Bubble chart image doesn't created properly in PPT


We are trying to create a worksheet image in PPT from a workbook by using the following code. But in the PowerPoint slide the image of bubble chart only shows bubbles which has the positive Y Axis values. Other bubbles are not shown.

public static Image GetWorksheetImage(this Workbook workbook, string sheetName = “”, int pageIndex = 0)
var iop = new ImageOrPrintOptions
IsCellAutoFit = false,
ImageFormat = ImageFormat.Emf,
VerticalResolution = 96,
HorizontalResolution = 96,
Quality = 100,
OnePagePerSheet = true,
OnlyArea = true,
SaveFormat = SaveFormat.Auto,
ChartImageType = ImageFormat.Emf
//SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.Default

var sheet = string.IsNullOrWhiteSpace(sheetName)
? workbook.Worksheets[workbook.Worksheets.ActiveSheetIndex]
: workbook.Worksheets[sheetName];

var sr = new SheetRender(sheet, iop);
var imgOleObject = sr.ToImage(pageIndex);

return imgOleObject;

The Worksheet(Template.xlsx) with bubble chart has been attached with this post which we want to convert to image in PPT slide. But in slide only bubbles which has positive Y Axis value are shown. Other bubbles are not shown.

Need help and feedback urgently regarding this…

Hi Mandy,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thank you
for sharing the sample file.<o:p></o:p>

I checked
your file and it looks like your issue is related to worksheet to image
conversion feature of Aspose.Cells. The image generated with Aspose.Cells
doesn’t have the negative value bubbles in the chart. I am moving this thread
to Aspose.Cells forum where one of my colleagues will further assist you
regarding your issue.<o:p></o:p>

& Regards,


Thanks for the template file.

After an initial test, I observed the issue by rendering the image of the first sheet (containing the chart) in the template file to image format. In the output image, the bubble chart only shows bubbles which has the positive Y Axis values as you pointed out.
Sample code:

ImageOrPrintOptions iop = new ImageOrPrintOptions();
iop.OnePagePerSheet = true;
iop.ChartImageType = ImageFormat.Emf;

Workbook workbook = new Workbook(“e:\test2\Template.xlsx”);
Worksheet worksheet = workbook.Worksheets[0];
SheetRender sr = new SheetRender(worksheet, iop);
sr.ToImage(0, “e:\test2\out1.emf”);
