Class PdfPageModel

Represents the document object model (DOM) for a single PDF page. Provides access to text, image, and path objects for content analysis and extraction.

This class exposes the internal structure of a PDF page, allowing programmatic access to individual content elements. Use for content extraction, analysis, or understanding page composition.

Example - Analyze page content:

var pdf = PdfDocument.FromFile("document.pdf");
var pageModel = pdf.Pages[0].GetPageModel();

// Count content elements:
Console.WriteLine($"Images: {pageModel.ImageObjects.Count}");
Console.WriteLine($"Text blocks: {pageModel.TextObjects.Count}");
Console.WriteLine($"Paths/shapes: {pageModel.PathObjects.Count}");


// Get page dimensions:
var bounds = pageModel.BoundingBox;
Console.WriteLine($"Page size: {bounds.Width} x {bounds.Height} points");


// Export to JSON:
string json = pageModel.ToJson();

Properties

BoundingBox

Declaration
public RectangleF BoundingBox { get; set; }
Property Value
Type Description
System.Drawing.RectangleF

ImageObjects

Gets the collection of embedded images on this page. Each image includes position, dimensions, and raw image data.

Example - Extract all images:

foreach (var img in pageModel.ImageObjects)
{
    Console.WriteLine($"Image at ({img.BoundingBox.X}, {img.BoundingBox.Y})");
    Console.WriteLine($"Size: {img.BoundingBox.Width} x {img.BoundingBox.Height}");
}

Declaration
public ImageObjectCollection ImageObjects { get; }
Property Value
Type Description
ImageObjectCollection

Collection of ImageObject instances on this page.

PageIndex

Declaration
public uint PageIndex { get; }
Property Value
Type Description
System.UInt32

PathObjects

Gets the collection of vector path objects (shapes, lines, curves) on this page. Includes rectangles, lines, bezier curves, and complex vector graphics.

Example - Analyze shapes:

foreach (var path in pageModel.PathObjects)
{
    var box = path.BoundingBox;
    Console.WriteLine($"Shape at ({box.X}, {box.Y}), size: {box.Width} x {box.Height}");
}

Declaration
public PathObjectCollection PathObjects { get; }
Property Value
Type Description
PathObjectCollection

Collection of PathObject instances representing vector graphics.
Remarks

Path objects include borders, lines, shapes, and decorative elements. They are defined using PDF path operators (moveto, lineto, curveto, etc.).

TextObjects

Gets the collection of text objects (characters, words, text runs) on this page. Provides granular access to text content with position, font, and style information.

Example - Extract text with positions:

foreach (var text in pageModel.TextObjects)
{
    Console.WriteLine($"Text: '{text.Text}'");
    Console.WriteLine($"Position: ({text.BoundingBox.X}, {text.BoundingBox.Y})");
    Console.WriteLine($"Font: {text.FontName}, Size: {text.FontSize}");
}

Declaration
public TextObjectCollection TextObjects { get; }
Property Value
Type Description
TextObjectCollection

Collection of TextObject instances with text content and metadata.
Remarks

For simpler text extraction without position data, use ExtractAllText(TextExtractionOrder) or ExtractTextFromPage(Int32).
