       Defined in SDL3/SDL_render.h

SYNOPSIS

       #include "SDL3/SDL.h"

       SDL_PropertiesID SDL_GetTextureProperties(SDL_Texture *texture);

DESCRIPTION

       The following read-only properties are provided by SDL:

       • SDL_PROP_TEXTURE_COLORSPACE_NUMBER :
         an SDL_Colorspace
        value describing the texture
         colorspace.

       • SDL_PROP_TEXTURE_FORMAT_NUMBER : one
         of the enumerated values in SDL_PixelFormat .

       • SDL_PROP_TEXTURE_ACCESS_NUMBER : one
         of the enumerated values in SDL_TextureAccess .

       • SDL_PROP_TEXTURE_WIDTH_NUMBER : the
         width of the texture in pixels.

       • SDL_PROP_TEXTURE_HEIGHT_NUMBER : the
         height of the texture in pixels.

       • SDL_PROP_TEXTURE_SDR_WHITE_POINT_FLOAT :
         for HDR10 and floating point textures, this defines the value of 100%
         diffuse white, with higher values being displayed in the High Dynamic
         Range headroom. This defaults to 100 for HDR10 textures and 1.0 for other
         textures.

       • SDL_PROP_TEXTURE_HDR_HEADROOM_FLOAT :
         for HDR10 and floating point textures, this defines the maximum dynamic
         range used by the content, in terms of the SDR white point. If this is
         defined, any values outside the range supported by the display will be
         scaled into the available HDR headroom, otherwise they are clipped. This
         defaults to 1.0 for SDR textures, 4.0 for HDR10 textures, and no default
         for floating point textures.

       With the direct3d11 renderer:

       • SDL_PROP_TEXTURE_D3D11_TEXTURE_POINTER :
         the ID3D11Texture2D associated with the texture

       • SDL_PROP_TEXTURE_D3D11_TEXTURE_U_POINTER :
         the ID3D11Texture2D associated with the U plane of a YUV texture

       • SDL_PROP_TEXTURE_D3D11_TEXTURE_V_POINTER :
         the ID3D11Texture2D associated with the V plane of a YUV texture

       With the direct3d12 renderer:

       • SDL_PROP_TEXTURE_D3D12_TEXTURE_POINTER :
         the ID3D12Resource associated with the texture

       • SDL_PROP_TEXTURE_D3D12_TEXTURE_U_POINTER :
         the ID3D12Resource associated with the U plane of a YUV texture

       • SDL_PROP_TEXTURE_D3D12_TEXTURE_V_POINTER :
         the ID3D12Resource associated with the V plane of a YUV texture

       With the vulkan renderer:

       • SDL_PROP_TEXTURE_VULKAN_TEXTURE_NUMBER :
         the VkImage associated with the texture

       With the opengl renderer:

       • SDL_PROP_TEXTURE_OPENGL_TEXTURE_NUMBER :
         the GLuint texture associated with the texture

       • SDL_PROP_TEXTURE_OPENGL_TEXTURE_UV_NUMBER :
         the GLuint texture associated with the UV plane of an NV12 texture

       • SDL_PROP_TEXTURE_OPENGL_TEXTURE_U_NUMBER :
         the GLuint texture associated with the U plane of a YUV texture

       • SDL_PROP_TEXTURE_OPENGL_TEXTURE_V_NUMBER :
         the GLuint texture associated with the V plane of a YUV texture

       • SDL_PROP_TEXTURE_OPENGL_TEXTURE_TARGET_NUMBER :
         the GLenum for the texture target ( GL_TEXTURE_2D , GL_TEXTURE_RECTANGLE_ARB , etc)

       • SDL_PROP_TEXTURE_OPENGL_TEX_W_FLOAT :
         the texture coordinate width of the texture (0.0 - 1.0)

       • SDL_PROP_TEXTURE_OPENGL_TEX_H_FLOAT :
         the texture coordinate height of the texture (0.0 - 1.0)

       With the opengles2 renderer:

       • SDL_PROP_TEXTURE_OPENGLES2_TEXTURE_NUMBER :
         the GLuint texture associated with the texture

       • SDL_PROP_TEXTURE_OPENGLES2_TEXTURE_UV_NUMBER :
         the GLuint texture associated with the UV plane of an NV12 texture

       • SDL_PROP_TEXTURE_OPENGLES2_TEXTURE_U_NUMBER :
         the GLuint texture associated with the U plane of a YUV texture

       • SDL_PROP_TEXTURE_OPENGLES2_TEXTURE_V_NUMBER :
         the GLuint texture associated with the V plane of a YUV texture

       • SDL_PROP_TEXTURE_OPENGLES2_TEXTURE_TARGET_NUMBER :
         the GLenum for the texture target ( GL_TEXTURE_2D , GL_TEXTURE_EXTERNAL_OES , etc)
