Sam Lantinga 23e3cbec20 Only call clipboard callbacks with mime types they expect 
Also clarified that returning NULL from a callback sends zero length data to the receiver, which should be able to handle that.

Fixes https://github.com/libsdl-org/SDL/issues/10192
 2025-10-09 12:20:19 -07:00
Sam Lantinga 3c0a6c32d4 Fixed crash getting clipboard data processing clipboard events on X11 
SDL_PumpEvents() was freeing the temporary memory in the clipboard event, so if the application was iterating over the mime types in the event and retrieving the clipboard data, it would crash after the first entry.

Sam Lantinga 84b0565096 Fixed potential memory leak 2025-10-08 19:44:03 -07:00
Sam Lantinga 3316dde0c2 Improved error information when renderer creation fails 
On Android, if you create a window with SDL_WINDOW_OPENGL, you can't create a Vulkan surface. The error message has been improved to reflect this, and the error is propagated back up to the application.

Also added warn level logging if the renderer couldn't be created.

Sam Lantinga caa33cb018 Removed InvalidateRect() when moving and resizing 
This was added in 2016, presumably to help address the move/resize issues on Windows, which have been since been addressed by the live-resize functionality.

 2025-10-08 12:40:29 -07:00
Sam Lantinga 244ae39b30 Optimized the 16-bit -> 32-bit SSE pixel conversion 
Test code:
---
int main( int argc, char *argv[] )
{
    SDL_Surface *orig = SDL_LoadPNG("testyuv.png");
    SDL_Surface *surf16 = SDL_ConvertSurface(orig, SDL_PIXELFORMAT_RGB565);
    SDL_Surface *surf32 = SDL_ConvertSurface(surf16, SDL_PIXELFORMAT_ARGB8888);

    Uint64 then = SDL_GetTicks();
    for (int i = 0; i < 100000; ++i) {
        SDL_BlitSurface(surf16, NULL, surf32, NULL);
    }
    Uint64 now = SDL_GetTicks();
    SDL_Log("Blit took %d ms\n", (int)(now - then));
    return 0;
}
---

Results on my system:
BlitNtoN: Blit took 34522 ms
Blit_RGB565_32 (3 LUT): Blit took 9316 ms
Blit_RGB565_32 (1 LUT): Blit took 5268 ms
Blit_RGB565_32_SSE41: Blit took 1619 ms
 2025-10-07 16:31:14 -07:00
Sam Lantinga 168de63a7a Switched back to a single LUT for 16-bit -> 32-bit pixel conversion 
This beats the previous 3-LUT version and even beats SSE on my system.

Test code:
---
int main( int argc, char *argv[] )
{
    SDL_Surface *orig = SDL_LoadPNG("testyuv.png");
    SDL_Surface *surf16 = SDL_ConvertSurface(orig, SDL_PIXELFORMAT_RGB565);
    SDL_Surface *surf32 = SDL_ConvertSurface(surf16, SDL_PIXELFORMAT_ARGB8888);

    Uint64 then = SDL_GetTicks();
    for (int i = 0; i < 100000; ++i) {
        SDL_BlitSurface(surf16, NULL, surf32, NULL);
    }
    Uint64 now = SDL_GetTicks();
    SDL_Log("Blit took %d ms\n", (int)(now - then));
    return 0;
}
---

Results on my system:
BlitNtoN: Blit took 34522 ms
Blit_RGB565_32 (3 LUT): Blit took 9316 ms
Blit_RGB565_32 (1 LUT): Blit took 5268 ms
Blit_RGB565_32_SSE41: Blit took 6399 ms

Sam Lantinga dbd5dd8c75 Ensure 16-bit -> 32-bit conversion is consistent between blitters 
The SSE, LUT, and other blitters should have the same results for 16-bit -> 32-bit conversion

Sam Lantinga 49d51a0d3c Removed TEXTURETYPE_PALETTE_PIXELART 
This doesn't make any sense since the pixel art algorithm uses a box filter to get an average pixel value which isn't possible with indexed textures.

Sam Lantinga a864dcac25 Added support for using the GPU renderer as an offscreen renderer 
SDL_CreateGPURenderer() now allows passing in an existing GPU device and passing in a NULL window to create an offscreen renderer.

Also renamed SDL_SetRenderGPUState() to SDL_SetGPURenderState().

Full object validation was always done before this hint and there are a number of shipping products that relied on this, so don't change it by default.

Sam Lantinga 15f1cb4c98 Added GPU API support on visionOS 
You must set SDL_PROP_GPU_DEVICE_CREATE_FEATURE_DEPTH_CLAMPING_BOOLEAN to false on this platform, since setDepthClipMode is not supported on Apple headsets (as of visionOS 2.3) and clipping is the default.

Sam Lantinga 2a01e12d34 Simplify palette code 
Each texture gets its own palette, the palette is updated when it is rendered if necessary, rendering is flushed if a texture render is already queued up.

Trying to share palettes and handle the different cases of queued rendering and changing palettes in the middle of the frame ends up being very complicated, so we'll keep it simple for now.

Sam Lantinga b2188b325d Fixed HIDAPI controller disconnect reading on multiple threads 
If multiple threads are calling SDL_UpdateJoysticks(), then an overlapped read can be initiated on one thread (read_pending set to true) and GetOverlappedResult() called on another thread. This results in ERROR_OPERATION_ABORTED. This is harmless so we shouldn't return an error in this case, we'll just retry the read on the next call.
