Description
The jp2 files used by the Secondlife client, are actually j2k files. These can be encoded by image_to_j2k from openjpeg. The script checks for available tif-files in a root directory, and compresses those to j2k and renames them...
Usage
- Install OpenJPEG svn (if you have trouble compiling, you could try the binaries on their site)
svn co http://www.openjpeg.org/svn/trunk cd trunk mkdir bin cd bin cmake .. -DBUILD_EXAMPLES:BOOL=ON make make install
- Make sure that the binaries image_to_j2k and j2k_to_image can be executed from anywhere
- Put the code in a file named jpg2jp2.pl, and copy it to the directory where your jpg's are. Call the script:
perl jpg2jp2.pl
#!/usr/bin/perl -s -U
# textureprep.pl by Phrearch
use Cwd;
$dirs=1;
$files=0;
sub ScanDirectory{
my ($workdir) = shift;
my ($startdir) = &cwd; # keep track of where we began
chdir($workdir) or die "Unable to enter dir $workdir:$!\n";
opendir(DIR, ".") or die "Unable to open $workdir:$!\n";
my @names = readdir(DIR) or die "Unable to read $workdir:$!\n";
closedir(DIR);
foreach my $name (@names){
next if ($name eq ".");
next if ($name eq "..");
#What? a directory?!!
if (-d $name){
$dirs++; &ScanDirectory($name); next;
}
#We found one of those nasty textures
if (substr($name, -4) eq ".jpg") {
print "Processing $workdir\\$name..."; $rawname = substr $name, 0, -4; system("convert -format tga $rawname.jpg $rawname.tga &>/dev/null"); system("rm $name &>/dev/null"); system("image_to_j2k -i $rawname.tga -o $rawname.j2k -r 20,10,1 &>/dev/null"); system("mv $rawname.j2k $rawname.jp2 &>/dev/null"); system("rm $rawname.tga &>/dev/null"); print "done!\n"; $files++;
}
chdir($startdir) or
die "Unable to change to dir $startdir:$!\n";
}
}
&ScanDirectory(".");
print "\nDirectories scanned:$dirs\nFiles processed:$files\n";
