Hi i've only recently discovered Inkscape and found it very promising. However, there is a feature that i miss a lot: the possility to define a frame for text with 1) dynamic line wrapping and 2) "local" formating options (e.g to mix various types of fonts, to use bold, italic, superscripts, subscripts in the text etc.). I have looked at the list of requested features and i found several related entries (e.g. 863325, 1084658 and 1080623) some of them dating back to last year. But there seems to be very little response to these requests. Without this feature inkscape is not a real alternative for me, unfortunately. Do you plan to implement such a feature? thanks imre

I want to be able to turn a piece of text that has been scaled uniformly or non-uniformly, back to its original state. ie. as it was written. OK. Your changes allow this to be done with uniformly scaled text. So my original problem is solved. However, I do not understand what is happening with non-uniform scaling, and it worries me that it simply may be giving the wrong result. The simplest case is where the text is stretched or compressed with no vertical change. The present code changes the font size. Why? I just cannot find anywhere that this is the correct result. As far as I can see the font size should be the same after as before. XaraX1 operates in the way that I see as correct. It shows two windows for a text object. 1. The font size. 2. The Aspect Ratio which is Width/Height as a percentage. The AR is 100.00 for any font size as initially written. With non-uniform scaling. The new font size is shown and the AR goes >100 or <100% depending on the scaling. When a piece of text is reselected the new AR and the font size are shown. It is straightforward to set the AR to 100 and the font size to your original font size and you get the original sized text back. Inkscape cannot not do this. With horizontal stretching or compressing. With Xarax1 there is no change in font size no matter how much the text width is changed. This is consistent with font size based on letter height. With Inkscape the font size changes with the text width. I think this is wrong. I do not know the details of what the programs are doing but Xarax seems consistent with > > David Bergs idea of "A button "set as 100%" for height and width will then > > adjust the font-size according to the skewed/streched width or the height > > respectively.

I would leave skewed text further down the priority list since I ceratinly do not use it routinely and nobody else has chimed in with this as a need or problem. If I can get non-uniform scaling sorted I'll be happy. > > P.S.

outputting gradients

I agree with you in principle that it might be good design to have a whole different piece of software whose job was SVG->PS or SVG->PDF. However, as far as I can tell, Scribus isn't going to fill that role, and I'm not aware of any other project that will. Scribus isn't cross-platform, it has no command-line interface AFAICT, at the moment it does not do a very good job on SVG->PDF, and I don't see any signs that they consider it to be part of their core mission to act as an automatic behind-the-scenes SVG->PDF converter that other programs can use library-fashion. To me, it would be much more logical for such functionality to be in Inkscape, rather than Scribus; but then, that's easy for me to say, since I don't have the C++ skills or the time that would be needed to do the necessary work on Inkscape :-)

outputting gradients
by Ben Crowell 19 Dec '04

19 Dec '04

This bug http://sourceforge.net/tracker/index.php?func=detail&aid=984043&group_id=93… refers to a problem with outputting gradients to postscript. Is there any workaround for this problem? I'm trying to produce PDF output, and have been doing it by doing a Save As, followed by epstopdf.

Centering odd shapes
by Chris 19 Dec '04

19 Dec '04

Is there any way to center odd shaped objects? (A triangle for example) The current implementation seems to center on the bounding box rather than the average of the vertexes. This makes it impossible to properly center odd shaped objects. Unless I'm missing something? -- // Chris

