ExifTool is a Perl module with an included command-line application for reading and writing meta information in image, audio, and video files. It reads EXIF, GPS, IPTC, XMP, JFIF, MakerNotes, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP, and ID3 meta information from JPG, JP2, TIFF, GIF, PNG, MNG, JNG, MIFF, EPS, PS, AI, PDF, PSD, BMP, THM, CRW, CR2, MRW, NEF, PEF, ORF, DNG, and many other types of images. ExifTool also extracts information from the maker notes of many digital cameras by various manufacturers including Canon, Casio, FujiFilm, GE, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Nikon, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon, and Sony.
This Perl extension allows you to extract meta information from various types of image files.
Image::Size is a library based on the image-sizing code in the wwwimagesize script, a tool that analyzes HTML files and adds HEIGHT and WIDTH tags to IMG directives. Image::Size has generalized that code to return a raw (X, Y) pair, and included wrappers to pre-format that output into either HTML or a set of attribute pairs suitable for the CGI.pm library by Lincoln Stein. Currently, Image::Size can size images in XPM, XBM, GIF, JPEG, PNG, MNG, TIFF, the PPM family of formats (PPM/PGM/PBM) and if Image::Magick is installed, the formats supported by it.
This class module provides basic load, manipulate and save functionality for the xbm file format. It inherits from Image::Base which provides additional manipulation functionality.
This class module provides basic load, manipulate and save functionality for the xpm file format. It inherits from Image::Base which provides additional manipulation functionality.
Loading Import::Into creates a global method import::into which you can call on any package to import it into another package.
This module converts between JSON (JavaScript Object Notation) and Perl data structure into each other. For JSON, see http://www.crockford.com/JSON/.
JSON::XS is the fastest and most proper JSON module on CPAN. It is written by Marc Lehmann in C, so must be compiled and installed in the used environment. JSON::PP is a pure-Perl module and is compatible with JSON::XS.
This module converts Perl data structures to JSON and vice versa. Its primary goal is to be correct and its secondary goal is to be fast. To reach the latter goal it was written in C.
This module provides functions for handling media (also known as MIME) types and encodings. The mapping from file extensions to media types is defined by the media.types file. If the ~/.media.types file exists it is used instead. For backwards compatibility we will also look for ~/.mime.types.
