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?

Re: [Inkscape-user] pixel sizes

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 . '.jpg'; print "writing $jpg_file\n"; open(JPG,">$jpg_file") or die "error opening file $jpg_file for output, $!"; print JPG $jpg[$i-1]; close JPG; } } close 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.
