Libraries Module

The Libraries module provides generic utility functions for string manipulation and IFF/AIFF file format parsing. These functions cover character replacement and filtering, locale-aware case conversion, and support for reading and unpacking IFF-format data commonly used in Amiga multimedia files.

String Functions

• ChangeChar — Finds and replaces a specific character within a byte sequence.
• FilterChars — Replaces all characters outside a specified ASCII range with a given character.
• StringToUpper — Converts a string to uppercase using the locale system.
• StringToLower — Converts a string to lowercase using the locale system.

IFF/AIFF Functions

• FindAIFFChunk — Searches for a specific chunk within an IFF/AIFF data structure.
• TestAIFFChunk — Validates whether the data at the current position is a valid IFF chunk.
• NextIFFChunk — Advances to the next chunk in an IFF data structure.
• UnPackerILBMBODY — Unpacks an ILBM BODY chunk into bitplane data, supporting up to 8 bitplanes.
• UnPackerILBMCMAP — Unpacks an ILBM CMAP chunk into a color table.
