Re: [Inkscape-user] Exporting a pdf with an Inkscape generated png

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?

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.

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

Prezi-like functionality
by Arnout Standaert 12 Mar '09

12 Mar '09

Hi list, Probably some of you have already seen Prezi, an web application for "non-linear" presentations. That doesn't sound too clear, but see http://www.prezi.com for an example, or http://www.aether.hu/prezi for an introduction. It basically breaks the traditional slide-show format of presentations and turns it into a fancy dynamic flight-simulator-like concept. Very refreshing and ubercool after years of Powerpoint slides :-) As far as I know, there is currently no other software doing something like this. But IMHO, Inkscape would be very much suited for this. Currently, it has the ideal editing tools to compose the presentation material itself, but it lacks the animation interface to provide the navigation and zooming aspect in the presentation itself. With all the SVG animation plans, Prezi-like presentations would seem to be within reach. My question: are there tools/applications available that provide the zooming/path-based animation functionality for Inkscape-produced SVG files? Or can this be done using Inkscape itself and scripting (Javascript?)? I suppose the latter would come down to hand-coding and building a lot from the ground up, or are there tools available that can help with that? Opinions and suggestions appreciated, wwwald
