about

nx_jpeg_ppm_dump_test.nx -- COLOR proof dumper for the bits-up JPEG decoder. Reads the staged real source.jpg, decodes it to full-resolution RGB via nx_jpeg_decode_rgb (decode + chroma upsample + YCbCr->RGB), and writes a binary PPM (P6) so the Windows GDI+ decode can be diffed against it per-channel. Asserts dims == 239x178, then emits the PPM. expect_exit: 0 license_tier: ORIGINAL
