I the excel file (image_brightness.xlsx) I have an image with high brightness set. Rendering the file content with the image as a image losses the brightness setting. (see image_brightness.xlsx.out.png file)
The code used to obtain the image file is :
const string filePath = @“C:\image_brightness.xlsx”;
var workbook = new Workbook(filePath);
var imageOptions = new ImageOrPrintOptions
Quality = 100,
VerticalResolution = 200,
HorizontalResolution = 200,
PrintingPage = PrintingPageType.IgnoreBlank,
ImageFormat = ImageFormat.Png,
OnePagePerSheet = true
var worksheet = workbook.Worksheets;
string printArea = string.Format(“D2:T42”);
worksheet.PageSetup.PrintArea = printArea;
worksheet.PageSetup.TopMargin = 0;
worksheet.PageSetup.LeftMargin = 0;
worksheet.PageSetup.RightMargin = 0;
worksheet.PageSetup.BottomMargin = 0;
var sheetRender = new SheetRender(worksheet, imageOptions);
sheetRender.ToImage(0, filePath + “.out.png”);
