testwm2: Fix video modes menu hit detection when highdpi or logical size used ()
* SDLTest_CommonDrawWindowInfo: log SDL_RenderGetScale, SDL_RenderGetLogicalSize

* testwm2: fix video modes menu hit detection in High DPI cases

- also when logical size is specified, e.g.
  `--logical 640x480 --resizable --allow-highdpi`

* add function to determine logical coordinates of renderer point when given window point

* change since to the targeted milestone

* fix typo

* rename for consistency

* Change logical coordinate type to float, since we can render with floating point precision.

* add function to convert logical to window coordinates

* testwm2: use new SDL_RenderWindowToLogical

* SDL_render.c: alternate SDL_RenderWindowToLogical/SDL_RenderLogicalToWindow

Misa 4a9947336c `SDL_RenderSetVSync()`: Restrict `vsync` to 0 or 1
In the future, we might want to support special swap intervals. To
prevent applications from expecting nonzero values of vsync to be the
same as "on", fail with SDL_Unsupported() if the value passed is neither
0 nor 1.

Misa 4549769d7d 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 , 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  didn't do. It is also an API instead of using hint
callbacks (which could be potentially dangerous).

Closes .

Sam Lantinga 5e19e66c73 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 b3589ed6a6 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 77305d47c2 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.

Philipp Wiesemann 83e94e257b Corrected documentation of the SDL_CreateTexture() functions in header file. 2015-08-21 23:50:59 +02:00
Philipp Wiesemann 0e45984fa0 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().
