RE: FW: Visual Slur Tweaking Tool

[Stewart Holmes]

Hello again. I've recompiled for Java 1.5, and tidied up/fixed some things.
www.stewartholmes.com/LilypondBezierTool.jar. 

Bertalan; regarding your calculation for staff-space to pixels. I tried your
values, but they turned out a touch too short. I then made a Lilypond file
with a slur that I told Lilypond to make a straight line 50 staff-space
long. I measured the number of pixels this took, then simply divided to find
the number of pixels per staff-space. Since I figure that the relationship
between staff-space and staff-size is linear, I multiply this by a factor
dependent on the staff space.

As regards inclusion into LilyPondTool; could it just be added more or less
as is? It uses nothing special other than JPedal, which LilyPondTool already
uses.

Thanks,
Stewart

Hi,

This tool is very nice. It definitely would have its place also in 
LilyPondTool. I think it will be the first thing I put into the next 
version.
There's only some minor things I'd like to suppose:
- compile it for the Java 1.5 target, because 1.6 is so fresh that most 
people has not upgraded yet (and will not for a year I suppose)
- it would be good, if the control points could be aligned with a 
button-click to the blue handle
- there are nullpointerexceptions thrown in the background while there 
is no file loaded, that's a bit disturbing

I saw in your code that at last you didn't use my formula for 
calculating pixels to staff space. Have you come out some more precise 
solution?

Congratulations, again. (If you'd like to include it into LilyPondTool 
yourself, you're welcome ;-) )

Bert
