An Update - Tried identical process except started with a blank canvas (exact same size, same DPI and color profile). Save size - 7 KB Added linked image (same as above) - < 1 MB Similar processing - curves with masks and such. Final afphoto file size : ~20 MB. This makes a lot more sense to me.

Staff Dan C Posted February 23, 2021 Staff Share Posted February 23, 2021 Hi @ATripathi, Welcome to the Affinity forums and my sincerest apologies for the delayed response here!

I removed even the curve layers and saved a empty file which ended up being roughly 200 MB. That's certainly strange behaviour, Affinity has a process whereby we don't discard data from a file until it has changed a 'significant' amount, I believe the delta is around 25% before this kicks in and removes the old data from the file. However with your description of the layers removed from the file I would have expected this to have kicked in and 'streamlined' the file. If you still have a copy of this file, would you mind opening it and performing a 'Save As' and letting me know if the newly saved file is closer to the expected file size?

This certainly sounds like much more reasonable behaviour, I can only assume that the application did not correctly detect enough of a 'change' in your previous file to discard the unnecessary data. As this isn't something I've had reported previously, I am confident it should not happen again - but please do let us know if you have any further issues here Quote Please note - I am currently out of the office for a short while whilst recovering from surgery (nothing serious!), therefore will not be available on the Forums during this time. Should you require a response from the team in a thread I have previously replied in - please Create a New Thread and our team will be sure to reply as soon as possible. Many thanks!

When Affinity opens (not imports/places) a TIFF or other image file, a new Affinity document is initialised with a Pixel object named "Background" generated from the image, and it stores a snapshot (also named "Background") of that initial state in the document. Deleting the Pixel object does not delete the snapshot, but you can use the Snapshots panel to do that. Quote Link to comment Share on other sites More sharing options...
