上篇中发布的程序中不支持png,jpg,gif等主流的图片格式的玩转,只支持24位位图。这一次对软件做以下更新:

  • 提供png,jpg(jpeg),tif(tiff)三种图片格式(抱歉gif尚未解决)的支持
  • 根据图片的大小适当调整字符字体大小,转换后图片视觉效果更佳
  • 优化代码

在图片格式的处理上,笔者借助codeproject上公布的CxImage工具,主要是开源。http://www.codeproject.com/Articles/1300/CxImage

关于如何在工程中使用CxImage,笔者不复述,除了上面给出作者公布的贴以外,还有以下中文版的解说贴:

测试建议:转换过程涉及灰度深浅计算,图片平均灰度偏高或者偏低转换图片效果不佳,特别是纯白或者纯黑的图片;推荐使用宠物大头照等;图片的尺寸建议越大越好,长宽700+(Pixels),越大效果越好。

源代码,包含CxImage的库文件,比较大:http://files.cnblogs.com/daoluanxiaozi/pic2_src.rar
