Winforms变换

Question

目前正在开发的应用程序有很多图纸。图的起源从左开始，底部代替Top，左开始。除了"DrawingString".之外，绘图工作得很完美

Graphics g;  
g.TranslateTransform(0, Height);  
g.ScaleTransform(1, -1);

//All drawings  

g.DrawString("1", new Font("Segoei UI", 9), Brushes.Green, new Point(x, y));

我得到的结果是倒过来的文本，我只想画文本普通的，其余的图纸应该总是从左下角开始吗？

编辑

    private void panel1_Paint(object sender,PaintEventArgs e)
    {
        var g = e.Graphics;
        var height = panel1.Height;
        g.TranslateTransform(0,height);
        g.ScaleTransform(1,-1);
        g.DrawRectangle(new Pen(Brushes.Black,1),new Rectangle(10,10,100,100));
        g.DrawString("Test",new Font("Segoei UI",9),Brushes.Green,new Point(10,110));
    }

我只想把课文翻过来。保持图纸的原样

Answer 1

再翻一遍。

参见下面的示例。文本Sunday显示正常。然后我们转换图形对象的矩阵并编写，这样星期一在Y轴上出现横向倒置，最后我们再一次翻转Y轴，使它恢复到原来的状态，然后编写，这通常是正常的。

​

​

private void Form1_Paint(object sender, PaintEventArgs e)
{
    var graphics = e.Graphics; // this.CreateGraphics();
    var font = new Font("Georgia", 12.0F);
    var brush = new SolidBrush(Color.Black);

    var pointF = new PointF(20F, 20F);
    graphics.DrawString("Sunday", font, brush, pointF);

    graphics.ScaleTransform(1F, -1F);
    pointF = new PointF(10F, -210F);
    graphics.DrawString("Monday", font, brush, pointF);

    graphics.ScaleTransform(1, -1);
    pointF = new PointF(200F, 200F);
    graphics.DrawString("Tuesday", font, brush, pointF);

    brush.Dispose();
    font.Dispose();
}

在代码中这样做，确保计算要显示文本的Y轴的值。

g.ScaleTransform(1,-1);
g.DrawRectangle(new Pen(Brushes.Black,1),new Rectangle(10,10,100,100));

g.ScaleTransform(1,-1);
g.DrawString("Test",new Font("Segoei UI",9),Brushes.Green,new Point(10, -110));
