Export two images side by side on header pdf

I have been using this plugin for data table and exporting Excel and PDF files. My problem comes with PDF file export, I want to add two images on header page side by side but the only result that I got is an image in a row and the other on the next line, this is part of my code:
customize: function (doc) {
if (doc) {
doc.content.splice(0, 0, [{
margin: [0, 0, 0, 0],
alignment: 'left',
image: 'base64_Image',
width: 100,
height: 40,
},{
margin: [0, 0, 0, 0],
alignment: 'right',
image: 'base64_Image',
width: 100,
height: 40,
}]);
console.log(doc);
}
}
and this is the result:

To add an image to the header as you want, I suggest you do the following:
Add pageMargins attribute to doc
Use the header attribute of doc to add an image.
2 images side by side
customize: function (doc) {
doc.pageMargins = [40, 80, 40, 60]
doc.header = [
{
margin: 10,
columns: [
{
image: 'base64_Image',
width: 100,
height: 40,
padding: 10
},
{
image: 'base64_Image',
width: 100,
height: 40,
}
],
columnGap: 10 // optional space between columns
},
]
return doc
}
If you want an image on the left and an image on the right of the header, you just need to add adjust value of columns attribute in header. Try like this:
customize: function (doc) {
...
doc.header = [
{
...
columns: [
{
image: imageBase64,
width: 100,
height: 40,
padding: 10
},
{
width: '*',
text: ''
},
{
image: imageBase64,
width: 100,
height: 40,
}
],
},
]
}

Add a tooltip to draw container sprite

I have created a DrawContainer and I want to add a sprite with a tooltip to it, ideally with dynamic content. Unfortunately, the tooltip does not appear at all. How can the code below be corrected?
Thanks in advance.
var r = this.getSurface().add({
type: "rect", strokeStyle: "#9090f0", x: 10, y: 10, width: 40, height: 40
});
var tip = Ext.create('Ext.tip.ToolTip', {
html: "Tooltip"
});
r.on("mouseover", function() {
tip.show();
});

You could try using spriteevents plugin on the draw container, like so
var tip = Ext.create('Ext.tip.ToolTip', {
html: "Tooltip"
});
var s = Ext.create({
xtype: 'draw',
renderTo: document.body,
width: 400,
height: 400,
plugins: ['spriteevents'],
sprites: [
{
type: "rect",
strokeStyle: "#9090f0",
x: 10,
y: 10,
width: 100,
height: 100
}
],
listeners: {
spritemouseover: function (item, event) {
tip.show();
},
spritemouseout: function (item, event) {
tip.hide()
}
}
});

Change port design in JointJS

I'm trying to create graph using JointJS, where Link starts from output port od 1 element and can be connected with whole other element (or current element itself) - not only with input port.
My idea is to modify input port style, to cover element it belongs to, but I have problems to change port shape in any way, it's always a little circle on left side of element and none of my css works.
Can someone give any advice?

you can update the port attrib0utes as follows:
var a = new joint.shapes.devs.Model({
position: { x: 50, y: 50 },
size: { width: 100, height: 100 },
attrs: {
'.port-label': {
fill: 'red'
},
// change position and size of the 'a' port
'.inPorts .port0 circle': {
r: 15,
'ref-x': -20,
'ref-y': 10,
stroke: 'red',
'stroke-width': 5
},
// change color on a single port
'.inPorts .port0 .port-label': {
fill: 'blue',
}
},
inPorts: ['a', 'aa', 'aaa'],
outPorts: ['b']
https://jsfiddle.net/vtalas/43sthc6g/
However, you don't need to use ports to achieve this, you can connect to the whole element directly like this:
var a = new joint.shapes.basic.Rect({
size: { width: 100, height: 100 },
position: { x: 300, y: 300 },
attrs: {
'rect': { magnet: true }
}
}).addTo(graph);
var b = new joint.shapes.basic.Rect({
size: { width: 100, height: 100 },
position: { x: 100, y: 100 },
attrs: {
'rect': { magnet: true }
}
}).addTo(graph);
new joint.dia.Link({ source: { id: b.id }, target: { id: a.id } }).addTo(graph);
result: https://jsfiddle.net/vtalas/davLzsng/

