I had a great week working on some fixes and prototype EXIF support.

EXIF

EXIF are metadata labels embedded in some media files, usually JPEG. They might say the make of camera that took a picture, or its aperture/ISO, the GPS coordinates it was taken at, how an image is rotated, or the DPI of a logo for printing purposes. There are many different possible fields. I have wanted to add support to view and even search this data for a long time, and this week we start with something simple but not user-friendly.

The media viewer now has a 'cog' icon on the top hover. On JPEGs, it lets you check for EXIF data. Most files don't have it, but if it does (usually this is photos or professional art exported from Photoshop etc...), it now throws up a little window to see every field.

The duplicate filter now actively scans for EXIF data and says if one or both files have it, just like the recent addition for ICC Profiles. Many websites strip EXIF data on upload, so if you have two exact dupes, the one with EXIF data is probably closer to the 'original' version.

Now I have this framework, I would like to extend it. Beyond general polish like replacing the cog icon with something nicer, and only enable it when I know there is some EXIF to show, I want to cache 'has exif data yes/no' in the database and allow you to search by that. I expect I'll also add the actual EXIF data itself to the database one day, so you'll be able to search all your pictures for iPhone 6 photos or whatever.

So, if you are interested in EXIF, please give this a go and let me know what you think. This feature was taking so long to happen that I decided to just spam out a rough v1.0 that I can keep improving.

full list

- EXIF:
- in the first step of 'official' EXIF support, the media viewer now has a 'cog' button on the top hover, enabled when looking at a jpeg, that will check the file for EXIF data. if found, it will throw it up on a simple new window that shows EXIF id, label, and value. this is a hacked-together prototype, not super user-friendly, but it works. let me know what you think, and please send me any files that have weird EXIF that doesn't parse right but you think should. I already discovered a file with a null character that wouldn't display in UI, that sort of thing
- GPS EXIF values are also parsed and extracted
- made it so you can double-click a row in this new window to copy an EXIF value to clipboard
- in the duplicate filter, if one or both files have exif data, this is now noted in the comparison statements, just like ICC profile! (issue #469)
- obvious future extensions here will be storing 'has exif' in the database and allowing its presence to be searchable and enabling the cog button (or a nicer 'exif' button) only when there is known data to see. a subsequent step would be actually caching the data in the database for full EXIF search
- as a side thing, we're now set up on the hydrus end to pull TIFF EXIF, but PIL doesn't seem to offer it, so we'll have to wait for a different solution there

- fixes and misc:
- fixed a problem that made saved page file sorts reset their sort order one time on update to v492. thank you to a user for noticing this and discovering the fix, and I'm very sorry for the inconvenience of changing your session and favourite search sorts. unfortunately there is no easy fix other than rolling back to a backup and jumping forward to this version
- fixed a v492 message display error when setting various duplicate relationships to three or more thumbnails at once. it was a stupid typo, sorry for the trouble! (issue #1199)
- if a page tab name elides to a 'shorter...' length, it now has its full name as the tooltip
- fixed a typo in update code error handling (issue #1192)
- the duplicate filter page now remembers if you are 'searching immediately'/'search paused' (issue #1193)
- if you are on non-Windows and export files manually or with an export folder to an NTFS or exFAT partition, this is now detected, and NTFS-invalid characters in the pattern-generated folders or filename are now replaced with underscores (issue #1194)
- 'fixed' a system predicate bug in the 'OR*' advanced predicate parser--entering a logical expression that results in a negated system tag now causes an error. previously, it would strip the 'system:' and just enter the given text as an unnamespaced tag. furthermore, that dialog now reports specific error reasons when it fails to parse. I hope to improve support for negated system tags in future--some stuff, like archive/inbox, should be easy.
- I think I fixed an instance where the archive/delete filter's confirmation dialog could present 'delete from hard disk' as an option when it wasn't appropriate
- in an attempt to reduce the media-change flickering we've recently seen in the media viewer, I untangled a bunch of the canvas size/position code this week. I'm preparing a complete overhaul and neat Qt layout integration, which this starts. I _think_ I've made some things less flickery on occasion, but we'll see IRL. much more to do
- added a '--profile_mode' launch argument, which allows you to capture the performance of boot and also try out profile mode on the server (although support there is very limited atm)

next week

Next week is a medium size job week. I want to put some time into note parsing. I am not sure how far I can get, but fingers crossed I can actually get 'note import options' and a note content parser working, and we'll be able to update the existing downloaders to grab artist notes and things.

Don't know what I'm supposed to do to fix this or if it was broken before.
Hydrus v464, first time I've opened it in a few months and says you want feedback.

Ah, damn, I think that login script does not work any more, I think I remember another user saying this recently. If any script suddenly breaks, I recommend you disable the login (set it to 'active: no' under manage logins) and use Hydrus Companion instead, which will sync your cookies over from your logged-in browser and works a lot better for all unusual situations:

I will see about removing that rule34.xxx link in the defaults so new users don't get hit by this either.

Is there a way to change the upper limit on gifs from 32?
I'm trying to save a 52Mb sized gif and I got prompted with this message.

Release Tomorrow! Anonymous Board owner 08/03/2022 (Wed) 03:13:40 Id: 7d71d1 [Preview] No.1332 del

I had a great week with two big changes. First, there are Qt6 test builds for advanced users to try out, and second, in prep for a soon-to-come Note Import Options, I added filetype filtering and 'use default at time of import' tech to File Import Options.

The release should be as normal tomorrow.

Sure, check the 'File Import Options' of the importer you are working on. There's a setting in there just for gif size. options->importing for your default settings.
