Thank to Robin Watts for the suggestion. + +Adapt full buffer case in jcmainct.c for use with scaled DCT. +Thank to Sergii Biloshytskyi for the suggestion. + +Add type identifier for declaration of noreturn functions. +Thank to Brett L. Moore for the suggestion. + +Correct argument type in format string, avoid compiler warnings. +Thank to Vincent Torri for hint. + +Add missing #include directives in configuration checks, avoid +configuration errors. Thank to John Spencer for the hint. + + +Version 8d 15-Jan-2012 +----------------------- + +Add cjpeg -rgb option to create RGB JPEG files. +Using this switch suppresses the conversion from RGB +colorspace input to the default YCbCr JPEG colorspace. +This feature allows true lossless JPEG coding of RGB color images. +The recommended command for this purpose is currently +cjpeg -rgb -block 1 -arithmetic. +SmartScale capable decoder (introduced with IJG JPEG 8) required. +Thank to Michael Koch for the initial suggestion. + +Add option to disable the region adjustment in the transupp crop code. +Thank to Jeffrey Friedl for the suggestion. + +Thank to Richard Jones and Edd Dawson for various minor corrections. + +Thank to Akim Demaille for configure.ac cleanup. + + Version 8c 16-Jan-2011 ----------------------- Index: reactos/dll/3rdparty/libjpeg/cjpeg.c =================================================================== --- reactos/dll/3rdparty/libjpeg/cjpeg.c (revision 58310) +++ reactos/dll/3rdparty/libjpeg/cjpeg.c (working copy) @@ -2,7 +2,7 @@ * cjpeg.c * * Copyright (C) 1991-1998, Thomas G.
