RGBX not defined

[jakewilliami]

Trying to load QuartzImageIO does not seem to work: I get an error saying RGBX not defined (see below). After I ran what is depicted below, I tried adding and using Colors and ColorTypes, but I am getting the same error. As per the readme, I have also tried just using FileIO and loading a jpg, but cannot get this working (same error).

Tested on Arch Linux and is working fine. I am using a MBP, running Mojave (10.14.6). Both machines are using Julia 1.5.1.

[johnnychen94]

should be fixed by JuliaIO/Netpbm.jl#21

ColorTypes v0.10 is required for RGBX, Netpbm locks it down to v0.8

[johnnychen94]

could also be fixed by #69

[jakewilliami]

Thanks for identifying the problem @johnnychen94. Do I need to wait for the pr to be merged into Netpbm, and then run pkg> update?

[johnnychen94]

Whichever PR merged and tagged for a release, an pkg> update would get you back on track.

@jakewilliami, JuliaRegistries/General#21160 should auto-merge in 15 minutes and you'll be set.

@johnnychen94, if you think #69 is desirable even with the Netpbm update, I have no objections.

[johnnychen94]

Since we delegate the ColorTypes version resolving to ImageCore, and since ImageCore 0.8 declares compatibility for ColorTypes 0.8 and 0.9. For example, ImageCore 0.8 declares compatibility to Colors v0.11, which again declares compatibility to ColorTypes 0.9

We don't know if there are other packages like Netpbm that locks to the old versions and it would be better to get #69 in as preparation. Since it gets fixed by a new Netpbm version, we could ship #69 with potential new PRs in the future.

JuliaRegistries/General#21160 should auto-merge in 15 minutes and you'll be set.

Heads up to the General synchronization issue JuliaRegistries/General#16777 (comment) since Julia 1.5 uses PkgServer by default. The delay could occasionally be hours.

The delay could occasionally be hours.

Good to know, thanks @johnnychen94. No rush in my case 🙂
