Pierre Wendling d0bbfdbf 2022-12-01T16:07:03 Clang-Tidy fixes (#6725) (cherry picked from commit 3c501b963dd8f0605a6ce7978882df39ba76f9cd)
Sam Lantinga b8d85c69 2022-11-30T12:51:59 Update for SDL3 coding style (#6717) I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base. In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted. The script I ran for the src directory is added as build-scripts/clang-format-src.sh This fixes: #6592 #6593 #6594 (cherry picked from commit 5750bcb174300011b91d1de20edb288fcca70f8c)

Pierre Wendling 5b9608e0 2022-10-11T23:35:33 Remove D3D9 workarounds for Watcom. The linked PRs have been merged since May.
Sam Lantinga d744aafb 2022-09-15T01:00:12 Added support for simulated vsync in the renderer This kicks in if the platform doesn't support vsync directly, or if the present fails for some reason (e.g. minimized on some platforms) Fixes https://github.com/libsdl-org/SDL/issues/5134
Noel Berry 00452e47 2022-08-24T11:25:13 Adding SDL_GetWindowSizeInPixels for window size in pixels (#6112)

Sam Lantinga adc68758 2022-06-17T10:22:28 Added SDL_copyp to avoid size mismatch when copying values (thanks @1bsyl!) Closes https://github.com/libsdl-org/SDL/pull/5811
Eric Wasylishen ab81a559 2022-06-07T02:01:27 Windows DPI scaling/highdpi support Adds hint "SDL_WINDOWS_DPI_SCALING" which can be set to "1" to change the SDL coordinate system units to be DPI-scaled points, rather than pixels everywhere. This means windows will be appropriately sized, even when created on high-DPI displays with scaling. e.g. requesting a 640x480 window from SDL, on a display with 125% scaling in Windows display settings, will create a window with an 800x600 client area (in pixels). Setting this to "1" implicitly requests process DPI awareness (setting SDL_WINDOWS_DPI_AWARENESS is unnecessary), and forces SDL_WINDOW_ALLOW_HIGHDPI on all windows.

Sylvain ab758398 2021-09-20T16:53:03 Direct3D: remove RenderCopy and RenderCopyEx from back-end
Ryan C. Gordon 114d1d46 2021-09-27T23:18:25 direct3d: Remove unnecessary render target support check. Direct3D 9 dictates that caps.NumSimultaneousRTs must always be at least 1, which is to say that Direct3D 9 level hardware must always support render targets. (caps.NumSimultaneousRTs is meant to show if you can draw to multiple render targets in a single draw call.) We had already hardcoded SDL_RENDERER_TARGETTEXTURE as available earlier in the function anyhow. Fixes #4781.
Misa 4549769d 2021-03-07T15:20:45 Add `SDL_RenderSetVSync()` Currently, if an application wants to toggle VSync, they'd have to tear down the renderer and recreate it. This patch fixes that by letting applications call SDL_RenderSetVSync(). This is the same as the patch in #3673, except it applies to all renderers (including PSP, even thought it seems that the VSync flag is disabled for that renderer). Furthermore, the renderer flags also change as well, which #3673 didn't do. It is also an API instead of using hint callbacks (which could be potentially dangerous). Closes #3673.

Ryan C. Gordon 5fc13fcb 2021-08-04T07:00:17 direct3d: Commit viewport state before clearing, attempt 2. This reintroduces the fix from 0e16ee8330606603, but just marks the viewport state as dirty after a clear that needs to expand the viewport to fill the render target, as we'll need to also reset the orthographic projection state elsewhere, and that won't happen if we clear the dirty flag here. Fixes #4210. (again.) (...sorry...!)
Sam Lantinga 9d64e6b4 2021-08-03T00:29:33 Revert "direct3d: Commit dirty viewport state before clearing." This reverts commit 0e16ee833060660318cc324cf99c9736f4d48499.
Ryan C. Gordon 0e16ee83 2021-08-03T02:07:47 direct3d: Commit dirty viewport state before clearing. Otherwise you might have set the viewport to the full size of the render target in SDL's API but this change hasn't been transmitted to Direct3D yet by the time we attempt to clear. Fixes #4210.
Ryan C. Gordon 585c11c5 2021-07-30T00:33:15 direct3d: Fix possibly-incorrect scissor test when clearing. Thanks to @JayFoxRox who did the detective work on this! Fixes #3357.

