static Processor* EMAN::TestImageGradient::NEW | ( | ) | [inline, static] |
void TestImageGradient::process_inplace | ( | EMData * | image | ) | [virtual] |
To process an image in-place.
For those processors which can only be processed out-of-place, override this function to just print out some error message to remind user call the out-of-place version.
image | The image to be processed. |
