I am working in SVG editor 2.7 version. Here I need to change selection area for path tags in SVG using Javascript.
For example refer this image below:
Here I analysis about SVG editor, <g> tags will generated automatically and create only one selection area which is provided only rectangular shape only.
Here I need to change selection area for path section.
Below code is based on select.js :
(function() {'use strict';
if (!svgedit.select) {
svgedit.select = {};
}
var svgFactory_;
var config_;
var selectorManager_; // A Singleton
var gripRadius = svgedit.browser.isTouch() ? 5 : 4;
// Class: svgedit.select.Selector
// Private class for DOM element selection boxes
//
// Parameters:
// id - integer to internally indentify the selector
// elem - DOM element associated with this selector
svgedit.select.Selector = function(id, elem) {
// this is the selector's unique number
this.id = id;
// this holds a reference to the element for which this selector is being used
this.selectedElement = elem;
// this is a flag used internally to track whether the selector is being used or not
this.locked = true;
// this holds a reference to the <g> element that holds all visual elements of the selector

Just check both attached images, we are on the first stage (image) we to make it us the second stage - Selection area should be in over boundary as in secondary image (should be as image right side). Kindly assist me.
All suggestion will be highly appreciated.

Currently, I'm using jspdf latest version and jspdf-AutoTable 2.1.0 latest version in order to create a PDF with a very complicated table.
It works like a charm in Chrome and FireFox (big surprise!) but in IE10, it's rendering the pdf awfully (another big surprise!)
This is the output of one of the most extensive tables in pdf on chrome (Currently empty)
This is the pdf that IE10 renders
As you can see, it's not wrapping the column header as it should, nor it's expanding and showing the first columns cells and cropping the text inside them.
In order to mantain my custom table style, with it's content correct styling, I adjusted and created my own GetTableJSON method, so I can retrieve and store each individual cell style and apply it later on the createdHeaderCell and createdCell hooks

Edit:
As requested, this is the table HTML and the JSON for the tableCellStyles variable
https://jsfiddle.net/6ewqnwty/
Due to the size of the table and the amount of characters for the HTML and the JSON, I set them in a separate fiddle.
Edit 2:
I just made the fiddle runnable, being able to reproduce the issue.
https://jsfiddle.net/6ewqnwty/1/
Not perfectly as I have it in my application, I'm able to retrieve the pdf with the styling, only missing the columns headers text, but at least the issue when downloading the pdf on IE is still present
Running your example I get NaN for cellPadding. This is also probably the reason it does not work with the latest version. You could do something simple such as adding:
cell.styles.cellPadding = styles.cellPadding || 5;
in ApplyCellStyle. The reason you get NaN is that IE apparantly returns empty string instead of '0px' which chrome etc does.
Also note that you would not need to parse the html table yourself if you upgrade since cell.raw is set to the html element in the latest version. This means that you could parse the style with something like window.getComputedStyle(cell.raw).
This is not a duplicate of the other question.
I found this talking about rotation about the center using XML, tried to implement the same using vanilla JavaScript like rotate(45, 60, 60) but did not work with me.
The approach worked with me is the one in the snippet below, but found the rect not rotating exactly around its center, and it is moving little bit, the rect should start rotating upon the first click, and should stop at the second click, which is going fine with me.
Any idea, why the item is moving, and how can I fix it.

var r= new myRect(x,y,10,10,'#'+Math.round(0xffffff * Math.random()).toString(16));
svg.appendChild(r.node);
}
UPDATE
I found the issue to be calculating the center point of the rect using the self.getBoundingClientRect() there is always 4px extra in each side, which means 8px extra in the width and 8px extra in the height, as well as both x and y are shifted by 4 px, I found this talking about the same, but neither setting self.setAttribute("display", "block"); or self.style.display = "block"; worked with me.
So, now I've one of 2 options, either:
Find a solution of the extra 4px in each side (i.e. 4px shifting of both x and y, and total 8px extra in both width and height),
or calculating the mid-point using:
self.Pc = {
x: self.x.baseVal.value + self.width.baseVal.value/2,
y: self.y.baseVal.value + self.height.baseVal.value/2
};
The second option (the other way of calculating the mid-point worked fine with me, as it is rect but if other shape is used, it is not the same way, I'll look for universal way to find the mid-point whatever the object is, i.e. looking for the first option, which is solving the self.getBoundingClientRect() issue.
Here we go…

