DRC | 0571e17 | 2011-05-31 20:17:16 +0000 | [diff] [blame] | 8 | [2] The inclusion of libjpeg v7 and v8 emulation as well as arithmetic coding |
| 9 | support in libjpeg-turbo v1.1.0 introduced several new error constants in |
| 10 | jerror.h, and these were mistakenly enabled for all emulation modes, causing |
DRC | fa9ff8e | 2011-06-21 06:17:10 +0000 | [diff] [blame] | 11 | the error enum in libjpeg-turbo to sometimes have different values than the |
| 12 | same enum in libjpeg. This represents an ABI incompatibility, and it caused |
| 13 | problems with rare applications that took specific action based on a particular |
| 14 | error value. The fix was to include the new error constants conditionally |
| 15 | based on whether libjpeg v7 or v8 emulation was enabled. |

| 18 | fail to compile if the Windows system headers were included before jpeglib.h. |

DRC | c412184 | 2011-12-01 11:11:29 +0000 | [diff] [blame^] | 24 | [5] Fixed out-of-bounds read in SSE2 SIMD code that occurred when decompressing |
| 25 | a JPEG image to a bitmap buffer whose size was not a multiple of 16 bytes. |
| 26 | This was more of an annoyance than an actual bug, since it did not cause any |
| 27 | actual run-time problems, but the issue showed up when running libjpeg-turbo in |
| 28 | valgrind. See http://crbug.com/72399 for more information. |

DRC | e43d21d | 2011-04-17 15:28:32 +0000 | [diff] [blame] | 37 | [2] libjpeg-turbo's accelerated Huffman decoder previously ignored unexpected |
| 38 | markers found in the middle of the JPEG data stream during decompression. It |
| 39 | will now hand off decoding of a particular block to the unaccelerated Huffman |
| 40 | decoder if an unexpected marker is found, so that the unaccelerated Huffman |
| 41 | decoder can generate an appropriate warning. |

DRC | 47aaf6f | 2011-03-22 05:40:39 +0000 | [diff] [blame] | 43 | [3] Older versions of MinGW64 prefixed symbol names with underscores by |
DRC | 1da7858 | 2011-03-22 09:34:01 +0000 | [diff] [blame] | 44 | default, which differed from the behavior of 64-bit Visual C++. MinGW64 1.0 |
| 45 | has adopted the behavior of 64-bit Visual C++ as the default, so to accommodate |
| 46 | this, the libjpeg-turbo SIMD function names are no longer prefixed with an |
| 47 | underscore when building with MinGW64. This means that, when building |
| 48 | libjpeg-turbo with older versions of MinGW64, you will now have to add |
| 49 | -fno-leading-underscore to the CFLAGS. |

| 56 | enabled. This specifically caused the jpegoptim program to fail if it was |

DRC | 72abc29 | 2011-02-18 01:45:24 +0000 | [diff] [blame] | 70 | [1] The algorithm used by the SIMD quantization function cannot produce correct |
| 71 | results when the JPEG quality is >= 98 and the fast integer forward DCT is |
DRC | bb4465f | 2011-02-18 02:41:03 +0000 | [diff] [blame] | 72 | used. Thus, the non-SIMD quantization function is now used for those cases, |
| 73 | and libjpeg-turbo should now produce identical output to libjpeg v6b in all |
| 74 | cases. |
DRC | e1716b8 | 2011-02-18 03:19:43 +0000 | [diff] [blame] | 75 | |
DRC | 72abc29 | 2011-02-18 01:45:24 +0000 | [diff] [blame] | 76 | [2] Despite the above, the fast integer forward DCT still degrades somewhat for |
| 77 | JPEG qualities greater than 95, so TurboJPEG/OSS will now automatically use the |
| 78 | slow integer forward DCT when generating JPEG images of quality 96 or greater. |
| 79 | This reduces compression performance by as much as 15% for these high-quality |
| 80 | images but is necessary to ensure that the images are perceptually lossless. |
DRC | bb4465f | 2011-02-18 02:41:03 +0000 | [diff] [blame] | 81 | It also ensures that the library can avoid the performance pitfall created by |
