Um das Test Bild zu erstellen, bitten den Code hier ExtractTestImage.bas in den vorher gleichen Ordner erstellen, kompilieren und ausführen. Es sollte nun das Test Bild "Panda_800x800.bmp" erstellt worden sein (NUR FÜR WINDOWS!)!
Jetzt Rutt_Etra_Izer_FX.bas starten.

Da es hier ja naturbedingt immer recht wenig Rückmeldung gibt, will ich mich doch mal rühren: Da sind immer wieder sehr hübsche Sachen dabei, und auch der Wurm gefällt mir wieder sehr gut!

Danke für dein Feedback.
Wenn ich mich anhand der Rückmeldungen richten würde, dürfte ich kaum was posten. 
Aber "naturbedingt"? Wie meinst du das?

Ich bin schon lange genug im Forum um zu wissen, dass Rückmeldungen zu Programmen allgemein sehr spärlich sind 
Liegt natürlich auch sehr stark an der kleinen Community. Solange dich das nicht beunruhigt und du weiter postest, ist ja alles gut. Ich schaue mir die Pogramme jedenfalls immer wieder gerne an.
Ich wünschte, ich käme auch mal wieder zum Programmieren - im Moment komme ich, wenn ich sehr fleißig bin, auf 100 Zeilen im Monat ...
