Functions

apply_scale_to_svg 🔒

Apply a direct scale to the provided SVG markup by inserting a <g transform="scale(...)"> around the SVG contents and multiplying simple numeric width/height attributes when present. It also adjusts a viewBox attribute’s width/height so that SVGs that rely on viewBox sizing are not cropped after applying the transform.

compute_auto_scale 🔒

Given an SVG and a candidate scale, determine the final scale so that the rendered image does not exceed the specified maximum ratio of the provided page width/height. The function returns a scale that is at most candidate_scale.

ensure_browser

Initialize or check the shared headless Chrome instance used for Mermaid rendering.

ensure_helper_file 🔒

extract_dpi_from_svg 🔒

Extract data-dpi=“NNN” if present (used when SVGs embed DPI metadata).

extract_svg_intrinsic_px 🔒

Fast heuristic to extract intrinsic width/height in pixels from an SVG string.

get_browser

get_pool_tab 🔒

sanitize_svg_for_printpdf 🔒

Simple sanitizer used before passing SVGs to printpdf.

shutdown_browser

Shutdown and kill any spawned Chrome used by Mermaid rendering. This ensures the process doesn’t keep child processes or background threads alive which can prevent the main program from exiting when its output is piped.

strip_slice_class_from_path_tags 🔒

Temporary workaround for a printpdf parsing bug: remove class="pieCircle" when it appears inside <path ...> tags only.
