IPageRange

IPageRange is the read-only contract for a page selection, implemented by PageRange. It exposes the boundary values plus three computed classification flags that distinguish an "all pages" selection from a partial or single-page one, which PdfClientService.ExtractPageRanges relies on to decide how to copy pages. (BR-14)

Purpose

• Defines the read surface a page selection must expose for page-extraction logic to classify and act on it.

Context

• Namespace: PdfAPI.Core
• Assembly/package: PdfAPI.Core

Public members

Member	Signature	Purpose
StartPage	int StartPage { get; }	The first page (1-based) included in the selection.
StopPage	int StopPage { get; }	The last page included in the selection; -1 denotes open-ended (through the last page). (BR-15)
IsPartial	bool IsPartial { get; }	Indicates the selection covers a subset of pages rather than the whole document.
IsOriginal	bool IsOriginal { get; }	Indicates the selection spans the entire original document (1 to -1). (BR-14)
IsSingle	bool IsSingle { get; }	Indicates the selection covers exactly one page.

Behavioral notes

• PdfClientService.ExtractPageRanges branches on IsOriginal versus the relative order of StartPage/StopPage to decide whether to copy the whole document, copy ascending, or copy descending. (BR-14, BR-15, BR-16)

Constraints and usage notes

• PageRange is the only implementation shipped in the compiled assembly.*
