Help to save open image in Process>Batch>Macro

[sdegan]

Hi All,
I need some help on how to save the open image that results from the batch processing using the Process>Batch>Macro

I have tried the following command at the end of the macro in the 'Batch Process' window. However, this allows me to choose a directory and save only one image at a time. Every time I am prompted to choose the directory and save the image:

//the following is inserted at the end of the macro in the 'Batch Process' window
 
fullpath = getDirectory("");
N = nImages;
for (i=0; i<N; i++) {
    dir = fullpath + getTitle() +".jpg";
    saveAs("jpg", dir);
    run("Close");
}

Is there a way to have the resulted image from the batch to be saved automatically in a specified directory?

Many thanks for any help

Since your goal seems to be just changing the image file format, it
would be better to use:

    Process > Multiple Image Processor

You can set your Output image format type to Jpeg.

Using getDirectory() without arguments is equivalent of using getDirectory("Choose a Directory"),
i.e., it will trigger a prompt for user-selected directory.

Sure. Have a look at http://imagej.nih.gov/ij/developer/macro/functions.html#getDirectory

Thus, in your macro you could use:

  // to save the jpg copy next to loaded image
  fullpath = getDirectory("image");

  // to save the jpg on the User's home folder
  fullpath = getDirectory("home");

  // to save the jpg on the subdirectory "output" of the home folder
  fullpath = getDirectory("home") + output + File.separator;  

  // to save the jpg on some fixed location
  fullpath = "Path/To/Some/Fixed/Folder/;
