Dynamic Image Sizing?

megabri

I'm trying to dynamically set the size of an image in a BIRT report I'm making. I query my database and if a specific field comes back true I want the image to be 4x6 if the field's value is false i want the image to be 6x4 instead. How can I dynamically set properties in BIRT?

I created a scripted dataset with alternating true/false for a resize field and then created a table. In the edit data binding expression builder I used the following script.<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>if(dataSetRow["resize"] == true) {
reportContext.setPersistentGlobalVariable("size", "true");
}else{
reportContext.setPersistentGlobalVariable("size", "false");
}
dataSetRow["resize"]</pre>
<br />
Then in the onCreate() of the image I used the following to resize<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>if(reportContext.getPersistentGlobalVariable("size") == "true") {
this.height = ".5 in";
this.width = ".5 in";
}else{
// some other height and width
}
</pre>
