Render Chart in code and draw to PDF

[Victor Dienstbier]

Hi!

Since some time now I'm trying to create a SfChart in code behind (without showing it in UI) and draw this chart on an newly created PDF File. I've had a lot of help from the forum but I wasn't able to find any clue to solve my problem. It's meant to be for a protocol.

The PDF is created and there is some kind of blank square where the chart should be and the size seems to be correct.

Please help me to solve the problem!

Thank you very much!

The example code looks like this:

public static void ProtokollErstellen(Pumpenmessdaten.MessungenSammlung MessdatenSammlung)

{

PdfDocument document = new PdfDocument();

document.PageSettings.Size = PdfPageSize.A4;

document.PageSettings.Margins.All = 10;

PdfPage page = document.Pages.Add();

PdfGraphics graphics = page.Graphics;

SfChart chart = new SfChart()

{

Header = "Kennlinie"

};

NumericalAxis primaryAxis = new NumericalAxis()

{

Header = "Volumenstrom [l/s]",

ShowTrackBallInfo = true

};

chart.PrimaryAxis = primaryAxis;

//Adding vertical axis to the chart

NumericalAxis Axis1 = new NumericalAxis()

{

Header = "Förderhöhe [m]",

ShowTrackBallInfo = true

};

chart.SecondaryAxis = Axis1;

PdfBitmap bmpChart = new PdfBitmap(RenderChartToImage(chart));

page.Graphics.DrawImage(bmpChart, 0, 150);

document.Save(sDateiname);

System.Diagnostics.Process.Start(sDateiname);

}

private static Image RenderChartToImage(SfChart chart)

{

chart.RenderSize = new System.Windows.Size(500, 500);

RenderTargetBitmap renderBitmap =

new RenderTargetBitmap(

(int)chart.RenderSize.Width,

(int)chart.RenderSize.Width,

96,

96,

PixelFormats.Pbgra32);

renderBitmap.Render(chart);

using (MemoryStream outStream = new MemoryStream())

{

//Chart is saved in memorystream

chart.Save(outStream, new PngBitmapEncoder());

Image image = Image.FromStream(outStream);

return image;

}

}

Hi Victor, 

  

Thanks for contacting Syncfusion Support, 

  

We are able to achieve your requirement (without showing the chart in UI) by measuring the chart size. We have prepared a demo sample based on your requirement and it can be downloaded from below link, 

  

Sample: ChartToPDF(2)

Hi Devi!

Thank you very much for your help! It works great...

I have some more questions  ;-)

Is it somehow possible to increase the quality of the chart? It kind of looks very low quality... Or is there even the possibility to make a chart on a PDF which is interactive?

Thank you very much!

Victor

Hi Victor, 

  

Thanks for your update. 

  

By default, we are rendering the HighQuality image with the RenderTargetBitmap’s RenderOption. However, we are able to achieve your requirement (high quality image) by increasing the chart size (same size set to exported image). We have modified the sample based on your requirement and it can be downloaded from below link, 

  

Sample: ImageModified

Hi Devi!

Thanks again for your help!

Unfortunately it doesn't seem to improve the quality of the image for me! I've tried everything... I don't know either why I can't use BmpBitmapEncoder(). For me only the PngBitmapEncoder() works without showing an error :-(

I added an example protocoll to show you what I mean...

Is there anything else I can do? The most awesome thing would of course be some kind of plugin for Charts in the PDF to use it like in an App. To have the ability to zoom etc. Is this even possible?

Thank you very much for your help!

Victor

Hi Victor, 

  

Thanks for your update. 

  

Query 1: why I can't use BmpBitmapEncoder() 

  

As we are unable to reproduce the reported problem at our end, please provide more information regarding the error occurred, like screenshot and the information regarding your machine 

  

Query 2: some kind of plugin for Charts in the PDF to use it like in an App. 

  

We don’t have support to use chart in pdf as plugin.

Do you need any more information?

I also made some screenshots of the error. Are they helping?

Maybe you can consider to add such a feature (PDF addIns) in the future! I think alot of people would be amazed to have something like that :-)

Have a great day and I hope the information are enough and you can help me with these :-)

Hi Victor,

Thanks for your update.

When we look at the updated error screenshots, it seems system related issue. Since BmpBitmapEncoder issue occurred in System.Drawing assemblies.
For PDF plugin, we will analyze the feasibility to include this support.

M. Sheik
