IDOL 23.2.2

# KeyView Viewing SDK

## 23.2.0

### New in this Release

- KeyView format detection has been extended, with support for 56 additional file formats. By identifying a larger range of formats present in the enterprise, decisions can be made on how to route, filter, or alert on such documents. For the full list, refer to the KeyView Viewing SDK Programming Guide.

- KeyView has been simplified so that it is much easier to map file formats to readers. File formats no longer have an associated "category". The KeyView configuration files such as `formats.ini`, `formats_e.ini`, and `kvsdk.ini` now identify file formats using the same file format numbers that are returned by format detection.

- KeyView can now extract all platform-specific embedded files from `PDF_Fmt` documents.

- KeyView can now process certain OpenOffice Text files that it would previously reject, and it can process image alt text in OpenOffice Text as hidden text.

- KeyView now supports TIFF (`TIFF_Fmt`) files that use WebP compression.

- Handling of Arabic diacritics (tashkil) has been significantly improved when using the pdfsr reader to process PDFs.

- Text ordering has been improved when using the pdfsr reader to process PDFs.

- The FreeType third-party library has been upgraded to version 2.12.1.

- The ODA third-party library has been upgraded to version 2023.12.

- The zlib third-party library has been upgraded to version 1.2.13.

- The libxml2 third-party library has been upgraded to version 2.10.3.

- The expat third-party library has been upgraded to version 2.5.0.

- The ICU third-party library has been upgraded to version 72.1.

- The openssl third-party library has been upgraded to version 3.0.8.

- The libde265 third-party library has been upgraded to version 1.0.11.

- The XMP-Toolkit third-party library has been upgraded to version 2022.06.

- The wavpack third-party library has been upgraded to version 5.6.0.

- The sqlite third-party library has been upgraded to version 3.41.0.

### Resolved Issues

- (Security update) The third-party libtiff library has been upgraded to version 4.5.0 to resolve known vulnerabilities, including CVE-2022-2056, CVE-2022-2057, CVE-2022-2058, CVE-2022-3452, CVE-2022-3570, CVE-2022-3597, CVE-2022-3598, CVE-2022-3599, CVE-2022-3626, and CVE-2022-3627.

- (Security update) The third-party protobuf library has been upgraded to version 3.21.12 to resolve known vulnerabilities, including CVE-2022-1941.

- (Security update) The libjpeg third-party library has been upgraded to version 9e to resolve potential vulnerabilities.

- KeyView could truncate long sections of text in `PDF_Fmt` documents.

- KeyView did not retrieve the Image Width, Image Height and Bits Per Pixel in summary information from Tagged Image File Format (TIFF) `TIFF_Fmt` files.

- KeyView did not view TIFF documents with images in multiple colourspaces correctly.

- For some Microsft Excel (XLSX) files with a lot of cells using Rich Data Types, KeyView output the names of those types incorrectly, using a number instead of a type name.

- In Word Processor formats such as Microsoft Word (DOCX), embedded images with text wrapping around them were sometimes rendered above the text, obstructing it. To avoid this, ViewingSDK now places images at the start of paragraphs to ensure that the text is readable, making the output more consistent with HTML Export.

- KeyView could skip some user defined properties in summary information for some OLE-based files like `MS_Project_2007_Fmt`.

- When using the pdfsr reader for text in right-to-left languages, diacritic characters were sometimes not extracted correctly.

- Some PDF files took longer to process in version 12.13.0 of the SDK than in version 12.12.0.

- KeyView could exit unexpectedly when processing some Microsoft Visio (.vsd) files.

- KeyView missed text from some Microsoft Visio (.vsd) files.

- Some base-64 encoded attachments to ICS files were extracted incorrectly.

- KeyView could report duplicate metadata from Tagged Image File Format (TIFF) files with multiple pages.

- KeyView could output incorrect metadata names for some PDF files.

- KeyView could omit metadata entries for some PDF files.

- When using the pdfsr reader to process PDFs that contained right-to-left (RTL) text, some text at the top of the file was not included in the output.

- KeyView could process some CSV files incorrectly, meaning fields were output in the wrong columns.

- The reader `kpPDF2rdr` was not thread-safe.
- The reader `kpPDF2rdr` failed to release memory each time a file was processed.
- The reader `kpPDF2rdr` could output incorrect values for page width and height.
