Types

type Error

type Error int32

Error represents an NDK error code.

func (Error) Error

func (e Error) Error() string

type FAMILY_VARIANT

type FAMILY_VARIANT int32

const (
	AFAMILY_VARIANT_DEFAULT FAMILY_VARIANT = 0
	AFAMILY_VARIANT_COMPACT FAMILY_VARIANT = 1
	AFAMILY_VARIANT_ELEGANT FAMILY_VARIANT = 2
)

type Font

type Font struct {
	// contains filtered or unexported fields
}

Font wraps the NDK AFont handle.

func NewFontFromPointer

func NewFontFromPointer(ptr unsafe.Pointer) *Font

NewFontFromPointer wraps a raw AFont pointer.

func (*Font) Close

func (h *Font) Close() error

func (h *Font) GetFontFilePath() string

GetFontFilePath returns the value directly.

func (*Font) GetLocale

func (h *Font) GetLocale() string

GetLocale returns the value directly.

func (*Font) IsItalic

func (h *Font) IsItalic() bool

IsItalic returns the value directly.

func (*Font) Pointer

func (h *Font) Pointer() unsafe.Pointer

Pointer returns the underlying pointer as unsafe.Pointer.

func (*Font) Weight

func (h *Font) Weight() uint16

Weight returns the value directly.

type Matcher

type Matcher struct {
	// contains filtered or unexported fields
}

Matcher wraps the NDK AFontMatcher handle.

func NewMatcher

func NewMatcher() *Matcher

NewMatcher creates a new Matcher.

func NewMatcherFromPointer

func NewMatcherFromPointer(ptr unsafe.Pointer) *Matcher

NewMatcherFromPointer wraps a raw AFontMatcher pointer.

func (*Matcher) Close

func (h *Matcher) Close() error

Close releases the underlying NDK handle.

func (*Matcher) Match

func (h *Matcher) Match(familyName string, text *uint16, textLength uint32, runLengthOut *uint32) *Font

Match creates a new Font from this Matcher.

func (*Matcher) Pointer

func (h *Matcher) Pointer() unsafe.Pointer

Pointer returns the underlying pointer as unsafe.Pointer.

func (*Matcher) SetFamilyVariant

func (h *Matcher) SetFamilyVariant(familyVariant uint32)

SetFamilyVariant calls the underlying NDK function.

func (*Matcher) SetLocales

func (h *Matcher) SetLocales(languageTags string)

SetLocales calls the underlying NDK function.

func (*Matcher) SetStyle

func (h *Matcher) SetStyle(weight uint16, italic bool) *Matcher

SetStyle sets a property and returns the receiver for chaining.

type SystemFontIterator

type SystemFontIterator struct {
	// contains filtered or unexported fields
}

SystemFontIterator wraps the NDK ASystemFontIterator handle.

func ASystemFontIterator_open

func ASystemFontIterator_open() *SystemFontIterator

ASystemFontIterator_open calls the underlying C function.

func NewSystemFontIteratorFromPointer

func NewSystemFontIteratorFromPointer(ptr unsafe.Pointer) *SystemFontIterator
