SDL_GetTextureProperties

Get the properties associated with a texture.

Header File

SDL_PropertiesID SDL_GetTextureProperties(SDL_Texture *texture);

texture

the texture to query

Returns a valid property ID on success or 0 on failure; call SDL_GetError() for more information.

The following read-only properties are provided by SDL:

SDL_PROP_TEXTURE_COLORSPACE_NUMBER: an SDL_ColorSpace value describing the colorspace used by the texture
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_POINTER: the VkImage associated with the texture
SDL_PROP_TEXTURE_VULKAN_TEXTURE_U_POINTER: the VkImage associated with the U plane of a YUV texture
SDL_PROP_TEXTURE_VULKAN_TEXTURE_V_POINTER: the VkImage associated with the V plane of a YUV texture
SDL_PROP_TEXTURE_VULKAN_TEXTURE_UV_POINTER: the VkImage associated with the UV plane of a NV12/NV21 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)

With the vulkan renderer:

SDL_PROP_TEXTURE_VULKAN_TEXTURE_NUMBER: the VkImage associated with the texture