Sam Lantinga cb361896 2020-12-09T07:16:22 Fixed bug 5235 - All internal sources should include SDL_assert.h Ryan C. Gordon We should really stick this in SDL_internal.h or something so it's always available.
Sam Lantinga b6afbe63 2020-04-07T09:38:57 Added SDL_log.h to SDL_internal.h so logging is available everywhere
Sam Lantinga c8c05a9f 2020-03-08T19:23:21 Fixed bug 4991 - Pixel shader problem when recreating a texture for direct3d renderer cmediaplayer Hi, i already mentioned in the SDL discourse a bug that recreating of a texture occours pixel shader problem on direct3d renderer. There is no problem for direct3d11. You can see the issue by using my app named C Media Player which is available for Windows for free using my web site www.cmediaplayer.com. Just follow the steps: *Open a media file *When playing the file change the scale quality under the video menu. *You will see the problem.

Sam Lantinga 5e19e66c 2019-12-22T13:39:44 Fixed bug 4914 - Expose SDL_ScaleMode and add SDL_SetTextureScaleMode/SDL_GetTextureScaleMode Konrad This was something rather trivial to add, but asked at least several times before (I did google about it as well). It should be possible to dynamically change scaling mode of the texture. It is actually trivial task, but until now it was only possible with a hint before creating a texture. I needed it for my game as well, so I took the liberty of writing it myself. This patch adds following functions: SDL_SetTextureScaleMode(SDL_Texture * texture, SDL_ScaleMode scaleMode); SDL_GetTextureScaleMode(SDL_Texture * texture, SDL_ScaleMode *scaleMode); That way you can change texture scaling on the fly.
Ryan C. Gordon 847bd8d9 2019-09-02T00:11:58 direct3d: Be more aggressive about resetting state when textures go away. Fixes Bugzilla #4768.

Cameron Gutman e681623c 2019-06-20T19:51:00 direct3d: Fix dirty textures failing to update Even if the texture itself has not changed since last time, the data may have so we must call UpdateDirtyTexture() to handle that possibility.

Ryan C. Gordon fcb46813 2018-10-01T13:41:15 render: D3D9 doesn't need to check for stream offset support anymore. We don't use offsets at all now. Too slow.
Ryan C. Gordon 709f5ee4 2018-10-01T11:32:08 render: Set the D3D9 stream source once and choose offsets during draw calls. This is _much_ faster than setting the offsets with SetStreamSource!

Ryan C. Gordon 5e644cfd 2018-10-01T01:23:02 render: first shot at moving Direct3D 9 backend to new interface. Untested!
Sam Lantinga eb14b635 2018-05-07T19:52:25 Fixed bug 4134 - Render targets lose scale quality after minimizing a fullscreen window Olli-Samuli Lehmus If one creates a window with the SDL_WINDOW_FULLSCREEN_DESKTOP flag, and creates a render target with SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "linear"), and afterwards sets SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "nearest"), after minimizing the window, the scale quality hint is lost on the render target. Textures however do keep their interpolation modes.

Sam Lantinga cac4e312 2017-12-08T11:34:32 Added check for failure of D3D_ActivateRenderer()
Sam Lantinga 1a1cd8c1 2017-12-08T11:09:05 Fixed bug 1878 - Scaled texture draws with filtering produce wrapping artifacts. Yuri K. Schlesner When using texture filtering, there are filtering artifacts visible on the edges of scaled textures, where the texture filtering pulls in texels from the other side of the texture. Using clamping texture modes wouldn't completely fix this since source rectangles don't need to cover the whole texture. (See screenshot attached in next post.) The opengl driver uses clamping on textures and so avoid this at least in the cases where the source rect is the whole texture. The direct3d driver does not and so has problems in every case. I'm not sure if it can actually completely be fixed, but at least enabling clamping for direct3d would be one step in the right direction.
Sam Lantinga a6a4e27a 2017-11-12T22:51:12 Updated SDL's YUV support, many thanks to Adrien Descamps New functions get and set the YUV colorspace conversion mode: SDL_SetYUVConversionMode() SDL_GetYUVConversionMode() SDL_GetYUVConversionModeForResolution() SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats. Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.
Sam Lantinga 30d554e3 2017-08-19T03:07:44 Fixed building SDL applications with Visual Studio and the clang toolset Also fixed building 64-bit SDL with clang. 32-bit doesn't build because of the inline assembly for C runtime support.
Sam Lantinga c59d9923 2017-08-14T05:51:44 Implemented more flexible blending modes for accelerated renderers This fixes bug 2594 - Propose new blend mode, SDL_BLENDMODE_BLEND_DSTA blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_SRC_ALPHA, SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA, SDL_BLENDOPERATION_ADD, SDL_BLENDFACTOR_ZERO, SDL_BLENDFACTOR_ONE, SDL_BLENDOPERATION_ADD); This fixes bug 2828 - Subtractive Blending blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_SRC_ALPHA, SDL_BLENDFACTOR_ONE, SDL_BLENDOPERATION_SUBTRACT, SDL_BLENDFACTOR_ZERO, SDL_BLENDFACTOR_ONE, SDL_BLENDOPERATION_SUBTRACT); This goes partway to fixing bug 3684 - Add support for a pre-multiplied alpha blending mode blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_ONE, SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA, SDL_BLENDOPERATION_ADD, SDL_BLENDFACTOR_ONE, SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA, SDL_BLENDOPERATION_ADD);

