Hi Renata,

It works fine for me here using the code below. Can you please test if this works for you? Otherwise, could you please send us an example we can run "as-is" to reproduce the problem here? You can post your files at [url]news://www.steema.net/steema.public.attachments[/url] newsgroup.

BTW: Don't forget to mention which TeeChart version you are using.

Code: Select all

tChart1.Export.Image.Metafile.Save(@"c:\temp\metafilebug.emf");

Hello Narcís Calvet,
The email that I sent you returned.
The steps below will generate the tchart with the black border:

1 - I created the form;
2 - I put a panel in form;
3- I put the TeeChart in panel and dock it;
4 - In form load I put this code:
private void Form1_Load(object sender, System.EventArgs e) {
tChart1.Header.Visible = true;
tChart1.Header.Text = "Test";
Steema.TeeChart.Styles.Line line = new Steema.TeeChart.Styles.Line();
line.FillSampleValues(10);
tChart1.Series.Add(line);
}
5 - Click button event I saved the TeeChart
private void button1_Click(object sender, System.EventArgs e) {
MemoryStream stream = new MemoryStream();
tChart1.Metafile.Save(stream,ImageFormat.Jpeg);
Image image = Image.FromStream(stream);
image.Save(@"C:\teste1.bmp",ImageFormat.Jpeg);
}

So Thanks,
Renata

Hi Renata,

I could reproduce what you reported using your code. However, the appropiate way of doing that and what works fine is using:

Code: Select all

		private void button1_Click_1(object sender, System.EventArgs e)
		{
			tChart1.Export.Image.JPEG.Save(@"C:\teste1.jpg");
		}

Hi Narcís Calvet,
Thanks, but I need metafile image, because the quality is better.
Do you have any idea how I can print metafile image?

So Thanks,
Renata

Hi Renata,

Then you can use:

Code: Select all

			tChart1.Export.Image.Metafile.Save(@"C:\temp\teste1.emf");

.

However if you want to print the chart you can do it directly with TeeChart routines as it internally uses a metafile as explained here so you could do:

Code: Select all

		private void button1_Click(object sender, System.EventArgs e)
		{
      tChart1.Printer.Preview();
		}
