Red Spiral Challenge
by Aaron Elmquist
Does anyone know how to creat the red spiral with the continuous gradient in
Tavmjong Bah's "A Guide to Inkscape" I took a couple cracks at it last
night without much sucess.

Type1 Fonts on Windows XP
by Norvell Spearman
How do I configure Inkscape for Windows to see the Type1 fonts I have
installed? The GIMP sees them fine (which also uses freetype), as
does OpenOffice.org. The font names and corresponding pfb file names
even show up in my .fonts.cache-1 file but I still can't see them in
Inkscape. Thanks for any answers.

Inkscape SVG extension / CMYK support
by Cedric Sagne
Hi.
I was wondering there is any place where I could have more information about
feature support for Inkscape SVG vs plain SVG.
Also, I believe SVG does not support CMYK colour space colours (as per
Tavmjong Bah's brilliant userguide), and this is important for logos and
even EPS export gets imported in Scribus with RGB colours....
Any news on the planned CMYK support?

Compiling on Win32
by Docsonic
I followed the directions from JonY to compile the SVN on Win32 (I know
I don't really need to as the new win builds are perfect but I enjoy the
challenge) and I keep hitting the same problem. When I run 'g++
buildtool.cpp -o btool' I get a string of errors starting with -
buildtool.cpp:53:18: error: string: No such file or directory
buildtool.cpp:53:18: error: string: No such file or directory
buildtool.cpp:53:18: error: string: No such file or directory

Tweak tool: soften mode
by Facundo Casco
Hi, I've just downloaded the 20070830 windows build of Inkscape and
while playing with the tweak tool the first thing I wanted after using
the roughen mode was a soften mode, something like a localized
simplify path. The only problem I see with simplify path is that used
after roughen leaves some disconnected nodes, like speckels.
Anyway, great tool and excellent work yo're doing with Inkscape.
Thanks for a great software.

