C# 如何在使用路径绘制文本时从右向左生成文本
我试图生成一个文本,它是RTL(从右到左的布局)。如果我用拉绳的话会很容易的。我将把字符串的所有字符保存在一个数组中,然后反向打印数组。但我用的是一个矩阵,它变换一条路径,然后画出路径。如何使用may文本绘制方法进行RTL 以下是我的代码供您参考:C# 如何在使用路径绘制文本时从右向左生成文本,c#,string,matrix,path,right-to-left,C#,String,Matrix,Path,Right To Left,我试图生成一个文本,它是RTL(从右到左的布局)。如果我用拉绳的话会很容易的。我将把字符串的所有字符保存在一个数组中,然后反向打印数组。但我用的是一个矩阵,它变换一条路径,然后画出路径。如何使用may文本绘制方法进行RTL 以下是我的代码供您参考: using (StringFormat string_format = new StringFormat()) { SizeF stringSize = e.Graphics.MeasureString(tex

TransformMatrix.Multiply(move);
rotate.RotateAt(angle, new PointF(250, 250 - Offset.Y));
TransformMatrix.Multiply(rotate);
if (flipped)
TransformMatrix.Multiply(FlipXMatrix);
TransformMatrix.Multiply(m);
path.Transform(TransformMatrix);
//Checks if the user wants the text filled or outlined
if (!isOutlined)
e.Graphics.FillPath(Brushes.Red, path);
else
e.Graphics.DrawPath(Pens.Red, path);
}
}
e.Graphics.EndContainer(gc);
}
另外,我使用布尔值来检查用户是否想要RTL
您可以使用string..()
