Re: gEDA-user: gschem: low-quality PNG file

["Hiroshi T." <mlht@xxxxxxxxxxxxxxxxxx>]

Thank you for your reply, John Luciani, Charles Lepple and  John  
Coppens.

This is the result:
http://www.tg.rim.or.jp/~hrst/Electronics/Watering_Device/ 
Watering_Device.html

It is written in Japanese (UTF-8) but you can at least see photos and  
schematics :)

I produced the images of these schematics by:
(1) Type 've' in gschem
(2) Resize gschem window to minimize white space outside the titleblock
(3) In print panel, choose 'A4 size' and 'current window'
(4) convert -rotate 90 output.ps output.png

There is unnecessary space over each schematic, which, I suppose, will  
be eliminated by
writing appropriate printing script like your 'gschem-print.scm'.
