c# - 在其上绘制文本时图像质量低 (C#)

Question

我要创建位图图像并绘制文本，但用于打印目的的图像质量很低，像素可见，不像我通过 Microsoft Word 打印时那样。

出于某些原因我不想使用 PrintDocument。

抗锯齿对我也没有帮助，我已经尝试了所有图像类型(Tif、bmp、png)

以下是我们使用的部分代码。

MyBitmap = new System.Drawing.Bitmap(GetMaxWidthOfReport(), MyActualPageSizeInfo.Height);

Mygraphics =System.Drawing.Graphics.FromImage(MyBitmap);

Mygraphics.TextContrast = 4;
Mygraphics.PageUnit = System.Drawing.GraphicsUnit.Display; 
Mygraphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias; 
Mygraphics.PixelOffsetMode = System.Drawing.Drawing2D.PixelOffsetMode.HighQuality; 
Mygraphics.CompositingMode = System.Drawing.Drawing2D.CompositingMode.SourceOver; 
Mygraphics.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality; 
Mygraphics.InterpolationMode =     System.Drawing.Drawing2D.InterpolationMode.HighQualityBilinear; 

Mygraphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;

如果您有任何解决方案，请告诉我。

请尝试以下方法:

var bmp = new Bitmap(300, 100, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
using(Graphics g = Graphics.FromImage(bmp)) {
    g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias;
    System.Windows.Forms.TextRenderer.DrawText(g, 
        @"low image quality when draw text on it", Font, new Point(10, 10), Color.Black);
}
