Logo for SVG Open 2009
by Jon A. Cruz 28 Mar '09

28 Mar '09

Hello all, I just wanted to put out that SVG Open 2009 is looking for header graphics for their new website... which is about to go live. SVG Open 2008 had a subtle header with outlines of the castles in Nuremberg, so is probably not good for this year's conference in California. If anyone is interested, this is a great opportunity to showcase both SVG and Inkscape. I believe that the site will be able to serve SVG directly for browsers that support it.

How to make a mask?
by Paul Bolger 23 Mar '09

23 Mar '09

I've been trying to work out how to produce a mask, to be used for compositing an image with ImageMagick by a CMS. What I need is a white background and a rounded border (with a stroke of one or two pixels), then with the middle punched out so an image on the layer below shows through the hole. I've tried making three layers, one solid white, one with a rounded rectangle with rounded corners with a transparent fill, and a copy of the previous with no stroke but with a solid fill, and tried various combinations of 'mask' and 'clip' but I can't seem to find it. Can someone help me before I resort to chucking it into Photoshop and cheating? Paul Bolger

Re: [Inkscape-user] Exporting a pdf with an Inkscape generated png
by Matt Jordan 22 Mar '09

Thanks to JiHO, bulia byak, and minombresbond for responding. I'm replying to the digest so please forgive me if I address all responses at once. In a nutshell, the latest version of Inkscape does in fact work very well for rasterizing blurs and including them in pdfs at the proper resolution. The only issue I ran into when I did a test print this afternoon was that the rasterized blurs gave off a bounding box effect when printed that didn't show up (to my eye, at least) when the pdf was viewed on screen. The bounding box effect was, specifically, a discoloration of of the background under or behind the bounding box. Is there some setting or technique for eliminating this effect? If so, then this approach would work beautifully for getting what's on screen onto the printed page. My back-up approach will be to output pngs and then use Scribus to layout the cover (though I'll probably skip the CMYK step suggested by minombresbond since Amazon's POD service apparently doesn't require CMYK). And, to answer JiHO, I have both Ubuntu Linux and Windows XP available. I prefer Ubuntu, but do some of the color work on the XP box because it has a superior monitor. (My Ubuntu is on a laptop with a so-so lcd monitor.) Anyway, thanks again for the help. Matt Jordan

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

Exporting a pdf with an Inkscape generated png
by unknown＠example.com 19 Mar '09

Hi, I'm using Inkscape to create a book cover that'll be published through Amazon's CreateSpace service. CreateSpace requires a pdf. I can output my Inkscape svg as a beautiful pdf except for one thing: I'm using a few blurs in the book cover and, of course, they don't render correctly. So I thought about outputting the whole cover as a png (which renders everything correctly, including blurs), importing the png back into Inkscape, and then outputting that as a pdf. I figured that, going that route, I'd need the png to be of sufficient size so that it'll print correctly at 300 dpi - since the png is no longer vector. So, is there a way to "tell" the resulting pdf to use my gigantic 2400 x 1575 pixel png but fit it in an 8 x 5.25 inch document? Thanks, Matt Jordan ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Google's Summer of Code 2009 - Let's take the bull by the horns!
by Joshua A. Andler 19 Mar '09

19 Mar '09

Hey all, I just received word that Inkscape has been selected as a mentoring organization for Google's Summer of Code (GSoC) 2009. Let's make our fifth year, the best yet! Will any potential mentors quickly chime in so we have an idea of who wants to participate this year? As things have been before, we will have to request the number of slots we would like. Knowing that, the sooner we can get a feel for how many people want to mentor, the better. This would also be a good time for any potential student participants to start putting together their proposals. For reference, our wiki page containing information and ideas about GSoC 2009 is at: http://wiki.inkscape.org/wiki/index.php/Googles_Summer_Of_Code_2009 As of this point, any and all interested community members are encouraged to take a look at that page and help to improve or add proposal ideas. Thanks everyone, we wish all participants good luck at making this another successful Summer of Code! Cheers, Josh

PNG output is not anti-aliased well
by Sagara Wijetunga 16 Mar '09

16 Mar '09

Hi We are the makers of the Tomahawk Desktop operating system (http://www.tomahawkcomputers.com/). We use Inkscape (ver. 0.46) to create all of our vector graphics. Certain graphics we created are not sharp, ie. not anti-aliased well. Please see following graphics: http://www.tomahawkcomputers.com/bsd-unix.html http://www.tomahawkcomputers.com/real-time.html http://www.tomahawkcomputers.com/images/real-time-small.png The source of the clock is from Oxygen icon set: actions/chronometer.svgz What could be the issue? Is there some settings to make somewhere? Or is it a known issue to be fixed? Best regards Sagara

editing freehand
by Hendrik Boom 16 Mar '09

16 Mar '09

I often draw a wiggly line, then realize that it's not quite right, and I'd like to redraw part of it. Ideally, I'd mark a part of it to be replaced, and then free-hand draw another pieve of wiggly line to replace it. Now the only way I've found to edit an existing line is by adding and removing control points and turning the tangents -- far too cumbersome for what I'd like to do. Is there any way to accomplish what I'm trying to do? To edit a portion of a line freehand? -- hendrik

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.
