Buried shovel warning
by Steve Litt 08 May '17

08 May '17

Hi all, If you're working with Object Properties you might be tempted to check "Lock" so the object can't receive focus on a web page. Makes perfect sense. But be aware that it also prevents the object from receiving focus in Inkscape itself, so there's no way to unlock it short of going into the XML itself and deleting the line that locks it. I did it with Gvim, you might be able to do it with Inkscape's XML view: I didn't try.

Pothole alert
by Steve Litt 07 May '17

07 May '17

Hi all, There's a pesky pothole you can fall into on the Embedded Script Files subtab of the Scripting tab of the Document Properties dialog. You click the plus sign, a script ID appears in the Script ID list, so you say "good, now I'll type in all the functions into the Content field." Bzzzt, you've just lost time, and without just the right moves it will be all the time you spent typing into that little, unenlargeable Content field. You had forgotten to highlight the script ID, and the second you do, all your functions vanish. Or, if you save and go on to other things, you lose all your functions. ALWAYS make sure you highlight the script ID BEFORE typing into the Content field. Better yet, type your functions in an editor, where you have all the room you need and all your familiar editing facilities. Then, click the plus sign, highlight the new script ID, and then copy your functions from your editor and paste them into the little Content field. If you ever notice that you've typed functions into the content field without highlighting the script ID, copy all your work out of the content field, paste it into an editor, highlight the script ID, and then copy from the editor and paste back into the content field.

Javascript inside Inkscape
by Steve Litt 06 May '17

06 May '17

Hi all, I've pretty much got it down for clickmapping with SVG elements using onmouseover, onmouseout and onclick to run Javascript from my HTML file. Now I'm trying to do the whole thing inside my SVG file, for simple stuff. For instance, I have a text/tspan element and a rectangle. When I hover the rectangle I'd like the text to change (perhaps from "init" to "hovered"). A few questions: In what program must I look at my SVG file in order to see the effects of its internal javascript? Inkscape? Chromium? Something else? When doing javascript exclusively from within my SVG file, what syntax should I use in order to change the text in a tspan? The following failed to work, doing nothing: msg = document.getElementById(tspanmsg); msg.node.textContent('shunk'); If I removed the "node." from the second line above, that didn't work either.

Be careful making a group clickable
by Steve Litt 05 May '17

05 May '17

Hi all, My clickmap has several screw heads, each being a group consisting of a circle, a path in the shape of a cross for a phillips screwdriver to go into, and an elipse that acts as a highlight. Each screw head group has an onclick event, and it fires just fine. But... In the Javascript function that receives the onclick event, evt.target is not the group, it's the individual geometry within the group that got clicked. So depending on the exact position of the mouse when clicking, it could be the circular head, the path of the cross, or the elipse highlight. Why an onclick for the group returns a target that's one of the group's items is beyond me. Here's how I dealt with it in the HTML page: function screwclick(e){ var parnt = e.target.parentElement; var circle = parnt.getElementsByTagName("circle")[0]; circle.style.fill = "gold"; } I found the parent of evt.target, then found the circle that was part of that parent, and then colored the circle. Before I figured out how to do that, sometimes the cross was turning gold, and sometimes the highlight was turning gold. Now only the circle turns gold. This could really fool a person who isn't looking for it.

Inkscape scripting
by Steve Litt 02 May '17

02 May '17

Hi all, File->Document_properties->Scripting_tab I've looked all over the web and all through my help->user manual and can't find anything about this. For one thing, I need to know how to give an embedded script a human-friendly name. I also need to know what to put in the content: Is it Javascript, and how does it differ from html based Javascript. Anyone know of any documentation on this? Theoretically, I could creat a very simple clickable map exclusively in <svg>, without the containing <html>.

How to assign a class to an object in Inkscape?
by Steve Litt 01 May '17

01 May '17

Hi all, When I do HTML, which is DOM based, I'm able to assign a class property to any element I want. In Inkscape, I've not been able to assign a class property. Does anyone know how that could be done --- it would really simplify some stuff I'm doing. If Inkscape has no provision for a class property on elements, will it at least leave as-is any class properties I put in with a text editor?

