SkiaCanvas

class SkiaCanvas(canvas: Canvas)

PdfCanvas backed by a raw org.jetbrains.skia.Canvas (Skiko).

Same rendering engine Compose Multiplatform rides on for JVM Desktop and iOS — minus the Compose runtime. Pure-Skia means this adapter is the right choice for:

Server-side rasterization — PDF → PNG, headless thumbnail generation, CI pipelines.
CLI tools — anything that wants pixels without dragging in androidx.compose.runtime.
Smaller dependency footprint — Skiko alone is significantly less than Compose Multiplatform.

Pair with PdfPageRasterizer for the common "give me a ByteArray of a page's PNG" use case.
