説明

For use with jsdom package which simulates browser DOM in node.js and use node-canvas for canvas implementation a support to load fonts (truetype and openfont) from a buffer/content is needed. Because in HTML a custom font face can be specified as an URL, jsdom resolves this URL to a buffer/content by itself. So registration with buffer/content should be possible.

See https://github.com/tmpvar/jsdom/issues/744 for more details.

調査方針: This issue requests the ability to register custom fonts from a buffer. Start by examining the existing font registration code in node canvas, likely in `src/Font.cc` or `src/Font.h`. Review how fonts are currently loaded from files and identify the APIs that need modification. The linked jsdom issue (tmpvar/jsdom#744) provides context about the use case. Consider using Cairo's `cairo ft font face create for ft face` or similar functions to load fonts from memory. Look for existing discussions in the issue comments for any proposed approaches.
