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

NAME

       rdjpgcom - display text comments from a JPEG file

SYNOPSIS

       rdjpgcom [-verbose] [filename]

DESCRIPTION

       rdjpgcom  reads the named JPEG or JFIF file, or the standard input if no file is named, and displays any text comments found in the file on
       the standard output.

       The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file. Although the standard does not actually  define  the  intended
       function  of COM blocks, they are widely used to hold user-supplied text strings. This enables you to add annotations, titles, index terms,
       and so on to your JPEG files, and later retrieve the COM blocks as text. COM blocks do not interfere with the  image  stored  in  the  JPEG
       file. The maximum size of a COM block is 64K, but you can have many COM blocks in one JPEG file.

OPTIONS

       The following options are supported:

       -verbose        Causes rdjpgcom to also display the JPEG image dimensions.

OPERANDS

       The following operands are supported:

       filename        The name of the JPEG file that contains text comments.

EXTENDED DESCRIPTION

       rdjpgcom does not depend on the IJG JPEG library. The rdjpgcom source code is intended to illustrate the minimum amount of code required to
       parse a JPEG file header correctly.

       In -verbose mode, rdjpgcom also attempts to display the contents of any "APP12" markers as text. Some digital cameras produce APP12 markers
       that contain useful textual information. You can also modify the source code to display other APPn marker types.
