about

nx_img_convert.nx -- sovereign image CONVERT (resize -> encode), end-to-end. Composes the sovereign resampler (nx_img_scale) + the sovereign PNG encoder (nx_png_write) -- ZERO 3rd-party. This is the "upscaling/downscaling when media is converted" path: pixels in -> scaled -> real PNG out that any viewer can see. Reuses existing organs (DRY #15) rather than rebuilding decode/ encode that a parallel media-stack workstream already shipped. The input-decode side (real PNG/JPEG -> pixels via nx_png_decode / nx_jpeg_decode -> here) is the immediate next rung. license_tier: ORIGINAL
