http://imagej.273.s1.nabble.com/how-to-call-image-calculator-in-a-plugin-tp5001766p5001771.html
> I am not a java programmer but I am using the plugins -> macro -> record approach to creating and compiling plugins. I have used this approach successfully in the past for various functions. I am having trouble calling the image calculator. I have reduced the program to just calling image calculator and multiplying two existing images together. Below is the java that is generated followed by the error. My guess is that I need to specify a type for ic when it is introduced in the code below. Can someone give me a tip to get past this hurdle? Thanks
