Hallo zusammen,
wie kann ich mit möglichst wenig Aufwand und wenn möglich ohne externe Module eine GIF, JPEG oder ZIP-Datei über PERL ausgeben?
Wie kann ich bei GIF/JPEG-Bildern die Bildgröße in Pixeln feststellen? Kann ich diese sogar verändern?
MfG,
Daniel T.

Hallo,
»» wie kann ich mit möglichst wenig Aufwand und wenn möglich ohne externe Module eine GIF, JPEG oder ZIP-Datei über PERL ausgeben?
Indem du den richtigen Content-type ausgibst zB image/gif. Danach gibst du das Bild in der Standardausgabe aus.
Du musst vor der Ausgabe noch binmode STDOUT; setzen, und danach.
print STDOUT $bild;

Ja, am besten mit den Modulen Image::Magick und Image::Size. Zumindest verwende ich immer diese Module, wenn ich aus einem Haufen Bildern Thumpnails erzeugen will.

Alles klar, vielen Dank!!!
Ich habe den Ausgabekanal nicht angegeben.
Dass bei der Übertragung eines ZIP-Files nicht der eigentliche Name steht, sondern der Name des Scripts ist normal, denke ich!?
Das mit dem Image-Modul probiere ich mal aus.
MfG

Wie machst Du das bei html?
Richtig:
print "Content-type: text/html\n\n";
Du gibst also den entsprechenden content-type aus.
