Class PdfPage
- Namespace
- PDiffy
- Assembly
- PDiffy.dll
A page. Unreadable is set when the PDF library could not load it; its other values are then empty. The boxes are set only when the page declares them (or, for the crop box, inherits one).

Properties
ArtBox
The area of the page's meaningful content; null when the page doesn't set one.
public PdfBox? ArtBox { get; init; }Property Value
ArtifactsHoldingTaggedContent
How many artifacts on the page hold tagged content (marked content with an MCID), which PDF/UA doesn't allow.
public int ArtifactsHoldingTaggedContent { get; init; }Property Value
ArtifactsInTaggedContent
How many artifacts on the page sit inside tagged content, which PDF/UA doesn't allow, since a screen reader can't tell whether to read them.
public int ArtifactsInTaggedContent { get; init; }Property Value
BleedBox
The area to keep when printing with bleed; null when the page doesn't set one.
public PdfBox? BleedBox { get; init; }Property Value
CropBox
The area a viewer shows; null when neither the page nor a parent sets one, so all of it shows.
public PdfBox? CropBox { get; init; }Property Value
DefaultColors
A hash of the page's default color spaces (its /DefaultGray, /DefaultRGB and /DefaultCMYK resources), and of those each form it draws sets for its own content, such as "3f9c0a1b2d4e5f60", or "unreadable". They change how gray, RGB and CMYK colors show, often through a color profile. Null when neither the page nor its forms set any.
public string? DefaultColors { get; init; }Property Value
Group
The page's transparency group, which changes how overlapping content blends.
public PdfPageGroup? Group { get; init; }Property Value
HasAnnotations
Whether the page has annotations, such as links or form fields.
public required bool HasAnnotations { get; init; }Property Value
Height
The media box's height in points, before Rotation turns the page; 0 for an unreadable page.
public required double Height { get; init; }Property Value
Number
The page number, counted from 1.
public required int Number { get; init; }Property Value
RepeatedMcids
How many marked-content sequences on the page reuse an MCID from an earlier sequence in the same content stream, as when a form XObject with MCIDs is drawn more than once. PDF/UA allows each MCID only once per content stream, since the parent tree can give it to only one element.
public int RepeatedMcids { get; init; }Property Value
Rotation
How far a viewer turns the page clockwise, in degrees: 0, 90, 180 or 270.
public required int Rotation { get; init; }Property Value
Tabs
The tab order of the page's links and form fields: "R" (rows), "C" (columns) or "S" (structure order, which PDF/UA requires on a page with annotations), or another name the PDF writes; null when the page doesn't set one. PdfTabOrders lists the standard ones.
public required string? Tabs { get; init; }Property Value
TrimBox
The finished page after trimming; null when the page doesn't set one.
public PdfBox? TrimBox { get; init; }Property Value
Unreadable
Whether the PDF library couldn't load the page.
public bool Unreadable { get; init; }Property Value
UnreadableHash
For a page that couldn't be loaded, a hash of the entries that decide how it draws, such as its content streams, page boxes and resources, and everything they reach, so a change to the page still shows; null for a page that loaded.
public string? UnreadableHash { get; init; }Property Value
UserUnit
The size of one unit in points, for pages larger than PDF's usual limit; null when the page doesn't set it, which means 1.
public double? UserUnit { get; init; }Property Value
Width
The media box's width in points, before Rotation turns the page, so a portrait page turned 90 degrees still has its portrait width; 0 for an unreadable page.
public required double Width { get; init; }
