Error loading a dicom image using ImageJ as an applet in a webpage

[charo-2]

Hi,
I have a question about ImageJ applet.
I'm trying to run ImageJ as an applet in a webpage like this example:
http://imageja.sourceforge.net/applet.html
with a dicom image rather than a jpg image, but  it doesn't work. I get
this error:

java.lang.OutOfMemoryError: Java heap space
    at ij.plugin.DicomDecoder.getString(DICOM.java:271)
    at ij.plugin.DicomDecoder.getHeaderInfo(DICOM.java:752)

How can i load a dicom image in an ImageJ applet as a web page?

Thanks very much for your help.

That means that the dicom image is larger than the applet memory settings
allow.

You can change that setting on the client computer, but you will have to
do it on _every_ computer that loads the applet individually.

Assuming that you are a Windows guy, and not really knowing what I am
talking about (just parroting what Google gave me): In Start>Control
Panel>Java, you should be able to go to the Java tab, view the "Java
Applet Runtime Settings" and add something like "-Xmx512m" to the "Java
Runtime Parameters".

In the alternative, you could look into providing a Java WebStart file,
where you have to sign the .jar but can then set the memory from there
(without requiring the user to change anything herself).

Hth,
