SVGMatrix deprecated?
by Steve Litt 25 May '17

25 May '17

Hi all, I have a bunch of groups of class "screw", each comprised of a circle screwhead and a smaller square in the center called a screwsquare. In every instance of "screw", screwhead and screwsquare have identical x, y, height, width and r dimensions. Each screw's position is determined by the screw group's transform=translate(xadjust, yadjust). This is done automatically by Inkscape, and furthermore, it's easy to set manually with: myElement.setAttribute('transform','translate(xadjust,yadjust)'); The trouble comes in when you want to *get* that transform. Getting the transform is necessary when you want to move element whatever2 in relation to the location of screw1. Getting the translation is one of the worst documented things I've seen, but the concensus seems to be something like the following (for my screw case where the group has the transform): =============================================================== function screw_coords(screw){ matrix = screw.transform.baseVal.getItem(0).matrix; var coords = []; shead = screw.querySelector('.screwhead'); coords[0] = shead.cx.animVal.value + matrix.e; coords[1] = shead.cy.animVal.value + matrix.f; return(coords); } =============================================================== The preceding is ugly and fragile for a whole number of reasons, it's inobvious and horribly undocumented. But the real problem is it appears to be deprecated: https://developer.mozilla.org/en-US/docs/Web/API/SVGMatrix The preceding article says not to use SVGMatrix, and to update code as soon as possible, but remains mute on what you use instead. How the hell do you read a translation? It's a mystery. The following article gives a crazy train regex kludge method to read a translate: https://stackoverflow.com/questions/10349811/how-to-manipulate-translate-tr… If anybody knows the proper secret handshake to read a translate in a non-deprecated, browser independent, non-kludgificent way, please let me know, perhaps with some URLs of docs for such a functionality.

Manuals: Inkscape Beginners' Manual ready for translation to English and editing
by Maren Hachmann 17 May '17

