Options for each frame.

Fields

clear_history: bool

Whether or not to clear the history buffers.

frame_direction: i32

The direction of rendering. -1 indicates that the frames are played in reverse order.

rotation: u32

The rotation of the output. 0 = 0deg, 1 = 90deg, 2 = 180deg, 3 = 270deg.

total_subframes: u32

The total number of subframes ran. Default is 1.

current_subframe: u32

The current sub frame. Default is 1.

aspect_ratio: f32

The expected aspect ratio of the source image.

This can differ from the actual aspect ratio of the source image.

The default is 0 which will automatically infer the ratio from the source image.

frames_per_second: f32

The original frames per second of the source. Default is 1.

frametime_delta: u32

Time in milliseconds between the current and previous frame. Default is 0.

color_space: __ColorSpace

Target color space bound to the shader HDRMode uniform. Must match the host swapchain color space. Default is ColorSpace::Sdr.

brightness_nits: f32

HDR SDR reference white in nits, bound to the shader BrightnessNits uniform. Default is 200.0. Only meaningful when the chain’s HDR mode is non-zero.

expand_gamut: u32

Gamut expansion mode bound to the shader ExpandGamut uniform. Default is 0.

gyroscope: [f32; 3]

Bound to the shader Gyroscope (vec3) uniform. Default is [0, 0, 0].

accelerometer: [f32; 3]

Bound to the shader Accelerometer (vec3) uniform. Default is [0, 0, 0].

accelerometer_rest: [f32; 3]

Bound to the shader AccelerometerRest (vec3) uniform. Default is [0, 0, 0].
