Convert Cdx To Jpg Fixed //free\\ Now

The final stage converts the raw pixel buffer (typically RGBA) into a JPEG. This introduces its own challenge: JPEG is lossy. To maintain the "fixed" visual fidelity of chemical diagrams (where sharp edges between bonds and white background are critical), the encoder must use a fixed quantization table. A quality setting of 85-90% (out of 100) is empirically optimal: it compresses flat white backgrounds effectively while preserving the high-frequency edges of benzene rings without visible ringing artifacts.
