Как создать документ с изображением на C# и .NET

  1. Добавьте SautinSoft.Document из Nuget.
  2. Создайте новый документ.
  3. Сохраните в формате изображения.

Давайте создадим простой документ в PNG формате с двумя абзацами, содержащими форматированный текст и графику, как показано на рисунке:

Простое изображение (PNG) документа

Здесь мы покажем Вам два способа создания одного и того же документа (PNG) с нуля. Используйте любой из них, который Вам более понятен:

  1. Используя DocumentBuilder.

  2. Используя DOM (Объектная Модель Документа) напрямую.

Способ 1: Создание нового документа с помощью DocumentBuilder

DocumentBuilder — это мощный класс, связанный с DocumentCore и позволяющий динамически создавать документы с нуля или добавлять новые элементы в существующий документ.

Все, что возможно с DocumentBuilder, возможно и при непосредственном использовании классов DOM (Объектная Модель Документа), но обычно требует больше строк кода, чем при использовании DocumentBuilder.

        public static void CreateImageUsingDocumentBuilder()
        {
            // Set a path to our document.
            string docPath = @"Result-DocumentBuilder.png";

            // Create a new document and DocumentBuilder.
            DocumentCore dc = new DocumentCore();
            DocumentBuilder db = new DocumentBuilder(dc);

            // Set page size A4.
            Section section = db.Document.Sections[0];
            section.PageSetup.PaperType = PaperType.A4;

            // Add 1st paragraph with formatted text.
            db.CharacterFormat.FontName = "Verdana";
            db.CharacterFormat.Size = 16;
            db.CharacterFormat.FontColor = SautinSoft.Document.Color.Orange;
            db.Write("This is a first line in 1st paragraph!");
            // Add a line break into the 1st paragraph.
            db.InsertSpecialCharacter(SpecialCharacterType.LineBreak);
            // Add 2nd line to the 1st paragraph, create 2nd paragraph.
            db.Writeln("Let's type a second line.");
            // Specify the paragraph alignment.
            (section.Blocks[0] as Paragraph).ParagraphFormat.Alignment = HorizontalAlignment.Center;

            // Add text into the 2nd paragraph.
            db.CharacterFormat.ClearFormatting();
            db.CharacterFormat.Size = 25;
            db.CharacterFormat.FontColor = SautinSoft.Document.Color.Blue;
            db.CharacterFormat.Bold = true;
            db.Write("This is a first line in 2nd paragraph.");
            // Insert a line break into the 2nd paragraph.
            db.InsertSpecialCharacter(SpecialCharacterType.LineBreak);
            // Insert 2nd line with own formatting to the 2nd paragraph.
            db.CharacterFormat.Size = 20;
            db.CharacterFormat.FontColor = SautinSoft.Document.Color.DarkGreen;
            db.CharacterFormat.UnderlineStyle = UnderlineType.Single;
            db.CharacterFormat.Bold = false;
            db.Write("This is a second line.");

            // Add a graphics figure into the paragraph.
            db.CharacterFormat.ClearFormatting();
            Shape shape = db.InsertShape(SautinSoft.Document.Drawing.Figure.SmileyFace, new SautinSoft.Document.Drawing.Size(50, 50, LengthUnit.Millimeter));
            // Specify outline and fill.
            shape.Outline.Fill.SetSolid(new SautinSoft.Document.Color("#358CCB"));
            shape.Outline.Width = 3;
            shape.Fill.SetSolid(SautinSoft.Document.Color.Orange);            

            // Save the 1st document page to the file in PNG format.
            Bitmap page = dc.GetPaginator().Pages[0].Rasterize(300, SautinSoft.Document.Color.White);
            page.Save(docPath);

            // Open the result for demonstration purposes.
            System.Diagnostics.Process.Start(new System.Diagnostics.ProcessStartInfo(docPath) { UseShellExecute = true });
        }

Способ 2: создание нового документа используя DOM

DOM (объектная модель документа) очень проста и понятна, это представление документа Word в памяти. 

        public static void CreateImageUsingDOM()
        {
            // Set a path to our document.
            string docPath = @"Result-DocumentCore.png";

            // Create a new document.
            DocumentCore dc = new DocumentCore();

            // Add new section.
            Section section = new Section(dc);
            dc.Sections.Add(section);

            // Let's set page size A4.
            section.PageSetup.PaperType = PaperType.A4;

            // Add two paragraphs            
            Paragraph par1 = new Paragraph(dc);
            par1.ParagraphFormat.Alignment = HorizontalAlignment.Center;
            section.Blocks.Add(par1);

            // Let's create a characterformat for text in the 1st paragraph.
            CharacterFormat cf = new CharacterFormat() { FontName = "Verdana", Size = 16, FontColor = SautinSoft.Document.Color.Orange };
            Run run1 = new Run(dc, "This is a first line in 1st paragraph!");
            run1.CharacterFormat = cf;
            par1.Inlines.Add(run1);

            // Let's add a line break into the 1st paragraph.
            par1.Inlines.Add(new SpecialCharacter(dc, SpecialCharacterType.LineBreak));
            // Copy the formatting.
            Run run2 = run1.Clone();
            run2.Text = "Let's type a second line.";
            par1.Inlines.Add(run2);

            // Add 2nd paragraph.
            Paragraph par2 = new Paragraph(dc, new Run(dc, "This is a first line in 2nd paragraph.", new CharacterFormat() { Size = 25, FontColor = SautinSoft.Document.Color.Blue, Bold = true }));
            section.Blocks.Add(par2);
            SpecialCharacter lBr = new SpecialCharacter(dc, SpecialCharacterType.LineBreak);
            par2.Inlines.Add(lBr);
            Run run3 = new Run(dc, "This is a second line.", new CharacterFormat() { Size = 20, FontColor = SautinSoft.Document.Color.DarkGreen, UnderlineStyle = UnderlineType.Single });
            par2.Inlines.Add(run3);

            // Add a graphics figure into the paragraph.
            Shape shape = new Shape(dc, new InlineLayout(new SautinSoft.Document.Drawing.Size(50, 50, LengthUnit.Millimeter)));
            // Specify outline and fill.
            shape.Outline.Fill.SetSolid(new  SautinSoft.Document.Color("#358CCB"));
            shape.Outline.Width = 3;
            shape.Fill.SetSolid(SautinSoft.Document.Color.Orange);            
            shape.Geometry.SetPreset(Figure.SmileyFace);
            par2.Inlines.Add(shape);

            // Save the 1st document page to the file in PNG format.
            Bitmap page = dc.GetPaginator().Pages[0].Rasterize(300, SautinSoft.Document.Color.White);
            page.Save(docPath);

            // Open the result for demonstration purposes.
            System.Diagnostics.Process.Start(new System.Diagnostics.ProcessStartInfo(docPath) {UseShellExecute=true});
        }

Как видите, в методе Rasterize() мы указали DPI и цвет в качестве параметров. Смотрите другие примеры Сохранить документ как изображение.
