Engauge Digitizer is digitizing software that converts an image showing a graph or map into numbers. The image file can come from a scanner, digital camera, or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet. Highlights for beginners include an intuitive interface and extensive context-sensitive documentation. Highlights for experts include compensation for image distortion, cartesian and polar coordinates, linear and logarithmic coordinates, automatic scanning, graphical previews, and browser help.
JCap is a Java application for adding captions and descriptions to your digital photograph collection and includes a search dialog for finding photos later. It is completely self-contained; it doesn't require a separate database application or Web server to run. Captions, descriptions, and keywords are stored in plain text files in the same folder as the images they describe and can be read by any application that can read text files. The primary goals are: to help you find photos later, to help share photos with others, and to be able to read photo captions and descriptions thirty years from now on whatever computer you happen to have at the time.
Morena is a Java framework that allows a Java program to acquire an image from a scanner or camera. To communicate with the hardware, it uses standard interfaces: Twain for MS Windows and Mac OS X and Sane for a number of Unix platforms (AIX, BeOS, Darwin, FreeBSD, HP-UX, Linux, NetBSD, OpenBSD, OS2, Solaris, Unixware).
Exiv2 is a C++ library and a command line utility for managing image metadata. It provides fast and easy read and write access to the Exif, IPTC, and XMP metadata of images in many formats. The Exiv2 command line utility prints Exif, IPTC, and XMP metadata including Makernote tags in various formats, adjusts Exif timestamps, renames images according to the Exif timestamp, extracts and inserts Exif, IPTC, and XMP metadata and JPEG comments, or deletes the thumbnail or a specific type of metadata from an image.
pHoToMoLo is a toolset for managing JPEG images in JFIF or Exif format. Photomolo generates a static HTML 4.01- and CSS 1-based multi-resolution image gallery for a directory tree containing images. Exifiron losslessly compresses and corrects the orientation of Exif JPEG images. Jpegnail removes or embeds thumbnails. Jpegcom lets you edit embedded image comments using any text editor and image viewer. A shell script frontend for Exifiron is included for copying images from removable storage, such as USB or Compact Flash.