Joint JS - How apply an event on shapes.devs

I'm new with jointjs and I try to constraint a rectangle with ports to a line.
I tried to reproduce tutorial, that works with a basic.Circle, with a basic.Rect but not with devs.Model
Could someone explian me why and how to solve this problem?
Many thanks in advance!
Here is my code :
var width=400, height=1000;
var ConstraintElementView = joint.dia.ElementView.extend({
pointermove: function(evt, x, y) {
joint.dia.ElementView.prototype.pointermove.apply(this, [evt, 100, y]);
}
});
var graph = new joint.dia.Graph;
var paper = new joint.dia.Paper({ el: $('#myholder'), width: width, height: height, gridSize: 1, model: graph, elementView: ConstraintElementView});
var m1 = new joint.shapes.devs.Model({
position: { x: 20, y: 20 },
size: { width: 90, height: 90 },
inPorts: [''],
outPorts: [''],
attrs: {
'.label': { text: 'Model', 'ref-x': .4, 'ref-y': .2 },
rect: { fill: '#2ECC71' },
'.inPorts circle': { fill: '#16A085' },
'.outPorts circle': { fill: '#E74C3C' }
}
});
var m2=m1.clone();
m2.translate(0,300);
var earth = new joint.shapes.basic.Circle({
position: { x: 100, y: 20 },
size: { width: 20, height: 20 },
attrs: { text: { text: 'earth' }, circle: { fill: '#2ECC71' } },
name: 'earth'
});
graph.addCell([m1, m2, earth]);

Why does it not work?
devs.Model is not rendered via ContraintElementView to the paper.
devs.Model uses devs.ModelView for rendering, basic.Circle and basic.Rect use ContraintElementView.
JointJS dia.Paper searches for a view defined in the same namespace as the model first. If found, it uses it. It uses one from the paper elementView option otherwise. i.e. joint.shapes.devs.ModelView found for devs.Model but no view found for basic.Circle (no joint.shapes.basic.RectView is defined)
How to make it work?
define elementView paper option as a function. In that case paper don't search the namespace and uses the result of the function first.
Note that in order to render ports devs.ModelView is still required.
i.e.
var paper = new joint.dia.Paper({
elementView: function(model) {
if (model instanceof joint.shapes.devs.Model) {
// extend the ModelView with the constraining method.
return joint.shapes.devs.ModelView.extend({
pointermove: function(evt, x, y) {
joint.dia.ElementView.prototype.pointermove.apply(this, [evt, 100, y]);
}
});
}
return ConstraintElementView;
}
});
http://jsfiddle.net/kumilingus/0bjqg4ow/
What is the recommended way to do that?
JointJS v0.9.7+
not to use custom views that restrict elements movement
use restrictTranslate paper option instead.
i.e.
var paper = new joint.dia.Paper({
restrictTranslate: function(elementView) {
// returns an area the elementView can move around.
return { x: 100, y: 0, width: 0, height: 1000 }
};
});

Putting multiple films in a circle in Raphael/Joint.js

I have an FSA in joint.js, and I need to make the states (circles) semi-filled to specific ratios, like 1/2 or 1/6, starting from the bottom of the circle. The tricky part is that it needs to be done twice - A larger semi-fill and a smaller semi-fill over it.
This is what i am trying to do:
I'm lost as to how to accomplish this.

The trick is to create three SVG circles and define clip paths for them. The following example creates a custom JointJS shape (inheriting from fsa.State) with custom SVG markup that enables the coloring that you have shown in the image:
var graph = new joint.dia.Graph;
var paper = new joint.dia.Paper({ el: $('#paper'), width: 650, height: 400, model: graph });
joint.shapes.fsa.MyState = joint.shapes.fsa.State.extend({
markup: [
'<g class="rotatable"><g class="scalable">',
'<clipPath id="clip-top1"><rect x="-30" y="0" width="60" height="30"/></clipPath>',
'<clipPath id="clip-top2"><rect x="-30" y="15" width="60" height="30"/></clipPath>',
'<circle class="a"/><circle class="b"/><circle class="c"/>',
'</g><text/></g>'
].join(''),
defaults: joint.util.deepSupplement({
type: 'fsa.MyState',
size: { width: 60, height: 60 },
attrs: {
'circle': { fill: 'white' },
'.b': { fill: 'red', 'clip-path': 'url(#clip-top1)' },
'.c': { fill: 'blue', 'clip-path': 'url(#clip-top2)' }
}
}, joint.shapes.fsa.State.prototype.defaults)
});
var mystate1 = new joint.shapes.fsa.MyState({
position: { x: 50, y: 50 },
size: { width: 100, height: 100 },
attrs: { text: { text: 'my state 1' } }
});
graph.addCell(mystate1);
var mystate2 = new joint.shapes.fsa.MyState({
position: { x: 50, y: 160 },
size: { width: 50, height: 50 }
});
graph.addCell(mystate2);
