Feature request - add $(FILE_SIZE) as variable

[Gododdin]

Is your feature request related to a problem? Please describe.

I have a large collection of images taken in various formats (including several hundred scans from transparencies) over many years which I'm trying to organise. When looking at either identical or visually very similar images it's important for me to be able to quickly see which is the largest file size so that I can keep it and delete the others.

Describe the solution you'd like

It would be extremely useful if a variable $(FILE_SIZE) could be implemented so that I can add this to the thumbnail tooltip variable string and see at a glance which of two or more files is largest. Thanks!

Well this is non trivial as the size of the image is currently not known from dt. We would need to get it at import time and add it into the database.

@wpferguson : Maybe a Lua script could do that?

@TurboGit either your ESP is working overtime, or mine is.

For the last week or so I've been trying to figure out a solution to adding image metadata fields that doesn't

• take 6 months to get released
• take hundreds of lines of code
• clutter up the database with all kinds of maker specific features

This kind of fits right in there.

Off the top of my head we could

• run on import, or by shortcut (to process already existing collections)
• attach a tag to the image like metadata|file size|<size in ?>

That way you could use the tag in variable substitution, or to sort on in the collections module

Thanks for your answers. I'm afraid I'm not a programmer (I'm an artist) so your responses are a bit 'opaque' to me. :) But that sounds ideal if it's possible. Mostly I would be into processing existing collections as most of that work is already done but it's also useful when adding images of course.

I'm not sure if a tag would work here as we want to select all files whose size is less than some value.

[wpferguson]

I missed the part about the tooltip. Thinking....

[Gododdin]

I'm not sure if a tag would work here as we want to select all files whose size is less than some value.

If I understand you correctly this is not really the case. No 'action' as such is required just the size information displayed. All I want is to know the size (at a glance if possible). The selection decision can then be left up to me. I mean, it would be great if a 'deduplicate' module could identify the largest of a set of identical/visually similar images and delete the rest but that seems too much to ask for.

Thanks again for your interest in this!

I'll play and see with I can come up with 😁

Like this?

I attached a tag to the image, metadata|file_size|XXXXXK, then use the variable $(CATEGORY[1,metadata]) to display it. I want to tune a little bit and test on windows also.

EDIT: Played with the variables a little bit until I figured out how they worked.

If I attach a tag metadata|file size|20480K to an image I can get the 20480K to display with either $(CATEGORY[1,metadata]) or $(CATEGORY(0,metadata|file size]) of which the second would be better if we wanted to make more metadata categories. I also created a tag file size|20480K and that can be displayed with just the $(CATEGORY(0,file size])

EDIT 2: I hate windows! It's working on windows too as long as you don't have filenames with accented characters in them. Lua also can't convert number strings from the file system into actual numbers so the file size is in shown in bytes.

[TurboGit]

@wpferguson : At least there is this information in the thumbs, but as discussed earlier this won't help to select images whose size are less than some value.

[Gododdin]

Looks great to me! Personally I would prefer to see it in the format shown here (kb rather than bytes) but that's not a big deal.

[wpferguson]

(kb rather than bytes)

Me too, I just have to figure out a way around windows character encoding (but I have and idea).

this won't help to select images whose size

He's selecting groups of images based on appearance then using the tooltip to find the one he wants to keep. However, if we enhance the collection module so that we can click then shift-click or ctrl-click to add additional values from a tag then we could 😁
