摘要
研究分析了混合字体字色点阵条屏的实现难点,讨论了用Windows系统编辑Rich文本的控件的特性和方法,提出两种Rich文本位图化的方法:屏幕拷贝、图片拼接法和将所有编辑文本绘入一条足够长的图片的方法。介绍了位图点阵化的方法以及双基色LED点阵条屏的显示原理。用本文论述的方法,操作者能够任意定义点阵条屏显示文本中各个文字的字体、字色,使得点阵条屏具有丰富活泼的表现效果,从而改变当前LED点阵条屏字体、字色单一,文字表现效果不丰富的缺点。
The difficulties in realization of bar-style LED display with mixed font name and mixed font color are analyzed, characteristics of Windows Operation System used to edit Rich text control are discussed, and two methods of changing Rich text to bitmap are presented, which are screen copying,bitmaps jointing method and drawing all Rich text to a piece of long enough bitmap. The display principle of dual color bar-style LED Display is explained. Operator can define different font name and font color of every character displayed on the bar-style LED display at will by the way described in this paper, that makes display effect of bar-style LED display attractive and vivid, and enriches display effect of current bar-style LED display.
