# This demo allows testing multiple combination of specific font variations.
|
||
|
|
# Two lines will be printed for every entry in "variations[]",
|
||
|
|
# First line showing the entry index and parametes,
|
||
|
|
# Second line being "Hello World".
|
||
|
|
#
|
||
|
|
# Example:
|
||
|
|
# If a printed line shows:
|
||
|
|
# variations[2] =
|
||
|
|
# Hello World
|
||
|
|
# F=b B U AL=R
|
||
|
|
# It is the 3rd entry (zero-based index 2),
|
||
|
|
# with Font="B", Bold, Underline, Align=right.
