Functions ¶

func PtToF ¶

func PtToF(pt Pt) float64

Types ¶

type Dot ¶

type Dot float64

Dot is the measurement used by layla and is defined as 1/8 mm or 1/203 inch. We use the 200 dpi dot as default, because it easier to work with than mm or 300 dpi dots. During layout we round to half dots so we do not lose information relevant for 300 dpi renders. Otherwise we try to round positions down and dimensions up, as not to sqeeze and wrap text.

func (Dot) At ¶

func (dot Dot) At(dpi int) int

At returns dot at a specific resolution in dots per inch.

func (Dot) Ceil ¶

func (dot Dot) Ceil() Dot

func (Dot) CeilHalf ¶

func (dot Dot) CeilHalf() Dot

func (Dot) Floor ¶

func (dot Dot) Floor() Dot

func (Dot) FloorHalf ¶

func (dot Dot) FloorHalf() Dot

func (Dot) Mm ¶

func (dot Dot) Mm() float64

Mm converts dot into mm and returns it.

func (Dot) Round ¶
