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:
Alt is an optional boolean (default is false) that specifies if the value or the fallback should be returned in <getImage>.
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.
The keys for images are resolved in <a href="Graph.html#postProcessCellStyle" class="tsd-kind-property">Graph#postProcessCellStyle</a> and turned into a data URI if the returned value has a short data URI format as specified above.
A typical value for the fallback is a HTML link as defined in RFC 2557. Note that this format requires a file to be dynamically created on the server-side, or the page that contains the graph to be modified to contain the resources, this can be done by adding a comment that contains the resource in the HEAD section of the page after the title tag.
This type of fallback mechanism should be used in IE6 and IE7. IE8 does support data URIs, but the maximum size is limited to 32 KB, which means
Specifies if the fallback representation should be returned.
images
images:ImageMap
Maps from keys to images.
Methods
getImage
getImage(key): null | string
Returns the value for the given key. This returns the value
or fallback, depending on . The fallback is returned if
is true, the value is returned otherwise.
Parameters
key: string
Returns null | string
putImage
putImage(key, value, fallback): void
Adds the specified entry to the map. The entry is an object with a value and
fallback property as specified in the arguments.
