1// nx_charjudge.nx -- CLI for the v2 character-image judge (core = nx_charjudge_lib, gate = 2// nx_charjudge_gate). Decodes a PNG sovereignly, judges it, prints all axes as JSON. 3// HEADLINE = MIN(composition, palette, contour, face) -- see the lib header for why each axis exists 4// and which adversarial input it kills. Thresholds ride knowledge/charjudge.conf. 5// license_tier: ORIGINAL nx_charjudge <img.png> <label> 6import "nx_syscalls.nx" 7import "nx_itoa_lib.nx" 8import "nx_png_decoder.nx" 9import "nx_charjudge_lib.nx" 10 11func cjc_hw(s: *u8) -> i64 { var n: i64=0; while s[n]!=(0 as u8){n=n+1} sys_write(1,s,n); return 0 } 12func cjc_pn(v: i64) -> i64 { nxi_out(v); return 0 } 13 14func main(argc: i64, argv: *i64) -> i64 { 15 let path: *u8 = argv[1] as *u8 16 let label: *u8 = argv[2] as *u8 17 let lenp: *i64 = sys_mmap(16) as *i64 18 let raw: *u8 = sys_read_file(path, lenp) 19 if (raw as i64) == 0 { cjc_hw("{\x22error\x22:\x22read\x22}\n" as *u8); return 2 } 20 let res: *NxPngResult = nx_png_decode(raw, lenp[0]) 21 if (res as i64) == 0 { cjc_hw("{\x22error\x22:\x22decode\x22}\n" as *u8); return 3 } 22 if res.error_code != 0 { cjc_hw("{\x22error\x22:\x22decode-rc\x22}\n" as *u8); return 3 } 23 let hdr: *NxPngHeader = res.header 24 let w: i64 = hdr.width 25 let h: i64 = hdr.height 26 let ch: i64 = res.n_channels 27 let px: *u8 = res.pixels 28 if w <= 0 { cjc_hw("{\x22error\x22:\x22dims\x22}\n" as *u8); return 3 } 29 let fb: *i64 = sys_mmap(w*h*8) as *i64 30 var q: i64 = 0 31 while q < w*h { 32 var pr: i64 = 0 33 var pg: i64 = 0 34 var pb: i64 = 0 35 if ch >= 3 { pr = px[q*ch] as i64; pg = px[q*ch+1] as i64; pb = px[q*ch+2] as i64 } 36 if ch <= 2 { pr = px[q*ch] as i64; pg = pr; pb = pr } 37 fb[q] = pr + pg*256 + pb*CHJ_MAGIC_65536 38 q = q + 1 39 } 40 let out: *i64 = sys_mmap(96) as *i64 41 chj_judge(fb, w, h, "knowledge/charjudge.conf" as *u8, out) 42 cjc_hw("{\x22label\x22:\x22" as *u8); cjc_hw(label) 43 cjc_hw("\x22,\x22w\x22:" as *u8); cjc_pn(w); cjc_hw(",\x22h\x22:" as *u8); cjc_pn(h) 44 cjc_hw(",\x22composition\x22:" as *u8); cjc_pn(out[0]) 45 cjc_hw(",\x22palette_axis\x22:" as *u8); cjc_pn(out[1]) 46 cjc_hw(",\x22contour_axis\x22:" as *u8); cjc_pn(out[2]) 47 cjc_hw(",\x22face_axis\x22:" as *u8); cjc_pn(out[3]) 48 cjc_hw(",\x22CHARJUDGE\x22:" as *u8); cjc_pn(out[4]) 49 cjc_hw(",\x22raw\x22:{\x22smooth_permil\x22:" as *u8); cjc_pn(out[5]) 50 cjc_hw(",\x22detail_permil\x22:" as *u8); cjc_pn(out[6]) 51 cjc_hw(",\x22palette_buckets\x22:" as *u8); cjc_pn(out[7]) 52 cjc_hw(",\x22coherent_permil\x22:" as *u8); cjc_pn(out[8]) 53 cjc_hw(",\x22edge_total\x22:" as *u8); cjc_pn(out[9]) 54 cjc_hw("}}\n" as *u8) 55 return 0 56}
