fax2png extracts a specified page from a 1-bit black and white TIFF image, such as a fax, and efficiently converts it to PNG format without the performance overhead of netpbm-based solutions. Antialiasing is supported to produce attractive reductions to typical Web browser widths. 90-degree-interval rotations and flips are also supported.
gd is a library for creating and reading PNG, JPEG, GIF, WBMP, and XPM images. It has many features and can be used in scripts (e.g. PHP, Perl, Ruby, Lua, and Python) for dynamic image generation. PHP users should note that PHP 4.3.x includes its own distribution of gd, which is currently the best choice for PHP applications.
smtp-after-popd briefly authorizes outgoing SMTP message sending via Postfix for addresses that have recently been authorized to receive mail by either ipop3d or vm-pop3d. The timeout and all other parameters are easily adjusted. It is written in Perl and works by parsing syslogd-produced mail log files efficiently in real time, so that no modifications to ipop3d or vm-pop3d are required. It is CPU friendly and easy to modify.
webthumb creates a PPM format image of the first screen of a Web page and writes this image to standard output. This is done using the Xvfb virtual framebuffer X server, which provides an environment for the Mozilla Web browser. To minimize CPU impact, the Xvfb and mozilla processes are kept resident in memory and reused by future invocations of webthumb.
