I have  built a very large macro and know I'm thinking about increasing his
efficiency by reducing his executing time. This macro combines series of
images and always gives a result window, I think that I could reduce the
macro executing time if I could tell the program not to show me any image
but the last one. The fact is that I don't have any idea about programming
(I built the macro using the plug in "Macro Record"), but it looks intuitive
that the PC "expends time" creating this "intermediary images" and that I
could save time if this images were not created. Am I right? , How can be
that done?

 

For example, if I had to do an XOR between the image stacks 1 and 2 and then
execute a reconstruct command using the image 1 as mask and the result of
the XOR as seed, the macro written by the Macro recorder will be this:

 

imageCalculator("XOR create stack", "1.tif","2.tif");

//run("Image Calculator...", "image1=1.tif operation=XOR image2=2.tif create
stack");

run("BinaryReconstruct ", "mask=1.tif seed=[Result of 1.tif] create white");

 

Then, I would have four stacks as a result of executing this macro: the
original ones ("1.tif" and "2.tif"), the resulting stack ("Reconstructed")
and the stack "Result of 1.tif". I'm not interested in the stack "Result of
1.tif" and I think that creating this image is a waste of time. Can I modify
the "macro code" somehow, in order to avoid creating this stack?

 

PS: if any one has any idea about how to optimize the macros running time,
please let me know, all suggestions are welcome.

 

Thank you very much in advance.
