Every layer starts with the basics. Here we have the layer dimensions, the number of color channels for the image data, and information about the color channels. | parsePositionAndChannels: ->
@top = @file.readInt()
@left = @file.readInt()
@bottom = @file.readInt()
@right = @file.readInt()
@channels = @file.readShort()
@rows = @height = @bottom - @top
@cols = @width = @right - @left |
Every color channel has both an ID and a length. The ID correlates to the color channel, e.g. 0 = R, 1 = G, 2 = B, -1 = A, and the length is the size of the data. | for i in [0...@channels]
id = @file.readShort()
length = @file.readInt()
@channelsInfo.push id: id, length: length
