Filed on [Indigo]JasmineScanInfo.bravo and [IVY]Jasmine.press.This is a quick reference guide to the Jasmine Scan program. It is not meant as a tutorial, butrather as a reference to a user (or patient/curious beginner) of Scan.How To Get Started:There are two versions of Scan; one which runs on Altos and one which runs on D0s (Dolphins).You should contact your local support organization if you don't already have a Mesa 6.0environment needed to run Scan. For Altos, retrieve[IVY]Jasmine>Alto>Scan.bcd, and for D0s, retrieve[IVY]Jasmine>D0>Scan.bcd. D0 users are required to have[IVY]InitialAlto.eb!46 loaded as resident microcode.Support Issues:This release of Scan is mostly a Mesa 6 conversion. It fixes a couple of bugs and has betteroutput and calibration routines. Most old bugs are still there. (Any volunteers to fix problemsor add features will be warmly welcomed). If you have trouble, send a message to. I will be happy to provide consulting for people who have specificapplications. My role in maintaining this software is that of a "placeholder", with theexpectation of "full-fledged" Jasmine support from ISL as the laboratory develops.Sample Session:To start Scan, type "Scan" to the alto executive (this presupposes that you have a workingJasmine scanner attached, and the correct version of Scan.bcd loaded onto a Mesa 6 disk alongwith the correct microcode (if you're running on a D0).The Jasmine retains its calibration until powered off, so if the scanner has not been calibratedsince being powered on, type "c" when Scan first starts. You should insert the best availablewhite sheet of paper (the back of a sheet with print on it is a poor choice) into the scanner inanswer to the prompt.You may now type "n" to insert a new page to scan. The paper should be inserted face down.The "h" command will cause Scan to input the page; the space bar will stop scanning at anytime.The "z" Zoom command, along with changing the threshold values for black and white, and thetime for integration ("b", "w", and "t") allow the user to adjust the scan for the best picture.Often the contrast on black and white material can be increased with black and whitethreshold settings around 50 and 190 respectively, but you should experiment for the bestvalues. The "o" output command allows the result to be dumped to an ais file. Type the "q"command to exit Scan.Command Summary:?Displays current values for parameters Black, White, XStart, XLen, YStart, YLen!Turns the controller on or off (toggle)bSets black threshold-- prompts for a value between 0 and 255cCalibrates the Jasmine-- expects to see a white sheet of paperdSets Delay parametereErase the screenfAdvance paper-- prompts for number of stepshHalftone sample inputiInitialise RAMlSets length of scannEjects old page and accepts new page input bpL _&: ]F Z3 ZqNp WM UE Ty RN; Qqs$t O8 Lk eLqN p I%8 H6a F*' E-C C?
