How can I get the content of the pattern?

[nieyuyao]

The format of the pattern content is as follows according to the specification.

But i can't get it through the psd.js. This is like because there is no parsing of the Additional Layer Information.

psd.js/lib/psd/layer_mask.coffee

Lines 23 to 38 in 7e8392d

	parse: ->
	maskSize = @file.readInt()
	finish = maskSize + @file.tell()
	return if maskSize <= 0
	@parseLayers()
	@parseGlobalMask()
	# The layers are stored in the reverse order that we would like them. In other
	# words, they're stored bottom to top and we want them top to bottom.
	@layers.reverse()
	@file.seek finish
	parseLayers: ->

Other libraries have this parsing, such as psd.rb.
