SVG Version 1.2 vs 1.1
by Bernhard Kleine 29 Jan '18

29 Jan '18

Hi, I encounter problems with the Oxygen XML editor due to the fact that the SVG inkscape produces are Version 1.2 which the Batik renderer can not fully parse since it does only use SVG Version 1.1. The easiest way to solve the issue would be to restrict inkscape saving to Version 1.1. How can I achieve this?

Chromatic Aberration Filters Proposal
by Fabien Fellay 29 Jan '18

29 Jan '18

Hi all, I released some filters that allow emulating a very basic chromatic aberration effect. They are available here with some explanations: < https://inkscape.org/da/~fabien.fellay/%E2%98%85chromatic-aberration-filters > They come with some animated examples as well: < https://inkscape.org/en/~fabien.fellay/%E2%98%85chromatic-aberration-rgb-cm… > < https://inkscape.org/en/~fabien.fellay/%E2%98%85chromatic-aberration-rc-cr-… > < https://inkscape.org/en/~fabien.fellay/%E2%98%85chromatic-aberration-with-r… > I later noticed that Inkscape already has similar filters available in the menu Filters > Color > Nudge RGB/CMY... However, the proposed filters here differ slightly regarding the alpha channel management and they do not flood the background with any color. If one just want to apply quickly a basic chromatic aberration effect, I think those filters may come in handy. In the hope that someone will like them or find them useful. Best regards, Fabien

Reusing similar images/vectors across multiple projects
by Kale Good 24 Jan '18

24 Jan '18

Hello, My use case is this: I want to use inkscape to annotate my pdf music scores. Basically "highlighting" stuff different sections and adding text, etc for performance directions. One thing I'd like to be able to do is quickly and easily add common musical symbols (examples here: http://lilypond.org/doc/v2.18/Documentation/notation/the-feta-font#dynamic-…) (I'm not sure why the heading is "Feta Font" and then it mentions "Emmentaler font"). The example show is already on my system and open-source. I have SVG font files files (which I've never used and aren't showing up in my Character Map software) and .otf (I think; or some other common font format) files. Additionally, I can have the music program export each character/musical symbol as an individual SVG. I thought the easiest way to do this would be to use a character map application. On inspection, that seems to be less than optimal to say the least (the fonts that lilypond uses seem to be spread through about 10 different font files, and may fields are empty. I have a very, very hard time finding them there). It seems like it would be easier to memorize the 30-50 utf encodings + the specific font name (is it emmenalter-15 or emmenalter-16?) than using that. And, obviously that isn't easy. Additionally, some font characters often appear together (for example, the symbol for /forte, f/ often appears with an /m/ in front of it as a modifier), and that just adds some complexity. The other solution I think may be useful for other, more common use-cases; however, I can't seem to find any implementation of it. So, barring some unforeseen solution there, I think the better option is this: to have some sort of "bank" or "library" docked tab that I can add the desired symbols/shapes to. Then I can just drag and drop these into different projects (this would probably involve having lilypond export each desired symbol, opening the resulting SVG file in Inkscape, and copying each vector into the "library"). Does this functionality exist somewhere that I'm just missing?

One metre interactive grid (long lat) superimposed on a map
by Philip Rhoades 20 Dec '17

20 Dec '17

People, I have done a bit of Googling but am a little overwhelmed about where to start but I thought Inkscape people might have a better idea. I want to add an interactive 1 sqm grid to the attached plan. I have the original as a SVG file but it is too large to attach - I imported it from a PDF file for use in Inkscape. I want the grid to be square with longitude and latitude (maybe the maybe should be rotated) such that people could click a rectangle of squares to indicate a proposed new building lot on the site. Is SVG the right tool to build such an interactive map for a web page? Thanks, Phil. -- Philip Rhoades PO Box 896 Cowra NSW 2794 Australia E-mail: phil@...2067...

Survey: Default beabiour on clones with path operations
by Jabier Arraiza 16 Dec '17

16 Dec '17

Hi all: I just commit a branch [1] that convert shapes and optinaly clones to paths previously any of this path operations: Booleans, Stroke to paths, Object to paths, Combine and Break Apart. The cuestion is simple: ¿Whats is your prefered option about symbols? This is done in preference section and can be change by the user, but we are speaking about the default behabiour. A: Convert to path clones and apply the operation B: Retain clones in this operatios ignoring the operation Thank for take time to reply. [1] https://gitlab.com/inkscape/inkscape/merge_requests/159

