Eric Wasylishen 76392f4f 2023-01-11T19:45:01 Handle DPI scaling in SDL_GetWindowSurface Fixes DPI awareness of testdrawchessboard (previously, the surface was being created in points instead of pixels, resulting in the demo app only drawing in a corner of the screen on High-DPI displays) *_CreateWindowFramebuffer()/*_UpdateWindowFramebuffer(): are updated to use SDL_GetWindowSizeInPixels instead of SDL_GetWindowSize() or window->w/window->h. Most of the _CreateWindowFramebuffer backends are untested except for Windows. Fixes #7047 (cherry picked from commit 67c91353e01f6f2c0cc80c17eeddbad6def7cb01)

Pierre Wendling d0bbfdbf 2022-12-01T16:07:03 Clang-Tidy fixes (#6725) (cherry picked from commit 3c501b963dd8f0605a6ce7978882df39ba76f9cd)
Sam Lantinga 6926d046 2022-11-30T13:05:57 Fixed build after cherry-pick of 5750bcb174300011b91d1de20edb288fcca70f8c from SDL3
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)

ulatekh ec58a817 2022-10-05T19:26:09 Fixes made in response to running a static code analyzer under MS Windows. Most of these are probably harmless, but the changes to SDL_immdevice.c and SDL_pixels.c appear to have fixed genuine bugs. SDL_audiocvt.c: By separating the calculation of the divisor, I got rid of the suspicion that dividing a double by an integer led to loss of precision. SDL_immdevice.c: Added a missing test, one that could have otherwise led to dereferencing a null pointer. SDL_events.c, SDL_gamecontroller.c, SDL_joystick.c, SDL_malloc.c, SDL_video.c: Made it clear the return values weren't used. SDL_hidapi_shield.c: The size is zero, so nothing bad would have happened, but the SDL_memset() was still being given an address outside of the array's range. SDL_dinputjoystick.c: Initialize local data, just in case IDirectInputDevice8_GetProperty() isn't guaranteed to write to it. SDL_render_sw.c: drawstate.viewport could be null (as seen on line 691). SDL.c: SDL_MostSignificantBitIndex32() could return -1, though I don't know if you want to cope with that (what I did) or SDL_assert() that it can't happen. SDL_hints.c: Replaced boolean tests on pointer values with comparisons to NULL. SDL_pixels.c: Looks like the switch is genuinely missing a break! SDL_rect_impl.h: The MacOS static checker pointed out issues with the X comparisons that were handled by assertions; I added assertions for the Y comparisons. SDL_yuv.c, SDL_windowskeyboard.c, SDL_windowswindow.c: Checked error-result returns.
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

Sam Lantinga 981e0d36 2020-01-16T08:52:59 Fixed bug 4903 - Lack of color multiply with alpha (SDL_BLENDMODE_MOD + SDL_BLENDMODE_BLEND) blending mode for all renderers Konrad This kind of blending is rather quite useful and in my opinion should be available for all renderers. I do need it myself, but since I didn't want to use a custom blending mode which is supported only by certain renderers (e.g. not in software which is quite important for me) I did write implementation of SDL_BLENDMODE_MUL for all renderers altogether. SDL_BLENDMODE_MUL implements following equation: dstRGB = (srcRGB * dstRGB) + (dstRGB * (1-srcA)) dstA = (srcA * dstA) + (dstA * (1-srcA)) Background: https://i.imgur.com/UsYhydP.png Blended texture: https://i.imgur.com/0juXQcV.png Result for SDL_BLENDMODE_MOD: https://i.imgur.com/wgNSgUl.png Result for SDL_BLENDMODE_MUL: https://i.imgur.com/Veokzim.png I think I did cover all possibilities within included patch, but I didn't write any tests for SDL_BLENDMODE_MUL, so it would be lovely if someone could do it.
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.
Sam Lantinga 5dcac4cc 2019-06-18T10:08:19 Fixed 4669 - Using the software SDL_Renderer on Android leads to GL errors & black screen when window resizes Sylvain I think what happening with the software renderer is: * you're somehow in background (so texture creation is not possible) * it resizes and wants to push a SDL_WINDOWEVENT_SIZE_CHANGED It call: https://hg.libsdl.org/SDL/file/a010811d40dd/src/render/SDL_render.c#l683 * GetOutputSize * SW_GetOutputSize * SW_ActivateRenderer * SDL_GetWindowSurface * SDL_CreateWindowFramebuffer which is mapped to SDL_CreateWindowTexture and it ends up re-creating the surface/a texture, while being in background

Sam Lantinga da56cefa 2018-10-30T07:00:03 Fixed bug 4188 - Software renderer SDL_RenderCopyEx blits corrupt image under certain cases Sylvain Re-opening this issue. It fixes the test-case, but it introduces a regression with another bug (bug #4313). So here's a new patch that activate cropping of the source surface to solve the issue. It also reverts the wrong changeset. It prevents unneeded colorkey error message.

