# EasyMatrixCode1 - Reading Matrix Codes (deprecated)

#### WARNING
This library is deprecated, use [**EasyMatrixCode2**](../index.html.md) instead.

<a id="easymatrixcode-why"></a>

## Why use EasyMatrixCode2 instead

Compared to `EasyMatrixCode1`, [**EasyMatrixCode2**](../index.html.md) offers the following benefits:

* Ability to read multiple data matrix codes in an image.
* Support for asynchronous processing.
* Improved consistency of reading and grading results.
* Improved consistency of processing time.
* Improved handling of deformed data matrix codes.

#### NOTE
**EasyMatrixCode2** does not support the **ANSI/AIM BC11** grading standard that was supported in **EasyMatrixCode1** as this standard is superseded by **ISO 15415** that is supported by **EasyMatrixCode2**.

## Usage

You can read the matrix code in an image by using the [`EMatrixCodeReader::Read`](../../../../doxygen_cpp/classeVision_1_1EMatrixCodeReader.html#ac5e4a3a293dfe20fbe8853ad9b8aa5e3) [<sub>.NET</sub>](../../../../doxygen_cs/classeVision_1_1EMatrixCodeReader.html#a5f80841bd1bc31da1e2a108901a4c3e1) [<sub>Python</sub>](../../../../doxygen_python/classeVision_1_1EMatrixCodeReader.html#a82bc5109d38832775681a5604ac40eb6) method.

This method returns an [`EMatrixCode`](../../../../doxygen_cpp/classeVision_1_1EMatrixCode.html) [<sub>.NET</sub>](../../../../doxygen_cs/classeVision_1_1EMatrixCode.html) [<sub>Python</sub>](../../../../doxygen_python/classeVision_1_1EMatrixCode.html) instance that contains the following information about the found data matrix code:
