كيفية تحويل كتيب عمل Excel الكامل إلى صورة في C#

dotnet add package Aspose.Cells

Workbook workbook = new Workbook("Book1.xlsx");

ImageOrPrintOptions options = new ImageOrPrintOptions
{
    ImageType = ImageType.Png,
    OnePagePerSheet = true,
    HorizontalResolution = 200,
    VerticalResolution = 200
};

WorkbookRender renderer = new WorkbookRender(workbook, options);

for (int i = 0; i < renderer.PageCount; i++)
{
    string fileName = $"workbook_page_{i + 1}.png";
    renderer.ToImage(i, fileName);
}

// Output:
// workbook_page_1.png
// workbook_page_2.png
// ...

// Example: show gridlines
options.ShowGridLines = true;

// Example: render the entire sheet content in one page
options.AllColumnsInOnePagePerSheet = true;
