How to convert a dicom file from RGB format into MONOCHROME2?

Hi ~ I need to convert DICOM files from RGB format into MONOCHROME2, I tried to use "dcmcjpeg + cm + pl sour.dcm dest.dcm", but this will be converted to jpeg file format is there another way? thank you

dcmscale shows how to use the DCMTK to read a DICOM image file, transform the pixel data with the DicomImage Class and write a new DICOM image file. The conversion from color to monochrome can be achieved with DicomImage::createMonochromeImage().

I have a multi-frame image of RGB format.
Does DicomImage::createMonochromeImage() convert all the frames from RGB to MONOCHROME2?

Does DicomImage::createMonochromeImage() convert all the frames from RGB to MONOCHROME2?

Yes, if all frames are actually selected for being loaded/processed (see DicomImage constructor).
