microbuffer

Build Status NPM version

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

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()
