read args parm bug or clarification needed

[rolanday]

Great contribution. Thank you!

AFAICT, should be able to scope query to return tags listed in read args array as shown in following example:

read('./image.jpg', ['-Model', '-Make', ...])

Is this unsupported, bug, or on me?

Thanks again,

-Roland.

Hey @rolanday. Yeah, it's unsupported. Here's the discussion: #44

TL;DR: If you only want Make and Model, you're using the wrong library. There are faster ways to do that.

[mceachen]

OK, I thought of a way to do this and not break all the things. Please read the docs carefully before using! https://exiftool-vendored.js.org/classes/exiftool.html#readraw

[rolanday]

Thanks for the quick replies.

Above snippet was just to illustrate and definitely need a much fuller set of metadata. I'll take a look at your link (thank you!) but this isn't a deal breaker for me either way -- just about perf tuning and wanting to measure impact from reduced set of tags to read.

Thanks again!

Please share any performance numbers (and if you can, the benchmark code and example image inputs). If there's better performance we can wrestle out of this module, I'm all ears.

[rolanday]

I will do that. I'm quite pleased the perf relative to the perl implementation of app logic I'm porting to js so can leverage node / electron -- about 2-3x faster thanks to the parallelism and not reloading ExifTool. You did your homework!

Thanks again :-)
