    no bug .png Datei, IrfanView sagt: Falsche oder unbekannte PNG Datei.

    Ich habe hier ein .png, das IrfanView nicht öffnen kann. Das Fenster bleibt schwarz und es kommt der Fehler:
    "Dekodierungsfehler! Falsche oder unbekannte PNG Datei."

    Man könnte nun annehmen: Datei kaputt oder falsche Endung, doch:
    - Windows zeigt die Thumbnail-Vorschau korrekt an
    - Datei kann mit Paint problemlos geöffnet werden
    - Datei kann mit Office 2010 geöffnet werden
    - selbst wenn ich die Datei mit Paint editiere und wieder als .png speichere, kommt immer noch der Fehler
    - TrIDNet File Identifier erkennt die Datei als PNG

    Ich habe extra nochmal die neuste IrfanView Version und die neusten Plugins installiert (32Bit).
    Mit anderen PNGs habe ich keine Probleme.

    Die Datei habe ich angehängt.

    I can confirm that, same thing with 64-bit version, but I'm not able to find the reason, why this is rejected. Gimp 2.9, zoner 17, wildbit viewer and rawtherapee can all open the image without problems.

      I have sent the image to Irfan Skiljan.

      I can open it in FastStone Capture. If I save it from there, IrfanView can then open it.

        Irfanview does not show the picture, however you can open it in Iviews HEX-Viewer [F3]. The structur of this pictures differs from all other PNGs I have compared
        in the way, that there is some additional data stored in about line 3 to 23. Maybe that's the reason why Iview does not dhoe the picture.

          I received a reply from Irfan Skiljan.

          So, do as suggested. Open it in another program that is more tolerant of defective files, and save it.

            Ok, thank you, no problem, I could help myself. I just thought it might be a bug and I ought to reoprt it.

            Funny though that Paint conserves the error while processing it.

            Thanks to all who answered!
