I made a vector graphic in Inkscape, including layers and sub-layers for further use in Processing. I named all the layers in the UI, and realized that the final SVG only creates an inkscape:label attribute with that name, but id remains generic:
<svg:g id="layer1" inkscape:label="My custom label">
I know I can manually edit the labels in the XML editor, but is there a setting somewhere to automatically use the layer name as id?
I recently came across this question, as I was looking for the same topic. As it turned out, Inkscape (v0.92) has functions for that purpose now.
You can set IDs, and Labels in the Inkscape GUI in Object Properties menu, and they will be applied to the XML code then.
Example
Inkscape GUI
Draw a yellow rectangle and select it
Click on Object -> Object Properties...
In the menu set ID to yellow_rect and Label to #yellow_rect
Apply changes by a click on Set
To complete this example, repeat the steps above to create red_rect, set Label and ID
Eventually, group both rectanbles and set identifiers for the group as well.
XML Code
When I open the SVG file, Inkscape put my identifiers to the appropriate XML tags.
<g
id="rect_group">
<rect
rx="0.11797347"
y="250.69791"
x="5.0270834"
height="18.785416"
width="30.427082"
id="yellow_rect1"
style="fill:#f4ff00;fill-opacity:1;stroke:#000000;stroke-width:0.52916667;stroke-linejoin:round;stroke-miterlimit:3.79999995;stroke-dasharray:none;stroke-opacity:1" />
<rect
rx="0.11797347"
y="258.89999"
x="24.606249"
height="16.933332"
width="33.602081"
id="red_rect1"
style="fill:#f40000;fill-opacity:1;stroke:#000000;stroke-width:0.52916664;stroke-linejoin:round;stroke-miterlimit:3.79999995;stroke-dasharray:none;stroke-opacity:1" />
</g>
I have the same requirement when I am creating a svg for Fritzing, because fritzing doesn't refer to the inkscape:label. In such circumstance, I can make sure that label holds the legit value for id. So I make a script to do saving myself out of the dirty and heavy job.
Please note that the script ONLY READ 'Plain SVG' format.

I don't know about a setting to automatically use the layer name as id. But why not do it the other way round: if you remove the inkscape:label attribute, then the layer name automatically becomes the id of the svg:g in the inkscape UI.
The attribute inkscape:groupmode=layer is enough to make the svg:g a layer element.

I am using Inkscape to make SVG image and a little confused about the "transform-center-x" attribute like below:
<circle
style="display:inline;fill:#0000ff;fill-opacity:1;stroke:#000000;stroke-width:1.13386"
id="beacon-21737"
cx="-121.04593"
cy="42.20393"
r="1.9999999"
inkscape:transform-center-x="-0.6614634"
inkscape:transform-center-y="-10.318751"
inkscape:label="beacon"
transform="rotate(-90)">
</circle>
It seems not equal to rotate(angle, x, y). Please help me understand the meaning of the "transform-center-x/y".
This is a property of the grafical interface. If you click twice on a grafical object, you can rotate or skew it around a center indicated by a cross:
The cross can be moved by dragging it. Its position is stored in the inkscape:transform-center attribute. The value is in coordinates relative to the center of the bounding box of the grafical object. This position will also be used for other transforms, for example when you use the Object -> Transformation... dialog.
The SVG namespace transform will not reflect that center. Inkscape has an internal optimization algorithm to express rotations and other transforms, so the grafical and the standardized center might not coincide.
As always, other renderers will simply ignore tags and attributes in the inkscape namespace.
I am trying to create watermark in pdf using xslt.
I have created watermark, but the problem is that text on page is not selectable only watermark is.
How to make text selectable, and watermark to be shown in background.
How to achive it using svg. I cannot use image, because it shold be a lot of different text, so it would be hard to create so many images. Is there any way to do it.
Is there any attribute or element to make it not selectable?
<fo:instream-foreign-object z-index="-1">
<svg:svg>
<svg:g font-size="50px" >
<svg:text fill="#FF0000"
>
watermark
</svg:text>
</svg:g>
</svg:svg>
</fo:instream-foreign-object>
I'm working with an SVG file that has been output from Adobe Illustrator, so there is probably quite a bit of unnecessary code. After searching and searching I was able to come up with this.
<?xml-stylesheet type="text/css" href="SVG_css.css"?>
path:hover{
fill:#005289;
}
which gets the rollovers to work from the external stylesheet, but it of course targets every path as a rollover.
For instance, I need to target paths in a group so three elements highlight when rolled over. here is the code structure from Illustrator.
