Outline of Functions
Reference
Images for registering as image data can be created using the NT-series Sup-
port Tool's image data creation functionality. It is also possible to download files
created using commercial image creation software and use them as image
data for the NT30/30C.
Image data for up to 224 images can be registered on a screen data file using
2-byte codes from FE20 to FEFF. The number of images that can actually be
registered will depend on the status of the image data memory.
Basically, image data can be displayed in any position on the screen, however,
the entire image may not be displayed in some specific positions.
S Library Data
Library data is image data consisting of multiple characters and graphics in
units of 1 x 1 dot ranging from 1 x 1 to 320 x 240 dots (entire screen).
The creation of library data starts by laying out characters and graphics with
attributes on the screen in the same manner as normal screen data.
Next, specify the area to be registered. Only characters and graphics can be
extracted from other screen data and registered as library data. Library data
cannot be registered as displayed elements.
Once registered as library data, complicated images composed of characters
and graphics can be displayed many times easily, and need not be created
again. The image data memory be used more efficiently by using library data.
Library data for up to 896 images can be registered on a screen data file using
2-byte codes FA20 to FAFF, FB20 to FBFF, FC20 to FCFF, and FD20 to FDFF.
Basically, library data can be displayed in any position on the screen. But, in a
position where the entire library data cannot be displayed, it automatically
moves to another position. Use care in setting a display position.
Difference between Image Data and Library Data
While image data can take any form as shown in the screen example, only
images consisting of characters and graphics can be library data.
Because only characters and graphic information are registered as library data,
library data requires less memory capacity than image data, for which all the
dots to be displayed on the screen must be registered.
Image data cannot be reversed or flashed, whereas library data can be reversed
or flashed according to the settings for the elements when they are registered.
Library data
Even complicated
data can be
displayed.
