With Spire.PDF for .NET, developers can set page size for PDF in C#. This article will demonstrates how to get the PDF page size using Spire.PDF.
Detail steps:
Step 1: Create a PdfDocument instance and load the sample.pdf file.
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Sample.pdf");
Step 2: Get the width and height of the first page in the PDF file.
PdfPageBase page = doc.Pages[0]; float pointWidth = page.Size.Width; float pointHeight = page.Size.Height;
Step 3: Convert the size with other measurement unit, such as in Inch, Centimeter, Unit or Pixel.
//Create PdfUnitConvertor to convert the unit PdfUnitConvertor unitCvtr = new PdfUnitConvertor(); //Convert the size with "pixel" float pixelWidth = unitCvtr.ConvertUnits(pointWidth, PdfGraphicsUnit.Point, PdfGraphicsUnit.Pixel); float pixelHeight = unitCvtr.ConvertUnits(pointHeight, PdfGraphicsUnit.Point, PdfGraphicsUnit.Pixel); //Convert the size with "inch" float inchWidth = unitCvtr.ConvertUnits(pointWidth, PdfGraphicsUnit.Point, PdfGraphicsUnit.Inch); float inchHeight = unitCvtr.ConvertUnits(pointHeight, PdfGraphicsUnit.Point, PdfGraphicsUnit.Inch); //Convert the size with "centimeter" float centimeterWidth = unitCvtr.ConvertUnits(pointWidth, PdfGraphicsUnit.Point, PdfGraphicsUnit.Centimeter); float centimeterHeight = unitCvtr.ConvertUnits(pointHeight, PdfGraphicsUnit.Point, PdfGraphicsUnit.Centimeter);
Step 4: Save to a .txt file.
//Create StringBuilder to save
StringBuilder content = new StringBuilder();
//Add pointSize string to StringBuilder
content.AppendLine("The page size of the file is (width: " + pointWidth + "pt, height: " + pointHeight + "pt).");
content.AppendLine("The page size of the file is (width: " + pixelWidth + "pixel, height: " + pixelHeight + "pixel).");
content.AppendLine("The page size of the file is (width: " + inchWidth + "inch, height: " + inchHeight + "inch).");
content.AppendLine("The page size of the file is (width: " + centimeterWidth + "cm, height: " + centimeterHeight + "cm.)");
String output = "GetPageSize_out.txt";
//Save them to a txt file
File.WriteAllText(output, content.ToString());
Output:

How to Mannually Add Spire.Doc as Dependency in a .NET Standard Library Project
2019-10-22 09:02:07 Written by KoohjiAs System.Drawing only supported on Windows in NET6.0, you need to use SkiaSharp instead under NET5.0 or NET6.0 in Linux, or inside docker container. Please follow the next steps to use the NetStandard dlls to get SkiaSharp to your project manually. We will use Spire.Doc as example.
Step 1: Download the latest version of Spire.Doc Pack from this link, unzip it, and you'll get the DLL files for .NET Standarad from the "netstandard2.0" folder or install via NuGet.
PM> Install-Package Spire.Officefor.NETStandard
If you already have this folder in your disk, go straight to step two.
Step 2: Create a .NET Standard library project in your Visual Studio.
Step 3: Add all DLL files under the "netstandard2.0" folder as dependencies in your project.
Right-click "Dependencies" – select "Add Reference" – click "Browse" – selcet all DLLs under "netstandard2.0" folder – click "Add".
Step 4: Install the other three packages in your project via the NuGet Package Manager. They are SkiaSharp, System.Text.Encoding.CodePages and System.Security.Cryptography.Xml.
Right-click "Dependencies" – select "Manage NuGet Packages" – click "Browse" – type the package name – select the package from the search results – click "Install".
Step 5: Now that you've added all the dependences successfully, you can start to write your own .NET Standard library that is capable of creating and processing Word documents.
using Spire.Doc;
using Spire.Doc.Documents;
namespace SpireDocStandard
{
public class Class1
{
public void CreateWord()
{
//Create a document object
Document doc = new Document();
//Add a section
Section section = doc.AddSection();
//Add a paragrah
Paragraph paragraph = section.AddParagraph();
//Append text to the paragraph
paragraph.AppendText("Hello World");
//Save to file
doc.SaveToFile("Output.docx", FileFormat.Docx2013);
}
}
}
This article demonstrates how to add data labels to a chart and set the appearance (border style and fill style) for the data labels in PowerPoint using Spire.Presentation for Java. Note some chart types like Surface3D, Surface3DNoColor, Contour and ContourNoColor do not support data labels.
Below screenshot shows the original chart before adding data labels:
import com.spire.presentation.FileFormat;
import com.spire.presentation.ISlide;
import com.spire.presentation.Presentation;
import com.spire.presentation.charts.IChart;
import com.spire.presentation.charts.entity.ChartDataLabel;
import com.spire.presentation.charts.entity.ChartSeriesDataFormat;
import com.spire.presentation.drawing.FillFormatType;
import java.awt.*;
public class AddDataLabelsToChart {
public static void main(String[] args) throws Exception {
//Load the PowerPoint document
Presentation ppt = new Presentation();
ppt.loadFromFile("Chart.pptx");
//Get the first slide
ISlide slide = ppt.getSlides().get(0);
//Get the chart in the slide
IChart chart = (IChart)slide.getShapes().get(0);
//Loop through the series in the chart
for (ChartSeriesDataFormat series:(Iterable<ChartSeriesDataFormat>)chart.getSeries()) {
) {
//Add data labels for the data points in each series
for(int i = 0; i < 4; i++){
ChartDataLabel dataLabel = series.getDataLabels().add();
//Show label value
dataLabel.setLabelValueVisible(true);
//Show series name
dataLabel.setSeriesNameVisible(true);
//Set border line style
dataLabel.getLine().setFillType(FillFormatType.SOLID);
dataLabel.getLine().getSolidFillColor().setColor(Color.RED);
//Set fill style
dataLabel.getFill().setFillType(FillFormatType.SOLID);
dataLabel.getFill().getSolidColor().setColor(Color.YELLOW);
}
}
//Save the resultant document
ppt.saveToFile("DataLabels.pptx", FileFormat.PPTX_2013);
}
}
Output:
