Allow to scale Texture resources

[JorensM]

Describe the project you are working on

Not a particular project, just general request

Describe the problem or limitation you are having in your project

When an image doesn't match the desired in-game size, I either have to scale each Sprite or resize the image file. This is quite cumbersome and I'd much prefer to just be able to scale the Texture itself

Describe the feature / enhancement and how it helps to overcome the problem or limitation

This will allow for easier and more intuitive texture scaling. It would also be in line with the principles KISS and DRY.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

I think it should be relatively easy to add this feature

If this enhancement will not be used often, can it be worked around with a few lines of script?

I think this would be used quite often if implemented

Is there a reason why this should be core and not an add-on in the asset library?

I think that this would be used often enough to warrant being part of core

This proposal doesn't really describe what you are struggling with. Godot already automatically scales images (or rather stretches them). See the image below:

Furthermore, it doesn't answer the answer how this should be implemented so I will convert this here to a discussion

[JorensM]

@paddy-exe sorry I messed it up I think. I was talking about how when you use an icon in a button, the icon will take up the real size of the image, regardless of the button's size. For some reason I was under the impression that it would be the same with Sprites.

[paddy-exe]

For Icons in a button you can use TextureButton which allows several StretchModes

[JorensM]

It seems that when using TextureButton you can't have the texture not take up the entire size of the button, and to have the texture alongside the text, instead of under it.

[paddy-exe]

If you want to use the Texture under the Text I would advise to create a new node for your project or compose it out of a Label and Sprite Node

[JorensM]

Ok, thanks, I guess I'll do that

There's a property in Texture2D to set its internal (i.e. rendered) size independently of its original size, but it's not exposed in the inspector. I can't find the issue that refers to it right now, but it definitely exists.

This kind of touches on a problem I had with one project. At one point I wanted to change prototype textures to higher resolution artwork. However, this resulted in all Sprite2Ds to double in size. As some sprites had animated scale, changing them was troublesome to say the least.
I think exposing Texture2D's size in importer would make sense for such cases.

[Calinou]

I think exposing Texture2D's size in importer would make sense for such cases.

It could be exposed in the inspector for sure; my main question is whether this should be exposed as a fixed pixel size (which would allow for aspect ratio distortion) or just a scale factor like SVG.

For your particular use case, you could set the render scale to 0.5 in the import options if we exposed a scale factor.
