Decode base64 string to an image(pdf or png) using groovy

Hi,

I am able to switch the base64 string to image using Base64 class and swing builder as below:

import groovy.swing.SwingBuilder
import javax.swing.ImageIcon
import groovy.swing.SwingBuilder
import org.apache.commons.codec.binary.Base64

teststep=context.testCase.getTestStepAt(context.getCurrentStepIndex()).getLabel()
Image='$'+"{"+teststep+"#Response#//ns1:Label/ns1:Parts/ns1:Image}"
Label=context.expand(Image)
b64 = new Base64()
swing = new groovy.swing.SwingBuilder()
i1 = swing.label(icon:new ImageIcon(b64.decode(Label.getBytes())))

frame = swing.frame(title:"LABEL IMAGE", defaultCloseOperation:javax.swing.WindowConstants.DISPOSE_ON_CLOSE) {
  panel(){
    widget(i1)
  }
}
frame.pack()
frame.show()

However, I wanted the frame to be saved in local repository rather being displayed for the time being.

Secondly, I again need help for generating images if there exists more than 1 image parts in an xml response as below:

<ns1:Label>
 <ns1:Name>Label01</ns1:Parts>
 <ns1:Parts>
  <ns1:DocumentPartSequenceNumber>1</ns1:DocumentPartSequenceNumber>
  <ns1:Image>HOJBAAAElFTkSuQmCC.....</ns1:Image>
 </ns1:Parts>
</ns1:Label>
<ns1:Label>
 <ns1:Name>Label02</ns1:Parts>
 <ns1:Parts>
  <ns1:DocumentPartSequenceNumber>1</ns1:DocumentPartSequenceNumber>
  <ns1:Image>dfdJBAAAElFTkSuQmCC.....</ns1:Image>
 </ns1:Parts>
</ns1:Label>

I am working on the same. Please to-time help me with groovy script for the above two issues.
