VROverlayError GetOverlayImageData( VROverlayHandle_t ulOverlayHandle, void *pvBuffer, uint32_t unBufferSize, uint32_t *punWidth, uint32_t *punHeight )
Gets the raw image data from an overlay.
-
VROverlayHandle_t ulOverlayHandle- Overlay to get image data for -
void *pvBuffer- Application provided buffer to put image data in -
uint32_t unBufferSize- Size of the provided buffer in bytes -
uint32_t *punWidth- Width of the overlay image in pixels -
uint32_t *punHeight- Height of the overlay image in pixels
Description
Gets the raw image data from an overlay. Overlay image data is always returned as RGBA data, 4 bytes per pixel. If the buffer is not large enough, width and height will be set and VROverlayError_ArrayTooSmall is returned.
