Parent Topic: IMAGE COMMANDS
IL [n1,n2,n3,n4,n5,label]
n1: Image plane to label <last image>
n2: Character font size <1>
-1: small font (6 x 8)
0 or 1: standard font (9 x 12)
2,3,4,5: large font (14*(n2-1) x 24*(n2-1))
n3: Grey-level value of label <255>
n4,n5: Upper left position of label <cursor position>
label: Alphanumeric text for label <prompted>
The standard (default) character font is 9 by 12 pixels. It is
printed when n2 = 0 or 1. The small character font is 6 by 8 pixels
and is printed when n2 = -1. The large font is 14*(n2-1) by
24*(n2-1) pixels, where n2 is between 2 and 5. For example: setting
n2 = 2 prints 14 by 24 pixel large font. If n3 > 0, the characters
are assigned value n3 (default 255). If n3 < 0, the rectangular
border around the characters is assigned the value -n3, whereas
image values under characters are untouched. If `label' is missing,
the user is continuously prompted to enter lines of text until an
empty line is entered. If n4,n5 are not specified, the current
cursor position specifies the upper left corner for the next line of
text. If the cursor is not moved between entering lines of text, the
next line is printed immediately below the current line. However, if
the cursor is moved, the next line is printed starting at the new
cursor position. If both n4,n5 are specified, the cursor position
has no effect on the label position, and each line of text is always
printed below the previous line.
