nx_img_bytes_to_rgb.nx

nx_img_bytes_to_rgb.nx -- decode an IN-MEMORY encoded image buffer -> interleaved 8-bit RGB (w*h*3, row-major). THE single decode chokepoint: the bytes-in core shared by nx_img_to_rgb (path variant), the Windows GUI (read_local + this), the reader/tiler, and -- via the nx_image_gray projection -- the whole reverse-image search plane. FORMAT ROSTER (2026-08-05, each gate-proven): JPEG (baseline + progressive + DRI/RST restart markers) · GIF87a/89a (palette colour, de-interlaced, first frame) · WebP VP8L lossless (lossy VP8 refuses -- C3 pending) · BMP (BI_RGB 1/4/8/24/32 + RLE8, both row orders) · TIFF (baseline strips, none+PackBits, gray/RGB/palette, LE+BE) · PNG (all colour types incl palette, sub-byte depths, Adam7 interlace; 16-bit high byte) . TGA (types 1/2/3 + RLE 9/10/11, origin bit honoured) . PCX (8-bit palette, 24-bit planar, 1-bit) . ICO/CUR (largest frame; DIB or PNG body) . PNM P1-P6. Returns the rgb buffer + sets out_wh[0]=w, out_wh[1]=h; returns 0 on failure/unsupported -- NEVER a wrong image. license_tier: ORIGINAL
