How can an Image Data Element display a byte array picture?

Luis

Hello,
My data set contains a computed colum with an image as byte array.
I would like to know how can i do to display this into an ImageData element.
the byte array is the only thing i know from image.
At now, i use the Edit Image Item Window, select "Dynamic image" and put my data set column like dynamic expression.
It doesn't works and i have the message:
18 sept. 2008 17:40:55 org.eclipse.birt.report.engine.layout.pdf.emitter.ImageLayout getSpecifiedDimension
GRAVE: null

Can you help me?
Thanks a lot
Luis

I have found the problem.
It seems that BIRT does not accept a null value when the one use a Dynamic image.
So, to avoid this problem, i set an expression on the Visibility property in order to hide the component when value (the byte array) is Null.

see you soon
