Functions ¶

func NewStreamAware ¶

func NewStreamAware(s scanner.Scanner) *streamAware

func ParseHintStream ¶

func ParseHintStream(data []byte, dict *raw.DictObj, npages int) (*raw.HintTable, error)

ParseHintStream parses the hint stream data. The dict is the dictionary of the hint stream object (containing S, T, O, etc.). npages is the number of pages in the document (from Linearization dict).

Types ¶

type Cache ¶

type Cache interface {
	Get(ref raw.ObjectRef) (raw.Object, bool)
	Put(ref raw.ObjectRef, obj raw.Object)
}

type Config ¶

type Config struct {
	Recovery    recovery.Strategy
	XRef        xref.ResolverConfig
	MaxIndirect int
	Security    security.Handler
	Limits      security.Limits
	Cache       Cache
	Password    string
}

Config controls high-level PDF parsing (xref resolution + object loading).

type DocumentParser ¶

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

DocumentParser builds a raw.Document using xref tables/streams and the object loader.

func NewDocumentParser ¶

func NewDocumentParser(cfg Config) *DocumentParser

func (*DocumentParser) Parse ¶

func (p *DocumentParser) Parse(ctx context.Context, r io.ReaderAt) (*raw.Document, error)

func (*DocumentParser) SetPassword ¶

func (p *DocumentParser) SetPassword(pwd string)

SetPassword updates the password for decryption when parsing encrypted PDFs.

type ObjectLoader ¶

type ObjectLoader interface {
	Load(ctx context.Context, ref raw.ObjectRef) (raw.Object, error)
	LoadIndirect(ctx context.Context, ref raw.ObjectRef, depth int) (raw.Object, error)
}

type ObjectLoaderBuilder ¶

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

func (*ObjectLoaderBuilder) Build ¶

func (b *ObjectLoaderBuilder) Build() (ObjectLoader, error)

func (*ObjectLoaderBuilder) WithCache ¶

func (b *ObjectLoaderBuilder) WithCache(c Cache) *ObjectLoaderBuilder

func (*ObjectLoaderBuilder) WithLimits ¶

func (b *ObjectLoaderBuilder) WithLimits(l security.Limits) *ObjectLoaderBuilder

func (*ObjectLoaderBuilder) WithReader ¶

func (b *ObjectLoaderBuilder) WithReader(r io.ReaderAt) *ObjectLoaderBuilder

func (*ObjectLoaderBuilder) WithSecurity ¶

func (b *ObjectLoaderBuilder) WithSecurity(h security.Handler) *ObjectLoaderBuilder

func (*ObjectLoaderBuilder) WithXRef ¶

func (b *ObjectLoaderBuilder) WithXRef(table xref.Table) *ObjectLoaderBuilder
