Hi Ihr,

wie kann ich eigentlich in Perl Grafiken generieren? Ich möchte einfach eine Grafik 20x200 Pixel, in der in der Mitte ein Text $text steht. Vom Text möchte ich gerne Schriftart $schriftart und Schriftgröße $schriftgroesse sowie Schriftfarbe (HTML-Farbe, #000000) $schriftfarbe anpassen können.

Welche Module brauche ich dafür? Brauche ich überhaupt welche? Wenn ja, wo bekomme ich diese und wie installiere ich diese auf meinem Server? Bin nicht so der Linux-Profi, sorry.

Hat jemand einen Beispiel-Code wie ich das oben von mir genannte schaffen kann?

Viele Grüße & vielen Dank
Steffen

Schau dir mal die CPAN Module Image::Magick, GD und Imager an.
Die können all die Sachen, die Du benötigst...
In deren Doku findest Du auch genug Beispiele um Deine Anforderungen zu  realisieren.\n\n

z.b. mit gd

codebeispiel siehe synopsis des modules.
zu zeichenketten etc.:
http://search.cpan.org/author....Drawing

du musst vorher gd installiert haben. das geht je nach $DISTRO anders.

Hi Ihr,

danke sehr :-) Habe mich für GD entschieden und nun mal vesucht das Ganze zu installieren.

Habe mir also gd-2.0.15.tar.gz gedownloaded, auf meinem PC entpackt und per WinSCP in das Haupt-Verzeichnis meines Servers hochgeladen (ist es egal wo ich das hochlade?)

Dann habe ich mich per Putty SSH eingeloggt und bin ich das Verzeichnis gegangen.

Wollte nach Anleitung so installieren:

perl makefile.pl
make
make test
make install

Hat aber nicht funktioniert, gleich der erste Befehl nicht. Was mache ich falsch?

Muss ich das ganze in /usr/lib/perl5/site_perl/5.8/ hochladen und die Befehle dann ausführen? Oder ist der Fehler etwas anderes? Es gibt auch noch ein Unterverzeichnis "config" in dem Ordner des Teils. Wenn ich die Befehle da ausprobiere (z.B. make test), dann kommt "make: *** no rule to make target 'test'. Stop".

Viele Grüße und vielen Dank
Steffen\n\n

Hallo Steffen,

damit das GD Modul läuft, muß die GD Library auf dem Server installiert sein.
Und es wäre am sinnvollsten das Modul als root zu installieren.
Wenn es sich um einen Webserver handelt, auf dem Du nur Webspace hast, ist das natürlich nicht möglich, aber es kannsein, daß das Modul schon drauf ist. Probier es sonst einfach mal aus...

Hi,

bin als root eingelogt. Gd libary? wie installiere ich die?

Angeblich ist das GD schon drauf (sagten die Leute beim Support), wenn ich das in Perl aber nutzen will, dann kommt "can't locate ...". Also stimmt da irgendwas nicht. Die Frage ist nur was.

Habe es auch schon in SSH mit "perl -MCPAN -e shell" und dann "install GD;" probiert. Hat auch nicht funktioniert? Brauche ich zusätzlich noch andere Dinge, die ich vorher installieren muss? Freetype oder libdg? Wenn ja, wie mache ich das?

Viele Grüße
Steffen\n\n

poste, was du gemacht hast, und wie genau die fehlermeldungen lauten.
das perl-modul GD ist nur ein "aufsatz" auf libgd, um die bibliothek für perl benutzbar zu machen.

Wenn GD auf libgd aufsetzt, muss libgd doch vorhanden sein, wenn ich GD installieren will ...

Ein "locate libgd" ergab folgendes:

Quote
/usr/lib/libgd.so.4
/usr/lib/libgd.so.4.0.0
/usr/lib/libgdbm.a
/usr/lib/libgdbm.la
/usr/lib/libgdbm.so
/usr/lib/libgdbm.so.2
/usr/lib/libgdbm.so.2.0.0
/usr/lib/libgdk-1.2.so.0
/usr/lib/libgdk-1.2.so.0.9.1


Das heißt doch, dass libgd installiert ist, oder nicht?

Viele Grüße
Steffen\n\n

Das klingt nach einer defekten Datei... hmm :)

Vielleicht ist es die falsche libgd-Version? Oder stammt alles von der selben Distribution?
