[Fwd: Macro to copy from clipboard]

I'm trying to write a macro to automate the counting of particles on an
SEM image. The SEM image is always in the same position, so I want the
macro to take portion of the image, copy it, then paste it as new before
working on it. I have no problem doing this manually, however when
running these lines (created by the record Macro function), I get the
selection box appearing on the original image, and a new 1024 x 674 8bit
white background that doesn't contain the image from the original
sample. Anyone have any ideas why?

Code:
makeRectangle(0, 0, 1024, 674);
run("Copy");
newImage("Sample", "8-bit Clipboard", 1024, 674, 1);

This doesn't work because the newImage() function ignores the
"Clipboard" key word. You can work around this problem by using

     makeRectangle(0, 0, 1024, 674);
     run("Copy");
     newImage("Sample", "8-bit", 1024, 674, 1);
     run("Paste");

In ImageJ 1.37b or later, you can use

     makeRectangle(0, 0, 1024, 674);
     run("Copy");
     run("Internal Clipboard");

which uses the new File>New>Internal Clipboard command.
