Hi Telerik Team,

I have just created my first report, that contains a chart. Beside the chart the report has a TextBox control.

For the TextBox I have set as Font Arial and as FontSize 9,75pt.

I tried to set the same Font-Settings for the AxisLabel of the X and the Y Axis. It nearly seems to work, but the text shown on report differs. While the TextBox shows the text as expected the AxisLabels text is very grainy. I have the same problem with the text in the legend and the scales in the chart, too. What am I doing wrong.

Hi Peter,

Can you elaborate where do you observe the grainy effect? If it is when the file is exported to pdf, then would it have to do with the info of this blog post? Does the same thing occur if you use the standard RadChart for ASP.NET AJAX and a asp:Label/Textbox controls? Any additional information on the matter would be highly appreciated.

Best wishes,
Steve

I have now tried several things and my conclusion: It has to be the PDF (and other) Export Mechanism.
I took a look at my report in the ReportViewer and everything is as it should be. Very sharp, no blurring (even when zooming 500%). But as soon as I export to any format, the quality is terrible for any graphics included in the report. The text coming from TextBoxes look fine.
You can see the bad quality for example in the AxisLabels, or the lines in a Line Chart. The lines are then like steps which you can notice without zooming.

How can I make the PDF Rendering Mechanism export with a better quality?

Hi Telerik Team,

I have another question concerning the PDF Quality. Is it possible to somehow convert the chart not as bitmap but as vectors. I think that would rapidly increase the Quality of the Chart in the PDF?

Thanks in advance!

Hello Peter,

Once again we state that there is no problem with the chart quality in pdf compared to other export formats. There is no way for vector drawing of the charts in pdf, otherwise we would have implemented it. Please open a support ticket and provide us with a sample report with runnable chart where we can observe the quality problems you talk about. It is also not clear if you have reviewed the blog post we referred you to in our previous reply and what are your observations?

Regards,
Steve

Hi Steve,

1. I said that ANY export format is bad quality. Not only PDF. So if you compare them you surely won't see any difference.

2. I have reviewed your blog entry. Acrobat Reader already had the right setting due to a problem I had before, so that's not the reason. But except of that: I can't tell all my clients to change their Acrobat Reader settings. That makes an unprofessional tense to them. Especially because they are used to better quality from us. We used the free edition of Crystal Reports before which exports in vectors. So there is a brilliant chart on screen and on paper without the need to change any setting. But we are/were about to change to Telerik Reporting because it offers much more possibilities for settings. But all this possibilities don't help, if the final result is not good :-(.

3. How and where can I open a support ticket?

Thanks in advance and have a nice weekend

Hi Peter,

Do you find the quality of the chart in the Product Line Sales demo report unsatisfying? Using the same chart markup and the RadChart for ASP.NET AJAX control, the quality would is the same, so we're not sure if the problem is related to the chart item in Telerik Reporting.
I agree on the second point - it does sound unprofessional, but after all, Acrobat Reader is the tool they use to manage all their pdf files, so eventually they would have the fuzzy effect on other documents as well.
To open a support ticket, go to your Client.net account and go to Your Support --> Support tickets.
