Filed on [IVY]JasmineScanInfo.bravo and[IVY]Jasmine>JasmineScanInfo.bravo.This is a quick reference guide to the Jasmine Scan program. It is notmeant as a tutorial, but rather as a reference to a user (or patient/curiousbeginner) of Scan.How To Get Started:There are two versions of Scan; one which runs on Altos and one whichruns on D0s (Dolphins). You should contact your local supportorganization if you don't already have a Mesa 6.0 environment needed torun Scan. For Altos, retrieve [IVY]Jasmine>Alto>Scan.bcd,and for D0s, retrieve [IVY]Jasmine>D0>Scan.bcd. D0 usersare required to have [IVY]InitialAlto.eb!46 loaded as residentmicrocode.Support Issues:This release of Scan is mostly a Mesa 6 conversion. It fixes a couple of bugsand has better output and calibration routines. Most old bugs are still there.(Any volunteers to fix problems or add features will be warmly welcomed).If you have trouble, send a message to . I will be happy toprovide consulting for people who have specific applications. My role inmaintaining this software is that of a "placeholder", with the expectation 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 youhave a working Jasmine scanner attached, and the correct version ofScan.bcd loaded onto a Mesa 6 disk along with the correct microcode (ifyou're running on a D0).The Jasmine retains its calibration until powered off, so if the scanner hasnot been calibrated since being powered on, type "c" when Scan first starts.You should insert the best available white sheet of paper (the back of asheet with print on it is a poor choice) into the scanner in answer to theprompt.You may now type "n" to insert a new page to scan. The paper should beinserted face down. The "h" command will cause Scan to input the page;the space bar will stop scanning at any time. ap0 _- []3 YL"* W; RSq{p N 8 L" J- HD F.

Often the contrast on black andwhite material can be increased with black and white threshold settingsaround 50 and 190 respectively, but you should experiment for the bestvalues. The "o" output command allows the result to be dumped to an aisfile. 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 inputoOutput to file-- expects filename of form .aisqQuit Scan.bcdrReverse paper-- prompts for number of stepssSet skip counttSet time for integration-- initially 656 (38 uSec ticks)wSet white threshold-- prompts for a value between 0 and 255xFollowed by "l" or "s", sets XLen or XStart parametersyFollowed by "l" or "s", sets YLen or YStart parameterszZoom halftone mode-- draw rectangle with mouse red, yellow to moveorigin, and blue to invokeNfcr ap 6 _K ]n$* []* YL= W;) U*) PQq{p LB J H' F< D> B @~ >m+ <\ :K 89 6(* 44 2 /+ - +8 ); '6 %6 #B !}R $?H TIMESROMAN TIMESROMANCLASSIC 8 j/  q jasmine.bravoOrrJuly 30, 1982 1:18 PM
