Aspose.Cells - 将工作表转换为图像

使用Ruby中的Aspose.Cells for Java将工作表转换为图像,只需调用Converter模块。

Ruby 代码

 def worksheet_to_image(workbook)

    #Create an object for ImageOptions

    img_options = Rjb::import('com.aspose.cells.ImageOrPrintOptions').new



    # Set the image type

    image_format = Rjb::import('com.aspose.cells.ImageFormat')

    img_options.setImageFormat(image_format.getPng())



    # Get the first worksheet.

    sheet = workbook.getWorksheets().get(0)

    # Create a SheetRender object for the target sheet

    sr = Rjb::import('com.aspose.cells.SheetRender').new(sheet, img_options)



    j = 0

    while j < sr.getPageCount()

        # Generate an image for the worksheet

        sr.toImage(j, @data_dir + "mysheetimg_#{j}.png")

        j +=1

    end

    puts "Image saved successfully."

end