NEW: four more modes in Tweak tool
by bulia byak
Of the four new modes, two are for editing path shapes (Attract and
Repel) and two are for coloring objects (Color Paint and Color Jitter)
. I also renamed Melt to Shrink and Inflate to Grow as discussed
before.
* The Attract and Repel modes work by moving each affected point on a
path towards (Attract) or from (Repel) the cursor point. In some cases
this may look similar to Shrink and Grow, but the difference is that
shrinking/growing moves paths perpendicularly to the path in each
point, whereas attracting/repelling moves them to or from the cursor
regardless of the path shape. These modes are similar to the Pinch
effect in ; you can use them for various central-symmetric distortions
in parts of your paths.
Color-changing modes
The Color Paint and Color Jitter modes, unlike the path editing modes,
change the colors of objects instead of their shapes. Yet they share
enough common features with the path-changing modes to be part of the
same tool: These modes also use a circular soft-edged brush controlled
by the Width and Force parameters on the Controls bar and affected by
the pen pressure (if you have a pressure-sensitive tablet).
* Color Paint applies the style of the tool to the selected
objects under the brush. The style of the tool is visible in the style
swatch at the rightmost end of the tool's control bar; it can be
changed by clicking on the color palette or by any other style
assignment command, such as Fill and Stroke dialog. (Note: unlike all
other tools, in Tweak tool in Color Paint mode you cannot assign style
directly to selected objects; any style-setting command changes the
tool's style instead.)
The fill from the tool's style applies to the fills of the painted
objects, and the stroke applies to the strokes. If the tool's style
has no fill or no stroke, it won't affect fills or strokes,
correspondingly. For example, if you want to color the fills of
objects blue but leave their strokes untouched, assign blue fill to
the tool's style (just click blue on the palette) but set its stroke
to None (middle-click the Stroke swatch in the statusbar). Similarly,
master opacity in the tool's style
This mode allows you to literally paint over objects, shifting
their colors towards the target style of the tool. For example, if you
paint with yellow fill over a blue-filled object, the object will
become greenish blue, then green, then yellowish green, and end up
being exactly the green color you're painting with. This speed of this
gradual transition depends on the Force and pen pressure; also,
objects touched by the periphery of the brush are less affected than
those hit by the brush center. Overall, using this tool is very
similar to a soft brush in a raster editor such as Gimp or Photoshop.
* Color Jitter mode does not apply any color, but instead jitters
(randomizes) the colors of the objects it touches. The force of the
action determines how strong is the randomization, i.e. how far the
colors deviate from the original values. This mode does not use the
tool's style.
Both modes work on flat fills and gradients; for gradients, the tool
takes into account not only the position of the entire object with
gradient, but also the position of each gradient stop relative to the
brush. This means that, for example, you can change the blue color
only in an object filled with blue-red gradient simply by painting
over its blue end with a brush small enough to not touch the red.
Channels
Color Paint and Color Jitter honor the Channels control. This control
comprises the four buttons: H, S, L, and O, which allow you to turn on
and off the tool's action on the object's hue, saturation, lightness,
and opacity, correspondingly. For example, if you want to raise the
saturation of some part of your drawing without changing the hue,
select some maximum-saturation color (e.g. pure red) and turn off all
Channels buttons except S. Similarly, you can replace the hues without
affecting saturation or lightness (only H pressed), or lighten/darken
all colors without changing their hues and saturation (only L
pressed). Pressing O allows you to apply the master opacity from the
tool's style to the master opacity of objects (but not fill or stroke
opacity).
Usage notes
Color painting with Tweak tool is similar, but not exactly analogous
to bitmap painting. Even though the tool itself works as a soft brush,
it still applies its color to vector objects, which behave as vector
objects usually do. For example, if you want to change the tint of the
face in your drawing, and if a hand in the drawing is part of the same
object as the face, that hand will change its tint too even if it's
located far from the point you are painting. (We foresee a "fracture"
command in one of the next versions of Inkscape which will help you
turn a monolithic object into a mosaic of small fragments that will be
then easy to paint with Tweak tool.) Still, even with this limitation,
color painting is a novel way of dealing with vector drawings which
allows you to quickly and intuitively make adjustments which would be
awkward and slow with traditional approach.
Drawings containing patterns or scatterings of small independent
objects are best suited for color painting with Tweak tool. Examples
include:
* freehand drawings with Calligraphy pen, consisting of many
separate strokes;
* gradient meshes imported from Adobe Illustrator files (Inkscape
renders these meshes as lattices of small polygons; while there's no
direct support for gradient meshes in Inkscape yet, color painting on
such lattices is almost as good);
* text converted to paths and with Break Apart command applied so
that each letter is a separate path;
* patterns made with the Tile Clones command; note that you need
to unset the fill and/or stroke on the original object and use the
Color tab to assign some initial color to the clones - this will make
them paintable with the Tweak tool without unlinking.
Moreover, color tweaking can be useful for compositions with a few
objects or even for single objects. Unlike all other color selection
methods, painting with the Tweak tool implements the color mixing
metaphor which is much more familiar to traditional artists than RGB
sliders or even the color wheel. For example, start with a rectagle of
pure blue color; then, pick different colors by Color Paint and apply
light touches with minimum Force and minimum pen pressure: add a
little green, a little brown, a little yellow, etc. until you have the
exact hue you need. Similarly, you can whiten or blacken any hue by
admixing white or black.
You can also use color tweaking to add a tint, darken/lighten,
saturate/desaturate, or color jitter your entire drawing. Just select
all in all layers, zoom out, choose a large brush width so it covers
all of the drawing, and apply a little color tweaking (with minimum
Force) that will therefore affect all visible objects.

Another newbie question
by David Gressett
Situation: I draw a circle, then draw a smaller object superimposed on
the circle. Is there a way to move the center of rotation of the smaller
object so that it will snap to the center of the circle?
