mxImageExport

Creates a new image export instance to be used with an export canvas. Here is an example that uses this class to create an image via a backend using <mxXmlExportCanvas>.

var xmlDoc = mxUtils.createXmlDocument();
var root = xmlDoc.createElement('output');
xmlDoc.appendChild(root);

var xmlCanvas = new mxXmlCanvas2D(root);
var imgExport = new mxImageExport();
imgExport.drawState(graph.getView().getState(graph.model.root), xmlCanvas);

var bounds = graph.getGraphBounds();
var w = Math.ceil(bounds.x + bounds.width);
var h = Math.ceil(bounds.y + bounds.height);

var xml = mxUtils.getXml(root);
new mxXmlRequest('export', 'format=png&w=' + w +
     '&h=' + h + '&bg=#F9F7ED&xml=' + encodeURIComponent(xml))
     .simulate(document, '_blank');

Functions

mxImageExport

function mxImageExport()

Constructs a new image export.

Variables

includeOverlays

mxImageExport.prototype.includeOverlays

Specifies if overlays should be included in the export. Default is false.

Functions

drawState

mxImageExport.prototype.drawState = function( state,
canvas )

Draws the given state and all its descendants to the given canvas.

visitStatesRecursive

mxImageExport.prototype.visitStatesRecursive = function( state,
canvas,
visitor )

Visits the given state and all its descendants to the given canvas recursively.

getLinkForCellState

mxImageExport.prototype.getLinkForCellState = function( state,
canvas )

Returns the link for the given cell state and canvas. This returns null.

drawCellState

mxImageExport.prototype.drawCellState = function( state,
canvas )

Draws the given state to the given canvas.

drawShape

mxImageExport.prototype.drawShape = function( state,
canvas )

Draws the shape of the given state.

drawText

mxImageExport.prototype.drawText = function( state,
canvas )

Draws the text of the given state.

drawOverlays

mxImageExport.prototype.drawOverlays = function( state,
canvas )

Draws the overlays for the given state. This is called if includeOverlays is true.
