[Relationship with Other Elements]
S Difference between image data and library data
Image data can take any form for it is composed of dots, but library data can only
be created by assembling fixed display text and graphics.
Since only drawing information for characters and graphics is registered for li-
brary data, library data requires little memory area in comparison with image
data, which requires all the dots to be displayed on the screen to be registered as
data.
Another difference is that “flash” and “inverse” display are not possible for image
data, but library data can be displayed in these modes in accordance with the
display attributes of the registered elements. The timing of the flashing is the
same for all elements.
S It is possible to specify different image/library data for the graphic displayed
when a lamp (image/library lamp) is ON and OFF (page 326).
