File: JX100Input.zip Author: Edmund Vermeulen Release: 1.0.0 (July 25th, 1997) Compatibility: PR Location: contrib/libraries Description: Sharp JX-100 colour scanner input handler. Notes: Capture handler for datatypes library. Freeware. JX100Input is a capture handler for the datatypes library by Jon Watte. It allows you to make colour scans with a Sharp JX-100 serial scanner from within any application that supports the data capture interface of the datatypes library (e.g. DTPicView). Features - Support for both DATA_BITMAP and DATA_MEDIA output formats. - DATA_MEDIA lets the user see the scan process in real time. - Config view lets the user enter the serial port name. - Capture view can display a (grayscale) preview scan. - User can select the area and resolution to scan. Installation Install it by copying the file 'JX100Input' to the directory '/boot/home/config/add-ons/Datatypes'. You must have version 1.6.3 (or higher) of libdatatypes.so installed in '/boot/home/config/lib' to be able to use it. Usage First you need to enter the serial port name where the Sharp JX-100 is connected. The scanner is driven at 115200 bps, so you need a serial port that supports that. On the BeBox you should use either 'serial1' or 'serial2'. 'serial2' is the default. When the capture view is displayed, you will notice the large preview area. This allows you to select the exact area that you want to scan. Press the 'Scan Preview' button to display a grayscale preview. You can set the scan area by entering the preferred values by hand, or by simply adjusting the red selection rectangle with the mouse. Once you have set the correct scan area and DPI resolution, you can press the 'Start Scan' button. This will start the actual capture process that delivers bitmap data to the application that is running JX100Input. When the scanning process is in progress, you may abort it by pressing the 'Stop Scan' button. This may take a while. Tips In DTPicView, switch on the setting 'Media Stream First' before starting the capture. That way, you will be able to watch the scan as it takes place. You can then see the separate colour components coming in to build the final image. Really neat. Also, you will probably want to switch on the 'No Dithering' option on 8-bit screens. Otherwise you will lose the original 32-bit data. DTPicView also has an option to make the image brighter through gamma correction. This is often necessary when the scan is a bit dark.
