Well, you've installed Enlarger PRO already, that's a good start, award yourself a gold star - we'll go straight on to how to use the program.

Start up the main Enlarger PRO application, you can see three main areas on the dialog: Input, output and the preview pane.

1)Simple Operation

In order to Enlarge a photo we need to do the following:

  • First we need to add some files to enlarge, there are a couple of ways to do this. The main way is to simply click the "Add Files" button beneath the list of input files - or select the "Add" option from the "File" menu, this will pop open a window allowing you to browse around and select as many images as you want to enlarge. The second method is to simply drag the images from Windows Explorer and drop them anywhere on the Enlarger PRO window. Supported file types include Windows Bitmap files, JPEGs, GIFs, TIFFs and PNG files.
  • You can view any of the images by double-clicking on them in the input files window, remove selected files with the "Remove" button or clear all of the files in the list using the "Clear" button. Also if you hover over any file in this window, a little tip pops up telling you more about the image - including the size at which it will be printable enlarged - you can change to your preferred printing resolution using the "Target D.P.I." menu option on the "Options" menu.
  • In the output section of the dialog, we need to select a directory in which Enlarger PRO should create the enlarged versions of your images. To do this, either type the name of the directory, or press the "..." button next to the text input to browse to the required directory.
  • While we're in the vicinity, we can set up the enlargement factor - this factor applies to all of the files we're enlarging.
  • We're now ready to start enlarging, click the "Process" button and watch as Enlarger PRO scampers off like an eager puppy to enlarge your images. Every now and then it'll give you a little glimpse of how it's doing - unless you turn off the preview image using the option in the "Options" menu. We'd recommend turning off the preview on larger enlargements - it does use up memory and CPU time
  • That's basically it, when the dialog buttons become available again, all of your files have been processed.

2)Advanced operation

  • Image quality can be further improved by selecting a larger scaling factor and then, using a regular image manipulation program, e.g. Adobe Photoshop, down-sampling the resultant image to the required size. It is worth noting that when printed out, most images look more like a 50% zoomed version of the image on screen.
  • Hand drawn/vector images can be anti-aliased using Enlarger PRO in order to smooth jagged edges, simply scale the image by a factor of 2 or 4, then down-sample the output image to the original size.
  • Enlarger PRO has been written to be multi-threaded and, as such, will perform better on Dual CPU/Hyper threaded PCs.
