| | | | | | | | | | | | | | | | | | | 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.
* Added a helper function SDL_LockTextureToSurface()Sylvain Becker2019-09-301-0/+21

| | | | | | 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.

* Fixed bug 3345 - SDL_RenderClear inconsistency with ClipRectSam Lantinga2016-10-011-1/+2
| | | | | | | | | | | | | | | | 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.

* Render: Allow empty cliprect.J?rgen P. Tjern?2014-04-191-0/+10
| | | | | | | | | | | | 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

* When the window is resized, the viewport is automatically reset.Sam Lantinga2013-05-291-2/+1
| | | | | | This resolves lots of confusion around resizable windows. Most people don't expect a viewport to be implicitly set when the renderer is created and then not to be reset to the window size if the window is resized. Added common test command line parameters --logical WxH and --scale N to test the render logical size and scaling APIs.
