Changelog #

1.0.0 #

First stable release. Changes since 0.1.0:

Color: Lab, CalGray, and CalRGB CIE-based color spaces; calibrated Separation/DeviceN alternate spaces; Indexed color; and pure-Dart DeviceCMYK JPEG decoding for correct print-color rendering.
Fonts: a Type 1 parser; CFF improvements (seac accented-glyph composition, encoding supplements, per-FD font-matrix composition); TrueType post-table glyph-name lookup when there is no usable cmap; custom /Encoding and ZapfDingbats glyph resolution; vertical writing mode (Identity-V / WMode 1) for Type 0 fonts; and CJK CMap support for non-embedded Adobe-Japan1 and legacy GBK fonts.
Transparency: isolated knockout groups (/K true); optional content groups (OCG) with visibility expressions for correct layer handling.
Images: full-resolution /Mask stencils, and JBIG2 pattern dictionaries with halftone regions.
Patterns: tiling-pattern and shading-pattern fills rendered through glyph outlines for text.
Text: paragraph-aware reflow extraction for reading view; rotated text selection geometry.
Robustness: pages with invalid bounding boxes fall back to valid geometry instead of collapsing.
Document-AI seam: PdfDocumentContext.of(document) gathers a document's text, form fields, and annotations into a clean, serializable shape for a host-supplied language model, and PdfDocumentActionSink describes the editing actions an agent can drive. A thin adapter over the existing extraction/editing surface — the model and transport are host-provided.

Initial release.

Content-stream interpreter covering the full operator set: paths, clipping, transparency groups, soft masks, blend modes, optional content, type 0–4 functions.
Device interface: implement one class to render PDF pages anywhere.
Font engine: Type 1, TrueType, CFF, Type 0/CID, Type 3; embedded and standard-14 metrics.
Shadings 1–7 including mesh parsing; tiling and shading patterns.
Color: ICC profiles (gray TRC, matrix/TRC, mft1/mft2/mAB LUTs), Separation/DeviceN, Indexed, Lab.
Text extraction with selection geometry, search, and rotation-aware page geometry.
Annotation appearance rendering and form-field appearance support.
