Open a Feed Reader for any OPML Autodiscovery enabled page. You can choose between Optimal OPML browser and Grazr.

PHP feed finder is a PHP class that finds all the URLs for all RSS and ATOM feeds that appear on a given as well as OPML outline documents from a Web page.
The project will convert any relative links that are found into absolute links. The only required input is the URL of the Web page to be scanned for links.
Enhancements:
- ATOM feed links and OPML outline documents are now retrieved by the class, in addition to RSS links.

zFeeder provides a RSS feed reader (aggregator) to integrate news on a Website.
zFeeder is a simple, customizable, RSS feed reader (aggregator) to integrate news from syndication pages on your Website, wapsite, or intranet.

dotBook reader is a reader for HTML books in .jar and .zip files.

The dotBook application will be a book reader that can download, display and cache books in a special JAR file format.

The format will allow digital signatures with PGP and allow books to have chapters and paragraphs that can be found conveniently from within the application but will link sources outside books by opening the default web browser. Book pages will be HTML pages with some restrictions.

Design Goals

The goal is to have an XML descriptor format to be stored outside the book (JAR file) and an XML content format to be stored inside the JAR file. A compound format that allows to combine descriptor, JAR file and signatures in a single file is being considered. Reading the descriptor should be very easy and not require to read the JAR file, so the JAR file will possibly be compressed and appended to the uncompressed descriptor.

The book layout will honor CSS PrintLayouts.

The XML content will allow for imprints following an independent specification for XML imprints, factored out from the esp.nongnu.org project.

The dotBook editor will allow to edit a limited subset of the MediaWiki syntax and a subset of HTML.

The format is intended to be useful on e-Paper devices that can hibernate between turning pages. A sequential page order will be encouraged, while still allowing to set anchors and links inside pages. Animated content will be discouraged: It will probably only be animated on user request. That means all animated images will be replaced by empty boxes with the text "Animation : [play]" inside, if no still image is provided to take the place.

CGIFeed is a CGI program that reads news feeds (via XML/RDF/RSS) and prepares HTML pages for them.

You can enter new feeds through the Web page, and edit the name and update interval for each feed.

gfeed is an RSS/RDF feed reader for Linux and Gtk+-2.0. gfeed project is designed to be a simple yet highly customizeable reader, not an agggregater, which means it is designed for easy integration into a desktop.
Main features:
- Customizable "feed" files that describe a feed
- Full support for transparency(native to the app) under X.org >= 6.8
- Automatic updating of feeds based on an interval defined in the feed file
- Customizeable Background and Foreground colors

Imagero Reader is a Java library for reading image files. Supported file types include BMP, GIF, TIFF, PNG, JNG, MNG, JPEG (including 12-bit grey), PSD, PBM, PGM, PPM, TGA, EPS, EPSI, and EPSF.
The following RAW file types are also supported, at least partially: MRW, CRW, NEF, DCR, and DNG. It can read thumbnails, read metadata (IPTC, EXIF, and XMP), edit metadata, get image width and height, get the number of images contained in a file, define an area to read, add a ProgressListener, choose an image channel to read, set a scale factor, set subsampling (JPEG only), and read an image (or channel) directly into an array.
Supported file types are:
- BMP 1, 4, 8, 16, 24 and 32 bit uncompressed; 4 and 8 bit compressed
- GIF
- TIFF 1, 4, 8, 16, 32, 48 and 64 bit per pixel; bilevel, grayscale, palette, RGB, CMYC, Cie Lab, YCrCb color spaces; CCIT1D, G3, G4, ZIP, JPEG, LZW and PackBits compression
- PNG, JNG, MNG
- JPEG inclusive CMYC and 12-bit grey
- PSD
- PBM, PGM, PPM
- TGA
- read embedded images from EPS, EPSI, EPSF
Supported RAW files:
- MRW
- CRW*, CR2*, THM
- NEF*
- DCR*
- DNG*
- Full resolution image cant be yet read, but thumbnail, preview and metadata can be read.
Main features:
- read thumbnails
- read/edit metadata
- any metadata contained in ImageResourceBlock ( PSD, JPEG, TIFF) and ImageFileDirectrory entry ( TIFF, NEF, DNG, DCR) can be edited full control over JPEG metadata
- get image width and height
- get number of images, contained in file
- define an area to read
- add a ProgressListener
- estimate JPEG compression/quality
- read an image channel
- set a scale factor
- set subsampling (JPEG only)
- read an image (or channel) directly into an array
- easy IPTC handling with IPTCParser and IPTCEditor
Whats New in 1.9.6 Stable Release:
- The EPS parser was partially rewritten and made more generic and easy to use.
- It may be used now to parse nearly every kind of data (as a programmable parser).
- Thumbnails are read from AI (Illustrator) files.
- Disc based image caching was implemented (but is beta).
- New methods were added to TiffUtils: insert IFDEntry, remove IFDEntry, and create and insert IFDEntry with IPTC data.
- Two utility classes were added for creating and adding EXIF and GPS data to TIFF images.
- An important bug in XMPApp1 concerning wrong field length was fixed.
Whats New in 2.0.0 RC3 Development Release:
- It is possible to write TIFF images now. TiffWriter can currently write RGB, ARGB, CMYK, and grayscale (8 bit) images.
- Supported compression schemes are uncompressed, PackBits, and ZIP.
- Bugfixes were made.
