What a great script. I extended it to recurse through subdirectories, and to filter out images that are too small to be reasonable crops. I hope this helps someone else as much as the original helped me.
#target Photoshop
// This script recurses through a directory structure and saves straightened/cropped images to
// a "StraightenedAndCropped" subfolder.
// The function that does this tends to produce a lot of junk, so
// this script also filters out images that aren't large enough to
// be likely candidates.
// optional (for debugging)
//$.level = 2
//$.bp()
app.bringToFront;
// you can use a folder selection dialog
var inFolder = Folder.selectDialog("Please select top-level folder to process");
// or you can hard-code the folder if you like (making sure to escape the path in Windows)
//var inFolder = new Folder("C:\\some\\folder");
if(inFolder != null){
ProcessFolder(inFolder);
};
function ProcessFolder(folder) {
// process any files here first
var fileList = folder.getFiles(/\.(jpg|tif|psd|)$/i);
if (fileList.length > 0) {
// only create a subfolder etc. if we found anything
var outfolder = new Folder(decodeURI(folder) + "/StraightenedAndCropped");
// not sure whether the exists property refreshes on-demand so save an indicator of whether we created the folder
var created = false;
//if (outfolder.exists == false) outfolder.create();
for(var a = 0 ;a < fileList.length; a++){
if(fileList[a] instanceof File){
var doc= open(fileList[a]);
doc.flatten();
var docname = fileList[a].name.slice(0,-4);
CropStraighten();
var originalWidth = doc.width;
var originalHeight = doc.height;
doc.close(SaveOptions.DONOTSAVECHANGES);
var count = 1;
while(app.documents.length){
// if the width and height of the derived image are not both at least 85% of both of the original dimensions,
// do not save it at all
if (activeDocument.width.value >= (originalWidth.value * .85)
&& activeDocument.height.value >= (originalHeight.value * .85)) {
// create the output folder on demand
if ((outfolder.exists == false) && !created) {
outfolder.create();
created = true;
}
var saveFile = new File(decodeURI(outfolder) + "/" + docname +"#"+ zeroPad(count,3) + ".jpg");
SaveJPEG(saveFile, 12);
count++;
}
activeDocument.close(SaveOptions.DONOTSAVECHANGES) ;
}
}
}
}
// now go looking for new folders, and recurse into them (just don't recurse into our own folders)
var fileAndFolderList = folder.getFiles();
for (var i = 0; i < fileAndFolderList.length; i++){
if (fileAndFolderList[i] instanceof Folder && !endsWith(decodeURI(fileAndFolderList[i]), "StraightenedAndCropped")) {
ProcessFolder(fileAndFolderList[i]);
}
}
