242 Vision Verification Module

Font Creation Procedure

1. Determine which characters are required to perform the verification or OCV

operation. The created font does not require that all letters and number

characters be imported into the font, just those that are to be validated.

For example, if you are going to search for a serial number such as

SN25242310, you will need to import only the capital S and N and all the

possible digits that could be found in the number.

2. Capture a sample bitmap image of the characters to be included in your font.

3. Use an image editor tool such as Microsoft Paint to create individual bitmaps

of the font characters. It is important that you size the bitmap character and

image to have the same size and spacing on all sides. It is not important what

size they start as; this can be adjusted in step 5.

4. Create a new font in FontCreator or an equivalent tool, and import the

images.

5. If using FontCreator, adjust the size and bearings of each bitmap using the

transformer toolbar.

A. Select the character using the selection tool and then open the transformer

toolbar from the menu.

B. If your bitmaps are consistently sized and spaced, you can adjust the size

while locking the aspect ratio.

C. After you have decided on a satisfactory height for your font, edit all other

characters to be the same height.

D. Adjust the bearing of each character to the same values to center the font.

6. Test the font in FontCreator Pro using the test mode.

7. Save and verify that the font can be used for OCV operations:

A. Use the procedure “Quick Stock Capture” on page 229 to capture the front

and back of the card.

B. Using the procedure “Create a Card Stock Setup with an Optical

Character Verification Element” on page 232, create a Card Stock Setup

and set the Font Filename to your custom font. Adjust other parameters as

needed if these are available in your custom font.

C. Click Test. The system will compare the OCV element on the captured

card to your custom font.
