Save Chart to Jpeg Border problem (regression from version2)

qcrnd · Post by **qcrnd** » Sun Apr 19, 2009 5:50 am

Hi
I noticed a regression from version 2. When saving a chart to a jpeg there is a always a border surrounding the jpeg even if the chart itself doesnt have a border. This didnt happen in version 2.
This causes a problem in documents that i create that have the charts embedded.

I have uploaded a sample TChartV3Tester.zip that save a chart into jpeg (just click the save jpeg button)
Please take the second upload , the first one has an illegal reference.
Please help
Thanks

Hi Narcis
Thanks for the response. Please raise the priority since we now have regressions in our application which do not look good .
Thanks.

Hello gcrnd,

We found that this bug [TF02014091], is not a bug, and you could solve your issue using next code:

Code: Select all

    private void button1_Click(object sender, EventArgs e)
    {
        Steema.TeeChart.Export.JPEGFormat jpeg = Chart.Export.Image.JPEG;
        jpeg.Width *= 2;
        jpeg.Height *= 2;
        bool oldBuffer = Chart.Graphics3D.UseBuffer;
        Chart.Graphics3D.UseBuffer = false;
        jpeg.Save(@"C:\test2.jpg");
        Chart.Graphics3D.UseBuffer = oldBuffer;
    
    }

I hope you will help.

Thanks,
