Bug 2167

Summary: Allow specifying texture scale filter mode for each SDL_RenderCopy/SDL_RenderCopyEx call

Description Ellie 2013-10-20 15:37:10 UTC 
My engine is object-centered. Each object uses a texture, possibly shared with other objects. An object has various properties like position, scale, and texture filter mode (so it's possible to mix smoothly scaled and pixelated things).

Currently, it appears SDL handles the texture filter hint per texture/in the SDL_CreateTexture call (source: mailing list). This means I would need to create multiple versions of the same texture to be able to switch filter mode per object for objects sharing a texture. That seems like a uselessly complicated and memory-wasting solution.

Therefore, please provide a way to specify/change the texture scale filter for each single SDL_RenderCopy/SDL_RenderCopyEx call, the simplest solution being that the hint for texture scaling is re-evaluated for each of those calls.

I looked through the code, and this looks pretty easy to do.  I'll add this to the TODO list post 2.0.1
Comment 2 Sam Lantinga 2017-08-15 05:18:54 UTC 
Planning to add this for SDL 2.1

Sam, this bug report can me marked as resolved because some time ago my commit with SDL_SetTextureScaleMode and SDL_GetTextureScaleMode was merged into SDL. This can be done on the fly now.

Ah, very neat! Thanks <3
