The new Images is here

[timholy]

As discussed in #542. See the documentation at JuliaImages (the documentation will be fully up to date only after this is merged and tagged).

Fixes #73, #124, #187, #267, #319, #368, #375, #367, #386, #447, #449, #451, #471, #539, #542, #545, #553. That should be enough for now 😄.

This interacts with many other packages, and I've realized that many people might have a subset of packages checked out on master and another subset following released versions, so it will be too disruptive to wait a week or so before tagging (as I had indicated at one point). Consequently, I'm tagging as soon as this merges.

It would be great if QuartzImageIO could update fairly soon (JuliaIO/QuartzImageIO.jl#28), since Mac users are going to encounter trouble until that happens. I've given rather a lot of warning about this, hoping to have a PR queued already, but since little has changed since October it looks like we'll just have to figure it out after the fact.

[timholy]

That felt good.

[timholy]

Oh, and there's a new file here that is intended to help with folks with migration; basically a "how do I get around this error message?" FAQ.

[vchuravy]

That felt good.

Congratulations! 🎉

Worth adding bounds for ImageView and ImagineFormat?

[timholy]

ImageView is already updated. (Part of my mistaken direct-push to METADATA.jl). Don't worry about ImagineFormat, there's already a branch that folks can use. Just mulling over whether I should make more changes first.

[tkelman]

It's already updated if people are using the latest version of ImageView, but if they try to use any older versions of it against the latest Images it isn't going to work.

[timholy]

Then sure, it would be fine. Thanks again!

[tkelman]

Oh, hah, you already did -
https://github.com/JuliaLang/METADATA.jl/tree/metadata-v2/ImageView/versions
https://github.com/JuliaLang/METADATA.jl/tree/metadata-v2/ImagineFormat/versions

the failures were just because there wasn't a new tagged version to test from yet.

[rsrock]

Quick question here. Is that how you add an upper bound to already tagged and published versions, by editing the REQUIRES files in METADATA? I'll have to do the same thing soon for QuartzImageIO.

[tkelman]

Yep. I can help you through it if you need any help.

A simple load of a PNG file fails:

img = Images.load("any_test.png")

[timholy]

If you're on mac, for now first say using ImageMagick. (Thanks to @rsrock, QuartzImageIO is almost fixed, JuliaIO/QuartzImageIO.jl#29.)

[rsrock]

That's right. I'm taking the chance to clean up a few more bits, but hopefully the fixed QuartzImageIO will land today.

Pkg.add("ImageMagick")

resolved all the issues. Thank you very much!
