I am writing a plug in  (not a Macro) that uses IJ.run to open raw images.  It works for fixed numeric parameters, but fails when I try to use variables for the parameters.

This works:
_______
IJ.run("Raw...", "open=temp.raw image=8-bit width=128 height=128 offset=0 number=1 gap=0 white");
_______

This does not work
_______
int a2=128;
IJ.run("Raw...", "open=temp.raw image=8-bit width=a2 height=a2 offset=0 number=1 gap=0 white");
________

The error message is
Numeric value expected in run() function  
Dialog box title: "Import>Raw..."
Key:"width:"
Value or variable name: "a2"

Please advise as to how I might be able to open a raw image with a variable for the width and height

thanks in advance
