OpenJPEG Interface Layer

Overview

HotPDF includes the OpenJPEG 2.5 binding in the HPDFOpenJpeg.pas unit. The binding is used by HPDFJpeg2000.pas to decode JPEG 2000 files and JPXDecode image streams into bitmap samples for normal HotPDF image workflows

What Is Included

• OpenJPEG-related record and constant declarations
• Codec identifiers for J2K, JPT, and JP2 workflows
• Memory-stream callbacks used by the JPEG2000 decoder
• Static-link compatibility helpers required by the bundled OpenJPEG object set

Current Scope

• Default HotPDF builds include the bundled OpenJPEG-backed JPEG2000 decoder
• JPEG2000 import support is documented separately in JPEG2000 Support
• The interface layer is internal infrastructure for JPXDecode and JPEG 2000 file import paths
