VkSamplerReductionMode

Reduction modes are specified by VkSamplerReductionMode, which takes values:

typedef enum VkSamplerReductionMode {
    VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE = 0,
    VK_SAMPLER_REDUCTION_MODE_MIN = 1,
    VK_SAMPLER_REDUCTION_MODE_MAX = 2,
} VkSamplerReductionMode;

pub struct SamplerReductionMode(u32);
impl SamplerReductionMode {
    pub const WEIGHTED_AVERAGE: Self = 0;
    pub const MIN: Self = 1;
    pub const MAX: Self = 2;
}

#define VkSamplerReductionModeEXT VkSamplerReductionMode

const SamplerReductionModeEXT: _ = vk::SamplerReductionMode;

• VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE specifies that texel values are combined by computing a weighted average of values in the footprint, using weights as specified in the image operations chapter.
• VK_SAMPLER_REDUCTION_MODE_MIN specifies that texel values are combined by taking the component-wise minimum of values in the footprint with non-zero weights.
• VK_SAMPLER_REDUCTION_MODE_MAX specifies that texel values are combined by taking the component-wise maximum of values in the footprint with non-zero weights.
• VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE_RANGECLAMP_QCOM specifies values are combined as described by VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE, followed by a texel range clamp.