Spin slider widget, redux.
by Tavmjong Bah 15 Dec '17

15 Dec '17

Hi all, I've taken into account all the feedback and have developed a little test program that shows of a number of solutions to replacing the Gimp Spin Scale widget. A gzipped tar file of the source code is attached so that you can try out the solutions (should be trivial to compile on Linux if you have the Gtk3 libraries). Not all of the solutions fully work as I didn't take the time to make them... but you should be able to get a feel for them. If you run in debug mode (see README) you can interactively add CSS. I've include an example CSS file you can paste into the debug window (ignore the colors, they were just for experimenting). I've also attached PNGs of the widgets with and without the extra CSS. The five solutions, from top to bottom, are: * Custom Gtk::Range widget couple with Gtk::Spinbutton: This is my current favorite. It works quite well, methinks. Use the 'Alt' key to get into fine adjustment mode. It was rather simple to implement. Could be refined further (add styling properties, rounded corners, etc.). * Gtk::Scrollbar coupled with Gtk::Spinbutton: Works rather well, but doesn't show as well the current value. Using a narrow "slider" prevents it from covering up the text (text not implemented yet). I didn't know it before, but if one clicks on the slider and doesn't move for a second or two it enters into a fine- adjustment mode. * Gkt::ProgressBar coupled with Gtk::Spinbutton: CSS can get this looking pretty good but some extra work has to be done as the ProgressBar doesn't have an "adjustment", the class that actually handles tracking a value. The Gtk::Spinbutton actually contains a ProgressBar but while one can style it via CSS one can't directly access it and it overlaps the numerical entry part of the SpinButton (this is how the Gimp widget works). * Subclassed Gtk::Spinbutton: This is essentially a modified version of the Gimp widget but it has some major flaws as one cannot access the underlying widgets (ProgressBar, Buttons). In this example, the built in ProgressBar is disabled and new code that simulates a narrower ProgressBar has been added. I could not fine a good way to calculate how much narrower the new bar needs to be to not overlap the numerical entry part. Also, when dragging the bar it is easy to highlight the numerical text. The code to do all this is pretty messy. * Gtk::Scale coupled with Gtk::Spinbutton: CSS can make this look reasonable. Reducing the size of the circle will prevent it from covering text (text not implemented yet). Gtk::Scale also has a fine-adjustment mode accessed the same was as for a scrollbar. Tav

Display and User units, Scaling, Measuring Paths, Importing PDF
by Philip Rhoades 05 Dec '17

05 Dec '17

People, If I produce a new drawing on an A4 page with Display and User units in mm with a scaling factor of 1.0, I can draw a rectangle of XxY and when I use the Visualise->Measure Path Extension with a Scale Factor of 100 and Length Unit in m - I get exactly the right dimensions for the rectangle for its perimeter length and area - all good! However, I have imported a surveyor's map from a PDF file into SVG and I need to be able to draw rectangles on it as above in mm (like my test) that will correspond to m in the real world but the drawing is on an A1 page and the Display and User Units are in px and I have tried everything I can think of and Googled a lot but I can't do what I was able to do with my little test case. So: How can I convert the drawing to be on an A4 page with mm units so the mm correspond to m and the Measure Path Extension will give me the correct result in m and sqm? The original PDF says the scale was 1:300. Thanks, Phil. -- Philip Rhoades PO Box 896 Cowra NSW 2794 Australia E-mail: phil@...2067...

Spin slider widget: Opinions needed!
by Tavmjong Bah 05 Dec '17

05 Dec '17

Hi, I've been looking into replacing the Gimp Spin Slider widget (e.g Blur/Opacity in the Fill and Stroke dialog). The widget is licensed under GPLv3 and is the only reason Inkscape as a whole is licensed under GPLv3 rather GPLv2.. The board sometime ago agree that being a GPLv2 program was desirable (I don't remember the exact reasoning). A normal Gtk Spin Slider (aka Gtk::SpinButton) has an option to show the "progress" of slider, that is the percentage (defined in some arbitrary way) between a minimum and maximum value. This in Gtk 2 is shown as a solid blue bar with width proportional to the value that covers the widget from top to bottom. In Gtk 3 the solid blue bar is replaced by a thin blue bar at the bottom of the widget. As far as I can tell, the Gimp version of the slider makes three changes: 1. It allows for a label inside the widget. This is a nice space saving feature. The widget handles changing the label text from black to white as the progress bar moves across the label. 2. It allows for a non-uniform scale by adding a "gamma" factor. 3. It adds the ability to drag the progress bar to change the value. If one drags from the top (down arrow cursor) the change follows the cursor directly. If one drags along the bottom half (double headed cursor) the change is finer and relative to the current value. I've always found that dragging the progress bar to be a bit awkward. One problem is that one can not start the drag at the far right of the widget as that area is reserved for typing a value directly in. Also, the different functionality of starting the drag in the top of the widget vs. the bottom of the widget is confusing. Since I am rewriting this widget, I can adjust it to what people want: * Do you want the progress bar? * If so, should it be the full height of the widget (quite a bit more complicated)? * Do you want to be able to drag the bar? With one/two methods? * Any other changes? Thanks, Tav
