C# Snippet Tutorial - How to Draw Text on an Image

Hello there ! Reaaly great code you wrote here... I was wondering how you could get a Rectangle Buffer of the image. Imagine you want to do some animation let's say a vertical scrolling, well you would have to Redraw the rectangle you just took in buffer before you draw the text and then move the location of the text...

A nicely written code and simpler explaination.

Really a good work.

Thanks, Abdullah

Sample doesn't work!!! No text appearing on image!!!

i want to read text from an image file. How do i do that

Excellent code! Exactly what I needed!

That was great. Thanks

Nice code. Very clean and simple.

Great article. Any idea how you would add drop shadow to the text?

Thanks!

simple, structured, nice documented.

hopefully we could share more code snippet, since my site also dedicated for programming and information technology issue.

nice to meet you,

Nice code. Easy to use and works well. I've a ?? though. If you wanted to use differents fonts, would they have to be on your server, or the client machine?

I have a Panel control on which I am performing:

xGrfc.DrawString(myStr, xFont, xBrush, 5, 5);

The first time this is proc'd there is no problems. When an event occurs, however, and the DrawString is proc'd, I receive and invalid parameter error. What do I need to do to get the DrawString to function. Essentially, I am wanting to redraw a new string.

Thanks in advance... David

was having a problem how to make the font work but now its working, thanks

Hi, Nice tutorial

I've tried your code and the only problem I have with it is that once I've saved the image with the added text, its size grows from 2 Mb to 9 Mb ! Is there any way to keep the original image settings ? Thanks

You are right I was not saving it properly. Now it's better but it still a few kilobytes bigger than the original. If it's the original is serveral Mbytes big, it's not a huge issue, however if the original is, say 65 Kb, it ends up being 175 Kb, and that's an issue to me.

This is my code, is there anything wrong with this ? :

 public void AddWatermark(string pPath, string pWatermark){
      Image image = Image.FromFile(pPath);      
      Bitmap bmp = new Bitmap(image);
      bmp.SetResolution(image.HorizontalResolution, image.VerticalResolution);

      ImageCodecInfo iciJpegCodec = null;
      //find the correct Codec and specify its quality
      EncoderParameter epQuality = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 100L);
      // Get all image codecs that are available
      ImageCodecInfo[] iciCodecs = ImageCodecInfo.GetImageEncoders();
      // Store the quality parameter in the list of encoder parameters
      EncoderParameters epParameters = new EncoderParameters(1);
      epParameters.Param[0] = epQuality;
      // Loop through all the image codecs
      for (int i = 0; i < iciCodecs.Length; i++)
      {
        // Until the one that we are interested in is found, which is image/jpeg
        if (iciCodecs[i].MimeType == "image/jpeg")
        {
          iciJpegCodec = iciCodecs[i];
          break;
        }
      }

      using (Graphics gr = Graphics.FromImage(bmp))
      {
        gr.DrawImage(image, new Rectangle(0, 0, bmp.Width, bmp.Height));
        gr.DrawString(pWatermark, new Font("Arial", 10), Brushes.White, new PointF(5, bmp.Height - 20));
      }

      bmp.Save(pPath + "test", iciJpegCodec, epParameters);
      bmp.Dispose();
    }       

Thank you very much. Just in case people don't know, to display the image, you need something like a picturebox- in this case, just drag a picturebox control onto your form, then simple use

pictureBox1.Image = myBitmap;

after all the code from this tutorial to display it.

hi dear! very teribble in the iran very simple designed by our student.

I do not know how to thank you

Thank you very much

Hi there,

I wondered if there was a way to insert an "Editable" text box inside of an image with the use of C#??

Let me explain: I would like to create an image that would allow the user to insert text, such as the image name, into the image at any time.

Thanks for answering!

Hi

Thanks for the code works great. I would like to know if i wanted to select a default image as background and also add text as described above i would also like to add another smaller image also to the default image (I am trying to create a weather image with a background, text for tempture, and second image(smaller one) as the weather condition i.e. sun, or moon, or rain). how can i add the second image could you provide a sample snippet of code??

a small but very useful bunch of code... just what i was lookin... thanx man...!!!

Nice and quick, perfect! Cheers

any way to get the source as a solution file?

What are gud job. thanks

Not working with me :S

This is my test code

Bitmap myBitmap = new Bitmap("G:\\myImage.jpg"); Graphics g = Graphics.FromImage(myBitmap);

g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias; g.DrawString("My\nText", new Font("Tahoma", 50), Brushes.White, new PointF(0, 0));

Hi.... I am windows developer

I am also doing same but my problem is that when i take print of document in which i have use watermark. The watermark color is dark as like other strings. It is happening because printer treat it as normal text. I want to know is there anyway to tell Printer to draw watermark light.

Thanks.

Great..
