Hallo,
wahrscheinlich bin ich einfach zu dähmlich, habe eine SBF Datei, in der zwei Bilder (JPG) integriert sind, das erste Bild ( 8bit) kann ich ohne weiteres einlesen und darstellen, das zweite Bild bekomme ich aber nicht geregelt.
Hier die
Unit LibGfl von XNView, kann mir jemand helfen?
Ich lege einmal eine solche SBF Datei bei.
Vielen lieben Dank
