Byte Assets And Blob Input

Recipe includes Roboto Regular for text and tables with no font setup. The registration examples below apply to custom Recipe fonts and to all low-level writer fonts; see Custom Fonts. When supplying your own fonts, createRecipe({ defaultFont: fontFile }) uses your file as the default without loading Roboto. Use createRecipe({ defaultFont: false }) when registering named families instead.

The synchronous Wasm contract is Uint8Array | ArrayBuffer. Register reusable fonts, images, and PDFs by name before using them:

var fontBytes = new Uint8Array(await fontFile.arrayBuffer());
muhammara.registerFont("inter", fontBytes);
muhammara.registerImage("logo", imageBytes, "png");
muhammara.registerPdf("source", sourcePdfBytes);

Blob and File are asynchronous browser sources. Use the matching Async method instead of reading them synchronously:

await muhammara.registerFontAsync("inter", fontFile);
var reader = await muhammara.createReaderAsync(pdfFile);
var modifier = await muhammara.createWriterToModifyAsync(pdfFile);

The low-level API also has async variants for image inspection, TIFF and PDF form creation, copying contexts, append/merge operations, and ContentContext.drawImage. Recipe has registerFontAsync, registerImageAsync, and registerPdfAsync. Recipe image() places a registered image or a page of a registered PDF.

In Node, Buffer works only because it is a Uint8Array subclass. It is not a separate Wasm input type. Filesystem paths, Node streams, and browser-sounding wrappers around those inputs are not supported.
