I use Spire.xls 7.9 (the last from Nuget)
I write a desktop program Windows Form C# NET 4.52 with Visual studio 2017
and i write also a windows WEB application C# NET 4.52 with Visual studio 2017.
They do the same thing: open a file XLS with image on the Header (png or jpg) and then save it in pdf format.
the code is like this:
Workbook workbook = new Workbook();
workbook.LoadFromFile(filexls,ExcelVersion.Version2010);
workbook.SaveToFile(filepdf, FileFormat.PDF);
For web application i use MVC architecture and ActionLink in the controller to show the result
I have check the program on more PC, windows 7 o windows server R2012 with IIS 8
I have different result:
-on my pc (windows 7) all seems work correctly in debug and release mode: WEB app and desktop app produced a PDF with header correct (image OK)
-on one PC server R12 without(?) other program: WEB app and desktop app NOT produced a PDF with header correct (the images are stretched along the file)
-on another PC windows server R12 WITH other pgm: WEB app NOT produced a PDF with header correct but the desktop app produced a PDF with header correct
What is the problem? Spire needs some prerequisite installed?
