Embed encoded JPEG bytes directly via /DCTDecode (no re-encode). width/height must match the JPEG's own dimensions. Set grayscale for a single-component (DeviceGray) JPEG.

jpx

fun jpx(jp2Bytes: ByteArray, width: Int, height: Int): PdfImage

Embed a JPEG 2000 (.jp2) codestream directly via /JPXDecode (no re-encode).

8-bit RGBA, 4 bytes per pixel (R,G,B,A). The alpha channel becomes a /SMask; if every pixel is fully opaque the mask is omitted.
