Class mxImageBundle

java.lang.Object
  com.mxgraph.util.mxImageBundle

public class mxImageBundle
extends Object

Maps from keys to base64 encoded images or file locations. All values must be URLs or use the format data:image/format followed by a comma and the base64 encoded image data, eg. "data:image/gif,XYZ", where XYZ is the base64 encoded image data. To add a new image bundle to an existing graph, the following code is used: mxImageBundle bundle = new mxImageBundle(); bundle.PutImage("myImage", "data:image/gif,R0lGODlhEAAQAMIGAAAAAICAAICAgP" + "//AOzp2O3r2////////yH+FUNyZWF0ZWQgd2l0aCBUaGUgR0lNUAAh+QQBCgAHACwAAAAA" + "EAAQAAADTXi63AowynnAMDfjPUDlnAAJhmeBFxAEloliKltWmiYCQvfVr6lBPB1ggxN1hi" + "laSSASFQpIV5HJBDyHpqK2ejVRm2AAgZCdmCGO9CIBADs="); graph.addImageBundle(bundle); The image can then be referenced in any cell style using image=myImage. If you are using mxOutline, you should use the same image bundles in the graph that renders the outline. To convert a given BufferedImage to a base64 encoded String, the following code can be used: ByteArrayOutputStream bos = new ByteArrayOutputStream(); ImageIO.write(image, "png", bos); System.out.println("base64=" + mxBase64.encodeToString( bos.toByteArray(), false)); The value is decoded in mxUtils.loadImage. The keys for images are resolved and the short format above is converted to a data URI in mxGraph.postProcessCellStyle.
