If you are creating EPS images, the only parameter available is -m -s moves the entire QR code out of the image in this case. The program creates a slightly smaller QR code with quite a wide margin with the following command: $ qrencode -s 2 -m 10 -o qrcode.png 'Hello World!'Ī white border appears around the QR code that is exactly 20 screen pixels wide (10 QR code dots in width, with each dot two pixels). By default, Qrencode draws every black dot three by three pixels. If you are saving the QR code in PNG format, the -s parameter specifies the height of a black QR code pixel. If desirable, you can increase or decrease the edge with the -m parameter in the following example the border width would be 10 code pixels: $ qrencode -m 10 -o qrcode.png 'Hello World!' This facilitates the process of deciphering the code for programs or the smartphone later on. BARCODE MAKER V5 5 SOFTWAREIn the QR code image, the software creates a white border the width of one dot. The following command then creates a QR code containing the text “Hello World!” (Figure 1): $ qrencode -o qrcode.png 'Hello World!'įigure 2: Outputting QR codes in ASCII characters just for fun. BARCODE MAKER V5 5 INSTALLAny major distribution can install Qrencode via the package manager. The quickest way to create a QR code is with the Qrencode command-line utility. Fortunately, several QR code tools can help you avoid these problems in Linux. For example, some sites explicitly allow sharing and selling the data to third parties in their terms of use, more or less pre-programming an increase in junk mail in the future. Also, you never know for sure, what the services do with your data. For example, some services allow only QR codes in a certain size or in limited quantities. If you want to encode your address into a QR code for a business card, you could try one of the many services on the Internet. Posters, catalogs, magazines, business cards, and even television screens display the small squares, offering additional information or URLs for microsites. Thanks to numerous free reader apps for smartphones, QR codes have gained in popularity in recent years. Measuring up to 177 by 177 dots, the QR code encodes up to 4,296 characters, compared with a bar code that encodes just 13. The quick response code, or QR code, comprises a matrix of square dots instead of the usual lines. The new matrix bar code was designed to store more information than the traditional bar code and to stay legible, even if the label was dirty, wrinkled, or partially destroyed. Almost any file type could be converted to work with Barcode Maker.Read errors of unreliable, one-dimensional bar codes often caused interruptions in industrial production, prompting companies like Toyota and its subsidiary Denso Wave to develop as early as 1994 a new code for acquiring stock data. BARCODE MAKER V5 5 HOW TOIn the setup of Barcode Maker a “How to…” file is included that shows how to convert a *.XLS (MS Excel) file to a *.TXT file in the *.BK2 file format and how to load it. If you already have a list of products and want to load it into Barcode Maker you will be able to do so by converting it into the *.BK2 file format used by Barcode Maker. Barcode Maker is used by thousands of companies around the world every day and more and more companies get their copy of Barcode Maker so that they also will be able to make barcodes the easy way.īarcode Maker has a list where you will be able to add your products, so that you only have to fill in the product information once and then you will be able to just click on the product and the barcode will be made.Įach list can contain no less that 32,000 products, but you will be able to have more than one list as they can be saved individually and you will be able to merge one or more lists as long as the total number of products in the merged list isn’t more than 32,000