17 May '17

Hi everyone, join us for translating and editing the Inkscape Beginners' manual, which is based upon Elisa de Castro Guerra's French book "Initiation à Inkscape" (Original French version available at https://www.flossmanualsfr.net/initiation-inkscape/ - don't translate this one ;-) ) ! Thank you, Elisa, for sharing your work and helping with licencing (also for joining the admins)! The plan is to translate the book from French to English (Sylvain and Hinerangi already did some of the work), and make adjustments as we see fit, then to make it available for people who only start using Inkscape - if possible, accessible directly from inside the Inkscape program. Here are some notes to get you started (we may tweak processes later, if we find better ones): Platform usage ============== This book is written at flossmanuals.net, which is a website that allows for collaborative editing of books about Free/Libre and Open Source Software. To learn more about the community that's behind it, please visit http://www.flossmanuals.org/about-floss-manuals-foundation. The manual for this 'manual writing platform' (which is an instance of the Booktype software), is available at http://sourcefabric.booktype.pro/booktype-16-for-authors-and-publishers/ . Joining ======= Join the group at http://write.flossmanuals.net/groups/beginners-manual-for-inkscape/ :-) Also say hi on the docs mailing list (see below, section "Communication", so we know who is who, and what you can help with. Editing ======= IMPORTANT: When you're editing the book, ALWAYS leave a screen either by clicking on the 'Cancel' or on the 'Save' button. This is because, if you leave it by just closing the tab in your browser, the chapter will stay locked and inaccessible for other editors. Version ======= This book will refer to the Inkscape 0.92.x series (important for your screenshots!). Writing Style ============= This book is meant as an introduction for people who are not yet familiar with Inkscape terminology. When deciding how to phrase something, think of yourself when you started to use a vector editor, or think of a teen who you would like to introduce to the program, and who you would like to enjoy the process, and to be able to make nice drawings after reading the book. Stay on topic, make it easy to understand, and keep the learning curve shallow. Write less rather than more. Be nice and encouraging to the reader. There exists another manual that provides the deep, technical details. We need to keep in mind that it will also be read by people whose native language is not English. Communication =============== Anyone who edits the book can exchange messages, files and snippets via chat with other users who are online at the same time. For discussions of wider interest, or when you hit an obstacle, please subscribe and send a message to the inkscape-docs mailing list at https://sourceforge.net/p/inkscape/mailman/inkscape-docs/ . Currently, we have 4 book admins (Elisa, Brynn, CR and me). Admins can change the book settings, add other admins and create release versions. Chapter status ============== Chapters move from one status to the next, when they're being worked on: 1. needs translation: Chapter isn't (fully) translated yet. If you speak both French and English, this is where your help is needed! This step only requires you to work on the text. You can ignore any images. 2. to be proofed: Chapter is translated, and needs to be checked by someone other than the translator, to spot errors and do some polishing. If English is your native language and you're good with words, grab this job! 3. needs images: The chapter contains images, but those are still French. Either it's just their file names that need to be changed (Workflow: download image, rename it on your computer, reupload, change link in the Chapter(s), provide meaningful alt text, delete French image) or a new screenshot is needed from the English interface. If you know how to do these things, please jump right in! (Hint: all image links follow this scheme: static/image_file.ext) 4. completed: This chapter is more or less finished. Concentrate your effort on the other ones :) If you spot a mistake or typo, improvements are still possible, of course. Important: Don't forget to update a chapter's status, after you have worked on it ;-) When you've got a great idea that would introduce a major change in the book's structure, please confer with other editors on the mailing list to see what they think about this. Cover ===== If you're good at creating meaningful art, then we need you for creating a cool cover image that shows what you can do with Inkscape and is inviting for beginners. Read more about the Cover Manager in Booktype at http://sourcefabric.booktype.pro/booktype-16-for-authors-and-publishers/_dr…. Let us know about your plans on the mailing list (see section about Communication). Styling and Customization ====================== If you know your CSS, you can help by improving the book's styling. You can read all about customization for different output formats and the front page in the design section of the Booktype manual at http://sourcefabric.booktype.pro/booktype-16-for-authors-and-publishers/for…. For the book to appear on the flossmanuals.net frontpage, the steps outlined here are required: http://write.flossmanuals.net/floss-manuals-workflow/_draft/_v/1.0/how-do-i… , section "Publish new details..."

By contributing to this book, you agree to publish your content under this license. As a contributor, please add your name to the list in the 'About this Book' chapter. This chapter will *always* be in need of new content ;-) Go! === Have fun working on the book at http://write.flossmanuals.net/start-with-inkscape/_edit/# You will find a copy of these notes in the 'Notes' tab, and you will find me working on translating French -> English there, in the late evenings (CEST). See you there, Kind Regards, Maren

How to make an *SVG* connector?
by Steve Litt 14 May '17

14 May '17

Hi all, I want to be able to make an *SVG* connector that doesn't rely on the facilities of Inkscape to do its thing. According to this URL there is such a thing: https://dev.w3.org/SVG/modules/connector/SVGConnector.html#ConnectorElement When I make a connector in Inkscape using the little connector symbol, in XML it shows up as a path, not a connector, and it has inkscape:connector-type. When I save as plain SVG, the inkscape:connector-type goes away, and it's nothing more than a line segment. How do I make a real SVG connector in Inkscape?

How to get rid of groups' transform=translate()
by Steve Litt 14 May '17

14 May '17

Hi all, So I managed to get a line segment to route itself between 2 circles. But if the 2 circles are in a group, and the group's been duped, the circles have the same cx and cy and their group has a different translate(). Ugh! I have to dup groups because I want to input onclick, onmouseover, onmouseout, and class only once on the group. Does anyone know how a group's translate() can be incorporated into its component paths' and circles' x and y or cx and cy so getting a location is as simple as reading cx and cy, rather than doing all sorts of arithmetic with the parent's translate()?

