顺序的第0帧,是将罗列文件夹函数获得的NI Vision example Image>2D Barcode文件夹下的所有二维条码子文件夹(可以打开此文件夹查看),传入到条码类型列表框的Itemnames属性,并且将值默认设置为0(第一项)。 大家可以看到,在第一帧中,图像引用没有和后面的释放缓存相连,这个东西是可以连可以不连的,因为这是一个引用...
Applications Health Industry Barcode (HIBC), used for small labels and secure data. Codablock F is a 2D bar code developed by ELMICRON, as an extension of Code 128. Within its capacities, it is possible to cut a given Code 128 into several pieces and to arrange them in a multi-row sym...
二维条码/二维码(2-DimensionalBarcode)最早发明于日本,是用某种特定的几何图形按一定规律在平面(二维方向上)分布的黑白相间的图形记录数据符号信息的;在代码编制上巧妙地利用构成计算机内部逻辑基础的“0”、“1”比特流的概念,使用若干个与二进制相对应的几何形体来表示文字数值信息,通过图象输入设备或光电扫描设备自动...
Matrix 2D barcoded open-top storage tubes come racked in 96-format in a proprietary specially designed, stackable, ANSI footprint. Latch racks save precious space in your freezer, refrigerator, compound store or on the bench top. The latch rack design enables manual multichannel pipette access to...
Enable safe, secure tracking of your precious samples with these 2D barcoded 12mL screw-top storage tubes, the perfect solution for large-volume storage.
The 2D barcode QR-Code is used for mobile tagging, automotive and logistic applications. QRCode encodes hundreds of (even Kanji) characters and is generated with TEC-IT QRCode Software.
与一维条形码一样,二维条形码也有许多不同的编码方法,或称码制。就这些码制的编码原理而言,通常可分为以下三种类型,如图2: 1. 线性堆叠式二维码 是在一维条形码编码原理的基础上,将多个一维码在纵向堆叠而产生的。典型的码制如:Code 16K、Code 49、PDF417等。
Funcode Technology helps you to conquer the 2D barcode challenges that your factory automation is facing such as reading fast-moving barcodes, reading tiny barcodes, reading low contrast barcodes and to read multiple barcodes simultaneously.
What is a 2D barcode? A 2D (two-dimensional) barcode is a graphical image that stores information horizontally as one-dimensional barcodes do, as well as vertically. As a result, the storage capacity for 2D barcodes is much higher than 1D codes. A single 2D barcode can store up to 7,...
But this 2D Barcode also has a secondary function: It allows you to include a URL for consumers. ThisQR Code solutionis dynamic, meaning you can alter or update the destination link at any time—even after it’s been created. This feature enables you to attach web content that consumers ...
