Aztec Encoder SDK ActiveX description
Create Aztec barcode symbols from alpha/numerical text/binary.

Aztec Code is a high density 2 dimensional matrix style bar code symbology that can encode up to 3832 numeric or 3067 alphabetic characters or 1914 bytes of data. The symbol is built on a square grid with a bulls-eye pattern at its center. Data is encoded in a series of "layers" that circle around the bullseye pattern.

Each additional layer completely surrounds the previous layer thus causing the symbol to grow in size as more data is encoded yet the symbol remains square. Aztec's primary features include: a wide range of sizes allowing both small and large messages to be encoded, orientation independent scanning and a user selectable error correction mechanism.

The SDK includes API [static library and dynamic library], ActiveX and ASP Compnent. Using the SDK, you can
· Create Aztec barcode symbols from alpha/numerical text/binary.
· Output barcode image with the formats such as BMP, GIF, JPEG, PNG.
· Render barcode images on any devices, and create device resolution dependent images.
· Full controls of the bar code image styles, such as background color, bar color, image quality, rotation angle, x-dimension, captions, etc.
· Use selectable error correction, from 5% to 95% of data region.
· Support structured Append mode.
· Support Tilde mode
· Support 36 error correction levels

ActiveX is the name Microsoft has given to a set of "strategic" object-oriented programming technologies and tools. The main technology is the Component Object Model (COM). Used in a network with a directory and additional support, COM becomes the Distributed Component Object Model (DCOM).

The main thing that you create when writing a program to run in the ActiveX environment is a component, a self-sufficient program that can be run anywhere in your ActiveX network (currently a network consisting of Windows and Macintosh systems). This component is known as an ActiveX control. ActiveX is Microsoft's answer to the Java technology from Sun Microsystems. An ActiveX control is roughly equivalent to a Java applet.

One of the main advantages of a component is that it can be re-used by many applications (referred to as component containers). A COM component object (ActiveX control) can be created using one of several languages or development tools, including C++ and Visual Basic, or PowerBuilder, or with scripting tools such as VBScript.

With Aztec Encoder SDK ActiveX library you can develop application or using it in ActiveX container application such as Internet Explorer, Microsoft Office and etc.. Using Microsoft Visual C++, Microsoft Visual Basic,Microsoft Visual J++, Borland C++ Builder ,Borland Delphi, Borland J++ Builderor other development tools support to use COM.

Limitations:

· With 2D barcode encoder and decoder SDK, some of the input element will be replaced with char '*' before encoding, and some of the output element will be replaced with '*' after decoding.
· With 1D linear barcode encoder and decoder, some of the input element will be replaced with char '0' before encoding, and some of the output element will be replaced with '0' after decoding.
· The Trial version have 30 days' evaluation time, you must remove it from your computer and your application after expiration.
