Chart.ToPDF Set Page Size

Hello,

Is there a way to set the desired output page size when using Chart.ToPDF?

Right now I am using it with memory streams and Aspose.Pdf.Facades.PdfFileEditor to concatenate just the charts (embedded or chart sheets) from a workbook into a single PDF. When using Chart.PDF, the resulting page in the PDF is the size of the chart.

Thanks,

Sheri

Thanks, @shakeel.faiz, I have been getting the emails.

We have looked into this issue and found that you can set width and height of the chart to the desired width and height, then render it to pdf.

Please see the section Chart Position and Size that explains how to change chart position and size.

Thanks, I’ll give it a try and see if it is what I am looking for.

I was able to change the size of the chart but what am really looking for is for the chart to be placed in the middle (or wherever) of a standard sized page such as Letter, similar to the output of a chart tab when using Workbook.Save.

I was able to work around this by creating new chart sheets and placing the embedded charts on them, and then using hidden sheets and Workbook.Save to get my results.

I found it odd that the ToPDF created pages sized to the charts; I was expected some sort of default paper size. It makes sense for ToImage to maintain the pixel size of the chart since you are going to an image and not a document.

Thanks for your posting and using Aspose APIs.

We are clear about your needs and we will add an API for it that will fulfill your requirements. Once, we will have some fix for you, we will update you in this topic asap.

@sheri_steeves,

Please try our latest version/fix: Aspose.Cells for Java v18.3.9.

We have fixed your issue now.

We added new APIs:

  • Chart.ToPdf(string fileName, float desiredPageWidth, float desiredPageHeight, PageLayoutAlignmentType hAlignmentType, PageLayoutAlignmentType vAlignmentType)
  • Chart.ToPdf(Stream stream, float desiredPageWidth, float desiredPageHeight, PageLayoutAlignmentType hAlignmentType, PageLayoutAlignmentType vAlignmentType)

e.g
Sample code:

Workbook wb = new Workbook(srcFile);

//Set Paper A4 size.
wb.Worksheets[0].Charts[0].ToPdf(outputPdfFile, 8.27f, 11.69f, PageLayoutAlignmentType.Center, PageLayoutAlignmentType.Center);

Let us know your feedback.

I’m using the .NET library - do you know when this will be migrated to the .Net version? The NuGet package is still on 18.3.0.

Thanks,

Sheri

@sheri_steeves,

Sorry, the previous fix was for Java. Please try our latest Aspose.Cells for .NET v18.3.9 for your needs.

Let us know your feedback.

Thanks, I’ve downloaded the zip and will try shortly.

Works great!

An automatic FitToPage and/or margins would also be great but that is also something I can easily calculate. Now my PDF looks good.
