## C Specification

To resolve a multisample color image to a non-multisample color image, call:

    // Provided by VK_VERSION_1_0
    void vkCmdResolveImage(
        VkCommandBuffer                             commandBuffer,
        VkImage                                     srcImage,
        VkImageLayout                               srcImageLayout,
        VkImage                                     dstImage,
        VkImageLayout                               dstImageLayout,
        uint32_t                                    regionCount,
        const VkImageResolve*                       pRegions);

## Parameters

- `commandBuffer` is the command buffer into which the command will be recorded.

- `srcImage` is the source image.

- `srcImageLayout` is the layout of the source image subresources for the resolve.

- `dstImage` is the destination image.

- `dstImageLayout` is the layout of the destination image subresources for the resolve.

- `regionCount` is the number of regions to resolve.

- `pRegions` is a pointer to an array of VkImageResolve structures specifying the regions to resolve.

## Description

During the resolve the samples corresponding to each pixel location in the source are converted to a single sample before being written to the destination. If the source formats are floating-point or normalized types, the sample values for each pixel are resolved in an implementation-dependent manner. If the source formats are integer types, a single sample’s value is selected for each pixel.

`srcOffset` and `dstOffset` select the initial `x`, `y`, and `z` offsets in texels of the sub-regions of the source and destination image data. `extent` is the size in texels of the source image to resolve in `width`, `height` and `depth`. Each element of `pRegions` must be a region that is contained within its corresponding image.

Resolves are done layer by layer starting with `baseArrayLayer` member of `srcSubresource` for the source and `dstSubresource` for the destination. `layerCount` layers are resolved to the destination image.
