Anyway, I can't commit this because I'm out of town, but if anyone

try it, you need to change lines in procedure GmAnim::main (module
animate.tcl). Replace the commented lines with the uncommented
lines below.
foreach line $reglist {
set line [string trim $line]
set key [lindex [split $line "="] 0]
switch $key {
nsres {set oldres1 [lindex [split $line "="] 1]}
ewres {set oldres2 [lindex [split $line "="] 1]}
rows {set vrows [lindex [split $line "="] 1]}
cols {set vcols [lindex [split $line "="] 1]}
}
}
# regexp {nsres= *([0-9]+)} $region dummy oldres1
# regexp {ewres= *([0-9]+)} $region dummy oldres2
# regexp {rows= *([0-9]+)} $region dummy vrows
# regexp {cols= *([0-9]+)} $region dummy vcols
Michael,
Thanks for the email. I made the following changes but ended up with
a new error. I might have altered the wrong file. Here is what I tried.
From the file ~/src_intel/grass-6.3.cvs/gui/tcltk/gis.m/animate.tcl
# set initial canvas geometry to match region
if {[catch {set region [exec g.region -ugp]} error]} {
Gm::errmsg $error
}
# regexp {nsres= *([0-9]+)} $region dummy oldres1
# regexp {ewres= *([0-9]+)} $region dummy oldres2
# regexp {rows= *([0-9]+)} $region dummy vrows
# regexp {cols= *([0-9]+)} $region dummy vcols
foreach line $reglist {
set line [string trim $line]
set key [lindex [split $line "="] 0]
switch $key {
nsres {set oldres1 [lindex [split $line "="] 1]}
ewres {set oldres2 [lindex [split $line "="] 1]}
rows {set vrows [lindex [split $line "="] 1]}
cols {set vcols [lindex [split $line "="] 1]}
}
}
New error when startring up GmAnim.

Perhaps this is not what you intended?
