veraPDF v1.22.0-RC

Version 1.22 RC (August 9, 2022)

Applications

• added HTML and JSON report formats in the CLI app
• fixed CLI scripts for Windows to support arbitrary characters in the veraPDF installation folder
• fixed file drag&drop functionality for the GUI app on macOS
• force MRR report format if policy checks are enabled

• fixed check for veraPDF updates from the GUI app

PDF Model

• added support for evaluating PDF functions
• added support for PDF 2.0 namespace mechanism
• added support for standard structure types in PDF 2.0 namespace

PDF Parser

• improved CFF font parsing: trim the CharSet range by the number of glyphs specified in the other font data
• implemented greenfield parser for PKCS #7 files
• added support for custom font matrices in CFF fonts
• implemented more tolerant Flate decode with broken checksum
• added warning for UTF16-LE encoded text string

Validation

• (PDF/UA-1) added a new rule that the Form structure element without a Role attribute shall have only one child: an object
  reference identifying the widget (ISO 32000-1, Table 348)
• (PDF/A-4) updated supplement numbers for predefined character collections and CMaps
• (PDF/A-2,3,4) added a check if a character in a symbolic TrueType font cannot be mapped to a font glyph via the specified algorithms
• (PDF/A-2,3,4) do not require the presence of a CIDtoGID map for CIDType2 fonts without an embedded font program, which are used solely in rendering mode 3
• revised error messages with additional context parameters

Corpus

• automated regression tests

Core library

• added support for Java 17
• added support for Java Platform Module System (JPMS)

CAUTION: the JPMS support required moving several classes into different packages:

• org.verapdf.pdfa.PdfBoxFoundry -> org.verapdf.pdfbox.foundry.PdfBoxFoundry
• org.verapdf.pdfa.PdfBoxFoundryProvider -> org.verapdf.pdfbox.foundry.PdfBoxFoundryProvider
• org.verapdf.pdfa.VeraFoundry -> org.verapdf.gf.foundry.VeraFoundry
• org.verapdf.pdfa.VeraGreenfieldFoundryProvider -> org.verapdf.gf.foundry/VeraGreenfieldFoundryProvider

These changes need to be applied to any Java source code that integrates veraPDF API as a Java library.
