Release Notes

2026.8 - August, 2026
We'll describe in more detail what's been fixed/improved and why you should update:

1. The document page count engine has been improved.
A document format that doesn't have pages is called a flow-based or reflowable document. Its content flows continuously instead of being divided into fixed pages. Examples include:

Plain Text (.txt).
HTML (.html) (web pages).
Markdown (.md).
XML (.xml).
EPUB (reflowable e-books).

In contrast, page-based document formats include:

Microsoft Word (.docx, .rtf, .doc) (uses pages in Print Layout).
PDF (.pdf any versions).
OpenDocument Text (.odt).

If we’re talking about Document .Net is specifically about Microsoft Word Formats (DOC, DOCX, RTF), the document itself always supports pages in Print Layout. However, if you switch to Web Layout or Draft view, the document is displayed as a continuous flow without visible page boundaries, even though the document still has pages for printing. The same is in PDF .Net (PDF files).

Sautinsoft.Document determines the page count by laying out the document according to its current formatting and then counting the resulting pages. The total can change as you edit because Word continuously recalculates the layout.

The page count depends on factors such as:

Paper size (e.g., A4 vs. Letter).
Page margins.
Page orientation (Portrait or Landscape).
Font type and size.
Line and paragraph spacing.
Headers and footers.
Images, tables, and other objects.
Section breaks and page breaks.
Columns or other page layout settings.

For example, if you increase the font size from 11 pt to 12 pt, the same text may no longer fit on the same number of pages, increasing the page count.

How to see the page count

Status bar: The bottom-left corner of the Word window usually displays something like "Page 3 of 12".
Print Preview: This shows exactly how the document is paginated for printing.
Word Count dialog: Go to Review → Word Count to see the number of pages along with words, characters, paragraphs, and lines.

Why the page count may differ

The same document can have a different number of pages if:

It is opened on a system with different printer settings (Word uses the active printer's metrics to help determine layout).
The paper size changes (e.g., A4 vs. Letter).
Fonts are missing and substituted.
Margins or scaling settings are modified.
The document is viewed or printed with different layout options.

In short, Sautinsoft’ engine does not estimate pages based on the number of words. It calculates pages from the fully formatted document layout as it would appear when printed or viewed in Print Layout.

Our engine has been improved and now better handles various document formats (DOCX, PDF, DOC, RTF) that do not have a clear understanding of the number of pages. We also added support for the NСalc component inside components for fast and optimal determination of the number of pages.

2. To perform a full-text search in a PDF using C#.

A full-text search in a PDF means searching the actual textual content of a PDF document, rather than just its filename, metadata, or bookmarks. The goal is to find documents (or locations within documents) that contain specific words, phrases, or patterns.

There are several levels of complexity depending on the type of PDF and the search requirements.

Searchable vs. Scanned PDFs

Searchable PDF

Microsoft Word → Save as PDF
Excel → Export to PDF
PDF generated from HTML

Scanned PDF

There is no searchable text.

To perform full-text search, the document must first go through OCR (Optical Character Recognition) to convert the image into text.

How PDF Text Is Stored

A PDF library reconstructs these characters into words and sentences before searching.

Basic Full-Text Search


                            bool found = text.Contains("invoice",
                            StringComparison.OrdinalIgnoreCase);

The methods of SEARCHING in SautinSoft:

Phrase Search
Multiple Keywords
Regular Expression Search
Case Sensitivity
Whole Word Search
Fuzzy Search
Indexed Search
Highlighting Results

Challenges in PDF Full-Text Search

PDFs are designed for presentation, not logical document structure, so searching isn't always straightforward. Common challenges include:

Typical Architecture

Full-Text Search in C#

Open the PDF with a PDF/DOCX SautinSoft library.
Extract text from each page.
If the PDF is scanned, run OCR first.
Search the extracted text using string matching, regular expressions, or an index.
Optionally map matches back to page coordinates to highlight them.

For a few PDFs, extracting text and searching in memory is usually sufficient. For large collections (thousands or millions of documents), building a full-text index with a search engine such as Sautinsoft.Document or SautinSoft.Pdf provides much faster query performance and supports advanced features like relevance ranking, phrase queries, and fuzzy matching.

            }
        }
    }
}

Advantages

Free
.NET Support
Good text extraction
No Adobe dependency

3. Full support for embedded fonts at SautinSoft’ engines.

Embedded fonts in a PDF are font programs that are stored inside the PDF file itself. Instead of relying on the fonts installed on the viewer's computer, the PDF contains the necessary font data, ensuring the document looks the same everywhere.

Why embed fonts?
Embedding fonts provides several benefits:

Consistent appearance – Text is rendered exactly as the author intended.
Cross-platform compatibility – The PDF displays correctly on Windows, macOS, Linux, mobile devices, and browsers.
Reliable printing – Prevents font substitution that can change layout or line breaks.
Long-term archiving – Required by standards such as PDF/A.

Types of font embedding

Full embedding

Advantages

All characters are available.
Text can often be edited without needing the original font.

Disadvantages

Larger PDF file size.

Font subsetting

Advantages

Much smaller PDF.
Most PDFs use this approach.

Disadvantages

If you later edit the PDF and add characters that weren't embedded, the editing software may need access to the original font or substitute another font.

What happens if fonts are not embedded?

When a PDF references a font that isn't embedded:
1) The PDF viewer looks for the font on the local system.
2) If it cannot find it, it substitutes another font.
3) The document's appearance may change.

Different line wrapping
Changed page breaks
Misaligned tables
Incorrect spacing
Missing symbols or non-Latin characters.

Which fonts cannot be embedded?

embedding permission

Installable
Editable
Preview & Print
Restricted (embedding prohibited).

✅ Reads embedded fonts from PDF files.
✅ Preserves embedded fonts during PDF loading and saving.
✅ Supports three modes through PdfLoadOptions.PreserveEmbeddedFonts:

Example:

var options = new PdfLoadOptions()
{
    PreserveEmbeddedFonts = PropertyState.Enabled
};

DocumentCore dc = DocumentCore.Load("input.pdf", options);

✅ Reads DOCX files containing embedded fonts.
✅ Preserves embedded fonts during document processing.
✅ Continual improvements have been made to font subsetting, reducing document size while maintaining rendering quality.

Font Handling

When a required font is unavailable, SautinSoft provides:

Detection of missing fonts (FontSettingsMissingFonts)
Font substitution (FontSettingsAddFontSubstitutes)
Font selection events for custom replacement logic

Unicode and Advanced Font Support

TrueType fonts
Unicode fonts
OpenType ligatures
CJK (Chinese, Japanese, Korean)
WOFF and other font formats
Special glyphs, ornaments, and symbol fonts.

2026.7 - July, 2026
This is the biggest update in a few months (since Jan, 2026). We'll describe in more detail what's been fixed/improved and why you should update:

Image to PDF conversion throws an error if PDFVision.dll is added from GAC.
Content of page does not fit correctly inside page when converting HTML to PDF.
Some text content is missing when converting HTML to PDF.
Component stability in multithreading mode.

The functionality of the components we developed significantly exceeds standard data conversion tasks. Previously, stability degradation in multithreaded modes led to process crashes.

Months of modernization have resulted in optimized single-threaded and multithreaded processing algorithms, as well as improved interaction between PDF, DOCX, HTML, RTF, and Excel interfaces. For parallelization in the C# environment, it is recommended to use Parallel.ForEachAsync when I/O-bound operations are predominant to avoid thread blocking, or Parallel.ForEach for CPU-bound intensive operations.

The proper functioning of all SautinSoft software products is hereby confirmed.
