Hello,
I have discovered multiple problems with saving a chart to an image:
- 3D bubble chart is rendered as 2D bubble chart
- Data labels are overlapped by other series in 3D chart with multiple series
- 3D rotation is not preserved
- Chart size is not preserved for radar charts
- Chart title font is reset to Calibri (Body). The reset happens also when opening and saving the workbook. Note that the chart font is reset only for certain font types (e.g: Algerian, Century, Cambria Math, Monotype Corsiva, Informal Roman).
The code used to generate the images is:
var opts = new Aspose.Cells.Rendering.ImageOrPrintOptions
{
Quality = 100,
HorizontalResolution = 200,
VerticalResolution = 200,
ImageFormat = ImageFormat.Png
};
image = chart.ToImage(opts);
Thank you,
