// A 0.33 mm module (the X dimension) in points, with the text under the bars and 0.05 mm taken off each bar
// for ink spread. The quiet zone's top-left corner goes at (36, 36).
float module = 0.33f / 25.4f * 72;
page.DrawBarcode(code, new Vector2(36, 36), module, Rgba8.Black, new BarcodeDrawOptions
{
    Font = font,
    BarWidthReduction = 0.05f / 25.4f * 72,
});

Properties

BarWidthReduction

Gets how much narrower each dark bar or module is drawn, in output units (pixels for ToRaster(int, BarcodeDrawOptions?)), to make up for ink spreading on a printer; 0 by default. Half is taken off each side. 2D modules shrink in height too. It changes drawing only, never the modules.

public float BarWidthReduction { get; init; }

Property Value

float

Exceptions

ArgumentOutOfRangeException

The value is negative or not finite.

Default

Gets the defaults: quiet zone on, no bar width reduction, no text.

public static BarcodeDrawOptions Default { get; }

Property Value

BarcodeDrawOptions

Font

Gets the font for the human-readable text under the bars (HumanReadableText), or null, the default, to draw no text. Its size is in output units. ToPath(float, BarcodeDrawOptions?) draws no text.

public Font? Font { get; init; }

Property Value

Font?

QuietZone

Gets a value indicating whether the symbol's quiet zone (QuietZone) is kept clear around it; true by default. Readers need it; turn it off only when the space around the symbol is blank anyway. Linear symbols have it at the left and right only.

public bool QuietZone { get; init; }

Property Value

bool
