A Setting for the Overlap Factor in Hairpins

IWBNI there were a setting that could be used to control the degree to which adjacent horizontal line segments that form the branches of a hairpin are to overlap. As it is now, there is no way to control the degree of overlap.

When digitized, each of the two branches or line segments of a hairpin are represented by a sequence of short adjacent horizontal line segments. The degree to which these adjacent horizontal segments overlap affects the appearance of a hairpin.

For example, consider the following three portions of a hairpin. Each of these 3 images is a section of the top line of a long decrescendo hairpin, for 3 different hairpins. Note: To see the full width of these images, adjust the screen resolution to be at least 968 pixels wide (e.g. 1024x768).
 
 
 


 
 
 


 
 
 


 
 

These examples have the following characteristics:


This could be implemented by adding the following controls to the Crescendo/Decrescendo section of the Smart Shape Options dialog box:

Smart Shape Options Dialog Box

Crescendo/Decrescendo:

Overlap Factor:
    ( ) Optimize for Space
    ( ) Optimize for Appearance
    ( ) Overlap: _____ %
------------------------------------------

If the radio button Optimize for Space is selected, hairpins would be represented in postscript as two line segments of a specified width that pass through three given points by using a single moveto command followed by two lineto commands, or in the worst case, as four commands: moveto, lineto, moveto and lineto. In this case, the length and overlap of the horizontal line segments of the hairpin branches would be controlled by the display device or printing device that renders the postscript file created by Finale.

If the radio button Optimize for Appearance is selected, the horizontal line segments of hairpin branches would overlap by some predefined value that has been judged to yield an optimal appearance. The percentage 44.44% might be used for this purpose.

If the radio button Overlap is selected, one could specify the degree to which the horizontal line segments of hairpin branches would overlap.
