The problem occurs due to a bug in the SunOS kernel for the +sparcstation. The patch given here is a workaround to avoid the problem +until Sun fixes the bug. + +To patch the imtool executable, login as iraf, then make a backup copy of +the imtool.e executable and patch the online one, as follows (be sure to +get the case of the ?X and ?W right): + + % cd $iraf/unix/bin.sparc + % cp imtool.e imtool.e.OLD + % + % adb -w imtool.e + 0xc2a0?X +* 0xc2a0: ac102018 + 0xc2a0?W0xac10200c +* 0xc2a0: 0xac102018 = 0xac10200c + $q + % + +In the sequence shown above, the lines marked * are adb output. If the old +value of location 0xc2a0 is not ac102018 (hex) as shown, then you have an +old or otherwise unusual version of IMTOOL and the patch should not be +applied. Once the executable has been patched, either copy the new executable +to /usr/bin/imtool (or wherever imtool lives on your system) or rerun the +INSTALL script in $hlib. + +The fix changes the rasterop used to draw the IMTOOL crosshair cursor from +a copy-source-to-destination to an xor-source-and-destination. This results +in a less visible cursor, but avoids the bug that leaves the scratches all +over the IMTOOL window. |
