Transforms aren't supported yet.

114 #184 #209

There's workaround - not pretty, but still (works for png and jpg pictures). Basic logic: find rotated images, replace their location and provide PHP functionality.

Step 1 : include jQuery function which provides CSS transform support.

(function ($) {
    $.fn.rotationDegrees = function () {
         var matrix = this.css("-webkit-transform") ||
    this.css("-moz-transform")    ||
    this.css("-ms-transform")     ||
    this.css("-o-transform")      ||
    this.css("transform");
    if(typeof matrix === 'string' && matrix !== 'none') {
        var values = matrix.split('(')[1].split(')')[0].split(',');
        var a = values[0];
        var b = values[1];
        var angle = Math.round(Math.atan2(b, a) * (180/Math.PI));
    } else { var angle = 0; }
    return angle < 0 ? angle+360 : angle;
   };
}(jQuery));

Step 2 : replace location of rotated images with PHP URL (include this before html2canvas render).

$("img").each(function(){
    rot = $(this).rotationDegrees();
    if (rot != 0)
        $(this).attr("src", "/rotateimg.php?rotate=" + rot + "&loc=" + $(this).attr("src"));
});

Step 3 : create rotateimg.php which provides rotate functionality

<?php
$loc = $_GET['loc'];
$rot = -$_GET['rotate'];
$path = "/web/images/path"; // $_SERVER['DOCUMENT_ROOT'] ?
$source = NULL;

if (substr($loc, -3) == "png")
    $source = imagecreatefrompng($path . $loc);
else if (substr($loc, -3) == "jpg") {
    $source = imagecreatefromjpeg($path . $loc);
}

imagealphablending($source, false);
imagesavealpha($source, true);

$img = imagerotate($source, $rot, imageColorAllocateAlpha($source, 0, 0, 0, 127));
imagealphablending($img, false);
imagesavealpha($img, true);

imagepng($img);

?>

I hope it helps. =)

I've added support for images rotated by 90, 180 or 270 degrees. https://github.com/mjaggard/html2canvas/tree/simple-rotation

Non-image rotation is not generally supported and nor are other transformations (although I some translations and rotations are supported by html2canvas anyway because it lets the browser do the work).

Subscribing. Looking for a better rotation solution for images/html here as well. We need -webkit-transform to work with "degrees", not this matrix stuff though.

Thanks

Greetings,

What about scaling? I have a scaled text that doesn't renders properly; the characters get all cramped together. Can anyone point me to the right direction for maybe implementing this scaling feature?

I need rotate :(

The implementation of transform scale would be great. I think it is a really important point, because you are able to increase font- and image-quality. If you render for a example a text and zoom with the browser, the quality is really bad. That could make your html2canvas-plugin also useful for text-editors and so on.

@niklasvh : Do you plan to implement this feature in near future? I would appreciate that and would give u a donate for that.

Hi, this feature really miss this excellent tool, any plan to this feature ?

@mjaggard - is there any chance your image rotation code can be integrated in the recent version of the library?
I've looked at your code and it seems to have very different structure.
Thanks!

Hi,

Do you plan to add this feature soon ?
It would be very useful !!

Thanks a lot !

Hi,
The rotation is already(webkit-transform) working in this version for
example.
Add this class in any div and check i already tested it.

.rt{-ms-transform: rotate(7deg); /* IE 9 _/
-webkit-transform: rotate(7deg); /_ Chrome, Safari, Opera */
transform: rotate(7deg);}

@liteelips me too, i also need text rotation :(

Does anyone find any solution for rotated divs screenshot?

Full working code with rotation and transform for all browser. Can't attach the file. Mail me to collect the file [email protected]

Awesome, thank you!

Have you considered making a pull request or putting on JS Fiddle?

hi ,
that great !! can i get the file please as the rotation and transformation
is working for you now.

Hi, I am also struggling to get transforms (rotate) to work, specifically in IE. The finished canvas does in fact contain a rotated element, but typically only half of the element is shown.

This is the style of the script:

$('#<id of element>').htmlToCanvas({
        width: 1000, // dimension of your html page
        height: 600, // dimension of your html page
        complete: function(){
      var image = this.htmlToCanvas.toBinrary(); // will return base64 image data
      $('<img emelent>').attr("src",image); // use this as a src of any img element
   }
  });

// Html to Canvas and saving image to backend

htmlToCanvas.js file

(function($){

var canvasCounter = 0;
var canvas, cnvs, ctx, elementArr, callback, _this;

$.fn.htmlToCanvas = function(options){

    var defaults    = {width: 1000, height: 600, complete: null};
    callback        = $.extend(defaults, options);
    _this           = this;

    return this.each(function(){

        createImage('#'+$(this)[0].id);
    });
}

$.fn.htmlToCanvas.toBinrary = function() {
    return cnvs.toDataURL("image/jpeg",1);
// return   cnvs.toDataURL({
//      format: 'png',
//      left: 0,
//      top: 0,
//      width: 200,
//      height: 150
//  })
}

$.fn.htmlToCanvas.removeCanvas = function() {
    canvas.remove();
}

function createImage(divobj)
{
    ////console.log(divobj);

    if(canvas) canvas.remove();
    canvas = $('<canvas id="canvas" width="' + callback.width + '" height="'+ callback.height +'" style="display: block;"></canvas>');
    $('body').append(canvas);
    cnvs    = document.getElementById('canvas')
    ctx     = cnvs.getContext("2d");

    ctx.fillStyle = $(divobj).css('background-color');
    ctx.fillRect(0,0,callback.width, callback.height);
    canvasCounter = 0;
    elementArr      = [];

    $(divobj + " img").each(function(index){
        elementArr.push({type: 'img', zindex: $(this).css('z-index'), imgobj: $(this)});
        console.log($(this));

        elementArr.push({type: 'txt', zindex: $(this).css('z-index'), imgobj: $(this)});

         //var a_zindex = a && a.zindex || "",
            //b_zindex = b && b.zindex || "";
        //return a_zindex.localeCompare(b_zindex);
        var dif = Number(a.zindex - b.zindex);
        //alert('cal '+dif);

@arindamm @niklasvh : hello sir , overflow :hidden and margin-left: -42px; is not getting applied to my images . Kindly refer me a solution or Can you please update the file . Please.

I didn't work in that part. Sorry to say I can't help. you can make your
own function and crop the image by canvas.draw() function.

you can do a workaround which is told here:
http://www.jjoe64.com/2015/10/html2canvas-and-css-transform-rotate.html

@jjoe64 https://github.com/niklasvh/html2canvas/issues/209#issuecomment-152904727

Guessing this still hasn't been looked at.

Kind of needed translateY to work for vertical aligning (would have hoped this would have been a simple implementation but obviously not).

👍

          img = document.createElement("img")
          img.src = canvas.toDataURL()
          newCanvas = document.createElement('canvas')
          ctx = newCanvas.getContext("2d")
          newCanvas.height = 350
          newCanvas.width = 200
          ctx.translate(185, 35)
          ctx.rotate(90 * Math.PI/180)
          ctx.drawImage(img,0,0); #draw it
          canvasURL = newCanvas.toDataURL()

From html2canvas, I get canvas. I then use the above javascript to create a newCanvas which is rotated 90 degrees.

use height, width, translate property according to your use case

The box-shadow css3 is not working ？ But still thank you

Transforms are partially supported in 1.0.0

@niklasvh Any info on exactly which transforms are and are not supported?

rotate seems not working
