Types

type QPdf

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

QPdf abstracts the CLI tool QPDF and implements the gotenberg.PdfEngine interface.

func (*QPdf) Convert

func (engine *QPdf) Convert(ctx context.Context, logger *zap.Logger, formats gotenberg.PdfFormats, inputPath, outputPath string) error

Convert is not available in this implementation.

func (*QPdf) Descriptor

func (engine *QPdf) Descriptor() gotenberg.ModuleDescriptor

Descriptor returns a QPdf's module descriptor.

func (*QPdf) Merge

func (engine *QPdf) Merge(ctx context.Context, logger *zap.Logger, inputPaths []string, outputPath string) error

Merge combines multiple PDFs into a single PDF.

func (*QPdf) Provision

func (engine *QPdf) Provision(ctx *gotenberg.Context) error

Provision sets the modules properties.

func (*QPdf) ReadMetadata

func (engine *QPdf) ReadMetadata(ctx context.Context, logger *zap.Logger, inputPath string) (map[string]interface{}, error)

ReadMetadata is not available in this implementation.

func (*QPdf) Validate

func (engine *QPdf) Validate() error

Validate validates the module properties.

func (*QPdf) WriteMetadata

func (engine *QPdf) WriteMetadata(ctx context.Context, logger *zap.Logger, metadata map[string]interface{}, inputPath string) error

WriteMetadata is not available in this implementation.
