Shading
Shading (also sometimes referred to as hatching) allows documents to represent damaged/unreadable parts of source texts.
Shading is based on the principle that each quadrat (and glyph) is virtually divided in 4 (rectangular) sub-regions.
These sub-regions inside a virtual quadrat square can be shaded individually to precisely represent the damaged parts of the source texts.
Shading is performed on individual quadrats and individual glyphs with
the \# operator. When used as is (\#), the shading
is done on all 4 sub-regions. Otherwise, you can specify individual
sub-regions that you want to shade by adding their corresponding
number (1 to 4) right after the pound sign (#).
The shading modifier will be applied to the outermost group of glyphs (when parentheses are used) preceeding it.
A1\# ---> shade A1 completely (sub-regions 1, 2, 3 and 4)
A1\#1 ---> shade only top-left sub-region
A1\#12 ---> shade top-left (1) and top-right (2) sub-regions
A1:(X1*X1)\# ---> shade the region occupied by X1*X1 (notice they are
grouped with parentheses)
A1\#13:X1*X1 ---> shade the left-half of the region occupied by A1
(A1:X1*X1)\# ---> shade the whole quadrat
..\# ---> shade a space glyph
..\#:N1 ---> shade the top half of quadrat (space glyph
only will be shaded)
Another shading modifier exists to shade sequences of adjacent quadrats. This
operator is the #b...#e pair and acts on all quadrats
between the code pair.
#b A1:X1*X1 #e ---> shade a single whole quadrat #b C1 G17 G1 #e ---> shade the 3 quadrats C1, G17 and G1 #b .. .. .. #e ---> shade 3 empty spaces quadrats
