vkCmdCopyImageToBuffer2(3)

C Specification

To copy data from an image object to a buffer object, call:

// Provided by VK_VERSION_1_3
void vkCmdCopyImageToBuffer2(
    VkCommandBuffer                             commandBuffer,
    const VkCopyImageToBufferInfo2*             pCopyImageToBufferInfo);

// Provided by VK_KHR_copy_commands2
// Equivalent to vkCmdCopyImageToBuffer2
void vkCmdCopyImageToBuffer2KHR(
    VkCommandBuffer                             commandBuffer,
    const VkCopyImageToBufferInfo2*             pCopyImageToBufferInfo);

Parameters

commandBuffer is the command buffer into which the command will be recorded.
pCopyImageToBufferInfo is a pointer to a VkCopyImageToBufferInfo2 structure describing the copy parameters.

Description

This command is functionally identical to vkCmdCopyImageToBuffer, but includes extensible sub-structures that include sType and pNext parameters, allowing them to be more easily extended.
