LazPaint is great but I can't figure out how to add a new node to a
shape though I've looked at all the
documentation. In other words, is it possible to add another side to
an existing shape without needing to
draw another shape?

I noticed that LazPaint draws antialiased shapes but for my purposes I
do not want antialiasing.
    Can anyone tell me if I can turn antialiasing off in LazPaint? I'd
rather use LazPaint. If that can't
be done then I'll have to use Paint instead and I don't want to do
that. Can ANYONE help?

Well, without a definite resolution then I will have to assume that
LazPaint makes only antialiased lines
and shapes instead of solid color lines and that new nodes/handles
can't be added to existing lines but at
least for my purposes I have MS Paint to fall back on.
    LazPaint is in all other respects a very nice and useful program.
When I think of all the work that must have
gone into it then I'm amazed. Jesus. Circular is a brilliant coder in
company with other such folks in this Forum.
    In the recent and distant past I have received crucial help here.
All kudos to Lazarus.

Hello user5,

To add a node to a shape, you can use the Insert or the I key. It will
insert a new point where the mouse is located. Conversely, you can
delete a point with the Delete key.

Note that if the shape is a rectangle, this won't work directly. You
need first to convert it to a curve (item in Edit menu).

Aliased shapes are not yet available in LazPaint, that's something
that is somewhere on the roadmap.

What you can do to emulate aliasing is to create a palette with list
of colors used and posterize using this palette. Here is how to do it
step by step:
Make sure the palette is visible on the rightmost part of the window
(View menu)Click on its menu (button at the top) and choose Clear
paletteMake sure the color chooser is visible. It will contain the
current colorA. Use the color picker to retrieve one of the colorB.
Click on the button of the color chooser to add the color to the
palette (top-left button in the color chooser)Repeat step A and B for
each of the colorIn the palette menu, click on Posterize layer using
palette
Note that in the current version, this will rasterize the layer,
shapes won't be editable anymore. If you want to keep an editable
version, you can duplicate the layer, hide one of the copy, and
posterize the other. So that if you want to change things, you can
still retrieve the vectorial version of the layer.

That's for the kudos   It has been indeed a lot of effort to make the
software.
