    PdfBytes

    source
    type PdfBytes = Bytes

    PDF byte strings and byte streams.

    This is an alias for MoonBit Bytes because PDF strings and streams are byte sequences, not Unicode text. Use String only after an explicit PDF text decoding step.

    PdfName

    source

    A PDF name token stored as its raw bytes without the leading slash.

    Names are byte-oriented in the PDF file format. Keeping the original bytes avoids accidental UTF-16 or UTF-8 interpretation while still allowing explicit views and owned-byte access.

    PdfObject

    source

    The core in-memory representation of a parsed PDF object.

    Strings and names are byte-oriented PDF values, not MoonBit Unicode strings. PdfIndirect(number) is an unresolved reference by object number; callers that need the referenced object should resolve it through a PdfDocument.

    PdfReal is written rounded (to six decimals below 0.0001 in magnitude, otherwise to twelve significant digits); PdfExactReal is written exactly, as the shortest decimal that reads back as the value (see pdf_write_exact_real), for numbers such as transformation coefficients that no fixed precision serves. The parser never produces PdfExactReal: what it writes reads back as PdfReal (or PdfInteger).

    PdfRectangle

    source

    A normalized rectangle in PDF user-space coordinates.

    min_x and min_y are always the lower bounds, and max_x and max_y are always the upper bounds. Parsers normalize PDF rectangle arrays whose coordinates are written in the opposite order.

    Point2

    source

    A two-dimensional point in PDF user-space coordinates.

    PdfError

    Strip cpdf add-text %URL[text|url] markup from one line.

    The returned URL spans use byte offsets in the stripped visible text, as in cpdf's get_urls_line helper.

    pdf_addtext_initial_line_offsets

    source
    fn pdf_addtext_initial_line_offsets(position : 
    PdfPosition    , line_count : Int, line_spacing : Double, font_size : Double) -> (Double, Double)

    source
    fn pdf_addtext_justification_offset(rotation : PdfAddTextRotation, longest_width : Double, width : Double, position : 
    PdfPosition    , justification : PdfAddTextJustification) -> Double

    Return cpdf's add-text justification offset for the current line.

    longest_width is the maximum rendered width among the expanded text lines, and width is the current line width.

    pdf_addtext_line_advance

    source
    fn pdf_addtext_line_advance(rotation : PdfAddTextRotation, line_spacing : Double, font_size : Double) -> (Double, Double)

    Resolve cpdf add-text placement values for one line.

    This combines cpdf's calculate_position, diagonal offset correction, justification offset application, explicit text rotation, and rotation-origin offset selection.

    pdf_addtext_rotation_offsets

    source
    fn pdf_addtext_rotation_offsets(position : 
    PdfPosition    , rotation : PdfAddTextRotation, text_width : Double) -> (Double, Double)

    Return cpdf's rotation-dependent text origin offset.

    pdf_addtext_rotation_radians

    source
    fn pdf_addtext_rotation_radians(rotation : PdfAddTextRotation) -> Double

    Convert cpdf add-text's explicit rotation enum to content rotation radians.
