Libqrencode is a C library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and is highly robustness. Libqrencode supports QR Code model 2, described in JIS (Japanese Industrial Standards) X0510:2004 or ISO/IEC 18004. Currently the following features are not supported: * ECI and FNC1 mode * QR Code model 1

This package will read and write TIFF format images and return them as a pixmap object. Because the resulting object can be very large for even modestly sized TIFF images, images can be reduced as they are read for improved performance. This package is a wrapper around libtiff (www.libtiff.org), on which it depends (i.e. the libtiff shared library must be on your PATH for the binary to work, and tiffio.h must be on your system to build the package from source). By using libtiff's highlevel TIFFReadRGBAImage function, this package inherently support a wide range of image formats and compression schemes. This package also provides an implementation of the Ridler Autothresholding algorithm for easy generation of binary masks.

ShowImage is a simple KDE based image viewer using the maximum space inside its window without cluttering the window with menubar, toolbar or statusbar.

This is the Eye of Gnome, a GNOME 2 image viewer and cataloging application. It provides inline image viewing support for nautilus.

MetaCam is a utility to read and decode meta-information from digital camera images with EXIF information. In addition to the standard EXIF fields, MetaCam also supports vendor-specific extensions from Nikon, Olympus, Canon and Casio.

Metapixel is a photomosaic generator. It can generate classical photomosaics, in which the source image is viewed as a matrix of equally sized rectangles for each of which a matching image is substituted, as well as collage-style photomosaics, where the images are placed at arbitrary positions in the source image, not aligned to a matrix.

GNU Ocrad is an OCR (Optical Character Recognition) program implemented as a filter and based on a feature extraction method. It reads a bitmap image in pbm format and outputs text in ISO-8859-1 (Latin-1) charset. Also includes a layout analyser able to separate the columns or blocks of text normally found on printed pages. It can be used as a stand-alone console application, or as a backend to other programs.

Acme::Steganography::Image::Png - hide data (badly) in Png images

Tag replacement framework for graphics/p5-CAD-Drawing.

Perl helper class for implementing the Google Chart Tools Datasource Protocol. The Google Visualization API is a nifty bit of kit for generating pretty pictures from your data. By design it has a fair amount of Google-cruft, such as non-standard JSON and stuffing configuration options in to a single CGI query parameter. Data::Google::Visualization::DataTable takes care of preparing data for the API.
