aah. That's a pity. >> In more detail: >> - user enters slur editing mode, control points appear. >> - user clicks near first control point >> - holding the mouse button down, he moves the cursor 2 units >> horizontally and 1 unit vertically, then he releases the button. > this is the point where no newly drawn curve can be shown by Denemo > because it does not know where the other control points are. Could you please insert blank lines between quoted message and your reply? I've almost overlooked it. Anyway, to me this feature would be helpful even without new curve preview - i've shaped so many slurs that my brain learned how to calculate bezier curves with quite good precision :) But a preview would obviously be very helpful. Hey, i have an idea: what about conbining both approaches? - user enters slur editing mode, control points appear. - user clicks on first control point - holding the mouse button down, he moves the cursor 2 units horizontally and 1 unit vertically, then he releases the button - Denemo uses this release position as an approximation of resulting control point position (i.e. where the control point will be after \shape moves it) - this becomes \shape #'((2 . 1) ... ) - similarly for other control points. - with all control points done, "new shape preview" would be displayed using information from all "release points". - user can further tweak the curve by dragging points around. looks brilliant! ;) Janek _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
