My diagram is currently DIV that is, for the sake of the argument, 1200px wide, and 850px high.
As the diagram is extremely wide, when exporting I am getting an image that's 26,160 pixels wide.
What I really want to do is allow the user to export just what is visible on the screen. They can then pan and zoom to a specific region of the diagram and export just what they see.
I've been trying to do with via a combination of the diagram's current vertical and horizontal scroll offset (currently via diagram._verticalOffset()), and passing that into the bounds property of the export options, but it's not quite doing.
The question is: Is there an easy technique to just export the visible portion of a diagram?
--------------
Current export code for completeness:
var diagram = $("#alt-org").ejDiagram("instance");
var options = {
mode: "download",
region: "content",
//Name of the file to be downloaded
fileName: "org_chart",
pageWidth: 400,
pageHeight: 400,
bounds: {
x: diagram._horizontalOffset(),
y: diagram._verticalOffset(),
width: 1200,//width,
height: 850
},
//multiplePage: true,
//Margin to the exported file/data
margin: {
left: 30,
right: 30,
top: 30,
bottom: 30
}
};
diagram.exportDiagram(options);
