Hello,

I'm trying to create a custom UI based on some existing textures.
The textures I have contain multiple things in the same blp file. Is there a way to crop, from the texture, the part that I need in a WA?

Thanks

nova scroll Nov 15, 2022, 10:06 AM

#

There is no way to do this directly in wa?

loud minnow Nov 15, 2022, 11:46 AM

#

That's a atlas and if you wait for the next release it has atlas support

torn jasper Nov 15, 2022, 12:00 PM

#

Texture WA already support using atlases. The only thing that's coming (if I understand correctly) is the ability to select atlases from a picker.

#

The trouble here may be that the regions of the image may not actually be existing atlases. Certainly back in Wrath Blizz used to just use TexCoords more often. I'm not sure when atlases were introduced.

AHH wotlk

torn jasper Nov 15, 2022, 12:01 PM

#

If @nova scroll has atlas names then they should use them directly instead of a path/fileID for the whole image

nova scroll Nov 15, 2022, 1:54 PM

#

I'm not sure I'm familiar with the atlas 😄 is this something new?

torn jasper Nov 15, 2022, 1:56 PM

#

A "texture atlas" is a term for what you're describing. A region within a larger image.
In the game's API this is also a system where texture regions are predefined with names that can be used in texture:SetAtlas(atlasName).
Unfortunately users can't add atlases so this can only be done for stuff that Blizz set up.

#

For anything of your own, or without a Blizz atlas, you'll need TexCoord

nova scroll Nov 15, 2022, 1:57 PM

#

oh ok, but that should actually be fine in my case. Cause what I'm trying to do is build a custom UI but heavily inspired from the default one, just customised in different places

#

thanks a lot 🙂

#

I'm going to try to see if the textures I need were exposed as atlases in wotlk

torn jasper Nov 15, 2022, 2:00 PM

#

If TextureAtlasViewer (addon) works on Classic then that'll be a help.

nova scroll Nov 15, 2022, 2:08 PM

#

it does 🙂

#

just installed it and I'm playing around with textures now

loud minnow Nov 15, 2022, 2:10 PM

#

Someone mentioned in another channel that apperantly the legion and earlier files and atlases being there, can you check that?

nova scroll Nov 15, 2022, 2:10 PM

#

but I think you were right, the atlases in there were "bigger" images, e.g. I created a texture WA using the following Atlas:

#

and on the right you can see how it shows

#

there are quite a few atlases, Legion as well

#

#

ok, but I'm not sure I know now how I could crop a part of such an atlas (if that's possible). E.g. from the first picture, how could I crop to eventually end up just with the gryphon?

#

I understand I have to use some Lua, not sure on where to put it (custom init event maybe?)

loud minnow Nov 15, 2022, 2:17 PM

#

It shows Zou a name, just using that name in a texture aura with maybe some checkbox, not sure right now, should give you that image.
But asakawa knows more there

torn jasper Nov 15, 2022, 2:18 PM

#

AFAIK everywhere in WA that takes a path or fileID will accept an atlas name

weak umbra Nov 15, 2022, 2:18 PM

#

if you use alpha version of weakauras you can just do this

loud minnow Nov 15, 2022, 2:19 PM

#

Looks squished.

torn jasper Nov 15, 2022, 2:19 PM

#

Nah, the interface is stretching it to square

nova scroll Nov 15, 2022, 2:19 PM

#

Well, I can adjust it, beeing a bit squish is not a problem

weak umbra Nov 15, 2022, 2:19 PM

#

preview is but region adapt size automatically

nova scroll Nov 15, 2022, 2:20 PM

#

Ok, I'll install the alpha then 😁

#

I can get it from GH right?

weak umbra Nov 15, 2022, 2:20 PM

#

like

loud minnow Nov 15, 2022, 2:20 PM

#

Just now you can also just use the name the add-on shows you

#

The alpha adds basically what the add-on does

weak umbra Nov 15, 2022, 2:20 PM

#

try type hud-MainMenuBar-gryphon

nova scroll Nov 15, 2022, 2:21 PM

#

That's what I used

#

Let me login again and double check

weak umbra Nov 15, 2022, 2:21 PM

#

but if i remember there are dirty offsets, which is fixed in alpha

torn jasper Nov 15, 2022, 2:21 PM

This just looks like you aren't using the correct "clamp" setting

#

Or, not switching off Full Rotation

weak umbra Nov 15, 2022, 2:22 PM

#

nah a little zoom was applied idk why

#

removed that

torn jasper Nov 15, 2022, 2:23 PM

#

I'm talking about the screenshot they posted above

#

nova scroll Nov 15, 2022, 2:24 PM

#

ok, I've exported the one I created so it may be easier to understand what I did

torn jasper Nov 15, 2022, 2:24 PM

#

Sadly the clamp settings can't help with an atlas like this so you simply can't use full rotation

nova scroll Nov 15, 2022, 2:24 PM

torn jasper Nov 15, 2022, 2:25 PM

#

As I said, simply untick Full Rotation.

