Re: [disklavier] Re: using a scanner

2003-05-01 by Robert Welcyng

I second everything Tom has said.  Buffy, in using PhotoScore 2, here 
are a couple of critical points you might wish to check:

*  Be sure to use a recent version of PhotoScore.

*  As Tom has advised, start with very crisply printed notation.

*  If you are scanning with your HP software to produce the BMP files, 
make sure you are scanning to 100% size and are set up for 400 X 400 dpi 
resolution (no more, no less).  I also use an HP scanner, a ScanJet 4C; 
its software user interface is absolutely underwater.  Once I got the 
settings figured out, PhotoScore immediately purred.  A scanned 8.5 x 11 
page will be about 11 to 15 MB.  If your scanned BMP files are not in 
that ballpark, that's likely your problem.
