scholium.slide_processor.SlideProcessor#

class SlideProcessor(pandoc_template='beamer', resolution=(1920, 1080))[source]#

Bases: PandocBackend

Pandoc/Beamer slide processor.

Preserved as a thin subclass of PandocBackend so the original constructor signature SlideProcessor(pandoc_template=..., resolution=...) continues to work. New code should use the backend registry instead:

from scholium.slides import get_backend
backend = get_backend("pandoc", resolution=(1920, 1080))

Initialise the backend.

Parameters:

resolution (Tuple[int, int]) – Target image resolution as (width, height).
backend_config – Backend-specific options from config.yaml.

Methods

`markdown_to_pdf`	Convert markdown to PDF using pandoc.
`pdf_to_images`	Rasterise a PDF into PNG slides at the configured resolution.
`probe_dependencies`	Check pandoc + a LaTeX engine on `PATH`.
`process`	Run the markdown → PDF → PNG pipeline.