<g id="WIRE_ROOM">
<path fill="#BCBEC0" d="M357.3,24.4c0,0.6-0.6,1-1.4,1h-8.1c-0.8,0-1.4-0.5-1.4-1v-8.9c0-0.6,0.6-1,1.4-1h8.1c0.8,0,1.4,0.5,1.4,1
V24.4z"/>
<path fill="#BCBEC0" d="M357.3,51.4c0,0.6-0.6,1-1.4,1h-8.1c-0.8,0-1.4-0.5-1.4-1v-8.9c0-0.6,0.6-1,1.4-1h8.1c0.8,0,1.4,0.5,1.4,1
V51.4z"/>
<path fill="#BCBEC0" d="M376.7,24.4c0,0.6-0.6,1-1.4,1h-8.1c-0.8,0-1.4-0.5-1.4-1v-8.9c0-0.6,0.6-1,1.4-1h8.1c0.8,0,1.4,0.5,1.4,1
V24.4z"/>
</g>
I've tried associating the ID to the stylesheet, and didn't have any luck...I also tried associating a class directly into the SVG.
If I add class="locations" to the path it of course only rolls over that one element and not the group of elements. When I added the class like this nothing happened. g id="WIRE_ROOM" class="locations"
I would appreciate if someone could assist me with this, as I've searched and tried everything I know to try.
So in the case of "WIRE_ROOM" those are different pieces of equipment, and I need the hover to highlight all 3 of those areas to signify one common area. Thank you!
For future reference, the selector you're looking for is g#WIRE_ROOM:hover path or g.locations:hover path (I'd recommend using the class instead of an ID).
The hover state on the group is triggered when any of the child elements are moused-over, and then the selector applies the hover style to all the child paths.
You have to specifically mention the paths in the selector -- you can't rely on inheritance -- because your file directly sets fill colors on the paths, which takes precedence over any inherited style.
I have a SVG logo rendered to the canvas using fabric.js, the original SVG is all black in color but I need the user to be able to change the color of each different parts of the logo, resulting in a object with multiple colors, e.g.:
wikimediauruguay.org/images/5/53/Wikimedia-logo.png
How can I achieve this? If I just use object.setFill() it changes the color of the entire object but I need to change the color of every part separately to whatever colors the user choose. Thanks.
EDIT: found the solution, just posted my answer below in case somebody else has the same question.
Perhaps someone who knows something about fabric.js would answer in a way that makes more sense for your case, but with plain old svg, an object is often a <g< element with things ( like <rect>, <path>, <ellipse>) inside. Each child of the group, can have its own event handler:
<g>
<path onclick='handle(evt)' attrs=stuff />
<rect onclick='handle(evt)' attrs=stuff />
<circle onclick='handle(evt)' attrs=stuff />
</g>
The function activated by the click can then interrogate evt.target to see which of the subelements received the click, sorta like this:
if (evt.target.nodeName=="path") {evt.target.setAttribute("fill","purple")}
Solved mi problem in a very simple way: I just needed to edit the SVG on Illustrator so that every different colored part of the logo will be on a different layer, then when I loaded the SVG via fabric.loadSVGFromURL() each layer will be treated as a different object by fabric.js, then I just could edit each object (layer) separately (setFill(), etc).
I am using RaphaelJS for a project that requires vector drawing for visualization of some data.
I am not able to figure out how to push and pop transformation states.
(equivalent of context.save() and context.restore() in html5 canvas)
Can someone point me in the right direction?
thanks.
Could you explain why you need to push and pop transformation state?
In svg you don't really need to do that, the browsers do it for you. If you want a particular transform to apply to an element then just add a transform attribute to it. You can make a transform apply to many elements by using <g> elements (in Raphaël there's Paper.set, which can be used like a <g> element, and you have the Element.transform method to set the transforms).
Update:
context.save() - in svg terms this would be to take the current transformation matrix (CTM) of the element at a given time and storing it somewhere, in Raphaël I guess this might be Element.transform() (I'm not 100% sure if it includes whole stack of transformations or not, anyway, in pure svg the CTM can be fetched via the getCTM() method which is available on all elements). One way of doing this would be to insert a <g> element with the transformation you want.
context.restore() - in svg this would be equivalent to removing a transformation from the list of transforms, but note that in svg siblings don't "inherit" the transformation (this is unlike html5 canvas or OpenGL where the currently set matrix is just applied to anything you draw after setting the transform). If you want a transform to apply to many elements then you create a <g> which has the transformation that should apply to all the children of that element, and to restore you just insert elements to the parent of the <g> instead. Raphaël doesn't have any built-in support for the <g> element (unless you count Element.set, which is a similar concept), a guess for why Raphaël does this is that it's to prevent people from trying to do things like this since it becomes very easy to bloat the DOM without realizing it (remember, SVG is a retained mode graphics format, unlike canvas and OpenGL).
