Testing out Aspose.NET on Mono/C# and running into the following error when trying to do a simple conversion of spreadsheet to image.
A null reference or invalid value was found [GDI+ status: InvalidParameter]
Tried in every available .NET target framework with no luck. Running on Ubuntu 16.04 LTS.
Tried the exact same code on Visual Studio 2015 Windows 10 and it worked fine.
Appears to be some kind of issues with GDI on linux- any insight would be greatly appreciated.
Code below.
using System;
using Aspose.Cells;
using Aspose.Cells.Rendering;
using System.Drawing;
namespace annotate
{
class MainClass
{
public static void Main (string[] args)
{
Workbook workbook = new Workbook ("crocodoc.ods");
Worksheet sheet = workbook.Worksheets[0];
Aspose.Cells.Rendering.ImageOrPrintOptions options = new Aspose.Cells.Rendering.ImageOrPrintOptions();
options.HorizontalResolution = 200;
options.VerticalResolution = 200;
options.ImageFormat = System.Drawing.Imaging.ImageFormat.Tiff;
SheetRender sr = new SheetRender (sheet, options);
for (int j = 0; j < sr.PageCount; j++)
{
sr.ToImage(j, "test" + sheet.Name + " Page" + (j + 1) + ".out.tif");
}
}
}
}
