Hi, I have the issue, that I can use the "nppiRGBToHLS_8u_AC4R" funtion with the CallLibFunction, but always get the function return -6. It seems that the corresponding function "nppiRGBToHLS_8u_AC4R_Ctx" is needed - but I don´t know this for sure and this function cannot be imported with the LabVIEW tool "Import Shared Lib ..." without additional things to be done, that are all not documented. In addition it is not clear to me how to use at least the "nppiRGBToHLS_8u_AC4R" function, that I can import with the LabVIEW tool, properly in LabVIEW: The function outputs "-6" as the function return value - but there is no documentation about that error with exception of this information: "NPP_SIZE_ERROR". Is there a LabVIEW example available that demonstates and documents more exactly, how to e.g. use the functions for allocating memo, up and download img data and how to apply this data to the function mentioned above ... what e.g. about the "Set Current Context.vi" in this context?
With best regards Andreas