Sam Lantinga 77305d47 2016-10-01T11:46:32 Fixed bug 3345 - SDL_RenderClear inconsistency with ClipRect Simon Hug The description of the SDL_RenderClear function in the SDL_render.h header says the following: "This function clears the entire rendering target, ignoring the viewport." The word "entire" implies that the clipping rectangle set with SDL_RenderSetClipRect also gets ignored. This is left somewhat ambiguous if only the viewport is mentioned. Minor thing, but let's see what the implementations actually do. The software renderer ignores the clipping rectangle when clearing. It even has a comment on this: /* By definition the clear ignores the clip rect */ Most other render drivers (opengl, opengles, opengles2, direct3d, and psp [I assume. Can't test it.]) use the scissor test for the ClipRect and don't disable it when clearing. Clearing will only happen within the clipping rectangle for these drivers. An exception is direct3d11 which uses a clear function that ignores the scissor test.
David Ludwig 23af328b 2016-06-24T22:17:56 Fixed Bug 3147 - Windows: Crash when resizing Window since hg 1f9d57965528 Thanks for the fix, Gab!

Philipp Wiesemann 0e45984f 2015-06-21T17:33:46 Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().
Sam Lantinga 38549a7b 2015-06-04T00:56:11 Fixed bug 2625 - Direct3D9 with SDL_TEXTUREACCESS_TARGET textures causes an application crash Roberto I have debugged the code checking the function calls when Direct3D is the renderer, remember that with software and OpenGL renderers, this issue is not happening. - Create the texture: SDL_Texture *pTex = SDL_CreateTexture(pRenderer, iFormat, SDL_TEXTUREACCESS_TARGET, pSurf->w, pSurf->h); - Update the texture: SDL_UpdateTexture(pTex, NULL, pSurf->pixels, pSurf->pitch); SDL_render.c, SDL_UpdateTexture(): return renderer->UpdateTexture(renderer, texture, rect, pixels, pitch); SDL_render_d3d.c, D3D_UpdateTexture(): if (D3D_UpdateTextureRep(data->device, &texturedata->texture, texture->format, rect->x, rect->y, rect->w, rect->h, pixels, pitch) < 0) { SDL_render_d3d.c, D3D_UpdateTextureRep(): if (D3D_CreateStagingTexture(device, texture) < 0) { SDL_render_d3d.c, D3D_CreateStagingTexture(): result = IDirect3DDevice9_CreateTexture(..., D3DPOOL_SYSTEMMEM, ...) --> FAIL! with INVALIDCALL code After checking a bit the Microsoft documentation, I found this: D3DUSAGE_RENDERTARGET can only be used with D3DPOOL_DEFAULT. (https://msdn.microsoft.com/en-us/library/windows/desktop/bb172625%28v=vs.85%29.aspx) The call that fails, is using D3DUSAGE_RENDERTARGET with D3DPOOL_SYSTEMMEM which is unsupported, hence the INVALIDCALL return code.

Edward Rudd b88ca1b4 2015-02-10T16:28:56 the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
Philipp Wiesemann b48e54aa 2015-01-26T22:00:29 Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
David Ludwig 70438be2 2014-12-03T10:55:23 WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file.
