NAME¶

SDL_GetRendererProperties - Get the properties associated with a renderer.

SYNOPSIS¶

#include "SDL3/SDL.h"

SDL_PropertiesID SDL_GetRendererProperties(SDL_Renderer *renderer);

DESCRIPTION¶

The following read-only properties are provided by SDL:

• SDL_PROP_RENDERER_NAME_STRING : the
name of the rendering driver

• SDL_PROP_RENDERER_WINDOW_POINTER :
the window where rendering is displayed, if any

• SDL_PROP_RENDERER_SURFACE_POINTER :
the surface where rendering is displayed, if this is a software renderer
without a window

• SDL_PROP_RENDERER_OUTPUT_COLORSPACE_NUMBER :
an SDL_ColorSpace
value describing the colorspace for
output to the display, defaults to

SDL_COLORSPACE_SRGB .

• SDL_PROP_RENDERER_HDR_ENABLED_BOOLEAN :
true if the output colorspace is

SDL_COLORSPACE_SRGB_LINEAR
and the renderer
is showing on a display with HDR enabled. This property can change
dynamically when

SDL_EVENT_DISPLAY_HDR_STATE_CHANGED

is sent.

• SDL_PROP_RENDERER_SDR_WHITE_POINT_FLOAT :
the value of SDR white in the

SDL_COLORSPACE_SRGB_LINEAR
colorspace. When
HDR is enabled, this value is automatically multiplied into the color
scale. This property can change dynamically when

SDL_EVENT_DISPLAY_HDR_STATE_CHANGED

is sent.

• SDL_PROP_RENDERER_HDR_HEADROOM_FLOAT :
the additional high dynamic range that can be displayed, in terms of the
SDR white point. When HDR is not enabled, this will be 1.0. This property
can change dynamically when

SDL_EVENT_DISPLAY_HDR_STATE_CHANGED

is sent.

With the direct3d renderer:

• SDL_PROP_RENDERER_D3D9_DEVICE_POINTER :
the IDirect3DDevice9 associated with the renderer

With the direct3d11 renderer:

• SDL_PROP_RENDERER_D3D11_DEVICE_POINTER :
the ID3D11Device associated with the renderer

With the direct3d12 renderer:

• SDL_PROP_RENDERER_D3D12_DEVICE_POINTER :
the ID3D12Device associated with the renderer

• SDL_PROP_RENDERER_D3D12_COMMAND_QUEUE_POINTER :
the ID3D12CommandQueue associated with the renderer

With the vulkan renderer:

• SDL_PROP_RENDERER_VULKAN_INSTANCE_POINTER :
the VkInstance associated with the renderer

• SDL_PROP_RENDERER_VULKAN_SURFACE_NUMBER :
the VkSurfaceKHR associated with the renderer

• SDL_PROP_RENDERER_VULKAN_PHYSICAL_DEVICE_POINTER :
the VkPhysicalDevice associated with the renderer

• SDL_PROP_RENDERER_VULKAN_DEVICE_POINTER :
the VkDevice associated with the renderer

• SDL_PROP_RENDERER_VULKAN_GRAPHICS_QUEUE_FAMILY_INDEX_NUMBER :
the queue family index used for rendering

• SDL_PROP_RENDERER_VULKAN_PRESENT_QUEUE_FAMILY_INDEX_NUMBER :
the queue family index used for presentation

• SDL_PROP_RENDERER_VULKAN_SWAPCHAIN_IMAGE_COUNT_NUMBER :
the number of swapchain images, or potential frames in flight, used by
the Vulkan renderer
