Happy Digital's JPEG Image Enhancer

Happy Digital's JPEG Image Enhancer is simply the best tool for restoring low-quality JPEG images. JPEG is a lossy format, so for any JPEG file there is a huge set of images that might have been the original. Most programs give you the middle or average image from this set. Happy Digital's JPEG Image Enhancer goes through a great deal of trouble to give you a nice looking image from this set. Clean up those blocky JPEGs.

This software is based in part on the work of the Independent JPEG Group.

How to use Happy Digital's JPEG Image Enhancer

Start up Happy Digital's JPEG Image Enhancer from the "Happy Digital" group in the Start Menu.

Registration reminder screen

If you haven't registered Happy Digital's JPEG Image Enhancer yet, a registration reminder screen like the one shown above will pop up every time the program starts. This screen reminds you how many days and how many uses are left in your trial period.

Your registration challenge code is displayed, which you copy and paste into the order form when you register the software.

A box to paste in your authorization code is provided, for when you register the software.

The "Register on Happy Digital's Website" button will bring up Happy Digital's website, with instructions on how to register the software. Registration only costs $14.95 US. That's less than a pizza!

The "Continue" button will open up the interface for the software if you still have some trial period left, or if you have entered your authorization code correctly. If your trial period has expired, and you have not entered your authorization code, it will close the program.

The interface

After the registration reminder screen, or if you have already registered, Happy Digital's JPEG Image Enhancer brings up an empty window, like the one shown above.

Like most Windows programs, you can resize the window by dragging its edges, you can move the window by dragging its title bar, and you can close the program by clicking on the "X" button at the right of the title bar.

The interface has a menu bar that you use to access all of the program's features. Many of the features also have keyboard shortcuts. The menus and shortcuts are as follows:

File menu

"Open" brings up a file requestor allowing you to choose a JPEG or BMP file to open. You can also cancel the requestor. When you open a JPEG file, the image will automatically be enhanced, but the actual file will be unchanged. The keyboard shortcut to open a file is Ctrl+O. Alternatively, you can open a file by dragging it from a folder or the desktop into Happy Digital's JPEG Image Enhancer's window.

"Close" closes the current image.

"Save As BMP" brings up a file requestor allowing you to choose a filename to save the current enhanced image as a BMP file. You can also cancel the requestor. The keyboard shortcut to save a BMP file is Ctrl+S.

"Save As JPEG" brings up a file requestor allowing you to choose a filename to save the current enhanced image as a high-quality JPEG file. You can also cancel the requestor. The keyboard shortcut to save a JPEG file is Ctrl+J.

"Next Image in Folder" will open the next JPEG or BMP in the current folder. If the current image is the last one in the folder, it will loop back to the first image. The keyboard shortcut for this action is Right Arrow (Right Cursor). For convenience, pressing the Space Bar does the same thing.

"Previous Image in Folder" will open the previous JPEG or BMP in the current folder. If the current image is the first one in the folder, it will loop to the last image. The keyboard shortcut for this action is Left Arrow (Left Cursor).

"Page Setup" opens up the Page Setup dialog so you can set up your printer settings and page margins. When printed, the image will be centered in the margins you give, and will be scaled as large as possible to fill the margins. You may choose Portrait or Landscape orientation for the image, depending on which one fits the paper better, or which orientation you want. You may also cancel the dialog if you do not wish to keep your changes.

"Print" brings up the Print dialog allowing you to print the current image. The image will be printed using the settings from the Page Setup dialog, as well as any settings you provide in the Print dialog. You may also cancel the dialog if you decide not to print. The keyboard shortcut to print is Ctrl+P.

"Exit" closes the program.

Edit menu

"Copy to Clipboard" copies the current enhanced image to the Windows clipboard. You can then paste the image into your favorite image editing application. The keyboard shortcut to copy to the clipboard is Ctrl+C.

View menu

"Zoom In" zooms into the image one step. You can zoom in more my zooming in several times. The keyboard shortcut for zooming in is the + key.

"Zoom Out" zooms the image out one step. You can zoom out more my zooming out several times. The keyboard shortcut for zooming out is the - key.

"Actual Size" zooms the image to actual size, so each pixel in the image will occupy exactly one pixel on the screen. The keyboard shortcut for zooming to actual size is Ctrl+A.

"Fit to Window" will toggle the fit to window feature. A checkmark will appear in the menu if this feature is activated. This feature scales the current image to fit into the window as best as possible, so that even if you resize the window, the image scales to fill it. Zooming in, zooming out, or zooming to actual size will deactivate this feature. The keyboard shortcut to toggle fit to window is Ctrl+F.

"Smooth Pixels" will toggle the pixel smoothing feature. A checkmark will appear in the menu if this feature is activated. This feature smooths the pixels of the image when it is scaled, so it looks better on screen. It does not affect the file itself and it does not affect printing. The keyboard shortcut to toggle pixel smoothing is Ctrl+M.

"Compare Original" will toggle between the enhanced image and the original, unenhanced image. A checkmark will appear in the menu if the unenhanced image is being displayed. You can use this feature to see just how much nicer the image looks after enhancing. The keyboard shortcut to toggle between the enhanced image and the unenhanced image is Ctrl+K.

Help menu

"On-line Documentation" opens this document on Happy Digital's website. You must have an internet connection to access this feature.

"About JPEG Image Enhancer" pops up a window with information about Happy Digital's JPEG Image Enhancer, as well as a link to Happy Digital's website, where you can get news and updates on the software.

"Register On-line" opens the registration page on Happy Digital's website, allowing you to register your copy of the software. It also opens up the registration reminder dialog, allowing you to copy and paste your registration challenge code into the on-line ordering form. You must have an internet connection to access this feature.

Context menu and batch processing

Happy Digital's JPEG Image Enhancer integrates three new commands into the Windows Shell. You can access these commands by right-clicking a JPEG file inside a folder or on the desktop. This brings up the Windows context menu, like the one shown above.

"Create Enhanced BMP" will create a BMP file with the same name as the JPEG file you select, except the filename will end in ".bmp" instead of ".jpg" or ".jpeg". For example, running this command on a file named "chestnuts.jpg" will create a new, enhanced file named "chestnuts.bmp". You can select multiple files and then right-click on one of them and select this command, allowing you to batch process files.

"Create Enhanced JPEG" will create a high-quality JPEG file with the same name as the JPEG file you select, except the filename will end in ".enhanced.jpg" instead of ".jpg" or ".jpeg". For example, running this command on a file named "chestnuts.jpg" will create a new, enhanced file named "chestnuts.enhanced.jpg". You can select multiple files and then right-click on one of them and select this command, allowing you to batch process files.

"Preview With JPEG Image Enhancer" will start up Happy Digital's JPEG Image Enhancer and open the selected file.


Limitations of the software

No international language support

Currently there is no international language support, so filenames containing international characters cannot be handled properly by the software. You can rename the file to a name with no international characters, then copy it to a folder with no international characters (like C:\TEMP\), then run the software on the file, and then rename the result to whatever you want.

Memory usage

The JPEG enhancing algorithms used in this software can consume more memory than traditional image viewers that have no enhancing capabilities. This should not cause any problems except for extremely large images.
