求助，C#，GDI+，生成图片文字不清晰

[fordawn]

bitmap = new Bitmap(width, height);
graphics = Graphics.FromImage(bitmap);
graphics.DrawString("哈喽哈喽哈喽", new Font("微软雅黑", 20),
Brushes.Black, new PointF(stringX, stringY));
graphics.Flush();
bitmap.Save(dir + i.ToString() + ".png",
System.Drawing.Imaging.ImageFormat.Png);
graphics.Dispose();
bitmap.Dispose();


为啥会出现加粗效果啊，怎么能显示出正常的字呢？

[本拉灯]

微软雅黑 就是这么粗吧。 你改用宋体就不一样了。

[失落的神庙]

你系统里有微软雅黑么？

[无涯大者]

微软雅黑必须要下载到系统字体里面，才可以显示出来！

Graphics.SmoothingMode设置下 https://msdn.microsoft.com/zh-cn/library/system.drawing.graphics.smoothingmode.aspx

Bitmap bitmap = new Bitmap(750, 35);
Graphics graphics = Graphics.FromImage(bitmap);
graphics.DrawString("哈喽哈喽哈喽", new Font("宋体", 20),
Brushes.Black, new PointF(0, 0));
graphics.Flush();
bitmap.Save("test.png",
System.Drawing.Imaging.ImageFormat.Png);
graphics.Dispose();
bitmap.Dispose();

可能你们没明白我的意思，我上个对比图你们看一下

[失落的神庙]

new Font("微软雅黑", 20, FontStyle.Regular)

[失落的神庙]

graphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.SingleBitPerPixel; 这个调整下。

[道玄希言]

Bitmap bmp = new Bitmap(300, 300); Graphics g = Graphics.FromImage(bmp); g.FillRectangle(Brushes.Aqua, new Rectangle() { X = 0, Y = 0, Height = 300, Width = 300 }); g.DrawString("哈喽哈喽哈喽", new Font("宋体", 20), Brushes.Black, new PointF() { X = 0, Y = 0 }); bmp.Save("test.png", System.Drawing.Imaging.ImageFormat.Png);

//BaseFont bfHei = BaseFont.createFont(@"c:\windows\Fonts\simsun.ttc,0", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);//中文宋体
                BaseFont bfHei = BaseFont.createFont(@"c:\windows\Fonts\SIMHEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);//黑体

bitmap = new Bitmap(width, height); graphics = Graphics.FromImage(bitmap); graphics.DrawString("哈喽哈喽哈喽", bfHei, Brushes.Black, new PointF(stringX, stringY)); graphics.Flush(); bitmap.Save(dir + i.ToString() + ".png", System.Drawing.Imaging.ImageFormat.Png); graphics.Dispose(); bitmap.Dispose();

这个有效，改成AntiAlias显示的效果会更好一些。

这样就不透明啦