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 ab8bd3d9 2016-11-15T01:12:27 Fixed bug 3359 - Software renderer does incorrect blending with SDL_RenderCopyEx Simon Hug The software renderer produces incorrect results when blending textures at an angle with certain blend modes. It seems that there were some edge cases that weren't considered when the SW_RenderCopyEx function was last changed. Or another bug possibly covered up the problem. (More on that in another bug report.) Most of the issues come from the fact that the rotating function sets a black colorkey. This is problematic because black is most likely appearing in the surface and the final blit will ignore these pixels. Unless a colorkey is already set (the software renderer currently never sets one), it's very hard to find a free color. Of course it could scan over the whole image until one is found, but that seems inefficient. The following blend modes have issues when drawn at an angle. NONE: The black pixels get ignored, making them essentially transparent. This breaks the 'dstRGBA = srcRGBA' definition of the NONE blend mode. MOD: Again, the black pixels get ignored. This also breaks the 'dstRGB = dstRGB * srcRGB' definition of the MOD blend mode, where black pixels would make the destination black as well. A white colorkey will work though, with some preparations. BLEND: There are some issues when blending a texture with a translucent RGBA target texture. I - uh - forgot what the problem here exactly is. This patch fixes the issues mentioned above. It mainly changes the code so it tries to do things without the colorkey and removes the automatic format conversion part from the SDLgfx_rotateSurface function. Getting the format right is something the caller has to do now and the required code has been added to the SW_RenderCopyEx function. There's a small change to the SW_CreateTexture function. RLE encoding a surface with an alpha mask can be a lossy process. Depending on how the user uses the RGBA channels, this may be undesired. The change that surfaces with an alpha mask don't get encoded makes the software renderer consistent with the other renderers. The SW_RenderCopyEx function now does these steps: Lock the source surface if necessary. Create a clone of the source by using the pixel buffer directly. Check the format and set a flag if a conversion is necessary. Check if scaling or cropping is necessary and set the flag for that as well. Check if color and alpha modulation has to be done before the rotate. Check if the source is an opaque surface. If not, it creates a mask surface that is necessary for the NONE blend mode. If any of the flags were set, a new surface is created and the source will be converted, scaled, cropped, and modulated. The rest of the function stays somewhat the same. The mask also needs to be rotated of course and then there is the NONE blend mode... It's surprisingly hard to get the pixel from a rotated surface to the destination buffer without affecting the pixel outside the rotated area. I found a way to do this with three blits which is pretty hard on the performance. Perhaps someone has an idea how to do this faster? As mentioned above, the SDLgfx_rotateSurface now only takes 8-bit paletted or 32-bit with alpha mask surfaces. It additionally sets the new surfaces up for the MOD blend mode. I shortly tested the 8-bit path of SDLgfx_rotateSurface and it seemed to work so far. This path is not used by the software renderer anyway.
Sam Lantinga 9c483655 2016-10-07T18:00:30 Fixed bug 3029 - software renderer cuts off edges when rotate-blitting with a multiple of 90 degrees Adam M. When doing a rotated texture copy with the software renderer, where the angle is a multiple of 90 degrees, one or two edges of the image get cut off. This is because of the following line in sw_rotate.c: if ((unsigned)dx < (unsigned)sw && (unsigned)dy < (unsigned)sh) { which is effectively saying: if (dx >= 0 && dx < src->w-1 && dy >= 0 && dy < src->h-1) { As a result, it doesn't process pixels in the right column or bottom row of the source image (except when they're accessed as part of the bilinear filtering for nearby pixels). This causes it to look like the edges are cut off, and it's especially obvious with an exact multiple of 90 degrees.

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 b7ede6cc 2015-06-19T23:20:43 Fixed bug 1550 - SDL_RenderCopy/CopyEx in software should optionally render 8bit alpha Adam M. There are three problems in the code that I see. 1. SW_RenderCopyEx enables a color key on surface_scaled even if the source surface didn't have a color key. 2. SW_RenderCopyEx doesn't copy blend mode, color mod, or alpha mod from src to surface_scaled. 3. When SDL_BlitScaled(src, srcrect, surface_scaled, &tmp_rect) is called, it blends the src pixels into surface_scaled instead of overwriting them (if src has blending, etc. enabled). I've attached a patch that 1) fixes the three problems that I mentioned, 2) adds the requested performance improvement of using the regular blit function if no rotation or flipping is needed, 3) avoids cloning the source surface if no stretching is required, and simplifies the rotation code slightly.

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

Sam Lantinga 5df11f8a 2014-06-21T21:46:42 Made SDL_PIXELFORMAT_ARGB8888 the default texture format for consistency across renderer implementations.
J?rgen P. Tjern? defd90b6 2014-04-19T13:15:41 Render: Allow empty cliprect. This fixes an issue where an empty cliprect is treated the same as a NULL cliprect, causing the render backends to disable clipping. Also adds a new API, SDL_RenderIsClipEnabled(render) that allows you to differentiate between: - SDL_RenderSetClipRect(render, NULL) - SDL_Rect r = {0,0,0,0}; SDL_RenderSetClipRect(render, &r); Fixes https://bugzilla.libsdl.org/show_bug.cgi?id=2504

Ryan C. Gordon 7e1289af 2013-11-24T23:56:17 Make internal SDL sources include SDL_internal.h instead of SDL_config.h The new header will include SDL_config.h, but allows for other global stuff.

Gabriel Jacobo dad42067 2013-08-12T11:13:50 Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
