Namespace IronSoftware.Pdfium.QPdf

Classes

PdfJsonStreamDataMode

Specifies how stream data should be handled in JSON output. Maps to QPDF's qpdf_json_stream_data_e enum.

PdfStreamDecodeLevel

Specifies the level of stream decoding for JSON output. Maps to QPDF's qpdf_stream_decode_level_e enum.

QPdfCompressionFlags

Tunable qpdf compression flags. Mirrors the subset of QPDFJob options that IronPdf exposes during advanced compression.

Defaults are tuned for size â€” they enable CoalesceContents and DecodeGeneralizedStreams, which produce smaller output than the legacy CompressAndSaveAs(bytes, path, jpeg: null, password) overload.

To exactly reproduce legacy output, use IronSoftware.Pdfium.QPdf.QPdfCompressionFlags.Legacy(System.Nullable{System.Int32}) (internal preset the legacy overload itself uses).

Example - opt in to image re-encoding:

var flags = new QPdfCompressionFlags
{
    OptimizeImages = true,
    JpegQuality   = 70
};

QPdfFlags

Represents options for configuring QPdf processing and output behavior.

QPdfJobException

Thrown when a qpdfjob_run_from_json invocation returns a non-zero exit code. Carries the raw qpdf exit code so callers can branch on it without string parsing.

QPdfJsonOptions

Options for converting PDF to JSON format.

QPdfObjectStreams

Object stream mode written into the output PDF. Maps directly to qpdf's --object-streams values.
