## SIMPLE USAGE

**gdcm2pnm** will take as input DICOM and render it into a bitmap file using the window/level attributes value.

```
$ gdcm2pnm input.dcm output.png
```

It is much different from the gdcmraw or gdcmimg command line tool as it will render a DICOM image. This means that the output will be rendered in 8bits ready for display.
