摘要
虚拟仪器的典型开发软件LabVIEW没有提供与PDF文件直接交互的接口,需要借助其他辅助工具来实现。针对这个特点,采用虚拟仪器技术和ActiveX技术进行了接口的设计。在不增加设计成本的基础上,探索了LabVIEW与PDF文件交互的方法,并结合实例详细分析和比较了利用ActiveX控件和LabVIEW软件的VI函数与PDF文件交互的两种接口技术。应用表明,该技术使得虚拟仪器能更方便地利用数字化资料,简化了LabVIEW软件的程序设计,增强了LabVIEW软件整体功能。
Typical development software LabVIEW of virtual instrument does not provide direct interactive interface to PDF document 9 thus the implementation of the interaction needs auxiliary tools. Aiming at this feature, specific interface design is implemented by adopting virtual instrument technology and ActiveX technology. Based on not to raise the design cost; the interaction methods between LabVIEW and PDF document are explored. Two interfacing technologies to PDF document, i. e. , ActiveX control and VI function of LabVIEW software, are analyzed and compared in detail by combining practical examples. The applications show that the technology makes easier for virtual instrument to use digitized data and simplifies the program design of LabVIEW software, thus enhances overall function of LabVIEW software.
