Javascript Html2canvas Cant Get Background

Post a Comment
Some issues using Javascript library html2canvas. The problem is that html2canvas is getting 'div2' with a transparent (sometimes white) background, I want to include the body back

Solution 1:

Logically the rendering works from the element you select.

So will not get the background, unless you select the "parent element" or "root element".

I have two solutions:

1 - Using Javascript/Jquery you can capture X and Y position from div#target then you set background-image and background-position in div#target by X/Y position

2 - You capture <body> with html2canvas, then using canvas/javascript api you crop image by X/Y position and Width/Height from div#target, see example: #242 (comment) Note: set width/height/x/y in these variables (see example):

var targetDiv = $("#target");
var sourceX = targetDiv.position().left;/*X position from div#target*/var sourceY = targetDiv.position().top;/*Y position from div#target*/var sourceWidth = targetDiv.width();/*clientWidth/offsetWidth from div#target*/var sourceHeight = targetDiv.height();/*clientHeight/offsetHeight from div#target*/

Get background-image in parent/root element:
