Data Structures

struct  VPIPyramidData
 Stores the pyramid contents. More...


 Maximum number of pyramid levels.


VPIStatus vpiPyramidCreate (uint32_t width, uint32_t height, VPIImageFormat fmt, uint32_t numLevels, float scale, uint32_t flags, VPIPyramid *pyr)
 Create an empty image pyramid instance with the specified flags. More...
void vpiPyramidDestroy (VPIPyramid pyr)
 Destroy an image pyramid instance as well as all resources it owns. More...
VPIStatus vpiPyramidGetFlags (VPIPyramid pyr, uint32_t *flags)
 Returns the flags associated with the pyramid. More...
VPIStatus vpiPyramidGetType (VPIPyramid pyr, VPIImageFormat *type)
 Returns the image type of the pyramid levels. More...
VPIStatus vpiPyramidGetNumLevels (VPIPyramid pyr, uint32_t *numLevels)
 Get the image pyramid level count. More...
VPIStatus vpiPyramidGetSize (VPIPyramid pyr, uint32_t outSize, uint32_t *outWidth, uint32_t *outHeight)
 Get the image width and height in pixels (for all levels at once). More...
VPIStatus vpiPyramidLock (VPIPyramid pyr, VPILockMode lock, VPIPyramidData *out)
 Acquires the lock on a pyramid object and returns pointers to each level of the pyramid. More...
VPIStatus vpiPyramidUnlock (VPIPyramid pyr)
 Releases the lock on a image pyramid object. More...
VPIStatus vpiImageCreatePyramidLevelWrapper (VPIPyramid pyr, uint32_t level, VPIImage *img)
 Creates an image that wraps one pyramid level. More...
