[l2h] changing to 24 bit color depth of images/ keeping existing jpg images?

[Jorgen Johansson]

Hello,

Thank you for the quick response,

to add to this topic I want to ask:

How to make use of the options 'color' 'depth'?
They are on line 373 of the "pstoimg.bat" in my setup.
... -depth=i -color=i ...

I tried to specify them at the command line but L2H
just complains about unknown option. I have not been
able to find some info on how to set this options.

Thanks

jorgen
