Function: createOpentypeTextMeasurerFromBuffers()
function createOpentypeTextMeasurerFromBuffers(fontBuffers: FontBuffer[], fontMapping?: FontMapping): Promise<OpentypeTextMeasurer | null>;Create a text measurer from caller-provided font buffers.
This low-level helper is useful when rendering in an environment where fonts
are bundled as bytes instead of discovered from the OS. It dynamically imports
opentype.js and returns null if no fonts can be parsed or the optional
dependency is unavailable.
Parameters
fontBuffers
Font file bytes to parse.
fontMapping?
Optional PPTX font name to replacement font mapping.
Returns
Promise<OpentypeTextMeasurer | null>
A text measurer, or null when setup is not possible.
