Regarding the serialization of Spiro control points
by Fred Brennan
Greetings,
I write from the FontForge project. Of particular interest to me is the Spiro
spline feature, which was originated around ten years ago by Raph Levien.
One thing I'd like to add, (which would benefit both our projects,) is the
ability of FontForge to understand the Inkscape Spiro serialization format.
However, there are several things about the format which to me as an outsider
appear to be defects serious enough that I have no idea how to even *import*
these splines correctly, much less export our Spiro splines to this format. I
would very much like to support the _de facto_ standard Inkscape has
originated of supporting Spiro in SVG, but I am lost.
George Williams, FontForge's original author, noticed this defect over eleven
years ago.[1] Things are virtually unchanged since then, I checked `git
blame`.
Spiro has five point types, not including beginning and ending points. They
are:
* G4 curve (o)
* G2 curve (c)
* Corner (v)
* Left Constraint ([)
* Right Constraint (])
The ASCII single letters are the normal method of Spiro serialization, as
championed by Raph Levien and by us in FontForge.
Inkscape seems to create what I will call a "pseudo-SVG path". So, it is not
really an SVG path, but rather is an SVG path which undergoes transformation
into the typical Spiro format. Inkscape stores this in the "original-d"
attribute.
So, given a Bezier spline with control points defined as (x, y, c1, c2),
Inkscape interprets a control point with only (x, y) to be a corner, meanwhile
a control point with all four is a G4 curve, and (x, y, c1, NULL) is a left
constraint while (x, y, NULL, c2) is a right constraint.
I can probably overcome this, although George Williams was right to be
skeptical of this format. There is no way I can see to define a G2 curve in
this strange "original-d" format.
Thus, this email. I write to ask a few things. I suppose first of all, what
are the chances that we can convince you guys to store Spiro splines in
plate[2] format, or another widely accepted Spiro serialization format?
Second, if we cannot convince you to do that, how do I export FontForge spiros
which contain G2 control points to Inkscape's original-d format? It's not
possible, yes? So should I just silently fail and save them as G4? The curves
will not be the same if I do that. Should I disallow export to SVG w/Spiro if
glyph contains G2 control point? That seems a steep cost that will just
confuse my users, so perhaps I should abandon the whole thing if it comes to
that.
Cordial regards,
Fredrick Brennan (@ctrlcctrlv)

Need help with random transform in cache
by Jabier Arraiza Cenoz
Hi all.
I need help with this about random scaling of cached elements to
document units.
In the function "scheduleTransform" in "src/display/drawing-
item.cpp:603" I recive randomly not scale/document scale affine in
"ctm_change" var.
Can anyone give a look I spend 2 days on it without result... to me is
a 1.0 blocker.
Asume you have this conditions to test:
* Inkscape with cache enabled (size>0)
* Document units diferent than pixels
Testing:
* Output the affine "ctm_change" prefiously mentioned.
* Open inkscape.
* Draw a bigest circle that cover your screen.
* Create multiple text with click + type some leters as fast you can
over the circle.
When the circle become a box, see the output and you discober there is
a diferent scaling with the doc scale, normaly is 0 scale.
Thanks so much for get into, Jabier.

One small bug. When starting Inks, it doesn't become the top

Hi, is there any ongoing projects with goal of making inkscape also as modular UX/UI design tool ?
by cosmobird
in my search for foss design tool for UX/UI, Flow design and
organization, so far only very few are available, out of that only few
seems to be working (with some hardwork). but most of them are
proprietary solutions or else oriented towards it.
afaik, inkscape has better design features than any other design tool
out there ... however it lacks a few features to make it as a design
tool for any front end designer.
those are :
1. svg to code conversion
2. library management for projects
3. parametric design convention
4. standard templates
5. animation
if those are made available through python, then it will become
invincible, and i dont know about akira so far, tried but failed to
build several times in this year.
like this :
1. select a target device, 2. choose a template dimension, 3. make flow
for ux (from synthesized user flow in ux design with api), 4.
collect/make icons, fonts, color palettes, 5. get standard components
for the chosen device, 6. integrate together activity by activity in
each discrete flow part of the 3 step. 7. convert every single ui from
step 6 to css or android xml so that the layers, objects can be reused
in Qt, Android, React.
This would definitely give free software projects an upper hand among
the developer community like Fdroid, and other web based projects.
However some very few projects are avaible in FOSS with such ideas, are
no where near to inkscapes design versality.
regards
cosmobird.
