How to convert dicom images with differnt samples per pixel

[George]

Hello,

It would be nice to point to function that can convert a dicom that has a different samples per pixel given a static photometric value.
for example I wish to know how to convert my dicom which is PALATE COLOR from 3 samples per picture to one

Best Regards

A PALETTE COLOR image only has one sample per pixel. That value points to an index table with R, G, and B values.
Effectively this is a space-efficient way to store color images that only use a small number of colors.
If you want to convert an existing RGB image to PALETTE COLOR, you have to reduce the number of colors used by using a dithering algorithm, and then you can compute a color palette. See the dcmquant tool.
