Problem with saveAs in javascript

[_Jeff_Boutwell_]

Hello
I'm trying to save jpgs one by one using a for loop. This is what I have to save:

var saveFile = new File(outputFolder + "/large/" + baseNameVar + "_" + startNumVar + "_large.jpg");
var jpgSaveOptions = new JPEGSaveOptions();
jpgSaveOptions.quality = 12;
activeDocument.saveAs( saveFile, jpgSaveOptions, true, Extension.LOWERCASE);

I get this error:
General Photoshop error occurred. This functionality may not be available in this version of Photoshop.

Any ideas?
I'm using Photoshop CS3 on a Mac.

I think it may be this line:

activeDocument.saveAs( saveFile, jpgSaveOptions, true, Extension.LOWERCASE);

put a folder destination instead of the file location as the first parameter...

this is how I do:

//choose folder
var myFolder = Folder.selectDialog ();

//create new folder within chosen folder
var newFolder = new Folder(myFolder + "/newSaveFolder");
var exportFolder = new Folder(myFolder + "/newExportFolder");

newFolder.create();
exportFolder.create();

//create document
var myDoc = app.documents.add(10,10, 72, "exportOptions", undefined);

//save document in folder
myDoc.saveAs(newFolder)

similar but not exactly what u may want to do, still. Good luck.

Inspect the file that you are trying to save. It might contain characters that are not supported by the OS.

Something like LogInfo(saveFile.fsName); to see exactly what you are trying to save before you save it.

You will need to write LogInfo of course.

I had a similar problem when running a javascript snippet within AppleScript. I was trying to batch-generate compressed TIFFs from PSDs, but the compression request seemed to be ignored in pure AppleScript.

I cobbled together the javascript string as follows -
('destFile' is predetermined)

set jScript to " var saveOptions = new TiffSaveOptions();
saveOptions.transparency = true;
saveOptions.layers = false;
saveOptions.imageCompression = TIFFEncoding.TIFFLZW;
saveOptions.layerCompression = LayerCompression.ZIP;
saveOptions.embedColorProfile = true;

var nps = " & quoted form of destFile & ";
var np = new File(nps);
app.activeDocument.saveAs(np, saveOptions, false, Extension.LOWERCASE );"

By creating the file object in two steps outside of the saveAs command, it worked.

Not only that, but compression worked as it should.
