scriptlet:beforeDetail & afterDetail

2002-05-03 14:52

Question:

What I would like to do is in the callBeforeDetailEval() in my scriptlet to generate an image file, let the engine handle it and remove the file in callAfterDetailEval(). However this does not work since when I look inside the JRVerticlaFill code, fillColumnBand() is called after callAfterDetailEval(). By that time the file has been removed. Any reason why the order of the calls is like this:

 

jrAbstractScriptlet.callBeforeDetailEval();

jrCalculator.calculateVariables();

jrAbstractScriptlet.callAfterDetailEval();

 

this.fillColumnBand(detail, JRExpression.EVALUATION_DEFAULT);

 

Help appreciated.

Hi,

 

Why do you store your image in a file on disk

if it is generated on the fly?

 

You can supply directly a java.awt.Image object

to the image element on the report.

 

Or you can load a java.awt.Image from the file

and immediately delete the file.

You pass on this object to the image expression

and not the filename as I think you do now.

 

Good luck!

Teodor
