Crate rasterrocket_render 

raster

Pure software rasterizer for PDF page content — no I/O, no PDF parsing, no SIMD (Phase 1).

Phase 1 scope

Foundation types only: pixel buffers, path geometry, edge tables, clip regions, halftone screens, and graphics state. Rendering (pipe, fill, stroke, image, shading, glyph, transparency) is Phase 2.

Module layout

• types — raster-local enums and constants (re-exports color types)
• bitmap — Bitmap<P> and AaBuf
• path — Path, PathBuilder, Bezier flattening, stroke adjustment
• xpath — XPath edge table (flattened, matrix-transformed segments)
• scanner — XPathScanner and crate::ScanIterator (scanline span emission)
• clip — Clip (rect + arbitrary path clip stack)
• screen — HalftoneScreen (Bayer / stochastic threshold matrix)
• state — GraphicsState and StateStack
• pipe — compositing pipeline (simple, AA, general; blend modes; Pattern trait)

Modules

bitmap

Pixel buffers and the anti-aliasing scratch buffer.

clip

Clip region: an axis-aligned rectangle intersected with zero or more arbitrary path clip regions.

fill

Filled-path rasterization — replaces Splash::fill, Splash::eoFill, and the core of Splash::fillWithPattern.

glyph

Glyph bitmap blitting — replaces Splash::fillGlyph2.

image

Image and image-mask rendering — replaces Splash::fillImageMask, Splash::drawImage, and the four scaleImage* / scaleMask* helpers.

path

PDF path geometry: points, flags, subpath state machine, and builder API.

pipe

Compositing pipeline — replaces SplashPipe and its pipeRun* family.

scanner

Scanline intersection lists for path fill and clip.

screen

Halftone threshold screen for Mono1 (1-bit) output.

shading

Shaded fills — gradient patterns and Gouraud-shaded triangles.

simd

SIMD-accelerated hot paths for the rasterizer.

state

Graphics state and save/restore stack.

stroke

Stroke rasterization.

tiling

Tiling pattern source for the compositing pipeline.

transparency

Transparency group compositing — replaces Splash::beginTransparencyGroup, Splash::endTransparencyGroup, and Splash::paintTransparencyGroup.

types

Raster-local enums and workspace-wide constants.

xpath

Flattened, matrix-transformed path edge table.
