Functions

apply_subsetting_if_enabled 🔒

Applies font subsetting if enabled and text is provided.

apply_subsetting_to_chain

Applies font subsetting to a fallback chain to reduce PDF file size.

extract_primary_fonts

find_font_variant_in_paths 🔒

Searches for a specific font variant file in custom paths.

format_size 🔒

Formats a byte size in a human-readable format.

get_default_fallback_fonts

get_font_aliases 🔒

Returns common aliases for a font name.

load_builtin_font_family

Attempts to load a built-in PDF font family using only the PDF built-in fonts without any system font dependencies. This ensures consistent character spacing across all platforms and avoids kerning issues.

load_custom_font_family

Attempts to load a font family from custom paths first, then falls back to system fonts. This function searches user-specified directories or files before looking in system fonts.

load_font_family_with_variants

Loads a font family with proper variant files (Bold, Italic, BoldItalic).

load_font_with_config

Loads a font family using the provided FontConfig, with intelligent fallback. This is the main entry point for loading fonts with custom configuration.

load_font_with_fallback_chain

Loads fonts and creates a fallback chain for handling mixed-script documents.

load_font_with_fallbacks

Loads a font with fallback support for better coverage (legacy function).

load_system_font_bytes_fallback 🔒

Attempts to find a suitable system font for built-in font metrics. Falls back to any available system font if specific candidates aren’t found.

load_system_font_family_simple

Attempts to load an arbitrary system font family and embed it into the PDF.

load_unicode_system_font

Loads a Unicode-capable system font with good international character support.

subset_chain 🔒

Subsets a single fallback chain by subsetting each font based on what it renders.

subset_single_font 🔒

Subsets a single FontData based on the provided text.

try_embedded_font_family 🔒
