ziproxy 2.6.0 (Default branch)
Image Ziproxy is a high-performance forwarding (non-caching) HTTP proxy that gzips text and HTML files, and reduces the size of images by converting them to lower quality JPEGs or JPEG 2000. It is intended to increase the speed for low-speed Internet connections (mobile, dial-up, other). It's suitable for both home and professional usage. Ziproxy is fully configurable and also features transparent proxy mode, HTML/JS/CSS optimization, operation in daemon mode, a detailed access log with compression statistics, basic authentication, and more. License: GNU General Public License (GPL) Changes:
An Ad-Blocker system was added. Logging of usernames was added when using authentication. Support was added for a host exception list when using the BindOutgoing (which will solve problems with certain Web sites). A bug which prevented image compression under certain circumstances was fixed. A Russian translation of the documentation was added. Miscellaneous changes and bugfixes were made. Image

pfsoutjpeghdr(1)					      General Commands Manual						  pfsoutjpeghdr(1)

NAME

       pfsoutjpeghdr - Write images or frames in JPEG-HDR format

SYNOPSIS

       pfsoutjpeghdr (<file> [--linear] [--quality <val>] [--correction <correct>] [--frames <range>])	[<file>...]

DESCRIPTION

       Use  this  command to write JPEG file with HDR extension. This software makes use of the High Dynamic Range Imaging Library from Sunnybrook
       Technologies Inc. (c) Sunnybrook Inc. 2005

OPTIONS

       --quality <val>, -q <val>
	      The --quality setting controls the overall compression/quality trade-off, with 100 being the maximum setting, producing  the  lowest
	      losses  and  the largest output files.  Quality settings below 70 may result in significant image degradation, and should be avoided
	      in critical applications. Default: --quality=90

       --correction <correct>, -c <correct>
	      The --correction setting controls the algorithm used during downsampling of the HDR ratio image data.  The default precorrect option
	      compensates  for	resampling  errors by adjusting the tone-mapped image to maximize the accuracy of the HDR result.  This option may
	      sometimes induce modest halo artifacts in the tone-mapped image at lower quality settings.  If the tone-mapped  (backwards  compati-
	      ble)  image  is  more  important than the HDR version, the postcorrect option may be used, instead.  To avoid all artifacts from HDR
	      resampling, specify the fullsamp option. This will result in slightly larger image files. Default: --correction=precorrect

       --alpha <a>, -a <a>; --beta <b>, -b <b>
	      The --alpha and --beta settings control color desaturation during tone-mapping, which will also permits  super-saturated	colors	to
	      pass  through  safely.   (See  the appendix of the paper by Ward and Simmons cited below for details.) Use --alpha < 1 to desaturate
	      colors and --beta > 1 to enhance color saturation contrast. Any input color space will be converted to the standard YCC color  space
	      of JPEG, based on the CCIR-709 (sRGB) primaries. Default: --alpha=1, --beta=1.
