Auto-Scroll whilst creating paths ...

  • New type of auto scroll useful whilst creating paths/objects.
  • Triggered when the mouse pointer gets with-in a set margin from the edge of the screen. (X pixels).

Parameters ...

  • 1) trigger margin...(ie the width of the virtual boarder (in pixels) around the edge of the screen that triggers the auto-scroll function.)
  • 2) Pan Incrament... how far the screen moves in relation to the position of the mouse pointer...I.E pan to center on pointer, pan half way to pointer, or pan past the pointer etc....
  • 3) weather to reposition the mouse pointer relative to the screen or to so maintain its position relative to the design....

(This option is to accommodate pen tablets that map the screen directly to the tablet itself)...

Anyway the effect of this autoscroll is that when the user gets to the edge of the screen, it is usually set to, automatically re-position the scren to center the area where you were when you hit the edge of the screen so you can continue your path....

It can be a little jarring for some people but you quickly get used to this... I would recommend that an additional option for this function would be a second margin should be able to be defined inside the active area that would be a warning margin..I.E that when you got say between 20-10 pixels from the edge of the screen a warning would happen by way of flashing the cursor once ETC.. and then when you got to with in say 10 pixels (the active area) the autoscroll (re-center) would be executed...

New Inkscape input tool...

  • A new input tool for inkscape, similar to xara,s "shape editor tool", the main input tool for xara extreme.
  • Input is with "curve nodes" and "corner nodes"
 Input with both types of nodes would be exactly the same as if you were to
 laying down a bunch of corner nodes using the pen tool.
 However the "curve nodes" although created like corner nodes would be like
 corner nodes that had been converted to smooth nodes. 
  • This tool would have a 2Button mode where Left mouse would be for "curve points" and "Right mouse" for "corner points"
  • Ideal host tool for Spiro: as it is not a Beizier input method.

  • An alternative input tool more accurate than sketching with the pencil tool and twice as fast as the beizier tool.

  • Very intuitive: Anyone can use it with virtually no learning curve...
  • Excellent tool for tracing accurately if you work off raster art...
 (Allot of artists like to sketch on paper then scan it in and import the art
 and use this as the basis/framework for their vector design....)
 This tool is very good for this type of work....

Tool synthsis

This new input method would allow the user to incorporate sketch, beizier and Curve/corner input modes for different segments of the same path with out changing tools... And the way this would be executed could be tailored in options to suit the user.


  • Totally configurable.

All the input options for this tool would available in options and could be configured individually in its options that it could be taylored to a specific input device of to suit personal taste... For example:

 1) Curve node ------> [left mouse].
 2) corner node -----> [Hold Shift]+[Left Mouse]
 3) Sketch Segment --> [middle Mouse]-(Click & Drag to sketch)
 4) bezier segment --> [alt] - (active whilst held)
 5) finalize --------> [Right mouse] or [Enter]
 6) node reduce -----> [Hold Shift]-[mouse wheel]

OR you could configure any way you wanted I.E another example

 1) Curve node ------> [right mouse]
 2) corner node -----> [Left Mouse]
 3) Sketch Segment --> [Left Mouse]-[Hold shift]-(Click & Drag to sketch)
 4) bezier segment --> [alt] - (active whilst held)
 5) finalize --------> [Middle mouse]
 6) node reduce -----> [Middle mouse and hold down]-(move mouse to control)


This would allow great flexibility to accommodate a wide range of input hardware and also personal preferences.
