A 100% stacked bar chart is a chart type designed to show the relative percentage of multiple data series in stacked bars, where the total of each stacked bar always equals 100%. This article will demonstrate how to use Spire.Presentation to create 100% stacked bar in PowerPoint in C#.
Step 1: Create a Presentation object.
Presentation presentation = new Presentation();
Step 2: Add a "Bar100PercentStacked" chart to the first slide.
presentation.SlideSize.Type = SlideSizeType.Screen16x9; SizeF slidesize = presentation.SlideSize.Size; var slide = presentation.Slides[0]; RectangleF rect = new RectangleF(20, 20, slidesize.Width - 40, slidesize.Height - 40); IChart chart = slide.Shapes.AppendChart(Spire.Presentation.Charts.ChartType.Bar100PercentStacked, rect);
Step 3: Write data to the chart data.
string[] columnlabels = { "Series 1", "Series 2", "Series 3" };
// Insert the column labels
String[] cols = columnlabels.ToArray();
for (Int32 c = 0; c < cols.Count(); ++c)
chart.ChartData[0, c + 1].Text = cols[c];
string[] rowlabels = { "Category 1", "Category 2", "Category 3" };
// Insert the row labels
String[] rows = rowlabels.ToArray();
for (Int32 r = 0; r < rows.Count(); ++r)
chart.ChartData[r + 1, 0].Text = rows[r];
double[,] values = new double[3, 3] { { 20.83233, 10.34323, -10.354667 }, { 10.23456, -12.23456, 23.34456 }, { 12.34345, -23.34343, -13.23232 }};
// Insert the values
double value = 0.0;
for (Int32 r = 0; r < rows.Count(); ++r)
{
for (Int32 c = 0; c < cols.Count(); ++c)
{
value = Math.Round(values[r, c], 2);
chart.ChartData[r + 1, c + 1].Value = value;
}
}
chart.Series.SeriesLabel = chart.ChartData[0, 1, 0, columnlabels.Count()];
chart.Categories.CategoryLabels = chart.ChartData[1, 0, rowlabels.Count(), 0];
chart.PrimaryCategoryAxis.Position = AxisPositionType.Left;
chart.SecondaryCategoryAxis.Position = AxisPositionType.Left;
chart.PrimaryCategoryAxis.TickLabelPosition = TickLabelPositionType.TickLabelPositionLow;
Step 4: Set the data, font and format for the series of each column.
for (Int32 c = 0; c < cols.Count(); ++c)
{
chart.Series[c].Values = chart.ChartData[1, c + 1, rowlabels.Count(), c + 1];
chart.Series[c].Fill.FillType = FillFormatType.Solid;
chart.Series[c].InvertIfNegative = false;
for (Int32 r = 0; r < rows.Count(); ++r)
{
var label = chart.Series[c].DataLabels.Add();
label.LabelValueVisible = true;
chart.Series[c].DataLabels[r].HasDataSource = false;
chart.Series[c].DataLabels[r].NumberFormat = "0#\\%";
chart.Series[c].DataLabels.TextProperties.Paragraphs[0].DefaultCharacterProperties.FontHeight = 12;
}
}
chart.Series[0].Fill.SolidColor.Color = Color.YellowGreen;
chart.Series[1].Fill.SolidColor.Color = Color.Red;
chart.Series[2].Fill.SolidColor.Color = Color.Green;
TextFont font = new TextFont("Tw Cen MT");
Step 5: Set the font and size for chartlegend.
for (int k = 0; k < chart.ChartLegend.EntryTextProperties.Length; k++)
{
chart.ChartLegend.EntryTextProperties[k].LatinFont = font;
chart.ChartLegend.EntryTextProperties[k].FontHeight = 20;
}
Step 6: Save the document to file.
presentation.SaveToFile("Sample.pptx", FileFormat.Pptx2010);

Spire.PDF supports to print a PDF in greyscale. This article is going to show you how to use Spire.PDF to accomplish this function.
Below is the example PDF file we used for demonstration:
Detail steps:
Step 1: Create a PdfDocument instance and load the PDF file.
PdfDocument pdf = new PdfDocument(); pdf.LoadFromFile(@"Stories.pdf");
Step 2: Set the PdfPrintSettings.Color property to false.
pdf.PrintSettings.Color = false;
Step 3: Print the document.
pdf.Print();
Screenshot after printing to xps:
Full code:
using Spire.Pdf;
namespace Print_PDF_in_Black_and_White
{
class Program
{
static void Main(string[] args)
{
PdfDocument pdf = new PdfDocument();
pdf.LoadFromFile(@"Stories.pdf");
pdf.PrintSettings.Color = false;
pdf.Print();
}
}
}

Shadows make your shapes or pictures especially with transparent background pop out of your slide. They make flat 2 dimensional graphics look like 3 dimensional graphics. This article will show you how we can apply shadow effects to shapes and pictures in PowerPoint using Spire.Presentation.
Apply Shadow Effect to Shape
using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;
namespace ApplyShadoweffect
{
class Program
{
static void Main(string[] args)
{
{
//Create a Presentation object and get the first slide.
Presentation ppt = new Presentation();
ISlide slide = ppt.Slides[0];
//Add a shape to slide.
RectangleF rect = new RectangleF(30, 80, 300, 120);
IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, rect);
shape.Fill.FillType = FillFormatType.Solid;
shape.Fill.SolidColor.Color = Color.LightBlue;
shape.Line.FillType = FillFormatType.None;
shape.TextFrame.Text = "This demo shows how to apply shadow effect to shape.";
shape.TextFrame.TextRange.Fill.FillType = FillFormatType.Solid;
shape.TextFrame.TextRange.Fill.SolidColor.Color = Color.Black;
//Create an inner shadow effect through InnerShadowEffect object.
InnerShadowEffect innerShadow = new InnerShadowEffect();
innerShadow.BlurRadius = 20;
innerShadow.Direction = 0;
innerShadow.Distance = 0;
innerShadow.ColorFormat.Color = Color.Black;
//Apply the shadow effect to shape.
shape.EffectDag.InnerShadowEffect = innerShadow;
//Save to file.
ppt.SaveToFile("ShadowOnShape.pptx", FileFormat.Pptx2010);
}
}
}
}
Apply Shadow Effect to Picture
using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;
namespace ApplyShadoweffect
{
class Program
{
static void Main(string[] args)
{
{
//Create a Presentation object and get the first slide.
Presentation ppt = new Presentation();
ISlide slide = ppt.Slides[0];
//Get the picture path.
string imagePath = "dinosaur.png";
Image image = Image.FromFile(imagePath);
float width = (float)image.Width / 3;
float height = (float)image.Height / 3;
//Add a shape to slide and fill the shape with picture.
RectangleF rect = new RectangleF(80, 80, width, height);
IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, rect);
shape.Fill.FillType = FillFormatType.Picture;
shape.Fill.PictureFill.Picture.Url = imagePath;
shape.Fill.PictureFill.FillType = PictureFillType.Stretch;
shape.Line.FillType = FillFormatType.None;
//Choose a preset shadow effect.
PresetShadow presetShadow = new PresetShadow();
presetShadow.Preset = PresetShadowValue.BackLeftPerspective;
presetShadow.ColorFormat.Color = Color.LightGray;
//Apply the shadow effect to shape.
shape.EffectDag.PresetShadowEffect = presetShadow;
//Save to file.
ppt.SaveToFile("ShadowOnPicture.pptx", FileFormat.Pptx2010);
}
}
}
