Hi everyone :)

I have a question...

Let me explain it.

Code to draw texts:

for (int z = 0; z < base.CellNumber(); z++)
            {
                Rectangle rect = new Rectangle(((base.Hucreler[z].x / ScaleFactor -                   base.Hucreler[z].r / ScaleFactor)
                    * ZoomKontrolCarpan) / base.ZoomKontrolBolen, (base.Hucreler[z].y / ScaleFactor - base.Hucreler[z].r / ScaleFactor) *
                    ZoomKontrolCarpan / base.ZoomKontrolBolen, (2 * base.Hucreler[z].r / ScaleFactor) * ZoomKontrolCarpan / base.ZoomKontrolBolen
                    , (2 * base.Hucreler[z].r / ScaleFactor) * ZoomKontrolCarpan / base.ZoomKontrolBolen);
                g.DrawEllipse(Kalem, rect);
            }

This works great, draws cell ids.
What I want to do is to make mirror of the texts, because of I use

BitMap.RotateFlip(RotateFlipType.Rotate180FlipX)

code somewhere which takes the rotation of whole image and my texts seen like mirrored :/

Do you have any idea? Need Urgent help :/

My best Regards...

Solution 1

You have the position of the ellipse, and you have the text, which you can write with WriteString ( or DrawString, I forget ). So, where is the issue ?

Oh my, is it that easy?
I searched, but could not find that function?

I've changed the problem to another subject. I'm trying to take a mirror of the text. You have any suggestions?

Solution 2

below code shows the given text and their mirror position in picture box.
Here i'm using System.Drawing.Drawing2D.Matrix class

C#

private void pictureBox1_Paint(object sender, PaintEventArgs e)
       {

           Graphics graphics = e.Graphics;
           graphics.DrawString("Ambarish!", Font, Brushes.Black, 0, 0);

           // Transform graphics and draw string again.
           graphics.MultiplyTransform(new Matrix(1, 0, 0, -1, 0, 40));
           graphics.DrawString("Ambarish!", Font, Brushes.Black, 0, 0);

           // Reset transform 
           graphics.ResetTransform();
       }

Thank you it helped but the problem is the text I'm drawing is not in a sequence like that. They're placed according to some numbers that written in a text file. The code you send perfectly works for text in a same horizantal line. What about randomly placed ones? Because when they're placed randomly, the mirrar images placed according to their positions.

Sergey Alexandrovich Kryukov 5-Jun-11 17:25pm

It does not matter! You got a transform which does the trick, that's all you need. Everything else is just for illustration.
Also, no one can ready your mind.
This is the answer; test it and then accept.

"test it and accept"
Are you the one who is judge here that commands who will accept what? :)
I've already thanked ambarishtv, gave my 5 and ask for another thing. He may or may not give an answer, why do you bother I don't get it :/

Sergey Alexandrovich Kryukov 5-Jun-11 23:23pm

Don't be rude; nobody deny your right for your decision. You could consider my comment as a contribution to this answer. I tried to answer your "next thing". What didn't you get, anyway?

Un_NaMeD 6-Jun-11 4:22am

I wasn't mean to be rude, if it is understood like that, it's just because of my bad English, my apologies. I just thought that I had to let well enough alone with that answer.

Sergey Alexandrovich Kryukov 6-Jun-11 12:18pm

No problem. I also did not mean anything harsh to say. "Test it and than accept" should be considered as any other recommendation such as "put this option in a constructor".

The essence of this recommendation is this: the sample of the technique of graphics.MultiplyTransform/graphics.ResetTransform demonstrates that you can mirror some geometry which affects what is rendered by graphics in between, no matter what you draw. When you apply this technique you will see how to apply this to any rendered graphics or part of it (which is demonstrated in the code sample). Your further detail ("What about randomly placed ones? Because when they're placed randomly...") won't make any difference. You call your own method of rendering. This solution only shows you how to do the transform itself.
Is it clear?

it is, thank you.

Sergey Alexandrovich Kryukov 7-Jun-11 16:42pm

OK, you're welcome. I think accepting this answer is a right decision.
Good luck, call again.

I guess I misunderstood what he said.
Thank you for your comment.
