• Added asynchrony signature demo with visible appearance.

SetaPDF-Core Component

Feature

• Implemented re-calculation of font bounding box for Type0 fonts with a TrueType font program.
• Added SetaPDF_Core_Font_Type0_Subset class.
• Added ToUnicode creation class.
• Added SetaPDF_Core_Font_TrueType_Subset class.

Change

• Increased default byte length from 1024 to 5500 bytes in which the component will search for the initial "startxref" keyword.
• Introduced SetaPDF_Core_Font_FontInterface and updated all related type hints accordingly.
• Removed getGlyphsWidthByCharCodes() method and internally used property from all font classes.

Bugfix

• Prevent warning if document metadata package is empty.

Tweak

• Ensured encoding object type in simple font class.
• Handle reading of direct objects without a valid PDF value (throw an exception).
• Cache calculated font bounding boxes for TrueType and Type0 fonts.
• Jump to a more logical byte offset if parsing of a cross-reference table fails.
• Removed creation of name objects by string type from SetaPDF_Core_Type_AbstractType::writePdfString().
• Optimized SetaPDF_Core_Encoding::utf16BeToUnicodePoint().
• Ignore invalid range values in CMAP parser.
• Forward document instance in SetaPDF_Core_Type_Dictionary::_handlePdfStringCallback() calls.
• Optimized word (or better space) counting in text graphic state class.
• Optimized exception messages in horizontal metrics table class of the TrueType parser.
• Ignore hybrid cross-references if /XRefStm points to an invalid byte offset.
• Optimized handling of corrupted documents.
• String reader uses PHP streams internally now.
• Refactored PNG file handling through PHP streams instead of strings to reduce memory usage.
• Fixed incorrect return type hints in doc blocks.
• Added support for reading of malformed XMP metadata packages.
• Added "Accept-Ranges: none" header to both HTTP writer classes.
