* Settings of template selection, number of pixels per line, selection of scale-up/scale-down and
typical prediction function must meet the settings at time of stripe coding/decoding to be carried
out after this.
[Performs loading/storing process during this period.]

Notes: 1. For ON/OFF bit of TP function in the image data processing,
the ON/OFF bit of the TP function just before coding/decoding
shall be kept.
2.In the image data load/store processing, be sure to set the
number of transfer lines to "2".
(The 1st line is data on the line (final line – 1) of the stripe.
The 2nd line is data on the last line of stripe.)
When a line stripe is adopted for the first stripe of the page in
the image data store processing, and read out line of the first
line is outside data of stripe, the all white data must used for
replacement or the image data load function must be used in
advance to clear line memory.
