about

nx_xfade_demo.nx -- VISIBLE proof of R4: crossfade two REAL gallery photos with the SMOOTHSTEP curve and write 5 BMPs (0/25/50/75/100%) you can open on Windows to SEE the smooth dissolve. Decodes real PNGs, blends via nx_xfade_frame, writes via nx_bmp. Sovereign throughout. Output: knowledge/staging/media/xfade_0.bmp .. xfade_4.bmp license_tier: ORIGINAL