fonts, converting Illustrator to Inkscape
by Ben Crowell 16 Dec '04

16 Dec '04

I have several hundred Adobe Illustrator files that I'm working on converting to Inkscape. Many of them contain text, generally in Helvetica-9 and -10. Inkscape changes these to Vera-9 and Vera-10, and compared to the corresponding Helvetica fonts, these are about 15% bigger. Now I'm looking at how to handle this conversion, and I want to do it once and do it right, because it's such a large number of files. Basically I have a lot of wishes, which I'm sure are not all mutually compatible, and I'd appreciate any advice on how to get as many of my wishes as possible to come true. The files are illustrations for some textbooks, which I do using pdftex. wish list: 1 The books can be edited and printed (by me or by other people) without using any non-free software or fonts. 2 The text in the figures is close to the size it used to be, and doesn't require too much hand-tweaking. 3 The fonts used in the text (Computer Modern and, presently, Helvetica) look compatible with the fonts used in the figures. 4 The resulting files can be edited on the screen in Inkscape, and they look right. 5 The files look good when people download the PDF and view them on the screen in Acrobat Reader on Windows. (I sell the books in print, and they're also free online as PDF files.) 6 The files look good when my printer prints them as illustrations in my books. 7 The next time I do a new edition, I don't get calls from the printer saying "We couldn't output your document, what's this goofy Vera font?" I also don't get 1000 printed books and then notice that some text was messed up on output. (It's scary, because we do direct digital printing, so a nice looking galley doesn't mean anything -- the actual printing is done on a different device.) So far, I've thought of a few possibilities, and I'm curious if anyone can tell me if they are less than optimal: method A: Write a little Perl script to convert Vera-9 to Vera-7.64, and Vera-10 to Vera-8.50. Output to EPS with the fonts converted to outlines. - accomplishes 1, 2, 4, 7 - doesn't accomplish 3, 5, and 6, because the outlined fonts render badly in PDF viewers and on printers method B: Like A, but don't convert the fonts to outlines. - accomplishes 1, 2, 4, 5, 6 - may accomplish 7, if I can get pdftex to embed Vera - may accomplish 3, but I haven't been able to test it; Vera appears much heavier than Helvetica, but this could be simply due to the limitations of rendering using method A method C Buy a proprietary Helvetica screen font for Linux. - accomplishes 2, 3, 4, 5, 6, 7 (Helvetica is one of the basic 13 fonts supported by all PDF viewers and PS printers.) mehod D Convert all the sans serif in the text from Helvetica to Vera, and get pdftex to embed Vera in the PDF. Don't have Inkscape convert the fonts to outlines. - accomplishes 1, 2, 3, 4, 5, 6 - may or may not accomplish 7...it would worry me

Perl script for gamma-correcting an SVG file
by Ben Crowell 16 Dec '04

16 Dec '04

Here is a Perl script I wrote for gamma-correcting an SVG file. It handles both line art (regular SVG stuff) and embedded raster images. You must have the ImageMagick "convert" utility installed. The present version lightens and color-corrects an SVG that was created on a Mac so that it looks right on a PC, but it could easily be modified to serve a more general purpose. Once Perl extensions are implemented in Inkscape, I can hook it in there, but for now you just have to run it from the command line. I'm guessing that the long lines are going to get mangled somewhat as this goes out via the mailing list; I'd be happy to stick this in the Inkscape CVS tree if people think that would be appropriate and if I knew where was a good directory to put it. I've only tested this on some of my own files. Please don't trust it blindly on your own files, and let me know if you encounter any bugs. ============================================================================================ #!/usr/bin/perl #---------------------------------------------------------------------------------------------- # gamma_correct_svg # B.

Thanks for the detailed response bulia. This is valuable stuff and I will have to ponder. But not tonight-I mean this morning. It is 12:17am here. I will be gone until next Tuesday so you can have some peace until then. Basically I'm very happy with the latest changes. I can now do what I originally could not but there are still these little points that I do not understand. regards, vellum

Importing and saving
by Andrew Conkling 15 Dec '04

15 Dec '04

Hi, I'm having a little trouble in 0.40. I'm working with taking an SVG, importing another (which renders correctly on its own), and saving it. If I do that, the gradients in the imported SVG do not save correctly and show up various shades of gray. However, if I rechoose the gradient from the list (the same one that it already is), and resave it, it then renders correctly. Is this a bug or expected behaviour? Thanks, Andrew

icon design
by Lars Boelman 15 Dec '04

15 Dec '04

Hi all, Even though I'm not an active user of Inkscape (yet), I do follow this mailinglist actively and enjoy the current discussion on interface design. There are certainly ways you can judge an interface, as one person pointed out would be hard or impossible to do. Asktog.com has some interesting suggestions for this on the page 'First Principles of Interaction Design' which can be found at http://www.asktog.com/basics/firstPrinciples.html I especially want to stress the importance of Fitts's Law in all graphical interfaces: http://www.asktog.com/basics/firstPrinciples.html#fitts's%20law http://www.asktog.com/columns/022DesignedToGiveFitts.html My impression of the Inkscape interface is that there's no real common sense about how to create the interface among the developers. I hope I'm wrong about this and that there are guidelines for developing for the Inkscape interface. There are several HIGs (Human Interface Guidelines) available for free on the web, who basically tell the same. I'm a real fan of the Mac OS X Aqua desktop environment and think that the Apple HIG are argumented very well. I'd suggest that at least some parts of the Apple and Gnome HIGs should be used as guidelines for developing the Inkscape interface and should be referred to (at least the useful parts of) at the software development documentation. This only is useful when all developers see the relevance of this and consistently apply it. To start with streamlining the interface, I want to suggest to take a look at what Apple and Gnome have to tell about icon design. Though they disagree on the style of icons, they do share a common thought on functionality and consistency. Apple: http://developer.apple.com/documentation/UserExperience/Conceptual/ OSXHIGuidelines/XHIGIcons/chapter_5_section_1.html#//apple_ref/doc/uid/ 20000967 (that URL is far more user-unfriendly than the text itself fortunately) Gnome: http://developer.gnome.org/projects/gup/hig/2.0/icons.html I hope my suggestions were of any use, though I hope even more that it was old news...

