NEW: Tweak tool
by bulia byak 23 Aug '07

23 Aug '07

As discussed before, I moved the thinning/thickening functionality into a tool of its own, added two more modes and some controls. For one thing, you don't need Alt anymore :) Attention lib2geom hackers: please consider this a challenge! Can you switch this to using your new lib instead of livarot? Livarot sucks big time with regard to performance and memory leaking (see Known Problems below), and working with it involves way too much black magic which I don't like. What is needed is simple: convert a path to a polygon with a given tolerance, move the points of the polygon according to some simple algorithm, and convert the result back to path with some simplification. If someone switches this to lib2geom and it works good, I will consider adding more modes. Otherwise, I'm afraid I may have to remove the Roughen mode before the release because it's really not working reliably enough (often locks the path with the "directed eulerian" warning, caused by too small subpaths). Now for the official announcement: Tweak tool The Tweak tool is an exciting new way to edit paths. Unlike the Node tool, you don't need to worry about where the nodes of a path are and how to manipulate them to obtain the shape you want. Instead, you just act on any part of a path using the tool's "brush" in order to bend, twist, or stretch that part, and the path will respond smoothly and naturally regardless of where its nodes lie. While not very useful for technical applications such as schemes or diagrams, this tool will be indispensable for artistic uses of Inkscape - cartoons, drawings, sketches, anime, etc. This new functionality is somewhat similar to the "Pucker", "Bloat", and other similar tools in the latest versions of Adobe Illustrator, except that in Inkscape it works softer and is easier to control. The area of the tool's action (its "brush") is visualized as an orange-colored circular outline centered at your mouse pointer. However, that area actually has no sharp boundaries; the power of the tool's action falls off gradually, following a smooth bell-shaped profile. This makes the tool act softly and smoothly, and the paths respond as if they are made of soft jelly. The tool will work on any number of selected objects; for example, you can select all (Ctrl+A) and "smear" your entire drawing by Push. If applied to a shape or text, the tool converts them to paths automatically. You can also apply it to groups of objects. If you're trying to use it without anything selected, it will remind you to select some objects by a statusbar message. Width The width of the tool's brush can be changed by the Width control in the tool's controls bar above the canvas (in the range from 1 to 100). You can also change width by Left and Right arrow keys (same as in the Calligraphy tool) at any time (including during action). Also like in Calligraphy tool, the visible width of the brush is independent of zoom; simply zooming in or out is often easier than adjusting the width if you want to cover a smaller or larger area of the drawing. Force The next control is Force which adjusts the power of the action (in the range from 1 to 100). You can also change width by Up and Down arrow keys at any time (including during action). Think of it as the force of pressure you apply to the paths you tweak. If you have a pressure-sensitive tablet and the "Use pressure" button on the right-hand end of the controls bar is on, then the force will also depend on how hard you actually press your pen into your tablet, varying in the range from zero to whatever you set in the Force control. If all you have is a mouse, then the force will be constant but still settable by the Force control. The force of the effect also depends on zoom (or in other words, it stays the same when measured by screen pixels, same as when you move and object by Alt+arrow keys). Fidelity Any tweaking of a path slightly distorts the entire path, including even those parts that you didn't touch. These distortions are similar to those that a Simplify command produces. The Fidelity value (also in the range from 1 to 100, default is 50) allows you to control the amount of these distortions. With a higher fidelity, the distortions are less noticeable, but the path may end up having a lot of nodes which blows up the SVG size and slows