Bug Description

The current Inset/outset tools generate a rounded corner when dealing with sharp angled cusp nodes.- This is noticable when dealing with text glyphs for example.

I'd like a set of ennchanced Inset/Outset (termed Geometeric Outset/inset) that does Inset/Outset but does so with the following enhancements.

* Cusp nodes outset/Inset, remain as cusp nodes, So that corners between straight lines remain the same (albiet scaled).

* Differental inset/outset parralllel to X, Y or to a defined axes. (In an laternate tool this proved rather useufl for generating different text weights for a poster, based on a single glyph from a regular font.

JFTR: current and past stable Inkscape versions already offer different inset/outset types based on the object's stroke join type (miter join -> inset/outset with cusp corners; round join -> inset/outset with rounded corners). Path offsets (dynamic or linked) on the other hand currently are always rounded.

The new offset branch retains cusp nodes on outset.

su_v: Can you point me at the relevant manual pages? I need to look into this in more detail?

The attached file is what I got using the "standard Inset/Outset" menu options.

Updated, The orange path is a Dynamic offset with a Miter join set on the original path.... I get a rounded outline, whereas what I was hoping to get was a translated/scaled corner....

The path in red in the attached is what I meant by a geometric Outset ( and this by no means a perfect one, as it was done manually.)

ah... Seeing something. The behaviour I'm seeing isn't do to "big angles" confusing the algorithm used?
