drawString 出现黑边 怎么解决

[freezing2616]

如题
是用了bitmap以后出现的， 很费解！求大侠帮忙

顶你一下，哪里出现的？还是说清楚。

谢二位了 代码是画一个日历
可能关键的就是这几部分吧 反正没用bimap的时候一点问题都没有 用了以后字就有边了

在DrawString前设置文字渲染,如果不想有毛刺边缘可以任选一种:

'最高清晰度,不同显示模式或许会有些许毛刺
G.TextRenderingHint = Drawing.Text.TextRenderingHint.ClearTypeGridFit

'最基本的点阵模式,不会出现毛刺,但字形效果也差
G.TextRenderingHint = Drawing.Text.TextRenderingHint.SingleBitPerPixel
