you can restart page with page -p 150 (or some other percentage)
and it will make the ps bigger or smaller using gs
and thus look better. 

i managed to make this work in a running page once
but i have misplaced the code at the moment.

yes i know this option, but my point was to see a zoomed-out document like it was resampled via 
'resample.c'  ... the code is already there, i noticed, but, again: it may be that page requests 
the already scaled document from gs, thus it being a responsibility of gs. 
dunno...

thanks, regards,

The resizer in page(1) is fairly crude - it trades quality for speed.

On windows and the like the resizing is often done in hardware (in the graphics card),
unfortunaletly plan9 makes no use of such features so it has to do a pure
software implementation - hence the tradeoff.

[9fans] page and .ps bitmaps

[cej]

hi all,

when using 'page' to look at postscript files that include bitmaps, they appear rough unless they are
scaled 1:1 with original bitmap included within ps -- it may, however, be a problem of gs not resampling bitmaps properly:
i am ,unfortunately, not skilled enough to find out in sources how page calls gs,
sorry,
would like to know where the problem is,
thanks,

++pac
