Are there any ways to make the macros run faster?
Macros are interpreted scripts. Some macro functions that change the pixel data (such as image operations, filtering, etc) after completed, they update the image to show the result. This update takes some time to process.
Once a macro has been written and debugged, showing the results of any intermediary steps is not critical to the results (unless the macro expects user interaction), so avoiding unecessary image updates may speed up the processing.
There is a useful macro function that sets the interpreter in batch mode. This stops the display of images between the calls, speeding up macro execution by up to 20 times:
setBatchMode(true); //batch mode on // // your code goes here... // setBatchMode(false); //exit batch mode
When the macro exits the batch mode (using setBatchMode(false); ) the macro displays the active image in a new window. Make sure that the final result is the active image (you can use either selectWindow(“your_image”); or selectImage(“your_image”); for this).
Before exiting batch mode it is not necessary to close any open images because they will be closed automatically (except the active image which is shown in a new window).
Alternatively, calling the function with the argument:
setBatchMode("exit & display");
exits batch mode and displays all images that exist (but were not shown).