down Inkscape. The best value of Fidelity depends on the nature of your artwork. If you're sculpting an amorphous blob, you can do with low fidelity of about 20. If, however, you are pushing or blowing a text string (as a single path) and want the letters outside the distorted area to remain crisp and clean, you will need to raise fidelity to 80 or more. Modes There are currently four modes in the Tweak tool: Push, Melt, Blow, and Roughen. * This default mode of the tool, Push, simply displaces the part of the path under the cursor in the direction of the drag. The path behaves like soft jelly, bending and bulging smoothly and naturally. It's an easy way to produce various irregular, lifelike, handmade-looking shapes starting from something as simple as an ellipse or a calligraphic stroke. For parallel-stroke hatching (engraving) done in the Calligraphy tool, pushing is an easy way to bend, pinch, or curve the entire hatching uniformly. * The Melt and Blow are two opposite modes that move each point of a path in a direction perpendicular to the path's surface at the point, either inwards (Melt) or outwards (Blow). This is similar to the Inset and Outset commands, except that the Tweak tool can act on a part of a path instead of the whole path. For example, the visible lightness/darkness of an engraving hatching may not exactly correspond to your artistic intention. Also, the ends of strokes are often far from ideal - they may be too blunt or have unsightly bends or blobs. This is where the Tweak tool may help. Select all the strokes in a hatching pattern and apply a light Melt action where you want the lines to become thinner (and the hatching to become lighter), up until total disappearance. If you press hard, melting works as an eraser, so you can easily clean the strokes' ends in a hatching to making them thin, sharp, and uniform. Conversely, applying Blow makes strokes wider (i.e. the hatching becomes darker). Of course, melting and blowing are useful not only for calligraphic strokes. Same as with Push, with Melt and Blow you can sculpt any path, spawning smooth treacle-like appendages with Blowing and carving holes with Melting. Unlike the "node sculpting" mode in the Node tool, however, this does not require adding new nodes, selecting any nodes, or even being aware of nodes at all. * The Roughen mode does exactly this: roughens the edge of the path without changing its overall shape. Slight roughening simply makes the edge crooked and uneven; strong roughening tears and explodes the edge into random blobs and splotches. Note that this operation, especially with high Fidelity, adds a lot of nodes which increases the size of your SVG document and may slow down Inkscape considerably. In particular, pushing/melting/blowing of a roughened path becomes much slower and more difficult, so it's recommended to finalize the overall shape of a path first and roughen it, if necessary, only as the final step. Keyboard shortcuts * W, Alt+F2: switch to the Tweak tool * Shift+P: switch to the Push mode * Shift+M: switch to the Melt mode * Shift+B: switch to the Blow mode * Shift+R: switch to the Roughen mode * Left, Right: change width * Up, Down: change force * mouse drag: act on selected path in the current mode * Ctrl+mouse drag: temporarily switch to Melt (while Ctrl is down) * Shift+Ctrl+mouse drag: temporarily switch to Blow (while Shift+Ctrl is down) Known problems Known problems with the Tweak tool: 1. it is rather slow; 2. it quickly eats memory; and 3. it is sometimes buggy - thin calligraphic strokes may suddenly disappear or change their shape drastically as you're melting or blowing them. For (3), it helps to increase Fidelity. Also, you can undo the bad change and try again with less pressure on the pen - if you do your thinning in several light touches instead of one heavy press, usually you will be able to get the desired result without the buggy behavior. Also, sometimes after roughening, further tweaking of a path becomes impossible with this diagnostic: WARNING **: Shape error in ConvertToShape: directedEulerian(a) == false All these problems stem from the livarot library that we use for geometric manipulation of paths. Fortunately, livarot is scheduled for replacement by lib2geom, a new library now in development, so hopefully these issues will be addressed then. -- bulia byak Inkscape.