Re: [Inkscape-user] Problem with Image Sizing in Inkscape 0.92
by C R 12 May '17

It's because svg was designed as a web format and according to the wiki: "Eventually, after long arguments, the CSS working group dictated that one inch would be fixed to 96 pixels regardless of screen resolution" Yea, that's the insanity we are stuck with. Pixels being units of physical measurement. The cure is to never, ever under ANY circumstances uses pixels as a unit of measurement. It was always a bad idea, but since svg was meant to contain css it's kinds what we are stuck with if we want to be/stay compatible with web standards... even the ones that make no goram sense. :) Note: Inkscape still correctly will output your vectors at any dpi you wish, but pixels should always be calculated based on a physical measurement (metric or imperial), and pixels calculated as a dpi. This is not a problem that will go away. The CSS working group will no doubt decide to haphazardly change it again because "retina" displays are so popular, in which case it will probably be 300px / inch. It doesn't matter though. If you're using pixels to calculate witdth, you will have to expect that the width will change based on the pixel size of your output, so best thing is to not do that again in the future.

Re: [Inkscape-user] Problem with Image Sizing in Inkscape 0.92
by Maren Hachmann 12 May '17

Hi Mick, the change was necessary to be compatible with CSS standards. When you open the file with Inkscape, it will offer to scale it in that dialog where it tells you about the changed size, which intends to make the file compatible again. In your specific case, the option "Scale elements" will hopefully do what you need. Can you try that?

Problem with Image Sizing in Inkscape 0.92
by Mick Ralph 12 May '17

12 May '17

As the background to my problem, I use Inkscape to prepare drawings of sides and ends, etc, to be made into model railway carriages. The designs are then opened in the Designer Edition (DE) of Silhouette Studio for cutting out of styrene sheet on the Silhouette Portrait cutting machine. DE can open SVG files, as created with Inkscape. For Inkscape 0.48 and 0.91, this works fine and the parts are cut to the same size as the Inkscape drawing, although it is necessary to ensure that the document properties are set to "default units" of mm and "custom size" "units" of px; if custom size units are left as mm, then the actual size of a part decreases from (say) 110mm to about 88mm. I created a new default template with these properties to ensure that the Inkscape drawings would always cut at the right sizes. When Inkscape 0.92 was released I downloaded it and I have just used it to draw out another carriage. I then opened the svg file in DE and without examining it, sent it to the cutter. The parts seemed too small. I then realised that the default template was no longer in mm/px, but was now in mm/mm. When I altered the document properties back to mm/px, I opened the file in DE and examined the size of the parts. I now find that the part which should have been 110mm is now about 117mm. This is clearly useless for making scale models. I opened in v 0.92 a file which was originally created in Inkscape 0.91 and received the message that the original file was drawn at 1 inch = 90 px, but the new version uses 1 inch = 96 px. As a user rather than a developer, I do not understand the reason for this (nor do I need to understand it) - I just need to know that if I draw a line 100mm long it will cut at that length, as in the earlier versions. As I can see no option in v 0.92 to allow compatibility with earlier versions, it seems that I will have to reload v 0.91 and use that to create my drawings. Is there a compatibility option to allow drawings to be made at 90px per inch in v 0.92? Mick Ralph

moderators needed for the website
by brynn 12 May '17

12 May '17

Hi Friends, Thanks to Martin for creating the most amazing moderation system I've ever seen, for the website. Now that it's ready, volunteers are invited to join the website Moderation Team. Moderators work together to make decisions about each reported item (image, comment or member). No particular skills are needed. The biggest qualification is to care about maintaining the website as a beautiful and safe place for members to show their Inkscape work and interact. Most days you would only need to spend 15 to 20 minutes or less, although in the beginning, a little more time will probably be needed to become familiar with the system. And visit as many days as you can. The more moderators we have, the less time we each have to spend moderating. If you're interested in helping, please go to Community tab > Teams page (https://inkscape.org/en/teams/) and click on "Moderation Team". On the next page, click to request to join the team. (Sorry, I don't know exactly what the text is, for that link, but it will be regular size text, and orange color). After that, we'll contact you, and get you started. Thanks for your interest in contributing to the Inkscape Project :-) All best, brynn
