I can't work out why this isn't saving an uncompressed PNG? Would be grateful of any suggestions!

Code: Select all

pngOpts = new PNGSaveOptions();
pngOpts.compression = 0; // 'false' also doesn't work
pngOpts.interlaced = false;

canvas.saveAs((new File(subF+'/'+basename)),pngOpts,false);
The PNG options last used (manually) seem to stick.

you must consult the javascript help - here
C: \ Program Files \ Adobe \ Adobe Photoshop CC (64 Bit) \ Scripting \ Documents
and search for "ExportOptionsSaveForWeb"!

I have this lying around on my pc:

Code: Select all

var exportOptions = new PNGSaveOptions();
//var type = ExportType.PNG24;
var fileSpec = new File(docP+"/"+docN+"__"+numbering+".png");
exportOptions.antiAliasing = true;
exportOptions.transparency = true;
exportOptions.saveAsHTML = false;
