Biometrisches Paßphoto mit GIMP selbst erstellen und im Supermarkt drucken leicht gemacht
Zunächst muß das Paßphoto den biometrischen Richtlinien (1) entsprechen. Diese können mittels der beigefügten Schablone und GIMP leicht erfüllt werden. Dann kann das Paßphoto in im Supermarkt gängige Sofortdruckformate (9x13, 10x15, 11x17, 13x18, 20x30) umgewandelt werden. Angefügtes Bild in GIMP öffnen. Gewünschtes Paßphoto als neue Ebene öffnen. Paßphoto-Ebene so skalieren und verschieben, daß Gesicht in die Maske passt. Schablonen-Ebene unsichtbar machen und Paßphoto exportieren (Name muss sein: passphoto.png). Beigefügtes Perl Skript speichern, ausführbar machen und loslassen. NB: ImageMagick muß installiert sein. Die erzeugten Bilder im Supermarkt ausdrucken. ########### Beginn: Perl Skript ########### #!/usr/bin/perl my $passphoto = “passphoto.png”; my $basename = $passphoto; $basename =~ s/.png//; my %format = ( “9x13” => { “width” => 1535, “height” => 1053, “nrow” => 2, “ncol” => 3}, “10x15” => { “height” => 1181, “width” => 1772, “nrow” => 2, “ncol” => 4}, “11x17” => { “height” => 1299, “width” => 2008, “nrow” => 2, “ncol” => 4}, “13x18” => { “height” => 1535, “width” => 2126, “nrow” => 2, “ncol” => 5}, “20x30” => { “height” => 2362, “width” => 3543, “nrow” => 4, “ncol” => 8}, ); for my $f (keys %format) { print “Make photos for $f\n”; my $img = $basename.”_”.$f.”.jpg”; my $cmd = “montage -background red -geometry 414x532+2+2 -tile “; $img = $img.$format{$f}{“ncol”}.”x”.$format{$f}{“nrow”}; $cmd = $cmd.” “.$passphoto foreach (0..$format{$f}{“ncol”}*$format{$f}{“nrow”}); $cmd = $cmd.” png:- | convert -resize “.$format{$f}{“width”}.”x”.$format{$f}{“height”}.’>’; $cmd = $cmd.” -size “; $cmd = $cmd.$format{$f}{“width”}.”x”.$format{$f}{“height”}.” xc:red png:- -gravity “; $cmd = $cmd.” center -composite “.$img; $cmd; } ########### Ende: Perl Skript ########### (1) Biometrische Richtlinien für Paßphotos:http://www.bundesdruckerei.de/de/service/service_buerger/buerger_persdok/persdok_epassMstr.html …

Lattice Defects
Stacking faults are colored in red, partial dislocations and the surfaces are colored in gray. The nucleation of plasticity is homogenous. An amorphous blob of defective particles is nucleated in the region of the maximal stress. Later a stacking fault is nucleated and cross glide sets in. …
