KScannerButtons is a daemon plus an optional KDE frontend for monitoring your scanner buttons so that actions can be taken in response to button presses. It's composed of a daemon (sanebuttond), a frontend that will display an icon in the systray, and a dialog box to configure and launch the daemon. It is based on the button monitoring capabilities found in some SANE backends. It has been tested with the avision backend and an HP 5300C scanner. The frontend requires Kommander (kde-webdev).
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.
PDFView is a very simple program to view PDF files. on contrast to Preview, the main window will open up maximized, and with the drawer hidden by default. When you toggle the drawer, the main window will resize just enough to show it, and maximize again when you hide it. The zoom level will be as big as possible to make the document fit, making it as easy to read as possible.
Graidle (Graph aid) is a Web application for creating charts. It can be used to generate several types of graphical diagrams. It has classes specialized in generating histograms (also horizontal), spider graphs, pie charts, and line (also filled) charts. Several visual aspects may be customized, such as colors, font dimensions, labels, and axes. The diagrams are generated as true color images using PHP and GD library functions, and can be displayed as the current script output or saved to a file in the PNG format.
