gscan2pdf is a GUI to ease the process of producing PDFs from scanned documents. You scan in one or several pages and create a PDF of selected pages. Scanning is handled with SANE via scanimage. PDF conversion is done by PDF::API2. Perl is used for portability and ease of programming, with gtk2-perl for the GUI.
SANE stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware (flatbed scanner, handheld scanner, video and still cameras, framegrabbers, etc.). The SANE standard is public domain and its discussion and development are open to everybody. The source code is written for UNIX (including Linux) and is available under the GPL, but commercial applications and backends are welcome. The package contains the libraries, net support, and scanimage. The X frontends xscanimage and xcam can be found in sane-frontends.
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.
This package contains frontends to SANE ("Scanner Access Now Easy"), including xscanimage, xcam, and scanadf. Xscanimage is a GTK-based application for scanning images that can also be used as a GIMP-plugin. Xcam is used to get images from cameras supported by SANE. Scanadf is a command line frontend especially suited for scanners equipped with automatic document feeders (ADF).
ExactScan is a versatile document capture application for home offices and workgroups. It is designed from the ground up for high-speed document scanners and can easily handle hundreds of images per minute, including duplex scans. Included functionality reaches from managing, sorting, and editing singles pages to writing multi- as well as single-page PDF files including JPEG compression and TIFF, JPEG, JPEG2000, and PNG bitmap files. ExactScan allows performing state of the art image processing including automatic cropping, deskewing, dynamic thresholding for perfect black and white documents, and descreening print rasters.
HPLIP (HP Linux Imaging and Printing) is a complete single and multi-function printing device connectivity solution for users of Linux. Supported features include a toolbox with status and maintenance functions, scanning, a CUPS backend that supports bidirectional I/O, and photo card unloading. It includes HPIJS 2.x and supports over 1000 HP printer models including Deskjet, Business Inkjet, Photosmart, Business Inkjet, PSC, Officejet, Mono/Color LaserJet, and LaserJet Multifunction Peripheral (MFP).
Multi Threaded TCP Port Scanner allows you to scan 65535 TCP ports on an IP address. You can specify how many threads to run and the timeout. Furthermore, it will tell you the MAC address of the target and the services that are running. You can scan IP addresses on your network and find out which open ports you have.
The HP OfficeJet Linux driver provides printing, scanning, and photo-card access support for most Hewlett-Packard multi-function peripherals connected to a parallel port, USB port, or LAN via selected HP JetDirect print servers. Additional applications are provided to view the contents of the front-panel LCD and to access other control and status features of the device.
