Modul für bildbearbeitung - einige formate in jpg

[Siechfred]

Hallo alex.

kann man mit dem modul GD diese formate "JPEG BMP GIF TIFF PNG" einfach in das JPG-Format umwandeln?

Was verstehst du an der Dokumentation nicht?:
http://search.cpan.org/~lds/GD-2.12/GD.pm#Object_Constructors:_Creating_Images
"Alternatively, you may create a GD::Image object based on an existing image by providing an open filehandle, a filename, or the image data itself. The image formats automatically recognized and accepted are: PNG, JPEG, XPM and GD2. Other formats, including WBMP, and GD version 1, cannot be recognized automatically at this time."

Btw, JPEG und JPG ist das gleiche.

Freundschaft!
