Independent publishers document local PDF page-counting and page-box workflows on July 29, 2026

What the sources reported

wowmoron.blogspot.com leans on AcroExch.GetNumPages for local VBA page iteration

The post "Get text data from pdf to excel range using acrobat library in VBA" walks through opening a PDF on disk via CreateObject("AcroExch.App") and CreateObject("AcroExch.AVDoc"), then iterating with `For i = 0 To pdf_doc.GetNumPages - 1` and acquiring each page through `pdf_doc.AcquirePage(i)`. The same blog publishes companion posts for reading form fields with the AFormAutLib reference and deleting pages via `todoc.DeletePages(0, 1)`, all operating on a hard-coded file path such as `C:\Users\allso\Desktop\Business Loan Application Form.pdf` and saving with `PDSaveFull`. The working pattern is local-only: the file is opened by path, processed in place, and saved back, never uploaded.

abapsamples.blogspot.com documents a SAPScript total-pages display bug at 16 pages

A SAPScript post titled "SAPScript: Total number of pages display problem" reports that with `&PAGE& OF &SAPSCRIPT-FORMPAGES(C)&`, the total-pages variable misbehaves once a form exceeds 10 pages. On a 16-page output the post shows pages 1 to 9 displaying "Page : 1 of 1" through "Page : 9 of 1", and pages 10 onward correcting themselves to "Page : 10 of 16" through "Page : 16 of 16". The author's fixes are either specifying an explicit length with `&SAPSCRIPT-FORMPAGES(3)&` or dropping the (C) compression option. The piece matters for anyone reproducing page totals inside generated PDFs without re-rendering the document.

dev.to introduces PDF Engine — Rust/WASM PDF processing in the browser

The dev.to post "PDF Engine — Rust/WASM PDF Processing in Your Browser" describes a Rust-and-WebAssembly pipeline that handles PDF work on the client side rather than uploading to a server. It is positioned for users who want to count, extract, or transform PDF content without leaving the browser tab, matching the no-upload constraint many practitioners carry when handling documents on a single workstation.

dev.to flags merged-cell breakage for multi-column PDF table extraction

Hannune's dev.to post "Why merged cells break table extraction from multi-column PDFs" argues that merged cells are a structural failure point for automated table extraction, with the cell-spanning logic defeating row-and-column heuristics. The takeaway for page-dimension work is that counting pages is only one step; downstream grouping by MediaBox often has to account for content that defies rigid row boundaries, so any local page-counter output needs to be paired with a structural pass.

Prospect Park Alliance publishes a tool-agnostic two-PDF comparison methodology

The couchdb.prospectpark.org guide "Compare Two Pdfs A Step By Step Guide" presents a workflow for diffing two PDFs across text, structure, and metadata, aimed at legal, technical, and compliance reviewers. It explicitly avoids recommending a single vendor and treats the comparison as a structured inspection of the file rather than a side-by-side eyeball check — a useful framing for practitioners who want to reason about page boxes without altering the document.

Red Hat Developer warns that single-threaded CPU parsing stalls large-PDF RAG pipelines

The Red Hat Developer article "Build a distributed RAG pipeline with Ray Data on OpenShift AI" notes that most RAG tutorials parse a handful of documents, but scaling to thousands of PDF files with tables and multi-column formatting exposes a bottleneck: GPUs sit idle while a single-threaded CPU parser slowly grinds through the corpus. The author frames distributed parsing as the remedy. For practitioners measuring page boxes across large PDFs, this translates into a workload that cannot rely on a quick in-process counter run on the main thread.

GlobalSecurityMag carries a PyPDF2 memory-leak advisory dated April 23, 2026

The vigilance.fr bulletin republished at globalsecuritymag.com, "Vigilance.fr - Python PyPDF2: memory leak dated 23/04/2026," records that an attacker can craft input that triggers a memory leak in Python PyPDF2, with denial of service as the outcome. The advisory is relevant to any locally hosted PyPDF2-based page counter because the library is a common choice for offline page and MediaBox reads — practitioners handling untrusted PDFs should isolate the parser rather than expose it to the network.

    Counting pages is the easy step. The harder call is what gets attached to each page number so a downstream system can act on it without re-opening the file. The April 23, 2026 PyPDF2 memory-leak advisory is the reason a 14-day test on copyable span links needs to run inside a sandboxed parser from day one, not retrofitted after a clean benchmark. I would rather spend the first week watching one production-shaped PDF corpus under the new duplicate_write flag than ship a hardened schema we cannot unwind. Owners, kill condition, and the exact success metric need to be on paper before the test starts, or it is just a longer meeting. Worth a look for the local-only framing: /insights/pdf/

    Frontend performance is the angle nobody is putting on this. A duplicate_write flag is fine, but copyable span links keyed to page, field, and hash are still rendered client-side, and if that render hits the main thread on a low-end device it will show up as INP regression long before anyone notices the evidence spans are correct. The Red Hat piece about single-threaded CPU parsing stalling large-PDF pipelines makes the same point from the server side: budgeted chunking, not a bigger library. I'd want the 14-day test instrumented for time-to-interactive on the worst device in the fleet, with the duplicate_write path offloaded to a worker, before anyone calls the schema hardened. Local framing worth checking: /insights/pdf/
