@ -2561,11 +2561,17 @@ DotCode uses a grid of dots in a rectangular formation to encode characters up
to a maximum of approximately 450 characters (or 900 numeric digits). The
symbology supports ECI encoding and GS1 data encoding. By default Zint will
produce a symbol which is approximately square, however the width of the symbol
can be adjusted by using the --cols= option or by setting option_2. Outputting
DotCode to raster images (PNG, GIF, BMP, PCX) will require setting the scale of
the image to a larger value than the default (e.g. approx 10) for the dots to
be plotted correctly. Approximately 33% of the resulting symbol is comprised of
error correction codewords.
can be adjusted by using the --cols= option or by setting option_2 (maximum
108). Outputting DotCode to raster images (PNG, GIF, BMP, PCX) will require
setting the scale of the image to a larger value than the default (e.g. approx
10) for the dots to be plotted correctly. Approximately 33% of the resulting
symbol is comprised of error correction codewords.
DotCode has two sets of 4 masks, designated 0-3 and 0'-3', the second "prime"
set being the same as the first with corners lit. The best mask to use is
selected automatically by Zint but may be manually specified by using the
--mask= switch with values 0-7, where 4-7 denote 0'-3', or by setting option_3
to (N + 1) << 8 where N is 0-7.
