EAN13 Barcode

Version 1.0   8 May 2015

Summary

The EAN13 Barcode Widget generates images in the EAN13 barcode format.

Operation

Type the EAN13 number into the green field, then press RETURN or ENTER, or click the return button.

The number can be entered as a 12-digit code or as a 13-digit code with check digit. The Widget will not display an image (to the right) if there are fewer than 12 digits, more than 13 digits, or the 13th (check) digit is invalid.

The field below the return button displays the number with the computed (i.e. correct) check digit.

Output Formats

The Code EAN13 Text field gives the text to be used with the Code EAN13 font. This enables the barcode to be displayed in applications which support the use of the font.

The image (on the right) can be saved from the screen using the normal operating system methods. Click the green button to generate the barcode as EPS data. This can be copied to a file which should be given the .eps extension.

Options

The EAN13 Barcode Size menu button is used to set the size of the displayed image. Because of low screen resolution, the image will look best at the 100 and 200 percent sizes. The saved image will require further careful scaling to correct its size without losing resolution.

The size of the EPS image is not affected by the menu setting. It is always 1.5 by 1 inches in size, provided it is not scaled in the application which uses it. The EPS image should print well on most printers with reasonable resolution.

The Widget can draw a border around the image if desired.

Set the Use Code EAN13 Font checkbox to have the Widget use an installed EAN13 font. An EAN13 Font is supplied within the Widget package.

Installation of the ean13.ttf font requires the user to perform the installation process. On Mac OS X, opening the font file displays the usual Font Book installation dialog. Click the Install Font button.

On Windows, the user is left to perform the installation in the normal way.

The Use Code EAN13 Font checkbox affects the appearance of the Code EAN13 Text field. When the checkbox is set, the Code EAN13 Font is used to display the text in the Code EAN13 Text field. The Code EAN13 Text field can still be copied and pasted into other applications.

Cautions

Barcodes are issued by GS1 and its agencies. Please visit the GS1 website at http://www.gs1.org/ for general and legal information in relation to EAN barcodes. Creating and printing barcodes is a very tricky business because of resolution issues on computer screens and printers. If in doubt, get professional help.
