C Specification

In addition to the predefined border color values, applications can provide a custom border color value by including the VkSamplerCustomBorderColorCreateInfoEXT structure in the VkSamplerCreateInfo::pNext chain.

The VkSamplerCustomBorderColorCreateInfoEXT structure is defined as:

// Provided by VK_EXT_custom_border_color
typedef struct VkSamplerCustomBorderColorCreateInfoEXT {
    VkStructureType      sType;
    const void*          pNext;
    VkClearColorValue    customBorderColor;
    VkFormat             format;
} VkSamplerCustomBorderColorCreateInfoEXT;

Description

Note

If format is a depth/stencil format, the aspect is determined by the value of VkSamplerCreateInfo::borderColor. If VkSamplerCreateInfo::borderColor is VK_BORDER_COLOR_FLOAT_CUSTOM_EXT, the depth aspect is considered. If VkSamplerCreateInfo::borderColor is VK_BORDER_COLOR_INT_CUSTOM_EXT, the stencil aspect is considered.

If format is VK_FORMAT_UNDEFINED, the VkSamplerCreateInfo::borderColor is VK_BORDER_COLOR_INT_CUSTOM_EXT, and the sampler is used with an image with a stencil format, then the implementation must source the custom border color from either the first or second components of VkSamplerCreateInfo::borderColor and should source it from the first component.
