we just upgraded to the Q3 2010 release of Aspose.Total. We have some existing code where we need to create a thumbnail image of the first page of some word, excel or powerpoint documents.
The way the thumbnail looks is not an exact reprensentation of the document in some cases and in others the save to an image functionality errors out altogether with an "object not defined" type error.
I have attached the original documents and the result thumbnails for your review.
here are code snippets of what we are doing for word and excel. These were taken from code examples you provided or from the your forum.
Document doc = new Document(inputname);
ImageSaveOptions options = new ImageSaveOptions(Aspose.Words.SaveFormat.Png);
options.PageCount = 1;
options.PageIndex = 0;
options.Resolution = 96;
Workbook book = new Workbook();
Worksheet sheet = book.Worksheets;
//Convert the worksheet to image.
System.Drawing.Bitmap bitmap = sheet.SheetToImage();
//Save the image file specifying its image format.