Unable to read keys file /usr/local/share/inkscape/keys/default.xml
by Diederik van Lierop 22 Aug '07

22 Aug '07

Hi, When starting the latest and greatest Inkscape (compiled from SVN) I get this: ** (inkscape:6280): CRITICAL **: Inkscape::XML::Document* sp_repr_read_file(const gchar*, const gchar*): assertion `Inkscape::IO::file_test( filename, G_FILE_TEST_EXISTS )' failed ** (inkscape:6280): WARNING **: Unable to read keys file /usr/local/share/inkscape/keys/default.xml My keys are located however in /home/diedenrezi/eclipse_workspace/trunk/share/keys/default.xml What's causing this? I've recently reinstalled Fedora on my pc; did I configure something incorrectly? I've got v0.45.1 from the Red Hat repos installed in parallel, are these conflicting? This used to be working nicely before the reinstall... Thanks, Diederik

Nope. I think I understand what's going on. The culprit is the font you use. See, when a path contains an inner subpath, that subpath makes a hole only when the direction of that subpath is contrary to that of the outer path. Otherwise, if their directions are the same, there's no hole - the path is solid. That's why, if you convert an O to a path and break apart, you get two paths, and when you combine them back, you get the hole back. If you break apart, Path > Reverse the inner path and combine, you won't get a hole. Now, in your font, for some weird reason, the direction of path in "o" is opposite to that of "d" and "g". Therefore when you convert "dog" to path, the places where the letters overlap become holes. And Union of a path with itself only removes the non-hole overlaps as extraneous; it does not touch holes because it assumes they are there for a reason. Therefore, you could not remove those holes in letter overlaps neither by offset nor union. One way to fix this would be, after converting to path, select both inner and outer parts of "o", Path > Reverse them, then combine everything back and Union. Or just use a different font :) It would also help, btw, to not work always in Outline mode - in normal mode it's much easier to see if some overlap is a hole or not (because you have fill). You could also note in regular mode that you have an atrociously huge stroke width (73px!) on your shapes which I assume isn't really necessary for a cutter :) -- bulia byak Inkscape.

Problem with Scim and choice of fonts with non-latin-characters in name
by Gerrit Sangel 22 Aug '07

22 Aug '07

Hello list, I have two problems with Inkscape: 1. Everytime I want to input Chinese, Japanese, Korean or a Raw Unicode Value, I use Scim (more precisely Skim). Usually, the not yet committed string of characters is displayed on the spot, the same way as ordinary (e.g. German) strings are displayed. When I choose another character in Scim, the previously written character in the text is deleted and replaced by another one. (See http://en.wikipedia.org/wiki/Japanese_input_method#Kana_to_kanji_conversion as an explanation of how this works). In Inkscape, by contrast, the precommited string is displayed in a seperate box which is somewhere on the screen. I can do all the actions there, but it is extremely annoying because I always have to search the little box and not before I submit the string it is shown in the destinated area. See http://img444.imageshack.us/img444/1135/scimgm1.jpg I have the same problem with Abiword, so I guess it is somehow a problem of GTK. But I do not have the problem with Firefox, so I think there must be a solution to it. I do not have any other gtk programs (apart from Openoffice, but there, scim does not work in any way) so I cannot test this any further as to where this happens. I can't really stress how annoying this problem is. It makes Inkscape almost unusable for typing a longer text in a CJK language. I have Gentoo and tested it with version 0.45.1 2. Also I wanted to choose the fonts “EPSON 教科書体Ｍ” and “文鼎PL細上海宋Uni” in a text field. Note the Japanese/Chinese characters in the font name. Inkscape did display the fonts correctly during the initial font choice, but after I chose the font, it just displayed “EPSON”. It did not choose the Font, then, but happily continued using the former font. Thanks Gerrit Sangel

Pixelated gradients
by microUgly 21 Aug '07

21 Aug '07

I created simple gradient with 4 stops where the middle two stops were tight against each other to creat an instant jump from one colour to the next. This instant jump creates pixelation - http://www.microugly.com/images/misc/inkscape-pixel-gradient.gif Is this a known issue? It's strange to get pixelation in a vector application :) -- View this message in context: http://www.nabble.com/Pixelated-gradients-tf4304604.html#a12252881 Sent from the Inkscape - Dev mailing list archive at Nabble.com.

Hi! It seems that there is a preview redraw problem in the PDF import dialog. When I list the pages, the preview seems to cumulate the images (the next page preview is drawn on top of the previous page preview). See attached screenshots of the problem (PNG, 38Kb) I'm using Inkscape0708210339 on Win XP SP2. Molumen
