Okay, my script is working now as I want it, I tested it on a set of 13 files, and set the stacknumber to 4. It stacks 3 groups of 4 images, ignores the last image, and saves 3 tiff files, then loops and stacks the remaining 3 tiff files together, saves a file, then saves a duplicate labelled FINAL_STACK to show which one it is. Work in progress, but I hope to automatically calculate the ideal stack number given a maximum stack number based on the number of images to minimise unused images.
var folder = new Folder('D:/RAW Compare/teststack');
var flist1 = folder.getFiles('*.tif');
//flist1.length = number of items
var stackDepth = 0;
var totalStackCount = 0;
var stackNumber = 4; //how many images to stack at once, you should make sure your files are evenly divisible by this
var recurseDepth = 0;
cTID = function(s) { return cTID[s] || (cTID[s] = app.charIDToTypeID(s)); };
sTID = function(s) { return app.stringIDToTypeID(s); };
const deleteRecursives = true; //delete recursive stacked images once they are finished
function runLoadStack(fileList) {
var loadLayersFromScript = true;
// @include 'Load Files into Stack.jsx'
//var fList = folder.getFiles('*.tif')
var aFlag = true;
//alert(fileList.length + " " + typeof(fileList));
loadLayers.intoStack(fileList, aFlag);
loadLayers.alignStack = function( stackDoc ){
selectAllLayers(stackDoc, 0);
}
}
function selectAllLayers2() {
var ref = new ActionReference();
ref.putEnumerated(cTID('Lyr '), cTID('Ordn'), cTID('Trgt'));
