Exporting To PDF

Hi,

I'm trying to place an exported chart into a pdf document.

I've succeeded in doing this, but the quality of the chart is not very clear and are a bit blurred, especially the labels and lines.

I've tested exporting as jpeg and png but there is no difference in the result. I've also tested between exporting as file and memory stream, but no difference.

Is there a way that I can enhance the quality and readibility of the chart?

I'm using iTextSharp to create the pdf documents, TeeChart 3.0 for charting and VS 2005.

Thanks
Regards

Hi cjherasmus,

Are you exporting the charts as shown in Tutorial 12 - Exporting and Importing Charts and latest TeeChart for .NET v3 available at the client area? You'll find the tutorials at TeeChart's program group.

If the problem persists please send us a simple example project we can run "as-is" to reproduce the problem here. You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance!

Narcis,

I am following the way it is explained in the tutorial. I'm also using the latest version of TeeChart 3. I cannot send you the code, for it's an extremely large project which has many dependencies on other technology and databases. I also have not the time to produce a smaller example due to budget constraints, etc.

My question is to the export of a chart to an image and any way how to improve the quality. I'll upload you an export of a jpeg chart so that you can see the quality. That's unfortunately all I can do. The file name is "chart_quality.jpg"

Thanks

Hi cjherasmus,

As you can see in the tutorial, you can set the Quality property for jpg files. Have you tried setting it to 100?

Thanks in advance.

I've tried the Quality property but it didn't make a difference. Maybe it is because of the anti-aliasing I'm using?