An alternative would be to add gradients via bitmap editing. The only drawback is that it is not possible to access single objects anymore. A workaround could be to export as .ai, to convert the file to .psd (Photoshop), and then to re-import it into the Gimp. I haven't tried this yet, though, still working with v 0.39.

Regarding user-friendliness: I have used CorelDRAW in the past, and the interface of Inkscape is IMHO much more user-friendly & the layout in general is much "clearer". I agree that the palettes could be improved, but in general I am regarding this criticism as way too strong (and somewhat unfair). As I suggested already, docks would be nice, but otherwise I personally find Inkscape very user-friendly. One thing that could be better is, that when I open a file, a new Inkscape window appears, so that I have to close the previous one first. Claus -- http://home.arcor.de/ccyrny/

Anti-aliased PNG Output
by Elpoca 14 Dec '04

14 Dec '04

Hi: I'm using Inkscape 0.40 on Windows. Is there any way that I can make the output anti-aliased? Right now, if I do an 'inkscape -e file.png file.svg' the output looks very poor. If anti-aliased output is not possible, then can anyone suggest a technique to convert my svg to high-quality png? I've tried batik, but the output is also very poor. FYI, it renders fine in both Inkscape (indeed, it was created using inkscape) and in the adobe SVG viewer. Thanks, Elpoca

Re: script for embedding raster images
by Ben Crowell 14 Dec '04

>> Can anyone try this and tell me if they understand what's >> going on? >Have you compared your output syntax with share/examples/data_uri.svg? Aha! Adobe Illustrator does this: data:;base64 But, as shown in the sample file, Inkscape wants data:image/png;base64 or data:image/jpg;base64. I've fixed the script to write it the way Inkscape wants it: http://www.lightandmatter.com/embed_raster_in_svg The latest CVS version of Inkscape is now happy with the script's output. I don't know if AI's output is standards-compliant in this situation or not. Presumably when AI reads one of its own SVG files, it just looks at the magic number from the data in order to figure out what type it is. (There are only two possibilities.) If omitting the type is legal according to the SVG standard, then maybe Inkscape should allow it on input. >P.S. If you plan to keep contributing to Inkscape I can give you >developer access That would be nice, thanks! Given my weak C++ skills and lack of familiarity with Inkscape's codebase, I probably wouldn't dare to committ changes to the C++ code on my own, except maybe after getting comments on them. But if the plan is to have an Extensions menu that can call various Perl scripts, then it might be nice for me to be able to contribute directly to that. My Perl skills are a lot better than my C++ skills, and I'm going to need to write various scripts anyway for my own use (e.g., I'm going to need something to gamma-correct svg files). Is there an API for extensions?

Re: postscript output is rotated 90 degrees? (bulia byak)
by Ben Crowell 13 Dec '04

13 Dec '04

Thanks, Bulia, for applying the patch! I'd like to request the following further patch. You made w and h doubles, rather than ints, which makes sense, but the fabs is incorrect, because we have w<0 or h<0 on an empty document (I think they're -200000000 or something). That's why there is the sanity check later on. 361,362c361,362 < double w = fabs (d.x1 - d.x0); // width and height of bounding box, in points < double h = fabs (d.y1 - d.y0); --- > double w = (double) (d.x1 - d.x0); // width and height of bounding box, in points > double h = (double) (d.y1 - d.y0); 364c364 < ((int) w > 0 && (int) h > 0) // empty documents fail this sanity check --- > (w > 0. && h > 0.) // empty documents fail this sanity check, have w<0, h<0

script for embedding raster images
by Ben Crowell 13 Dec '04

13 Dec '04

As Bulia suggested, I've written a Perl script that takes an svg file that links to bitmapped images, and embeds the images into it. The script is here: http://www.lightandmatter.com/embed_raster_in_svg It can be tested using these two files: http://www.lightandmatter.com/beer.svg http://www.lightandmatter.com/beer.jpg Download all three files, then run the script like this: embed_raster_in_svg beer.svg It copies the original version of beer.svg to beer.svg.bak, and then embeds the raster images into a new version of beer.svg. The output looks reasonable to me, but I'm having a hard time figuring out if it's valid Inkscape svg or not. Bulia said the latest version of Inkscape could handle embedded raster images, so I checked out a copy from cvs, compiled it on my machine, and used it to open the version of beer.svg with the image embedded. However, it showed up as a broken link, just like in older versions of inkscape. Can anyone try this and tell me if they understand what's going on?

