Typedefs | |
| typedef struct dwImageTransformationParameters | dwImageTransformationParameters |
| typedef struct dwImageTransformationObject * | dwImageTransformationHandle_t |
| The image transformation handle. More... | |
Functions | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_initialize (dwImageTransformationHandle_t *handle, dwImageTransformationParameters params, dwContextHandle_t context) |
| Initializes an Image Transformation Engine with the given parameters. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_reset (dwImageTransformationHandle_t handle) |
| Resets an Image Transformation Engine. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_release (dwImageTransformationHandle_t handle) |
| Releases the passed Transformation Engine, deallocating all the resources used. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_appendAllocationAttributes (dwImageProperties *const imgProps, dwImageTransformationHandle_t handle) |
| Append the allocation attribute such that the images created of type DW_IMAGE_NVMEDIA can be fed to dwImageTransformation_copy,. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_registerImages (dwImagePool imagePool, dwImageTransformationHandle_t handle) |
| Register all images that the transformation engine has to work with. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_setCUDAStream (cudaStream_t stream, dwImageTransformationHandle_t handle) |
| Sets the cuda stream used by the APIs of Image Transformation. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_getCUDAStream (cudaStream_t *stream, dwImageTransformationHandle_t handle) |
| Gets the cuda stream used by the APIs of Image Transformation. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_copy (dwImageHandle_t outputImage, const dwImageHandle_t inputImage, const dwRect *outputROI, const dwRect *inputROI, dwImageTransformationHandle_t handle) |
| Resizes the input image subregion and copies the result into the previously allocated output image, in a specified subregion, of the same type (CUDA or NvMedia) and format (any) Note that when the images are NvMedia, synchronization with NvMedia2D (VIC unit) will be handled automatically through the cudaStream set (see dwImageTransformation_setCUDAStream) when in non safety environment. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_fillNvSciSyncAttrs (NvSciSyncAttrList syncAttrList, dwSyncType syncType, dwImageTransformationHandle_t handle) |
| Fill the sync attributes for the imagetransformation to signal EOF fences. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_setNvSciSyncObj (NvSciSyncObj syncObj, dwSyncType syncType, dwImageTransformationHandle_t handle) |
| Set the sync obj to which the imagetransformation will signal EOF fences. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_getEOFFence (NvSciSyncFence *syncFence, dwImageTransformationHandle_t handle) |
| Get EOF fence of the current operation. More... | |
| DW_API_PUBLIC dwStatus | dwImageTransformation_addPrefenceWait (const NvSciSyncFence *syncFence, dwImageTransformationHandle_t handle) |
| Add prefence for NvMedia2D to wait. More... | |