Thanks #Philipp,
Solving catching the SVG center can be done, by either of the following ways:
Using .getBoundingClientRect() and adjusting the dimentions considering 4px are extra in each side, so the resulted numbers to be adjusted as:
BoxC = self.getBoundingClientRect();
Pc = {
x: (BoxC.left - 4) + (BoxC.width - 8)/2,
y: (BoxC.top - 4) + (BoxC.height - 8)/2
};
or by:
Catching the .(x/y).baseVal.value as:
Pc = {
x: self.x.baseVal.value + self.width.baseVal.value/2,
y: self.y.baseVal.value + self.height.baseVal.value/2
};

Idea here is to have two cover flows, one horizontal and other vertical intersecting in middle. I can display one cover flow, but the other one is not getting displayed ( or is out of view). Since for one cover I can use properties from DataView , displaying the first is relatively easier than the second. I could help some suggestion on how to display the second.
I would appreciate any help with this. Thanks a lot for your time.
Data View in Ext is bound to one store. I think that much less coding would be to take two views and put them in a layout.
I solved it by super-imposing two separate views on top of each other and passing on the event from the top view to the underlying view when the drag was on a particular direction.
I'm trying to change the default orientation in a space tree but can't figure out where to add:
st.switchPosition("top", "animate", {
onComplete: function() {
alert('completed!');
}
});
So that the tree will start from the top instead of the default of right.
In the examples i've seen, the switchPosition is only used with an event handler, which i do not intend to have.
So in the example (taken from the infovis site:Infovis - spacetree ), where should i add the code (or any code) in order to change the default orientation?
var labelType, useGradients, nativeTextSupport, animate;

var ua = navigator.userAgent,

nativeCanvasSupport = (typeOfCanvas == 'object' || typeOfCanvas == 'function'),
textSupport = nativeCanvasSupport
&& (typeof document.createElement('canvas').getContext('2d').fillText == 'function');
//I'm setting this based on the fact that ExCanvas provides text support for IE
//and that as of today iPhone/iPad current text support is lame
labelType = (!nativeCanvasSupport || (textSupport && !iStuff))? 'Native' : 'HTML';
nativeTextSupport = labelType == 'Native';
useGradients = nativeCanvasSupport;
animate = !(iStuff || !nativeCanvasSupport);
})();

You can drop in orientation:'top', shortly into the new $jit.ST function, ie:
var st = new $jit.ST({
//id of viz container element
injectInto: 'infovis',
//SET THE TREE TO VERTICAL
orientation:"top",
//set duration for the animation
duration: 800,

I am using JSTreegraph plugin to draw a tree structure.
But now I need a drag, drop and attach feature wherein I can drag any node of the tree and attach to any other node and subsequently all the children of the first node will be now the grand-children of the new node (to which it is attached).
As far as I know this plugin doesnt seem to have this feature. It simply draws the structure based on the data object passed to it.
The plugin basically assigns a class Node to all the nodes(divs) of the tree and another class NodeHover to a node on hover. No id is assigned to these divs.
So I tried using JQuery Draggable just to see if any of the node can be moved by doing this
$('.Node').draggable();
$('.NodeHover').draggable();
But it doesnt seem to work. So can anyone help me with this.
How can I get drag and attach functionality?
*EDIT:: Pardon me am not so great with using Fiddle, so am sharing a sample code here for your use:*

I supose that what you need is to stablish a mechanism to modify your tree logic structure on dragging and then reload the whole tree element. This way the plugin will render your new modified structure.
This is not an easy problem and you have not outlined the exact specifications.
When you move a node, should all child nodes move with it?
What happens to a node and its child elements when a node is dropped/attached?
The plugin that you are using works well for drawing static trees, but it is not written in such a way to allow for dynamically editing the tree.
I have to agree with #Bardo in that the easiest way to make this work for your needs is to understand how the tree has been manipulated. (Thankfully the plugin seems to provide an onNodeClick option which will allow you to understand which node you are intending to manipulate). Once the tree has been manipulated then it must be completely redrawn. (There doesn't appear to be a good way to partially draw a tree).
