its saving both text and lines now, but a small part image is getting cropped at the bottom when i open the saved image. Why??

I can save only image with lines if i use my method and image with text at the bottom of the image if i use your method. How do i save both lines and text??

SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "JPEG Files(*.jpg)|*.jpg";
Bitmap orgImg = new Bitmap(resized.Width, resized.Height);
pictureBox1.DrawToBitmap(orgImg, pictureBox1.Bounds);
if (sfd.ShowDialog() == DialogResult.OK)
orgImg.Save(sfd.FileName);

Am saving this way, as am drawing lines on the image using pictureBox_paint.

am not able to save those contents :(

Thank you :) working!!

am stretching the image like this..
Image source = Image.FromFile(openFileDialog1.FileName);
Image resized = new Bitmap(source, pictureBox1.Size);

pictureBox1.Image = resized;
then also its not working

I need to stretch the image to fit the pictureBox size while loading. I tired with your code, not able add text at the bottom of the image :(

I want the info to be stored at the bottom of the image. Just like a status bar.

Am getting information from first form and display those info in the second form where i load the image. So there is no way to save image along with statusstrip contents??

how do i update the range in foreach loop??

Thanks... its working fine now :)

pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;

Am stretching the image to the pictureBox size.

still not working... :( someone plz guide me

yes am streching the imageto fit the pictureBox size...

still my circles are drawn much away from the clicked point :(

I have already tried with the character. But could get the exact output. Please guide me in the other way i.e., draw circle and 2 lines with swapped co ordinates.

Sometimes I need to draw Cross i.e., X also. So in general, i change the 'str' value according to the requirement.

Am trying to draw a small circle on the image with a mouse click. But the circle is drawn away from the mouse clicked point. here is my code.
private void pictureBox1_MouseClick(object sender, MouseEventArgs e1)
{
string str = "O";
if ((e1.Button & MouseButtons.Left) == MouseButtons.Left)
{
Bitmap b = (Bitmap)pictureBox1.Image;
pictureBox1.Image = b;
Graphics g = Graphics.FromImage(b);
p = new Point(e1.X, e1.Y);
Pen p3 = new Pen(Color.Red, 1);
this.Text = p.ToString();
SizeF sizef = g.MeasureString(str, Font);
f = new Font(new FontFamily("Times New Roman"), 10);
g.DrawString(str, f, Brushes.Red, ((p.X)), ((p.Y)));
}
pictureBox1.Invalidate();
}

its working perfectly... thanks :)

am getting array out of bounds expection at lines
xLines[selectedLineIndex] = e.X;
yLines[selectedLineIndex] = e.Y;

Its working fine if i have only vertical lines. I included horizontal lines also in the same manner. But when i drag any line, both horizontal and vertical lines are moved.

Thanks a ton :)

One last question, When i do pictureBox1.Image = null; for clearing the pictureBox...only image is getting cleared, Not the lines :(

Thank you so much. It works perfectly :) Sorry for my mistakes. Thanks again

How to use the extended pictureBox in my code? Sorry am new to C#

Attaching my code...am Still not able to drag.

am not able to drag lines :(

To be more specific user should be able to drag lines on the image and save.

Yes. I need manual selection of lines. User should be able to select lines just by a mouse click on that particular line. Please help. And thank you so much

Am getting error at this line --> int dist = Math.Abs(e.X - xLines[k].X);

Error 1 'int' does not contain a definition for 'X' and no extension method 'X' accepting a first argument of type 'int' could be found (are you missing a using directive or an assembly reference?)

yes am trying to save the image with grids and these grids are dragable. To be more specific, its like a horizontal and vertical ruler on the image.

am able to save only the image, not the grids. I feel it is refreshing every time i move the grid. I have attached the code. U can hav a look at it.
