# This is an example of using complex datatypes.

# It is not recommended to use directly.

# To use a similar datastruct please define a custom message with appropriate semantic meaning.

# The multiarray declares a generic multi-dimensional array of a

# particular data type. Dimensions are ordered from outer most

# to inner most.

# Accessors should ALWAYS be written in terms of dimension stride

# and specified outer-most dimension first.

# multiarray(i,j,k) = data[data_offset + dim_stride[1]*i + dim_stride[2]*j + k]

# A standard, 3-channel 640x480 image with interleaved color channels

# would be specified as:

# dim[0].label = "height"

# dim[0].size = 480

# dim[0].stride = 3*640*480 = 921600 (note dim[0] stride is just size of image)

# dim[1].label = "width"

# dim[1].size = 640

# dim[1].stride = 3*640 = 1920

# dim[2].label = "channel"

# dim[2].size = 3

# dim[2].stride = 3

# multiarray(i,j,k) refers to the ith row, jth column, and kth channel.

#MultiArrayDimension[] dim # Array of dimension properties

#uint32 data_offset # padding bytes at front of data
