97th day of 2016.
Talking about line inking in digital media, the best one I had tried was Paint Tool SAI. Krita does have the same tool albeit in another 'package' since Krita is a Paint programme compare to Image Editing programme.
The tools' name for lining/inking in Krita is called Calligraphy, which used a Vector Layer. There are 2 different layer types in Krita, Paint layer which is Raster and Vector layer which reads Paths.
PRO
+ Each stroke is a separate selection.
+ However, you can have multiple strokes in one Vector layer.
+ Adjustable width, rounding.
+ Easier to apply gradient and pattern effect.
+ Editable path points.
CON
- Have to delete the stroke one by one or select one by one. Though you can select multiple by click and drag the area.
- Unable to micromanage each pressure of path points. (Like in SAI, for the OCD person like me.)
- Seems to have just one nib type.
It bugs me that being able to present with so MANY Brush engines, yet the Calligraphy only has one nib type. I am very likely missing out something there, will have to read the Krita manual.
