How to put text inside rectangle in JsPDF

Hi I am using angular 9 and as the title said, How to put text inside rectangle in JsPDF?
pdf.rect(140, 30, 50, 25);
pdf.setTextColor(255, 0, 0);
pdf.text(143, 30, 'INVOICE')
here is the image
You should use the hooks for this
didDrawCell: data => {
let textPos = data.cell.getTextPos();
this.doc.setFillColor(255, 0, 0)
this.doc.rect(textPos.x, textPos.y, 20, 10, 'FD')
this.doc.text('test', textPos.x, textPos.y + 5)
}
the you adjust the x and y to be able to have your text in the rectangle. The above example is a working sample of what you want to achieve

Highstock/Highcharts - yAxis Label top

Using Highstock or Highcharts, I want my yAxis label on the top. What I don't want, is a varying margin between the left border of the chart and the beginning of the grid lines.
If you take a look at the following fiddle:
JSFiddle
Relevant part is:
yAxis: {
title: {
align: 'high',
offset: 0,
text: 'Rainfall (mm)',
rotation: 0,
y: -10
}
}
This is almost correct, but the offset margin is taken from the label width. If I set offset: -41 instead, it looks exactly right. The problem is, that the -41 is due to the rendered length of the text. If I change the text to something of a different length, the label is positioned wrongly again.
Is there any possibility to make sure, that the positions are always "correct" in my above definition of correct, regardless of the text length?
Screenshot, left part is wrong, right part is correct:
I think that you can use text-anchor property to style your title. Here you can find more information about text-anchor property: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/text-anchor
title: {
align: 'high',
text: 'Rainfall (mm)',
style: {
'text-anchor': 'start'
},
rotation: 0,
y: -10,
x: -25
},
I think that you need to use chart.marginLeft parameter as well. It will give you a chance to set specific left margin for your chart. Here you can find information about it.
http://api.highcharts.com/highcharts#chart.marginLeft
You may also use xAxis.labels.reserveSpace parameter to turn off reserving space for labels: http://api.highcharts.com/highcharts#xAxis.labels.reserveSpace
Here you can find live example how your chart can work with this options:

How to align text in center using jspdf

How to align text center using jsPDF.
var doc = new jsPDF();
doc.text(40, 250, 'Hi How are you');
If you are using the latest version (1.1.135) the api has changed some for the text function. It now reads as:
API.text = function(text, x, y, flags, angle, align);
If you don't need to use the flags or angle though, you can simply use:
var doc = new jsPDF();
doc.text('Hi How are you', 40, 250, 'center');
Keep in mind that the center call uses the x parameter now as the center of the text string, and not the left most border as it does when rendering left aligned.
Link to source
Edit:
Alternately you can calculate the proper x offset to just use the text function normally like so:
var text = "Hi How are you",
xOffset = (doc.internal.pageSize.width / 2) - (doc.getStringUnitWidth(text) * doc.internal.getFontSize() / 2);
doc.text(text, xOffset, 250);
Angular 6.
Footer align to horizontally center
var doc = new jsPDF();
var pageHeight = doc.internal.pageSize.height || doc.internal.pageSize.getHeight();
var pageWidth = doc.internal.pageSize.width || doc.internal.pageSize.getWidth();
// FOOTER
let str = "Your footer text";
doc.setTextColor(100);
doc.setFontSize(10);
doc.text(str, pageWidth / 2, pageHeight - 10, {align: 'center'});
doc.save("example.pdf");
Above answers didn't work for me, I ended up doing the following to center the text
let textX = (doc.internal.pageSize.getWidth() - doc.getTextWidth(text))/2
doc.text(text, textX, textY);
this worked:
var xOffset = doc.internal.pageSize.width / 2
doc.text('hello world', xOffset, 8, {align: 'center'});
2022: this works assuming your page width is 210 (default A4).
doc.text("This is centred text.", 105, 80, null, null, "center");
Here's a link to their live demo per the README:
http://raw.githack.com/MrRio/jsPDF/master/index.html
2022: I'm finding that JSPDF is buggy. It took a while to figure out how to install the advertised 'runs in a browser' implementation for a PHP app instead of a JS front end framework. There's a line that's required window.jsPDF = window.jspdf.jsPDF; that isn't mentioned anywhere in the documentation, I had to go through a downloaded example piece by piece to find it. Now I'm finding that the center text function doesn't work. In 2 different local environments and a JSFiddle, on multiple browsers, it sends the text off the left side of the page when the align:center option is implemented. While the above solution works, it breaks down if text is longer than one line, which, incidentally, is another out of the box bug - the text runs out of the document instead of wrapping, and there is no wrap option. So, it seems after all these hours I'm out of luck and I'll have to go a different route. Plugin is not maintained and this should be noted in documentation. Recommend to not waste your time.
This works somewhat, but isn't precise, if you know please tell me why.
I calculate the width of my text in order to center it myself.
For this, I used the getTextDimensions() method on my jsPDF object
var pdf = new jsPDF({
orientation : 'p',
unit: 'px',
format: [500, 750],
putOnlyUsedFonts:true
});
var textDimensions = pdf.getTextDimensions('MyText');
You can now use textDimensions.w to get text-width and textDimensions.h for height
Then use this to center your text.
var textWidth = textDimensions.w;
pdf.text('MyText', (pdfWidth / 2) - (textWidth / 2), 100);
BUT: You need to know your PDF's width to do this.
I 'solved' this by defining height and width myself, but you can easily find height and width of common formats online.
Like A4: 210mm*297mm.
Just remember to set unit: 'mm' when creating your jsPDF.
var doc = new jsPDF();
// set midPage for variable use
var midPage = doc.internal.pageSize.getWidth()/2
// Default is 210 mm so default midway by value is 105
doc.setFontSize(40);
doc.text("Octonyan loves jsPDF", 105, 15, null, null, "center");
// Better to use a variable "midPage" (from above)
doc.setFontSize(30);
doc.text("Centered (USA), Centred (UK)", midPage , 30, null, null, "center");

How to render image on Yaxis in highcharts

I want to use chart.renderer.image to put a image on Yaxis. Please see this fiddle
Is there a easy way to put the image on Yaxis? For example I want to put the image on Yaxis [0,100]. It is very difficult to using the following way to do that.
chart.renderer.image('http://highcharts.com/demo/gfx/sun.png', 0, 10, 30, 30)
.add();
In this line:
chart.renderer.image('http://highcharts.com/demo/gfx/sun.png', 20, 50, 30, 30)
.add();
first two parameters are responsible for position (x,y). So you should modify it to position object in yAxis, like in the example: http://jsfiddle.net/F4qS8/701/
