Free read software for linux

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.

Spreadsheet::Read enables reading the data from a spreadsheet.

Spreadsheet::Read tries to transparantly read *any* spreadsheet and return its content in a universal manner independent of the parsing module that does the actual spreadsheet scanning.

For OpenOffice this module uses Spreadsheet::ReadSXC

For Excel this module uses Spreadsheet::ParseExcel

For CSV this module uses Text::CSV_XS

For SquirrelCalc there is a very simplistic built-in parser

Read Local Lyrics is a little Python script works as a lyrics plugin.

If to some audio file, a corresponding ".txt" file can be found in the same folder, this is taken as the lyrics of the song.

Joystick is a utility to read commands from joystick and send to BMPx via DBUS. Commands are configured via .ini file. Should be easy to work with other DBUS-consumers.
