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.
