a description of complementary tools

Version:           svn trunk (using KDE 4.5.1) 
OS:                Linux

This one is a very huge feature request!
A feature that is in some famous/standard proprietary software for comic book artists (may be useful for illustrators generally too).

That is to have a special vector system only for line-art (meaning not SVG compliant as it cares only about lines with variable width, not much more)

Working with such vector outlines has 2 main benefit:
-Workflow much improved for drawing clean outlines (as long as we have some adequate tools) due to flexibility of vectors.
-Resolution-independant, meaning you can work on a not too high res. and export to a much higher res with no outline degradation

The thing is now in Krita we ALREADY HAVE a beginning of tool for this: the calligraphy tool !!!

But
 
01 - it needs to be refined:

-very buggy to use for now (I've used it to do the demo file attached, and had to save every few strokes to get something, I had software/system complete freeze VERY OFTEN :/ )
-a curve for the presscurve
-Beginning of strokes sometimes have a little white part (mostly on very wide line strokes)
-End of stroke almost always is minimum width, resulting a peaked end of stroke (same mostly noticeable on wide strokes)
-It has the same bug as the one on "select by brush" tool, becomes crazy when rotated and zoom in a lot.

02 - it needs to get some complementary tools to edit strokes by "painting" areas (as with the select by brush tool for instance) on it:
-One to connect lines
-One to erase some line parts
-One to bend lines
-One to edit line width

For all of these look at the attached demo file.

I hope this is not too much for you ;)

Reproducible: Always

Other things I forgot about this:

-Some complementary simple tools like 3-point spline or classical bezier curve with a "calligraphy" mode (creating some width-editable curves of the same type than the calligraphy curves)

-Calligraphy tool(s) should have some features of the "paint with brush" tool, like assistants or mirror modes.


Also maybe then create a special "Inking layer" type for all this, to separate from standard/svg compliant/karbon shapes (I guess the calligraphy tool is born from Karbon too, but it deserves to grow in Krita in my opinion)

Not sure about the rest of it, but this part of your request:
"-Some complementary simple tools like 3-point spline or classical bezier curve
with a "calligraphy" mode (creating some width-editable curves of the same type
than the calligraphy curves)"


Sounds like my longstanding request:
"Ability to draw and edit curves with variable width" at

Nice to see I'm not the only one who want this feature.

I must say I've updated from master soon after posting this and now I don't have anymore crash when drawing with calligraphy tool (while when when I've drawn the demo file this afternoon I really always had software freeze every less than 10 strokes.. ). That's already a good point.

So is it a duplicate of 201069 or not ?
Comment 6 animtim 2011-02-10 14:36:37 UTC
I wouldn't say this is exactly a duplicate of 201069, but that 201069 can be a part of this one. Except that here I ask for a different tool workflow for tweaking line width.. the description in 201069 is more like Synfig-Studio ink tool system, while I ask something more like what's in the proprietary professional comics software I won't name here ;) .

Confirm.
