Call for help: Screenshots needed for 0.46
by bulia byak 20 Mar '09

20 Mar '09

As we're nearing the release, we need more screenshots to show off the new features in 0.46, to be published at http://inkscape.org/screenshots/index.php?lang=en. Here's a page describing how to create good screenshots: http://wiki.inkscape.org/wiki/index.php/MakingScreenshots. Use the information on that page and the best of the existing screenshots in our gallery as inspiration. At the very least, we need to illustrate: - 3D box tool - SVG filters - more live path effects (we only have one screenshot for path along path) - gradient tool's on-canvas mid stops - a (meaningful) illustration of the color management at work - new extensions - new grid and guide features - perhaps something with custom markers, along the lines of http://needcoffee.deviantart.com/art/Gradients-To-Path-78650259 - any complex, stunning, impressive Inkscape art even if it does not use the new features :) See the release notes for a list of all new features: http://wiki.inkscape.org/wiki/index.php/ReleaseNotes046 You can send your submissions to me for publishing on the site. Thanks in advance! -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Re: [Inkscape-user] Extracting formulas from curves?
by Philip Rhoades 16 Mar '09

16 Mar '09

Felipe, I have a statistical relationship in mind and I find it is convenient to use Inkscape to create the graphs of what I think it should look like under different conditions. Having done that, it would be nice to be able to extract the formula for each curve that I have drawn. The curve of the relationship that I am thinking of should have only a single y value for each x coordinate, so it should be a function. Thanks, Phil. > From: Felipe Sanches <felipe.sanches@...2592...> - 2009-01-30 02:02 > well.. maybe. > it is a bezier curve.

eraser tool opinions?
by bulia byak 15 Mar '09

15 Mar '09

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 Alt, Inkscape subtracts the path you have created from the selected path (with Shift, 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? -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Iconset
by Plácido Sousa 01 Mar '09

01 Mar '09

Hi all, I've been improving (I think!) the inkscape iconset (work in progress). I've resized and simplified some of the icons to make them look better in my Linux distro (Ubuntu 8.10 - haven't tried others). If the feedback is positive I'll try them in Microsoft Windows to see what I can do! (Sorry! I don't own a Mac) SVG file - icon.svg - and a screenshot as an attachment. bye -- > Plácido André Sousa http://chezplacide.blogspot.com placidoaps@...155... .-. /v\ L I N U X // \\ >Phear the Penguin< /( )\ ^^-^^

why doesn't this work?
by Elwin Estle 25 Feb '09

25 Feb '09

I am trying to make a simple wedge shape that is 1/6 of a hexagon. So I used the polygon tool to make a hexagon. I convert it to a path. I duplicated it, shrunk it down some and used a boolean operation to cut a smaller hex shaped hole in the exact center of the larger hexagon. Then I used the node tool to select the extraneous nodes and delete them. Now I have two lines, both part of the same path, but not connected. When I select two end points on the lines and try to join them with a new segment, I get an error saying I haven't selected two nodes!!! So just for the heck of it, I used the bezier tool to make two separate lines, combined them to a single path and then tried to connect two end nodes with a new segment. Worked just fine. I could try to do the shape I am after this way, but getting everything positioned right might be something of a pain. I am just wondering why the first technique doesn't work. Seems like it should...

Remove Object Fill and Stroke in Palette
by Plácido Sousa 20 Feb '09

20 Feb '09

Hi, In some programs I remember to see a "color palete" (white with a red cross) to remove the color of object Fill or Stroke. Is there a similar thing with Inkscape? -- > Plácido André Sousa http://chezplacide.blogspot.com placidoaps@...155... .-. /v\ L I N U X // \\ >Phear the Penguin< /( )\ ^^-^^
