Ryan C. Gordon f8c1fc49 2021-07-14T14:15:30 doxygen: Fix all the "\returns" so they work as part of complete sentences.
Ryan C. Gordon 3f40396d 2021-03-21T14:18:39 First shot at merging the wiki documentation into the headers.
Sylvain Becker be4cfd51 2021-01-05T11:56:22 Add SDL_UpdateNVTexture() to update NV12/21 Texture (bug #5430) for renderer software, opengl, and opengles2
Sam Lantinga 9130f7c3 2021-01-02T10:25:38 Updated copyright for 2021
Sam Lantinga 611403dd 2020-03-08T21:02:40 Clarified that the clip rectangle is defined relative to the viewport, and added a clip test to testviewport.c

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.
Sylvain Becker 1ae61f10 2019-09-30T20:58:44 Added a helper function SDL_LockTextureToSurface() Similar to SDL_LockTexture(), except the locked area is exposed as a SDL surface.

Ryan C. Gordon 8340b0f0 2018-10-23T01:34:03 render: Add floating point versions of various draw APIs.
Ryan C. Gordon 1ecf4dfc 2018-10-04T16:34:44 render: Added SDL_RenderFlush().
Sam Lantinga e3cc5b2c 2018-01-03T10:03:25 Updated copyright for 2018
Sam Lantinga cf3d4503 2017-12-08T14:30:10 Added SDL_RenderGetMetalLayer() and SDL_RenderGetMetalCommandEncoder()
Sam Lantinga 2862b146 2017-08-12T13:05:26 Note that texture contents are undefined when the texture is created.
Sam Lantinga b3589ed6 2017-08-11T13:24:18 Fixed bug 3492 - SDL_RenderCopyEx angle direction not documented xyzdragon Reading https://wiki.libsdl.org/SDL_RenderCopyEx there is no mention what the angle means. Normally in a mathematically environment positive angles translate to counter-clockwise rotations, but in SDL positive angles means clockwise rotation.
Sam Lantinga d0b46f1b 2017-08-10T11:57:19 Fixed bug 3681 - SDL_UpateTexture documentation not specific enough about format requirement Simon Hug The documentation of SDL_UpateTexture does not say that the pixel data has to be in the format of the texture.
Sam Lantinga 45b774e3 2017-01-01T18:33:28 Updated copyright for 2017
Sam Lantinga 36156335 2016-11-20T21:34:54 Renaming of guard header names to quiet -Wreserved-id-macro Patch contributed by Sylvain
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.

Sam Lantinga 42065e78 2016-01-02T10:10:34 Updated copyright to 2016
Alex Szpakowski 4aae0290 2015-12-31T21:16:43 Updated some header comments and iOS documentation to better clarify high-dpi / retina support and screen-coordinate sizes versus pixel sizes.
Philipp Wiesemann 83e94e25 2015-08-21T23:50:59 Corrected documentation of the SDL_CreateTexture() functions in header file.
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().

Ryan C. Gordon b72938c8 2015-04-20T12:22:44 Windows: Always set the system timer resolution to 1ms by default. An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944.
Alex Szpakowski fe6c797c 2015-04-10T23:30:31 Fixed an iOS view orientation issue when SDL_GL_CreateContext or SDL_CreateRenderer is called.
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 0781b5f9 2015-01-30T23:20:15 Fix typos in header file documentation comments.
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. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!
Sam Lantinga 48481c8e 2014-11-29T11:18:49 Improved the pitch variable description
Philipp Wiesemann 9c398852 2014-11-22T22:20:40 Corrected header file documentation comment.
Philipp Wiesemann 3d2ca92e 2014-10-27T12:53:47 Fixed two typos in header file comment.
Pierre-Loup A. Griffais 24c86b55 2014-09-11T19:24:42 [X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam
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
David Ludwig 3dcb451f 2014-04-09T21:29:19 Added a README file regarding WinRT support To note, this file is currently formatted with CRLF line endings, rather than LF, to allow the file to be viewed with Notepad.
Sam Lantinga 58edac3e 2014-02-02T00:53:27 Fixed bug 2374 - Update copyright for 2014... Is it that time already??
Gabriel Jacobo f848adff 2013-11-29T10:06:08 Improve Android pause/resume behavior.
Ryan C. Gordon e9af6dcd 2013-11-23T15:52:49 Fixed a few public APIs that we accidentally neglected to mark as SDLCALL. Fixes Bugzilla #2262.
Sam Lantinga 57bd5147 2013-09-28T14:06:47 Added optimized YUV texture upload path with SDL_UpdateYUVTexture()
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.
Sam Lantinga 1ad936eb 2013-08-11T19:56:43 Fixed bug 2027 - Full-screen appears to be broken - hang in SDL_DestroyWindow() Rainer Deyke I'm running Linux Mint 15 with the Cinnamon window manager. SDL_DestroyWindow consistently locks up for me when the window if fullscreen.
