Every subband weight is 1 at every Qfactor, so the steps are + MSE-optimal, as the guideline's are from Qfactor=97 up; without the MCT + every component is independent data with unit colour gain. The Qfactor + still sets the reference step, so a Qfactor gives larger files and smaller + errors: on an 8-bit RGB image, 28-54% more bits and 2.6-3.8 dB more PSNR at + Qfactor=30 to 90. The default, Qweights=visual, is unchanged. + estimate_qfactor --weights flat recovers the Qfactor of such files. + Changed: + * Qfactor on sub-sampled (4:2:0 or 4:2:2) colour input follows version 2.0 of + the JPEG Qfactor guideline, "Controlling JPEG 2000 image quality using a + single parameter (Qfactor)" (ISO/IEC JTC 1/SC 29/WG 1 N101553). Its chroma + weights include the gain of upsampling the component for display, 2 for + 4:2:0 and 1.4142 for 4:2:2, on every subband including LL; the encoder used + the version 1.0 weights, which leave it out. Below Qfactor=97 the chroma + steps of such files are finer by up to 2 (4:2:0) or 1.4142 (4:2:2) times, + so the files are larger: a 1024x1024 4:2:0 test image grows by 41% at + Qfactor=30, 23% at 75 and 9% at 90. Output for gray, gray + alpha and 4:4:4 + colour input, and all output without Qfactor, is byte-identical. The + experimental analytic weighting (Qcsf=mannos|daly) applies the same gain to + sub-sampled components. estimate_qfactor follows the new weights, so on a + sub-sampled file written by 0.25.0 or earlier it finds the Qfactor from the + luminance component only and reports a mismatch on the chroma components. + Fixed: + * On the single-tile reuse path (invoke_line_based_stream_reuse() and + invoke_line_based_direct() after enable_single_tile_reuse(true)), a frame + whose headers differed from the previous frame's could decode with the + previous frame's step sizes, packet order or line-decoder sizes. The + decoder rebuilt its reused structure only when a few header values changed + (SIZ, part of COD, the first QCD step size, and the numbers of COC, QCC and + RGN segments); it ignored the rest of the main header, the tile-part + headers and the resolution reduction. It now compares a hash of every + marker segment that shapes the tile, in the main header and the tile-part + headers, together with the reduction. A frame whose tile-part header gives + a component another number of decomposition levels, which 0.25.0 refused, + now decodes as well. Frames with unchanged headers reuse the structure as + fast as before (29.5 ms per 4K frame). (#545) + * Every source file includes the standard headers it uses, so the library and + tools build with standard libraries that no longer bring one header in + through another, such as the libc++ of current Emscripten releases + (std::strtoull in jpip_response.cpp). + +------------------------------------------------------------------- Old: ---- v0.25.0.tar.gz New: ---- v0.26.0.tar.gz ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Other differences: ------------------ ++++++ openhtj2k.spec ++++++ --- /var/tmp/diff_new_pack.GtUxO0/_old 2026-11-10 14:45:41.447813094 +0100 +++ /var/tmp/diff_new_pack.GtUxO0/_new 2026-11-10 14:45:41.449813178 +0100 @@ -17,7 +17,7 @@ Name: openhtj2k -Version: 0.25.0 +Version: 0.26.0 Release: 0 Summary: An open source implementation of ITU-T Rec.814 | ISO 15444-15 (a.k.a.
