Struct screen_13::driver::physical_device::SamplerFilterMinmaxProperties

pub struct SamplerFilterMinmaxProperties {
    pub image_component_mapping: bool,
    pub single_component_formats: bool,
}

Properties of the physical device for min/max sampler filtering.

See VkPhysicalDeviceSamplerFilterMinmaxProperties

Fields

image_component_mapping: bool

When false the component mapping of the image view used with min/max filtering must have been created with the r component set to the identity swizzle. Only the r component of the sampled image value is defined and the other component values are undefined.

When true this restriction does not apply and image component mapping works as normal.

single_component_formats: bool

When true the following formats support the VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_MINMAX_BIT feature with VK_IMAGE_TILING_OPTIMAL, if they support VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT:

• vk::Format::R8_UNORM
• vk::Format::R8_SNORM
• vk::Format::R16_UNORM
• vk::Format::R16_SNORM
• vk::Format::R16_SFLOAT
• vk::Format::R32_SFLOAT
• vk::Format::D16_UNORM
• vk::Format::X8_D24_UNORM_PACK32
• vk::Format::D32_SFLOAT
• vk::Format::D16_UNORM_S8_UINT
• vk::Format::D24_UNORM_S8_UINT
• vk::Format::D32_SFLOAT_S8_UINT

If the format is a depth/stencil format, this bit only specifies that the depth aspect (not the stencil aspect) of an image of this format supports min/max filtering, and that min/max filtering of the depth aspect is supported when depth compare is disabled in the sampler.
