C Specification

The XrVirtualKeyboardTextureDataMETA structure is defined as:

// Provided by XR_META_virtual_keyboard
typedef struct XrVirtualKeyboardTextureDataMETA {
    XrStructureType    type;
    void*              next;
    uint32_t           textureWidth;
    uint32_t           textureHeight;
    uint32_t           bufferCapacityInput;
    uint32_t           bufferCountOutput;
    uint8_t*           buffer;
} XrVirtualKeyboardTextureDataMETA;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.

  • textureWidth is the pixel width of the texture to be updated.

  • textureHeight is the pixel height of the texture to be updated.

  • bufferCapacityInput is the capacity of buffer, or 0 to indicate a request to retrieve the required capacity.

  • bufferCountOutput is filled in by the runtime with the byte count written or the required capacity in the case that bufferCapacityInput is insufficient.

  • buffer is the pixel data in linear color space, RGBA 8-bit unsigned normalized integer format (i.e. GL_RGBA8 in OpenGL, VK_FORMAT_R8G8B8A8_UNORM in Vulkan).
