我使用的是图形类的束带方法绘制的图像的字符串。
I'm using the the drawstring method of Graphics class to draw a String on Image.
g.DrawString(mytext, font, brush, 0, 0);
我试图用旋转的旋转变换图形对象的功能,使文本可以在任何angle.How我能做到这一点使用旋转变换绘制由角文本。 该旋转变换code我用的是
I'm trying to rotate the text by angle using the Rotate Transform Function of the graphic object so that the text can be drawn at any angle.How can i do it using Rotate Transform. The rotate Transform Code i used is
Bitmap m = new Bitmap(pictureBox1.Image); Graphics x=Graphics.FromImage(m); x.RotateTransform(30); SolidBrush brush = new SolidBrush(Color.Red); x.DrawString("hi", font,brush,image.Width/2,image.Height/2); //image=picturebox1.image pictureBox1.Image = m;
文字是画在一个旋转的角度,但它不是画在中间,我want.Plz帮助我。
The Text is Drawn at a rotated angle but it is not drawn at the centre as i want.Plz help me out.
推荐答案这是不够的,只是 RotateTransform 或 TranslateTranform 如果要居中的文本。您需要抵消文本的起点,也通过测量:
It's not enough to just RotateTransform or TranslateTranform if you want to center the text. You need to offset the starting point of the text, too, by measuring it:
Bitmap bmp = new Bitmap(pictureBox1.Image); using (Graphics g = Graphics.FromImage(bmp)) { g.TranslateTransform(bmp.Width / 2, bmp.Height / 2); g.RotateTransform(30); SizeF textSize = g.MeasureString("hi", font); g.DrawString("hi", font, Brushes.Red, -(textSize.Width / 2), -(textSize.Height / 2)); }
