CMYK-safe color maps.
by john Culleton 05 Oct '11

05 Oct '11

In Inkscape one can arrive at CMYK-equivalent colors but only if one of the four CMYK factors is zero. Is there any of the standard Inkscape palettes that contains only colors that are convertible to CMYK without significant color shift? I can build my own but this will be extremely tedious. -- John Culleton Wexford Press "Create Book Covers with Scribus" http://www.booklocker.com/books/4055.html

interpolation issue in Inkscape
by Florian Berger 03 Oct '11

03 Oct '11

Hi Inkscape community, I have an issue with unwanted / inferior looking interpolation in scaled Inkscape PNG exports. In the case at hand I have a pixel art image that has been converted to SVG using 40px x 40px vector squares for each pixel (whether or not Inkscape is the right tool for playing with pixel art is *not* the question here ;-) ). When such an image is scaled down a little and exported as PNG, it shows some poor interpolation artefacts. These artefacts are less obvious or not present in the actual Inkscape display, but very visible after export. Here is an illustriation of the problem: http://img594.imageshack.us/img594/769/inkscapeinterpolation.png (Please view at original size first to prevent additional interpolation.) Please note that some of these interpolations do not seem to make sense, e.g. using bright grey in the brown / dark red hair of the character. I am very aware that Inkscape may not be the weapon of choice for this kind of operation. Still, my questions: - Is there any way to prevent Inkscape from interpolation / anti-aliasing upon exporting such an image? - If this is an interpolation issue: why does Inkscape use such inappropriate colors? - Shall I file a bug? :) Any hint will be appreciated. Thanks, Florian

Linux laptop/tablet PC for running Inkscape
by Philip Durbin 03 Oct '11

Hello! I'm interested in using Inkscape with a stylus on a touch screen and I'm heavily influenced and inspired by articles I've read about Máirín Duffy's use of a Thinkpad x61 to create illustrations for Red Hat: http://blog.linuxgrrl.com/2009/11/08/fedora-12-rocks-on-tablets/ http://mairin.duffy.usesthis.com/ I'm not sure what I would do with Inkscape exactly, maybe make a webcomic as I hinted about here: http://www.webcomicalliance.com/helpful-hints/mac-vs-pc-the-webcomics-editi… . For now, I just want to doodle a bit. Anyway, following Máirín's lead, I guess I'm thinking about buying a Thinkpad X Series Convertible Tablet. As of this writing the model that's available is the X220, but I'm not sure how well it works with Linux and Inkscape. Lenovo doesn't ship the device with Linux pre-installed: http://www.lenovo.com/products/us/laptop/thinkpad/xtablet-series/index.html I'm open to other hardware suggestions. On the market right now there's an HP EliteBook 2760p Tablet PC and a Dell Latitude XT3 Tablet PC as well. Basicially, I'm looking for something that will run Linux and Inkscape and let me draw on the screen itself rather than using a Cintiq. Is this a common hardware setup for Inkscape users? Can anyone recommend what device I should buy? I've been using Linux on the desktop for five years (usually something Red Hat-based) but never on a laptop. Thanks! Phil

Re: [Inkscape-user] CMYK-safe color maps.
by gespertino＠...155... 30 Sep '11

I know this isn't a very scientific method, but still :-) I'd import the color map to inkscape or GIMP and use the gamut warning to "mask" out of gamut colors. then capture the "masked" palette, then re-create the palette using the captured values. CMYK-Safe colors depend on the output CMYK profile, so it's probably impossible to have a generic "safe" palette without using a specific profile as starting point. I'm pretty sure this isn't the best way to do it (there has to be a programatic way to do it using RGB and CMYK profiles to compile a palette, but I don't know how to do it). IIrc the program Swatchbooker allows to choose profiles to "convert" palettes, but I could never make it work. hth, Gez

Distorting text.
by john Culleton 15 Sep '11

Came across a string of text on a book cover where the first letter leans to the left, the last leans to the right, the middle character is upright and all the others have a lean dictated by their location with respect to the left or right end points. What filter should I be looking for? -- John Culleton Wexford Press "Create Book Covers with Scribus" http://www.booklocker.com/books/4055.html
