[magick-users] define key= and png formats

[RA A. Winzer (Koenig & Dey)]

Hello,

I could not find a satisfying result for an black and white 1 bit png 
convert. I'm using an openSUSE (10.3 64bit) Linux with the out of the box 
installed convert only. I'm using convert for a png-printer over Samba. I 
can print everything via a script into a png-file. The source is a 
postscript-file.

That's why I tried at least to save the amount of space by reducing the bit 
depth from 32 to 24 (just without alpha-channel). I tried something like

   -define png:bit-depth=24

but without success.

If someone could give me a really good hint for converting to black and 
white I would appreciate as well.

Thanks

Alex

P.S. Sorry for my poor English. I hope you understand at least what my 
problems are...
