Half-Tone and Quarter-Tone Images
Half-Tone images are 1-Bit bitmaps.
Quarter-tone images are 2-Bit Bitmaps.
You may convert an image to a half-tone by saving it as a 1-bit image. Use the "Advanced Save As... " feature and select a BMP or TIF format.
How to save a 1-bit Half-Tone Image:
Select a normal color image that has not been converted or edited to be half-tone.
Go into the File menu and select: Advanced Save As. A dialog
window will appear allowing you to save the image as one of 87 different
Select an image format that is a 1-bit image format, like BMP or TIF
Save the image.
Exit the Editor and load the image into PhotoELF's main viewer.
Chances are, the image will appear to be a scrambled mess. Click the 100% button on the toolbar to display the image at its true size.
This is a true half-tone.
Follow the same instructions above, except choose a 2-bit image.
Printing Half-Tones and Quarter Tones
Printing a Half-Tone only produces excellent results when the image is
printed at exactly the same height and width as the image itself.
While in PhotoELF's Print Page Layout Window, you may adjust the size of
the image. It must be the same, in inches, or it will print as a scrambled mess.
It will appear scrambled in the Print Page Layout Window, but will print correctly.
A little bit of math:
There are 96 Pixels to an inch.
You will need to calculate how big you want to print the image
before converting it to a Half-Tone or Quarter-Tone.
If you want it to be five inches wide, then you will need to resize
the original image to (5 x 96) or 480 Pixels wide.
Then convert it to a Half-Tone or Quarter-Tone
Then bring it into the Print Page Layout Window and adjust the size to
be five inches wide.
