您应该对Font.Size
以下函数进行缩放变换是这样做的一个示例,但您可以对其进行改进以应用更好的结果。
这是FindFont
获取房间和具有首选大小的文本的功能,并为您提供一种字体,您可以在其中设置整个文本适合房间!
// This function checks the room size and your text and appropriate font
// for your text to fit in room
// PreferedFont is the Font that you wish to apply
// Room is your space in which your text should be in.
// LongString is the string which it's bounds is more than room bounds.
private Font FindFont(
System.Drawing.Graphics g,
string longString,
Size Room,
Font PreferedFont
) {
// you should perform some scale functions!!!
SizeF RealSize = g.MeasureString(longString, PreferedFont);
float HeightScaleRatio = Room.Height / RealSize.Height;
float WidthScaleRatio = Room.Width / RealSize.Width;
float ScaleRatio = (HeightScaleRatio < WidthScaleRatio)
? ScaleRatio = HeightScaleRatio
: ScaleRatio = WidthScaleRatio;
float ScaleFontSize = PreferedFont.Size * ScaleRatio;
return new Font(PreferedFont.FontFamily, ScaleFontSize);
}
对于您的问题,您可以将其称为以下代码:
Bitmap bitmap = new Bitmap(800, 110);
using (System.Drawing.Graphics graphics = System.Drawing.Graphics.FromImage(bitmap))
using (Font font1 = new Font("Arial", 120, FontStyle.Regular, GraphicsUnit.Pixel))
{
Rectangle rect1 = new Rectangle(0, 0, 800, 110);
StringFormat stringFormat = new StringFormat();
stringFormat.Alignment = StringAlignment.Center;
stringFormat.LineAlignment = StringAlignment.Center;
graphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;
Font goodFont = FindFont(graphics, "Billy Reallylonglastnameinstein", rect1.Size, font1);
graphics.DrawString(
"Billy Reallylonglastnameinstein",
goodFont,
Brushes.Red,
rect1,
stringFormat
);
}
