Now that the Eraser tool is in SVN for quite some time, what do people
think of it? Is it useful? In what mode do you use it, if at all?
Disclaimer: as you may remember I was against this tool from the
beginning, considering it redundant. Its Delete mode is equivalent to
Alt+drag followed by Del in Selector, and its Cut mode is now
equivalent to Alt+drag in Calligraphic pen which I just added:
* When drawing with <b>Alt</b>, Inkscape <b>subtracts</b> the path
you
have created from the selected path (with <b>Shift</b>, it adds to the
selected path). This allows you to quickly patch or fix problems in a
stroke you have drawn without leaving the tool.
So, do we really have to spend the prime toolbar space on a tool which
does what other tools already do?

I rarely use the eraser tool but I'd hate for it to go away. I suppose someday it
would be nice to
have the toolbox toolbar customizable so that users could add or remove icons. Perhaps
that doesn't
make sense now but if you ever added more tool options in the future...

What happens when in Calligraphy tool preferences you have it set not to
Select new path?
I think this does make Eraser tool redundant, the only advantage of the
eraser tool is because newbies feel more confident with it being there.

If you had a path selected before you start Alt+drag, this setting
does not affect its operation.

I don't use it too often, but only when it offers something to be done a
little easier. Specifically the cutting through a selection of multiple
objects. If our boolops did that, I would probably just use that
instead. I think as a tool, if it was more robust, I probably would use
it much more often then.

Very cool! The only request that I'd have is as above, if you could make
it operate on multiple objects in the way that the Eraser tool does,
that would rock.
So, do we really have to spend the prime toolbar space on a tool
which

This is a difficult question. I agree with Mihaela about the possible
benefit to making the program feel more approachable to newbies. Also
when I use my tablet, it is handy to flip the pen over as Alexandre
mentioned. I also think that if the tool were fleshed out a bit more it
could be quite useful.
For example, if it had a scalpal/knife/scissors (whatever) mode that
would make 0-loss cuts (only cutting, not removing pieces), that would
be fantastic. Alexandre also mentioned an idea for a non-destructive
mode that used the boolops lpe, which would also be great and different
(and I would exclusively use it over destructive cuts).
Just my .02, in it's current state it doesn't offer much, but it could
have potential.

I haven't been using it, because I only use the packages provided in
Ubuntu, and they don't have it. I'm not sure you can draw any
conclusions with the small amount of people that use SVN compared to
Inkscape userbase.
Lack of Eraser tool has always been the most lacking feature in Inkscape
- but that's because I'm not doing technical diagrams and such all the
time. When using a drawing tablet in calligraphy mode, you're always
looking for an Eraser, because other methods don't feel natural.
Actually, that's one of the missing features where you feel Inkscape
isn't adapted for drawing tablets (note I didn't say "isn't suited"
-
Inkscape in Calligraphy mode is one of - if not the - most natural
feeling drawing programs in Linux).
Alt+anything doesn't work, because the Alt key is the key used to move a
window on my DE. Also, I'm not sure how using a mouse would make it
suddenly more natural, but when using a drawing tablet I'd hardly say
having to press a button (or an ExpressKey©) when drawing with the other
hand is the way to go.
Toolbar space is prime, but having a natural eraser is priceless. Also,
if one day Inkscape support assigning different tools for each input
device, we'll definitely get a use for pencil erasers.
Pen tip = Calligraphic Pen
Eraser = Eraser
Mouse = Paint Bucket
If I was only in technical drawings / drawings with a mouse I'd say an
Eraser is useless. For natural drawing, where you're constantly
drawing/erasing, it's a huge improvement.

Would you like to try it? If you go to
https://launchpad.net/~inkscape-nightly/+archive/ppa it has repository
info for testing inkscape-svn. It can be installed along-side of the
officially supported version too, so there is nothing to lose.

Ouch... you're missing out a lot in Inkscape (alt is incredibly useful).
I switched my "move window" key to the Win key just for that reason...
my commitment to getting the most out of Inkscape. ;)

At least with Pen tip and Eraser, it does remember the assigned tools
for each (not sure about mouse). It would really be great though if you
would be willing to test inkscape-svn via the repo above and give some
feedback based on what you experience.

I actually quite like the concept of having it as a tool (I'm not a
big fan of modifiers when using my tablet), but currently the option
in the callig tool is much more useful to me as it has all the
fixation etc options that I need to actually make it useable. The
eraser is stuck on a slanted fixed angle that makes it a lot less
useful than it could be. would be nice if using the eraser on the
wacom in the callig tool did the alt mode, if that was the case i
think i'd be fine without the seperate tool...

New subject: Extracting formulas from curves?
People,
Is there a way of extracting the formula for the curve from the attached
svg ie in something resembling a conventional y = f(x) format?
Thanks,

New subject: Extracting formulas from curves?
well.. maybe.
it is a bezier curve. It is a parametric curve whose coordinates are
defined by quadractic equations:
x(t) = a*t² + b*t + c
y(t) = d*t² + e*t + f
finding the values of a,b,c,d,e and f involves looking at the
coordinates of the control points of that curve and doing a bit of
math
Not all bezier curves can be described as 1 parameter functions,
though... I think that it is indeed possible to do that with the one
you provided since it appears to have a single y value for each x
coordinate, thus it satisfy the requirements to be called a function.
what are you trying to do with this math stuff?

No, at least not from Inkscape as far as I know. If any, you'd get x(t) and
y(t) with t in the range of [0,1]. If you need more details then lookup
Bezier curves on Wikipedia or leave a message on the 2geom mailing list.

Exactly. To make it truly useful as a subtractor, we would need to
duplicate most of the Calligraphic tool. Which would be bad from both
the UI perspective and the coding perspective.

Absolutely. Would it work for everyone if turning the pen over would
switch you to Calligraphic tool with Alt reversed, i.e. erasing
without Alt and drawing with Alt?

Is it possible for the eraser tool to just link to the calligraphy tool
in Alt reverse mode? I think it makes sense to have an icon (it's more
user friendly, really), but not to duplicate code (or do a less useful
job with different code).
If it is possible, could it then use and store different parameters so,
in essence, it acts like its own tool but operates exactly the same as
the calligraphy tool (with alt reversed)?

I sometimes wish the eraser tool was a round shape (circle) instead of a calligraphy
shape, similar
to Gimp's round brush. That always made sense to me but then again I haven't ever
read why the
eraser tool is the way that it is. Perhaps it's done that way for a reason.

In a post I made to this mailing list recently enough not to have any
reply yet, naive new user (me) asked for precisely a way to erase part of
a path ajd redraw it freehand.
I never dreamed I'd have to look at a calligraphy tool for this. From
this thread, it looks like that may be the right tool. I was on the
verge of going back to paper and pencil and scanner. In any case, I
think I'll have to find some documentation how to use this.
Or am I wrong? Is this not the way?
By the way, I didn't find the eraser tool on the inkscape I'm using (in
Debian lenny, and therefore probably out of date)
