Worksheet to Image - Set Pixel Format for the Rendered Image

Sometimes you want to specify the pixel format when rendering a worksheet to image format. By default, Aspose.Cells uses 32 bits per pixel. Aspose.Cells allows you to customize the pixel format (bit depth) using options for the rendered image.

Please see the sample code below that demonstrates how to set the desired pixel format while rendering images of the sheets.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
//Source directory
string sourceDir = RunExamples.Get_SourceDirectory();

//Output directory
string outputDir = RunExamples.Get_OutputDirectory();

// Load an Excel file
Workbook wb = new Workbook(sourceDir + "sampleSetPixelFormatRenderedImage.xlsx");

//Access first worksheet
Worksheet ws = wb.Worksheets[0];

// Set the ImageOrPrintOptions with desired pixel format (24 bits per pixel) and image format type
ImageOrPrintOptions opts = new ImageOrPrintOptions();
opts.PixelFormat = PixelFormat.Format24bppRgb;
opts.ImageType = Drawing.ImageType.Tiff;

// Instantiate SheetRender object based on the first worksheet
SheetRender sr = new SheetRender(ws, opts);

// Save the image (first page of the sheet) with the specified options
sr.ToImage(0, outputDir + "outputSetPixelFormatRenderedImage.tiff");
