应用于矿井LED电子显示牌的点阵式绘图软件设计

针对矿井LED电子显示牌采用矢量图技术绘图存在的图形绘制不精确、可视性差等问题,提出一种可应用于不同型号电子显示牌的点阵式绘图软件设计方案,介绍了该软件的总体设计及BMP图像的灰度化步骤。点阵式绘图软件基于组件的设计理念,实现了所见即所得的绘图功能、文字点阵转换功能、BMP图片导入/转换功能、ICO图标导入/导出功能、模拟显示功能及对外通用接口功能。比较发现,采用点阵式绘图软件绘制的原始图形及实际显示效果均明显好于采用矢量图技术绘制的图形。

Design of Dot-matrix Drawing Software Used in Mine LED Electronic Display Board

For problems of inaccurate drawing and poor visibility of mine LED electronic display board using vector technical to draw graphics,the paper proposed a design scheme of dot-matrix drawing software which can be applied in different types of electronic display boards,and introduced overall design and graying steps of BMP image of the software.The dot-matrix drawing software achieves functions of WYSIWYG drawing,text and dot-matrix conversion,BMP pictures import/conversion,ICO icons import/export,analog display and external common interface.Comparison result shows that both the original graphics and their actual display effects of the graphics drawn by the dot-matrix drawing software are significantly better than the graphics drawn by vector technical.
