With Spire.Doc, we can set the formats for paragraph in C#. This article will focus on demonstrate how to set the spacing before and after the paragraph in C#.
Set the spacing before and after the paragraph for a newly added paragraph added by the method of paragraph.AppendHTML() to a new blank word document.
//create a new word document and add a section and paragraph to it.
Document doc = new Document();
Section sec = doc.AddSection();
Paragraph para = sec.AddParagraph();
//Add the text strings to the paragraph and set the style
para.AppendHTML("Add a new paragraph to the word and set the spacing
");
para.ApplyStyle(BuiltinStyle.Heading1);
//set the spacing before and after
para.Format.BeforeAutoSpacing = false;
para.Format.BeforeSpacing = 20;
para.Format.AfterAutoSpacing = false;
para.Format.AfterSpacing = 20;
//save the document to file
doc.SaveToFile("Result1.docx");
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
namespace SetSpacing
{
class Program
{
static void Main(string[] args)
{
//create a new word document and load the sample from file
Document document = new Document();
document.LoadFromFile("sample.docx", FileFormat.Docx);
//Add the text strings to the paragraph and set the style
Paragraph para = new Paragraph(document);
TextRange textRange1 = para.AppendText("This is a inserted paragraph.");
textRange1.CharacterFormat.TextColor = Color.Blue;
textRange1.CharacterFormat.FontSize = 15;
//set the spacing before and after
para.Format.BeforeAutoSpacing = false;
para.Format.BeforeSpacing = 10;
para.Format.AfterAutoSpacing = false;
para.Format.AfterSpacing = 10;
//insert the added paragraph to the word document
document.Sections[0].Paragraphs.Insert(1, para);
//save the document to file
document.SaveToFile("Result2.docx", FileFormat.Docx2010);
}
}

When creating a PDF layer, Spire.PDF allows developers to set an initial visibility state for the layer. While it also supports to change the visibility of existing layers in a PDF document. This article explains how to show or hide the existing layers using Spire.PDF.
PdfLayer.Visibility property is used to change the visibility of a PDF layer. To show a hidden layer, set the PdfLayer.Visibility property to PdfVisibility.On. To hide an existing layer, set the PdfLayer.Visibility to PdfVisibility.Off.
The following example shows how to hide a specific PDF layers:
using Spire.Pdf;
using Spire.Pdf.Graphics.Layer;
namespace HideLayer
{
class Program
{
static void Main(string[] args)
{
using (PdfDocument doc = new PdfDocument("AddLayers.pdf"))
{
//Hide the layer by index
doc.Layers[1].Visibility = PdfVisibility.Off;
//Hide the layer by Name
//doc.Layers["BlueLine"].Visibility = PdfVisibility.Off;
//Save the file
doc.SaveToFile("HideLayer.pdf");
}
}
}
}
To show or hide all of the layers:
using Spire.Pdf;
using Spire.Pdf.Graphics.Layer;
namespace ShowLayer
{
class Program
{
static void Main(string[] args)
{
using (PdfDocument doc = new PdfDocument("AddLayers.pdf"))
{
for (int i = 0; i < doc.Layers.Count; i++)
{
//Show all of the layers
//doc.Layers[i].Visibility = PdfVisibility.On;
//Hide all of the layers
doc.Layers[i].Visibility = PdfVisibility.Off;
}
//Save the file
doc.SaveToFile("HideAllLayers.pdf");
}
}
}
}

Spire.Doc supports to add new shape and shape group to the word document, it also supports to remove the shapes from the word. This article will show you how to reset the size of shape on an existing word document via Spire.Doc.
Firstly, view the original shape on the word document:
Step 1: Create a new instance of word document and load the document from file.
Document doc = new Document();
doc.LoadFromFile("Sample.docx",FileFormat.Docx2010);
Step 2: Get the first section and the third paragraph that contains the shape.
Section section = doc.Sections[0]; Paragraph para = section.Paragraphs[2];
Step 3: Get the shape and reset the width and height for the shape.
ShapeObject shape = para.ChildObjects[0] as ShapeObject; shape.Width = 400; shape.Height = 300;
Step 4: Save the document to file.
doc.SaveToFile("result.docx",FileFormat.Docx2010);
Effective screenshot of the shape after reset the size.
