Enum Class TextSize

java.lang.Object

java.lang.Enum<TextSize>

io.github.chkrishnatej.rp3200.TextSize

All Implemented Interfaces:

Serializable, Comparable<TextSize>, Constable

public enum TextSize
extends Enum<TextSize>

Character magnification (ESC/POS command GS ! n).

A WIDE or DOUBLE character takes two columns, so on 80 mm paper a line holds 24 such characters instead of 48. The builder takes this into account for separators, columns and EscPosBuilder.lineWidth().

Sizes and their template tags

Constant	Width x height	Template tag	Chars per line (80 / 58 mm)
NORMAL	1 x 1	(default)	48 / 32
TALL	1 x 2	[tall]	48 / 32
WIDE	2 x 1	[wide]	24 / 16
DOUBLE	2 x 2	[big]	24 / 16
