Light implementation of binary buffer with helpers for easy access.

microbuffer

Light implementation of binary buffer with helpers for easy access.

This library was written for fontello's font convertors - svg2ttf, ttf2woff, ttf2eot. Main features are:

• good speed & compact size (no dependencies)
• transparent typed arrays support in browsers
• methods to simplify binary data read/write

Since the goals of this package are specific, it is not recommended for use in other projects.

API

Constructor

• new MicroBuffer(microbuffer [, offset, length]) - wrap MicroBuffer instanse, sharing the same data.
• new MicroBuffer(Uint8Array|Array [, offset, length]) - wrap Uint8Array|Array.
• new MicroBuffer(size) - create new MicroBuffer of specified size.

Methods

• .getUint8(pos)
• .getUint16(pos, littleEndian)
• .getUint32(pos, littleEndian)
• .setUint8(pos, value)
• .setUint16(pos, value, littleEndian)
• .setUint32(pos, value, littleEndian)

With position update:

• .writeUint8(value)
• .writeInt8(value)
• .writeUint16(value, littleEndian)
• .writeInt16(value, littleEndian)
• .writeUint32(value, littleEndian)
• .writeInt32(value, littleEndian)
• .writeUint64(value)

Other:

• .seek(pos)
• .fill(value)
• .writeBytes(Uint8Array|Array)
• .toString()
• .toArray()
