01. 概述

halcon是一款非常不错的视觉类辅助设计软件，它是由非常专业的MVtec公司全新推出的最新版本。在功能上拥有非常实用方便的机器视觉开发能力，其非常独特的内部结构能够很好的辅助各种机器的视觉功能，这样不管是在医学图像上面还是各种图像分析上面都能够起到非常大的帮助，并且软件内部搭在了非常先进智能的图像算法能力，用户们在制作各种产品的时候就可以节省非常多的时间，极大的提高了工作效率。在用途方面，它也有着非常广泛的应用，能够用于多个行业的使用，就比如形态学，测量图像以及blob等等相关图像领域。作为系列的最新版本，它不光是优化了许多内容还新增了一些非常便捷的功能，现在可以做到通过更加高级方便的算法来读取条形码，极大的加快了读取速度。还对软件的开发操作环境进行非常人性化的升级优化等等

02. 开发环境

Windows系统：Windows10

Halcon版本：HDevelop 19.11

03. Halcon源码

* 读取图片文件
read_image (Image, 'fabrik')

* 获取图片大小信息
get_image_size (Image, Width, Height)

dev_open_window (0, 0, Width, Height, 'black', WindowHandle)

04. Halcon源码导出方法

4.1 选择文件–>导出

4.2 选择导出相关设置

支持导出的方式有：文本文件、C文件、C++文件、VB文件和C#文件。

05. Halcon源码导出为C++程序

5.1 导出文件选择C++

5.2 导出之后，查看导出的C++文件

///
// File generated by HDevelop for HALCON/C++ Version 19.11.0.0
// Non-ASCII strings in this file are encoded in local-8-bit encoding (cp936).
// Ensure that the interface encoding is set to locale encoding by calling
// SetHcppInterfaceStringEncodingIsUtf8(false) at the beginning of the program.
// 
// Please note that non-ASCII characters in string constants are exported
// as octal codes in order to guarantee that the strings are correctly
// created on all systems, independent on any compiler settings.
// 
// Source files with different encoding should not be mixed in one project.
