UI issues with pre0
by Arpad Biro
Hi,
In src/ui/widget/style-swatch.cpp we have this code:
if (op == 0)
str = g_strdup_printf(_("0:%.3g"), op);
else
str = g_strdup_printf(_("0:.%d"), (int) (op*10));
The characters before the colons are zeroes. Is this intentional?
Also, there are conflicting mnemonics:
File menu:
_Document Properties
_Document Metadata
Layer menu:
_Layers
_Lower Layer

Inkscape 0.44 String Freeze
by Bryce Harrington
Hi all,
We've hit the point in the release process where no further string
changes should be made (except in very exceptional circumstances). This
enables translators to reach 100% translation rates.
This is also the point where translators should really ramp up
translation activity. We currently have 9 languages rated at
'significantly translated', with another half dozen that are nearly to
that level. We've posted a news item with the current statuses to
http://www.inkscape.org today. Please, if you know someone that knows
english and one of the less well translated languages, consider helping
them in creating an Inkscape translation for their language!

Hi!
Couldn' t find ishmal on #inkscape on irc.freenode.org - Can you send
him my email?
Is there a way to configure Inkscape to save paths as quadratic bezier
curves (Q tag)?
Cordially,
Axel

I think too the extensions should be documented somehere inside inkscape
itself; perhaps adding a good-old help browser to the program. A way of
adding documents to the help as easy as dropping extensions in a directory
would be great.

I've been thinking about ways to improve accuracy since yesterday, and
I have some better math for you. :)
Dividing the curve into line segments and finding their lengths will
always give you an answer that is too low, since line segments will
always take a short-cut around any curved portions. It would be more
efficient to use the Calculus definition, since it takes curvature
into account:
Integral( sqrt( dx/dt ^ 2 + dy/dt ^ 2 ), t )
If you have a point traveling along your spline, the dx/dt and dy/dt
functions tell you the point's x and y velocity with respect to t. The
formula for dx/dt is:
dx/dt =
x0 * (-3*(1-t)^2) +
x1 * (+3*(1-t)^2 - 6*(1-t)*t) +
x2 * (-3*t^2 + 6*(1-t)*t)
x3 * (+3*t^2)
Here, x0 and x3 are the endpoints, and x1 and x2 are the control
points. The formula for dy/dt is the same. Combining these two
functions using the Pythagorean theorem gives the absolute speed of a
point traveling along the spline:
s(t) = sqrt( dx/dt ^ 2 + dy/dt ^ 2 )
In other words, the definition of arc length is just speed integrated
by time, giving distance traveled. Since an integration just divides a
function into infinitely small chunks and adds them up, it can be
approximated with a sum:
double s = 0; //Result
double dt = 0.01; //Step size
for (double t = 0; t < 1; t += dt) {
s += s(t) * dt;
}
Using an infinitely small dt would give you exact integration, but
computers can't do that. :) Using something called Simpson's rule,
however, can improve the results dramatically with almost no extra
work:
int n = 100; //Steps; must be even
double t0 = 0; //Start value for t
double t1 = 1; //End value for t
double dt = (t1 - t0) / n; //Step size
double s = s(t0) + s(t1); //Result
for (int i = 1; i < n; i += 2) {
s += 4*s(t0 + i*dt) + 2*s(t0 + i*dt + dt);
}
s *= dt/3;
You can Google Simpson's rule for more info on the algorithm, but the
accuracy improvements are substantial. Plus, this algorithm is
actually faster than summing lengths of line segments.

No SoC support? Then get down to business !?
by Justin Wikinator
So, I'd like to thank you all for your feedback on my griping about the
SoC. It was comforting and encouraging. As I've explained, I would
still love to be able to commit a lot of time to this project, but my
economic constraints are the only thing holding me back from doing so.
I was speaking with some open source activists from the GOSLING group
here in Ottawa (http://www.goslingcommunity.org) about the SoC
fall-through, and they encouraged me to seek funding for my project
elsewhere. They made it seem very fesable, and they are very
experienced in the world of FLOSS, so I am considering their
suggestion. It occured to me I could get funding for this project in
two ways (1) provide graphics services, where the deliverables would be
images OR (2) provide "value added" to Inkscape, where the deliverables
would be code. It seems these two might feed each other. Do any of you
have suggestions about to get funding for my project ? I've thought to
myself sometimes, "why should I get paid to do this when everyone else
is doing it for free ?" I think the answer to that questions is
"because I (and others) deserve to earn a living doing something
enjoyable and that benefits the public". It occured to me that maybe
some of you ARE getting paid to develop Inkscape. Is this the case ?
How does that work ?
So, in pursuing this goal, I've jotted some courses of action:
- rewrite the proposal to frame it more towards end users like graphic
design companies and give the reasons why this project should be funded
(technical/business/ethical)
- search for other official grants
- get businesses and individuals to start using Inkscape if they don't
already
- promote an official "Inkscape endorsers list" (businesses and
individuals) on the wiki (and have a web button to acompany it) to
develop contacts of those who do use Inkscape
- put up my existing stand-alone scripts on sourceforge
- expand my demo image portfolio on flickr
(http://www.flickr.com/photos/wikinator/sets/72057594111379807/)
- convince individuals and/or businesses who could benefit from my
improvements to Inkscape to invest in my project (one or many ?)
Your continued feedback would be greatly appreciated,
--Justin

effects and impending string freeze
by Aaron Spike
I'm not going to be able to get to work on adding tooltips and
descriptions to the effects until much later this evening. If someone
else has time to look at it great. Otherwise it would be a real jump
start just to get people to list the effects that they think require
more explaination. Unfortunately some of the effects that might require
the most explaination don't pop up an autogui to display it (eg
envelope), this just occured to me.
-Function Plotter needs to say that it requires a selected <rect/>
-Random Tree needs to say that the result will be off canvas
-Fractal (L-System) needs to say that the result will be off canvas
-?

lindenmayer.py
by dsign
I did a few fixups to lindenmayer.py. The original script is already great,
but needed to remove something that seems to me a bug (the extra-segment
stuff). Also expanded a litle the syntax for the rules, so you now can use
A, B, C, D and F for making the job of F, and G,H,I,J,K,L for making the job
of G. As in the original script, you can use other letters to produce only
gramatical expansions and no graphical effects. Now it's posible to render
Sierpinski triangles.
See the attached file to see the problems and the extra stuff.