Awk SVG insertion scripts
by Steve Litt 30 Apr '17

30 Apr '17

Hi everyone, My experimentation tells me that life's much easier if I put the <svg/> element and all it contains in my HTML file, rather than trying to import it with <img/> or <object/>. So I made the following scripts to put the <svg> part of a (presumably Inkscape created) SVG file into an HTML file wherever the following is located: <div class="token">myfile.svg</div> Be sure to use doublequotes around "token": These are simple scripts. Script 1: insertsvg.awk myfile.html Script 2: justsvg.awk mysvg.svg Let's say these two Awk files were executable and on the path. In your myfile.html, place the following line (alone on its line) where you want the <svg/> element to be inserted: <div class="token">mysvg.svg</div> Now, assuming myfile.html and mysvg.svg are both in the current directory, just do the following: ./insertsvg.svg myfile.html > myfile_complete.html Now myfile_complete.html no longer has the div.token, but in its place has the entire <svg/> element from mysvg.svg. This means when you include your Inkscape built SVGs in HTML files, theres an easy automated way to do it without having to resort to cut and paste. And now for the scripts: /* ======= insertsvg.awk ==============*/ #!/usr/bin/gawk -We {printthisline = 1} /<div\s\s*class="token"\s*>\s*[^<]*\s*<\/div>/{ printthisline = 0 svgfile = \ gensub(/\s*<div\s\s*class="token"\s*>\s*([^<]*)\s*<\/div>\s*/, \ "\\1", "1") system("./justsvg.awk " svgfile) } printthisline == 1 {print} /* ======= justsvg.awk ==============*/ #!/usr/bin/gawk -We BEGIN {insvg = 0} /\s*<svg/ { insvg = 1 } insvg == 1 { print } /\s*<\/svg\s*>/ { insvg = 0; exit 0 } HTH, SteveT Steve Litt April 2017 featured book: Troubleshooting Techniques of the Successful Technologist http://www.troubleshooters.com/techniques

Path->Inset too big
by Steve Litt 30 Apr '17

30 Apr '17

Hi all, Path->Inset slightly pulls back the edges of a path. It shaves a tiny bit off the edges of the path. Path->Outset does the opposite: It moves the edges a little bit outward. Neither is a proportional grow or shrink. Anyway, I'm trying to apply Path->Inset to a bunch of objects very close to each other, just to give a little more visible separation. The trouble is, I can't find an adjustment for how much you want to inset, and even one application of Path->Inset trims off far too much from the edge. Does anyone know how to set the amount that gets taken away from the edge when you Path->Inset?

A few comments on making clickable SVG in Inkscape
by Steve Litt 29 Apr '17

29 Apr '17

Hi all, I just finished making a clickable SVG in Inkscape, embedding the <svg/> in an HTML file, and verifying that it works. Much of it is obvious, so let me start with the unobvious stuff first: If, for convenience, you use Ctrl+D to dup shapes, I think they're all clones of the first one. You need to de-clone them. But you're not done yet... Shapes in Inkscape have a tenacious habit of reverting their ID and label to Inkscape-assigned values rather than the values you assign in object->property. Make your last two steps decloning and manually setting the ID and label, and BE SURE TO CLICK THE SET BUTTON OR THEY'LL REVERT. Your events go in the area uncovered when you object->properties and then click "Interactivity". Each possible event is listed, and all you do is put in the javascript you want executed on that event. Don't wrap the Javascript in doublequotes. SIZING THE DRAWING ------------------ Be SURE that your leftmost object's leftmost portion is at X value 0. Make sure your bottommost object's bottommost portion is at Y value 0. Note that in Inkscape, at least until they change it a few versions from now, Y=0 is at the bottom of the page, not at the top. When you're done drawing, once again line up the left with X=0 and the bottom with Y=0, select everything, do the following: * File->Document_properties * Resize page to drawing or selection * Note that the height and width changed when you did the preceding. * Add double the desired image padding to both height and width. (I added 2mm to each) * Select everything on the drawing, and move slightly so it's centered within the page. * Save the document, you're done with sizing. Be aware that if the lower left of your document isn't anchored to x=0, y=0, clicking will be off or not happen.
