Add Pictures to Word Documents in C# and VB.NET

A Picture element is a type of Shape element that contains an image. GemBox.Document supports pictures of various PictureFormats like PNG, JPEG, GIF, TIFF, SVG, EMF and WMF. This element allows you to add pictures to your Word documents using C# and VB.NET

Pictures can be inline (of InlineLayout type), in which case the position of an image is constrained to the lines of text on the page. Alternatively, they can be floating (of FloatingLayout type), in which case they can be positioned anywhere on the page.

You can read more about this on the Shapes and Layout help page.

You can replace an image data using the Picture.PictureStream property. Images in SVG format are rendered in PDF files as vector graphics, resulting in smaller file sizes and better quality than bitmap images.

The example below shows how to create pictures of different formats, sizes, and positions.

        var document = new DocumentModel();

        var section = new Section(document);
        document.Sections.Add(section);

        var paragraph = new Paragraph(document);
        section.Blocks.Add(paragraph);

        // Create and add an inline picture with GIF image.
        Picture picture1 = new Picture(document, "%#Zahnrad.gif%", 61, 53, LengthUnit.Pixel);
        paragraph.Inlines.Add(picture1);

        // Create and add a floating picture with PNG image.
        Picture picture2 = new Picture(document, "%#Dices.png%");
        FloatingLayout layout2 = new FloatingLayout(
            new HorizontalPosition(HorizontalPositionType.Left, HorizontalPositionAnchor.Page),
            new VerticalPosition(2, LengthUnit.Inch, VerticalPositionAnchor.Page),
            picture2.Layout.Size);
        layout2.WrappingStyle = TextWrappingStyle.InFrontOfText;

        picture2.Layout = layout2;
        paragraph.Inlines.Add(picture2);

        // Create and add a floating picture with SVG image.
        Picture picture3 = new Picture(document, "%#Graphics1.svg%", 400, 200, LengthUnit.Pixel);

Even though GemBox.Document provides quite a few Picture constructors that can enable you to specify the element's size and layout, you can also resize the element after inserting it into a document with the Picture.Layout.Size property.

The following example shows how you can add large images and resize them to fit the document's page.

using System;
using GemBox.Document;

class Program
{
    static void Main()
    {
        // If using Professional version, put your serial key below.
        ComponentInfo.SetLicense("FREE-LIMITED-KEY");

        var document = new DocumentModel();

        var section = new Section(document);
        document.Sections.Add(section);

        var picture = new Picture(document, "%#Jellyfish.jpg%");
        section.Blocks.Add(new Paragraph(document, picture));

        var pictureLayout = picture.Layout;
        var pictureSize = pictureLayout.Size;

        var pageSetup = section.PageSetup;
        var pageSize = new Size(
            pageSetup.PageWidth - pageSetup.PageMargins.Left - pageSetup.PageMargins.Right,
            pageSetup.PageHeight - pageSetup.PageMargins.Top - pageSetup.PageMargins.Bottom);

        double ratioX = pageSize.Width / pictureSize.Width;
        double ratioY = pageSize.Height / pictureSize.Height;
        double ratio = Math.Min(ratioX, ratioY);

        // Resize picture element's size.
        if (ratio < 1)
            pictureLayout.Size = new Size(pictureSize.Width * ratio, pictureSize.Height * ratio);

        document.Save("LargePicture.%OutputFileType%");
    }
}
Imports System

        Dim section As New Section(document)

        Dim picture As New Picture(document, "%#Jellyfish.jpg%")

        Dim ratioX As Double = pageSize.Width / pictureSize.Width
        Dim ratioY As Double = pageSize.Height / pictureSize.Height
        Dim ratio As Double = Math.Min(ratioX, ratioY)

        ' Resize picture element's size.
        If ratio < 1 Then
            pictureLayout.Size = New Size(pictureSize.Width * ratio, pictureSize.Height * ratio)
        End If

        document.Save("LargePicture.%OutputFileType%")

    End Sub
