attachment
fun attachment(fileName: String, bytes: ByteArray, mimeType: String = "application/octet-stream", description: String? = null)
Embeds a file into the document. Repeatable — each call adds another attachment in source order. Only honoured by the JVM/Desktop backend; silently skipped on iOS and Android (see PdfAttachment).
Parameters
fileName
name shown to the user (e.g. "invoice.xml").
bytes
raw file contents.
mimeType
MIME type recorded as the embedded stream subtype.
description
optional human-readable description.
