I would really like to know how you can convert the colorspace of an svg file, I have exported a CMYK file exported from Illustrator but it has not retained its colourspace. AFAIK editing the xml colour tag in a text editor is the only way to get the svg file to include CMYK or spot colour info, please could you share your method of you do this. > > > > I agree, but CMYK is not covered in the svg > > standard.

Thanks John Culleton, My current work around is to do just that or in most cases I change the colourspace of the pdf (including and especially images) using moonshiner. It doesn't always not retain CMYK colour values for vector objects, it is an extra step I would like to avoid. I was wondering if anyone else has been successful in using Ghostscript to convert the colourspace of a PDF, but integrated into the export dialogue maybe as a plugin. Its a slight hassle to import an SVG file, update the CMYK info on each object,export to PDF, send the file to my local printer, do a proof print with them, change the colour again in Scribus, export to PDF. I guess I will just have to continue along this way of doing things, until I have figured out how to what I want myself :) Please forgive if this email looks odd, I'm still looking for a mailing list reader to respond to posts on the list.

Actually SVG does allow for proper CMYK, as does Inkscape. It is just that the export path we use (Cairo) does not support CMYK.

CMYK in PDF from Inkscape
by Judah 24 May '14

24 May '14

Hi all I have been using inkscape for a while now, my only problem has been a lack of native CMYK (and spot color) support for PDF's from Inkscape. I was wondering if there is way to get this piece of software (moonshiner.sourceforge.net) to work with Inkscape esp in the "Save as" pdf dialogue? I checked it with an old version of <adobe/> software I have and the resulting file is definitely in a CMYK color space.

Hi Nathan, sorry for the late reply, Im waiting to have it to reply. > Ok, the tangents do look correct. I think the problem is that you > need to find the osculating points on the curved path fillets. There > is a toy for this (called fillet-minion). See if that makes for nicer > fillets. You are ok, oscilating point is wrong. I surf into the 2GEOM toy filet-mignon, i do about but it give me the strange results pointed by Cale Gibbard in the #3 of this launchpad bug https://bugs.launchpad.net/inkscape/+bug/202751 Finaly i adopted the Cale solution in the same bug https://launchpadlibrarian.net/12692602/rcp.svg Soon I comit the new code. I have a extra problem related to time values on curves, I find that not straight lines have his time values based by his handles instead the distance along it. My cuestion is: Any way to know a point at a distance based time value? Sorry if not explain so well. Regards, Jabier.

Authoring a multipage document using Inkscape
by Steve Litt 14 May '14

14 May '14

Hi all, I have a 2 page document (an evaluation form), and because spacing was very important, I used Inkscape instead of LibreOffice, LyX, LaTeX, etc. This two page document must print on both sides of the paper, so I'd imagine it must end up as a PDF. http://sourceforge.net/projects/inkscape-pages/ seems to indicate that I can do this natively in Inkscape by installing a plugin. I'm a little worried ways that a plugin might affect my normal Inkscape usage. http://wiki.inkscape.org/wiki/index.php/Multipage itself indicates that Inkscape itself doesn't implement multiple pages, because the current SVG spec doesn't support it. http://www.inkscapeforum.com/viewtopic.php?f=5&t=519 reiterates that current Inkscape doesn't support multiple pages, and suggests I use two different Inkscape docs, and desktop publish them with Scribus. All I really need is a 2 page portrait letter-sized PDF, and I'll figure out how to print it duplexed. I have no problem with making two different Inkscape docs. I'm a little concerned about putting letter-sized SVG's into Scribus or LibreOffice or any other "container". Anyone have any ideas of the best way for me to make a 2 page PDF out of one or two Inkscape files?

Hi Nathan. I do a deeper look. ///////////////////////////////////////////////////////////////////// El mar, 13-05-2014 a las 03:40 +1000, Nathan Hurst escribió: 1) to my old astigmatic eyes the tangents do not look like they are > quite matched, are you sure you have the tangent code correct.

Maybe the problem is how far is the tangent handle from a node, but there isn`t a perfect way to determine, it depends from case. I use the nearest point to the tangent from a point placed at a half distance from the real knot filleting to the original cusp node. Here are some pics about how it works: http://sta.sh/28yrjqkdiw1 ////////////////////////////////////////////////////////////////////// 2) can you add fillets with smooth curvature variation (e.g. cornu > spiral, spiro, and I recall there being a 2geom toy that demonstrated > something like that). > /////////////////////////////////////////////////////////////////////// I see about it in power stroke code, I realy do the code but finaly removed, think isnt interesting in one curve path, because it increase the nuber of nodes of the resulting path because you need to pass the cubic values of the handles as points, because the incoming and outgoing curve need to be unchanged. This is my opinion but if anybody want to tell me about, i could change ;) Thanks Nathan for the feedback.

Hello, I compiled Inkscape on FreeBSD and I can't reproduce my problem there. So it seems to be in some code which only runs on Windows. Any hints?

Hi Nathan. > Fantastic work, Jabiertxo! Thanks very much > Something to think about: If you were writing the curve editing/handle > code from scratch, how would it work? Firts to the end: Not realy a code from scrach. it have a lot of code from Power Stroke, without this i couldent make this. Power Stroke store in a vector of Geom::Point the data of his knots, basicaly in the X coordente store the position in the line and in the Y coordinate store the distance from knot to original line in perpendicular. Also have acallback in node tool for handle updates on the original path. Whith this base i work the effect. The work in progres add new features to the original concept whith the feedback of suv, LiamW and ScislaC. I put the ended result: I need to store: Distance from Knot to path: Stored in the [Y] part. it determine how far is the knot to the path -configurable by LPE widgets- in poxels, from 0 in the same path, in away. this is because with some zoom knots hide nearly Nodes and need a way to move a bit. It reply your 3 question Hide or show knot: Knots only show in cusp nodes so [Y] negative values in symm nodes... make the knot invisible. Fillet or Chamfer: It also is handled by the [Y] part of the Geom::Point. The [Y] value can be an floor(double) or a floor(double)+0.0001. In case there is decimal part, the effect show as chamfer. If a knot radius is in mode flexible (green knot): Store in the X value of the pathvector (int)index_of_pathvector +(decimal)0.-1 point at this curve. the next curve radius is calculated by the phisical distande in previous. If a knot radius is fixed (red knot): It still store the value in X but is stored in pixels -whith unit conversions- and with a negative value for easy check. This knots are exactly the X value in pixels*-1 in both sides. > 1) to my old astigmatic eyes the tangents do not look like they are > quite matched, are you sure you have the tangent code correct.

Why? Replied. Thanks Nathan for the feedback. I send news soon whith the active points. Sorry for my english. Regards, Jabier.

text in export to pdf randomly garbled
by Ronald Klop 12 May '14

Hello, I have a couple of technical drawings which I convert from Microstation (.dwg) format to SVG using some third party software and from SVG to PDF using Inkscape. The SVG contains the text on the drawing in correct form, but the PDF has text garbled. It is displayed ok, but the text selection for copy-pasting is corrupt. It is reproducable and the result is constant for every run. If I use the --export-latex option than the .tex file contains the text in correct form again. Is this a known issue? I cannot find it in the bug database. I'm running Inkscape 0.48.4 and also tried the latest development binaries from your site. I reproduced this on Windows Server 2008 R2 Enterprise and Windows 7 Professional. Both 64 bits. I can provide a sample drawing, but need to anonymize it first. Regards, Ronald. -- Ronald Klop
