Specify DPI of input image on tesseract command line?

[CaptnClumsy]

Hi,

I have an image which I know is 300 DPI but when I run tesseract (version 3.05.01) on it I get a warning:

   "Warning. Invalid resolution 0 dpi.  Using 70 instead."

How can I tell command line to use 300 DPI resolution?
I tried looking at all the possible parameters using:

    tesseract --print-parameters

But I cannot see a suitable parameter to pass DPI.

Any help much appreciated.

It looks like something is wrong with your input image. Which format does it have?

use the -- dpi option.

Eg: tesseract --dpi 300 inputfile outputfile
