VC++制作渐变的文字，文字的色彩会越来越暗，也会越来越亮，最终形成渐变文字，帧较慢，效果并不是太好。还需要再优化完善，具体思路是先安装一个定时器，通过CDC 类的SetTextColor 函数在OnTimer()函数中改变字符串的颜色，并且注意尽量使颜色变化的梯度减校(VC++ produces gradually changed text, the color of the text will become darker and darker, and will become brighter and brighter. Eventually, it will form gradual text, and the frame will be slow. The effect is not very good. It also needs to be optimized. The idea is to install a timer first, change the color of the string in the OnTimer () function through the SetTextColor function of the CDC class, and try to reduce the gradient of the color change as much as possible.)
