Image Database

Image Database

[Jessica Holle]

I've some questions about the Image Database.
I found no answers in the xfigure.pdf.

Can I generate the xml file automaticly?
I can use xmltools --dir --pattern=/home/tralal/*.jpg
--output=tralala.xml
but then in the xml file doesn't stad figure, there is file. so this
doesn't work I think.

Must everything be in the same folder? the xmlfile, the images and
my document I'm writing?
Or can I specify a directory in the xmlfile? So that the images can
be on an other folder than the xmlfile?

Must the xmlfile be in the same directory than my document?

Humble, I do not know what xmltools all can do. I use a perl-sript to 
generate the xml-file. - Please have a look into the attached file 
make-xml.pl

Normally I prepare a directory with the figures. The xml-file is then 
generated and compiled. The resulting figure-databse I transfer then to 
the directory where the tex files reside.

I hope this will help you.
Kind regards

## Prepare an XML-file for the preparation of a figure-database with TeX

## XML-file header information:

$Librarylanguage = "en";
$Organization = "Willi";
$Project = "Restauratie";
$Product = "Restauratie-cursus ";
$Comment = "Figure database";
$CopyRight = "WE" ;


## Variables

$Filename = "";
$FileextensionA = "pdf";
$FileextensionB = "png";
#~ $FileextensionC = "1";
$Filedate = "";
$Filetimestamp ;
$Filesize= "";
$Globstring = "*." . $FileextensionA;
$Outfile = ">Figure-lib.xml";

## Date
($Second, $Minute, $Hour, $DayOfMonth, $Month, $Year, $WeekDay, $DayOfYear, $IsDST) = localtime(time);
$RealMonth = $Month +1 ;
$RealYear  = $Year + 1900 ;

printf ('%02d.%02d.%04d', $DayOfMonth,$RealMonth,$RealYear);
print   "\n";

## Open the XML-file for writing:
open(OUTFILE, $Outfile);

## Print XML-file header:
Header();

## Collect Figure files into an list:

@Files = glob($Globstring);
$Globstring = "*." . $FileextensionB;
@MoreFiles = glob($Globstring);
push(@Files, @MoreFiles);
#~ $Globstring = "*." . $FileextensionC;
#~ @MoreFiles = glob($Globstring);
#~ push(@Files, @MoreFiles);

## Work on each filename:

foreach $Filename (@Files) {

    #~ $exifinfo = `identify -verbose -format "%[EXIF:*]" $Filename`;
    #~ chomp($exifinfo);
    #~ if(length($exifinfo) < 2){
        #~ $Filetimestamp = (-C $Filename) ;
        #~ $Filedatestamp = time - $Filetimestamp ;
        #~ ($Second, $Minute, $Hour, $DayOfMonth, $Month, $Year, $WeekDay, $DayOfYear, $IsDST) = localtime($Filedatestamp);
        #~ $RealMonth = $Month +1 ;
        #~ $RealYear  = $Year + 1900 ;
        #~ $FileDate = $DayOfMonth . "." . $RealMonth . "." . $RealYear ;
    #~ }
    #~ else {
        #~ @exiflines = split(/\n/,$exifinfo);
        #~ foreach $exifline (@exiflines){
        #~ ($exifHeader,$exifData) = split(/=/,$exifline,2);
        #~ if($exifHeader eq "DateTimeOriginal"){
            #~ $FileDate = substr($exifData,8,2) . "." . substr($exifData,5,2) . "." . substr($exifData,0,4);
        #~ }
        #~ }
    #~ }
    $Filesize = (-s $Filename) ;
    if ($Filesize > 1024){
        $Filesize = int($Filesize / 1024) . "k";
	}
## Determine first part	of filename -> label in figure library
($Label,$Suffix) = split (/\./,$Filename) ;

## Print the XMLblock for the actual figurefile:

Printfigureblock();
}

print OUTFILE  "</figurelibrary>";

close(OUTFILE);

## End of main programme.

if you install cont-exa.zip, you can say:

rslibtool --add *.pdf

(other options are --delete --sort etc; undocumented)

should be possible

no, you can define paths with 

\usepath[...]
\useeubpath[...]
\setupexternalfigures[directory=...]

support for figure databases will move to rlxtools; although not yet documented, context supports on the fly conversions with caching (so that it only happens when needed) based on resource logs 

more about that later
