Image Arithmetic And Logical Operations Functions

These functions can be found in the nppial library.

Linking to only the sub-libraries that you use can significantly save link time, application load time, and CUDA runtime startup time when using dynamic libraries.

Image Arithmetic Operations

AddC

Adds a constant value to each pixel of an image.

Note: If you use one of the device constant versions of these functions and the function called immediately preceeding that function generates that device constant you MUST either call cudaStreamSynchronize() or cudaDeviceSynchronize() before calling the device constant function.
