If the data amount per raster line is not a multiple of 8 bits, the window is raised to a multiple of 8 bits.
b.Pixel size data: (DATA TYPE CODE = X©80)
This scanner calculates the numbers of X>direction pixels and Y>direction pixels of the image data to be transferred to the initiator. The scanner performs this calculation by referencing the resolution and area set up with the SET WINDOW command. This data need not be issued if the numbers of pixels are known by the initiator.
The transfer format for this data is shown in the following illustration.
