Crate stet_graphics 

Graphics foundation for the stet PostScript and PDF rendering stack: colours, the display list, ICC profile management, and mesh / patch shading parsers.

Only depends on stet-fonts, so it is usable on its own when any of these subsystems is what you actually want:

• icc — ICC colour management (CMYK↔sRGB, bulk image conversion, black-point compensation) via moxcms.
• mesh_shading — decoders for PDF Type 4/5 (Gouraud triangle mesh) and Type 6/7 (Coons / tensor patch) shading streams.
• display_list — the DisplayList / DisplayElement types that both the PostScript interpreter and stet-pdf-reader emit into. Custom output devices, PDF rewriters, and diff tools consume these.
• color and device — colour types, line-style primitives, paint-parameter structs, and the PageSink / PageSinkFactory streaming traits.

Most users should use the stet facade crate to render PostScript or PDF, and stet-pdf-reader to parse PDFs into DisplayLists.

Modules

display_list

Display list — records drawing operations for deferred replay to a device.

icc

ICC color profile support via moxcms.

layer_set

Per-render OCG visibility overrides.

mesh_shading

Binary mesh and patch parsers for shading Types 4-7.
