Type & code
Barcode
Rows turn into barcode: bar widths snap to whole modules.
Controls
- module
- Width of one module — the x-dimension a real code measures everything in. A bar is always a whole number of them
- symbol
- How many modules make one symbol. EAN uses seven, Code 128 eleven; the number sets the rhythm of the code
- band
- Height of one band. Each band is its own code — the picture is read row by row
- guard
- How far the guard bars stick out. At zero they vanish and the band becomes a plain line screen — they are what makes it read as a barcode
- contrast
- A number from -1 to 1, 0 by default.
- ink
- A colour, #111111 by default.
- paper
- A colour, #f4f2ec by default.