#

There's no need to use Alpha WA

nova scroll Nov 15, 2022, 2:25 PM

#

oh right right

torn jasper Nov 15, 2022, 2:25 PM

#

You already have the atlas you want and can browse for more with TAV

nova scroll Nov 15, 2022, 2:25 PM

#

thanks, it works with that 😄

weak umbra Nov 15, 2022, 2:26 PM

#

if you need size without distortion

torn jasper Nov 15, 2022, 2:26 PM

#

Aha, I was just typing up something regarding that

#

If you're putting in a browser then the atlas dimensions really do matter

nova scroll Nov 15, 2022, 2:27 PM

#

yep, I noticed the width and height is in TAV, I'm going to rely on that 🙂

torn jasper Nov 15, 2022, 2:28 PM

#

@weak umbra Personally I'd want to see the images in the browser as the true atlas size, or at least the correct atlas dimensions, scaled up to fit. But also once selected the user needs to know the dimensions really.

weak umbra Nov 15, 2022, 2:29 PM

#

it edit size of aura when you select (then you do whatever you want)

torn jasper Nov 15, 2022, 2:29 PM

#

Oh it does? That's great

weak umbra Nov 15, 2022, 2:29 PM

#

but yah for preview ..

#

yup that where those 128/76 come from

#

just clicked it

torn jasper Nov 15, 2022, 2:31 PM

#

That's nice. Like WA can't easily compete with TAV's visual way of browsing for items but things like that definitely offer a reason to use it.

weak umbra Nov 15, 2022, 2:31 PM

#

i love playing with this 😄

torn jasper Nov 15, 2022, 2:32 PM

#

I did a quick thing in rehack for atlas scaling up, without warping. Just a proof of concept so can probably be cleaned up a bit

if not f then
   f = CreateFrame("FRAME")
   f.t = f:CreateTexture()
end
f:SetAllPoints("UIParent")
f:Show()
f.t:SetPoint("CENTER")
f.t:SetAtlas("_128-GoldRedButton-Center", true)
local w,h = f.t:GetSize()
if w > h then
   local prop = 100/w
   f.t:SetWidth(100)
   f.t:SetHeight(h*prop)
elseif h > w then
   local prop = 100/h
   f.t:SetWidth(w*prop)
   f.t:SetHeight(100)
else
   f.t:SetSize(100, 100)
end
f.t:Show()

#

I take it Ace fights you on this stuff though?

weak umbra Nov 15, 2022, 2:36 PM

#

im looking into it

weak umbra Nov 15, 2022, 2:59 PM

#

100/w should be h/w

#

and 100/h should be w/h

torn jasper Nov 15, 2022, 2:59 PM

#

I was scaling to 100x100 specifically

#

But yeah, I guess just finding the proportion of the 2 is simpler 😄

weak umbra Nov 15, 2022, 3:00 PM

#

got it working with this

      local atlasInfo = GetAtlasInfo(texturePath)
      self.texture:SetAtlas(texturePath, false);
      self.texture.IsAtlas = true
      if atlasInfo.width > atlasInfo.height then
        self.texture:SetSize(120, 120 * (atlasInfo.height / atlasInfo.width))
      elseif atlasInfo.height > atlasInfo.width then
        self.texture:SetSize(120 * (atlasInfo.width / atlasInfo.height), 120)
      else
        self.texture:SetSize(120, 120)
      end

torn jasper Nov 15, 2022, 3:00 PM

#

Very neat 👍

weak umbra Nov 15, 2022, 3:02 PM

#

torn jasper Nov 15, 2022, 3:02 PM

#

Yeah, right now, I'd use WA over TAV probably. Even for other projects.

nova scroll Nov 15, 2022, 3:27 PM

#

where could I download the latest alpha version of WA? 🙂

torn jasper Nov 15, 2022, 3:29 PM

#

If you use Curse (or similar) then you can probably set your preferred version to Alpha. Just remember to set it back again later if you don't want to actually be alpha testing potentially broken stuff
