Texture fading on rescaling/resizing

[SanicBTW]

Hi everyone, I'm currently working on a project that uses sparrow spritesheets and I got the parsing working and all BUT I have a problem, when I try to resize a sprite which texture was made through the parsing, it ends up making this weird fading on the edges, I tried pretty much everything as setting the filtering mode or wrapping but nothing seems to be working, also I recently tried BufferedContainer but still did nothing, I am using a TextureRegion to define the texture from the spritesheet, I would love some alternatives or answers to why this happens

without any visuals to go by, it sounds like the corner pixels of each of your sprites in the spritesheet are sampling nearby transparent pixels due to a min/mag filter. you might get better results by setting the texture filtering mode to nearest (on your TextureStore), or by filling in nearby pixels with the expected edge colour.

again, hard to say without further details.

My bad, I didn't have any visual at the moment when I was writing the post

(using BufferedContainer)

(using scaling)

I'll look into what you suggested rq, thanks!

Rather than changing the filter mode to nearest, you likely want to use ClampToEdge

osu-framework/osu.Framework/Graphics/Textures/WrapMode.cs

Lines 13 to 16 in 004fae4

	/// <summary>
	/// Clamps to the edge of the texture, repeating the edge to fill the remainder of the draw area.
	/// </summary>
	ClampToEdge = 1,

E.g. TextureStore.Get(..., WrapMode.ClampToEdge, WrapMode.ClampToEdge)

it still happens even when setting the wrap mode to ClampToEdge

Alright so after messing around a lil bit more with BufferedContainers, I found out that setting the FrameBuffer Y Scale to 0 fixes the texture fading

FrameBuffer Scale Y 1

FrameBuffer Scale Y 0

I guess it works because the sprite doesn't find any nearby transparent pixels available on such a small texture size, anyways thanks for the help guys!

Oh. Using buffered containers is a bit of an important detail. We haven't really paid much attention to those being filtered pixel-perfectly yet, but I'll just say that using a 0x scale sounds like a jank solution and I'd hope that we can do this better in the future. I have nothing better so if it works then I can't argue against that solution, though! 😄

Yeah I was suprised that using a 0x scale would fix my issue, I feel like there should be another way of fixing it, but if it works I might just stay like this, I haven't really noticed any performance drops when moving to a BufferedContainer, everything is pretty fast, keep up the great job guys! I really like to see how the framework keeps improving everyday 🔥