Hi, > I'm very happy with Inkscape's features, but missing one: > How can I switch view to pixel 1:1? Why, you can use "Zoom 1:1", which displays the image in the actual pixel size. Just click on the magnifying glass, and then you have the option "1:1" in the menu bar at the top (at least up to v 0.39). Claus -- http://home.arcor.de/ccyrny/

script for extracting embedded jpeg images
by Ben Crowell 12 Dec '04

12 Dec '04

The following is a Perl script I wrote for extracting jpeg images that are embedded in an SVG file. I thought it might be useful to some other people. Adobe Illustrator writes SVG output with jpeg images embedded in it. Please correct me if I'm wrong, but AFAICT Inkscape handles <image> tags just fine if they link to an external jpg, but doesn't handle the case where the jpg is embedded. ====== #!/usr/bin/perl # usage: # extract_jpg_from_svg foo.svg # extracts an embedded jpg to foo.emb.jpg (or foo.emb1.jpg, foo.emb2.jpg, ... # if there is more than one) # SVG files generated by AI may have JPEG images embedded in them that look sorta like # this: # <image width="554" height="412" id="XMLID_13_" xlink:href="data:;base64,/9... # The /9 is guaranteed to be there because the magic number of a JPEG file is ffd8 at # a zero offset into the file. use strict; use MIME::Base64; undef $/; # slurp whole file my $svg = $ARGV[0]; die "input file $svg not found" if ! -e $svg; die "input file $svg not readable" if ! -r $svg; open(FILE,"<$svg") or die "error opening file $svg for input, $!"; my $data = <FILE>; my @jpg; my $n = 0; while ($data=~m/\<image\s+(\w+\=\"[^"]*\"\s+)*xlink\:href=\"data\:\;base64,(([0-9a-zA-Z\+\/]|\s)+\=+)/g) { my $base64 = $2; if ($base64=~m@/9@) { my $binary = decode_base64($base64); if ($binary=~m/^\x{ff}\x{d8}/) { push @jpg,$binary; ++$n; } } } if ($n==0) { print "no embedded jpgs found in file $svg\n"; } else { for (my $i=1; $i<=$n; $i++) { my $jpg_file = $svg; $jpg_file =~ s/\.svg$//; $jpg_file = $jpg_file . '.emb'; if ($n>1) {$jpg_file = $jpg_file . $i}; $jpg_file = $jpg_file .

"How do I..." questions
by Andrew Conkling 12 Dec '04

12 Dec '04

Hi, I just started using Inkscape to help out with an icon theme I've come to like. I just upgraded to 0.40 and found it to be immensely more usable; great job! But I'm no doubt still a noob.... I was wondering if the following hangsup I've run into are possible. Help on any of them would be much appreciated: 1. I made 3 Bezier curves that I want to intersect into a shape, but when I try to change the fill for them, it changes on the outside of the shape. Is there any way to change that, or to have Inkscape recognise the 3 curves as a shape in its own right? 2. I'm in Linux, using librsvg 2.8.1, but one icon that looks fine in Inkscape doesn't render properly in the various applications I have viewed it in (it's an icon). What issues could be at work here? 3. Is it possible (again with the Linux version) to theme the icons on the toolbars? Like I said, I'm working to help an icon theme and it would be supremely cool if we could theme Inkscape. Kind of a hat-tipping to the program that helps us make good icons all around.... :) Thanks in advance, Andrew Conkling

RE: [Inkscape-user] pixel sizes
by Robert G. Davis 12 Dec '04

I think this is what I was talking about a while back. An imported bitmap sizes in inkscape apparently as SVG points. Bring up a bitmap in gimp and 1:1 it and 1:1 the same bitmap in inkscape. The inkscape bitmap is smaller. It displays correctly if I view the svg in Illustrator. This also affects exporting bitmaps. One way I work around it is to size the SVG width/heigth to the correct size. Not perfect.
