Functions

func AspectRatio

func AspectRatio(srcRect image.Point, toResize uint64) image.Point

AspectRatio returns geometry that conforms to the aspect ratio.

func BigMergeFractionalPotions

func BigMergeFractionalPotions(sign bool, integer, fractional uint64, fractionalLength uint8) (dst *decimal.Big)

BigMergeFractionalPotions compose a decimal number with a sign, integer, and fractional parts.

func BigSeperateFractionalPotions

func BigSeperateFractionalPotions(src *decimal.Big) (sign bool, integer, fractional uint64, fractionalLength uint8)

BigSeperateFractionalPotions decompose a decimal number with a sign, integer, and fractional parts.

func FractionalStringify

func FractionalStringify(fractional, fractionalLength int, showPoint bool) (formatted string)

FractionalStringify is a formatting function for a fractional part number.

func MergeSignFromUInt64

func MergeSignFromUInt64(sign bool, src uint64) (dst int64)

MergeSignFromUInt64 composes a signed integer with a sign and positive integer.

func SplitSignFromInt64

func SplitSignFromInt64(src int64) (sign bool, dst uint64)

SplitSignFromInt64 decomposes a signed integer with a sign and positive integer.
