problem when passing image as java.awt.Image

2004-01-07 06:30

Hi,

. I put a Image elemente on the page header, that element shows a image that I?m passing by parameter to the report as inputStream. The error ocurr when the report shows more than one page. See it:

 

dori.jasper.engine.JRException: Error generating PDF report : client

 

nested exception:

 

java.io.IOException: java.awt.Image fetch aborted or errored

So i tried creating an java.awt.Image object from the inpuStream and the passing it the the ImageElement and have set the image Expression Class to java.awt.Image. but it throws me the following exception

 

java.lang.IllegalArgumentException: Width (-1) and height (240) cannot be <= 0

at java.awt.image.DirectColorModel.createCompatibleWritableRaster(Unknown Source)

at java.awt.image.BufferedImage.<init>(Unknown Source)

Think from the inpuStream got , is not abale to figure out the width and height of the image.

 

have anyone tried using the java.awt.Image option

of the image element and can u tell me how you have implemented it.

 

any help on this is very much appriciated..

Thanks in advance

Hi,

 

When loading java.awt.Image objects from input

streams you need to use a MediaTracker object

to make sure the image is fully loaded before using it.

 

I hope this helps.
