[magick-users] Problems handling certain jpgs.

[Eddie Stuart]

Yup - the submitted photos are converted to PNG for processing as below.

Why would some PNGs have a zero-length profile after conversion?

Thanks,

Eddie

HoldFile = submitted file
WorkFile = converted PNG file
StopFile = final JPG file

    set img = Server.CreateObject("ImageMagickObject.MagickImage.1")
    result = img.Convert((MyPath & HoldFileName), WorkFile)
**  result = img.Convert("-resize", "150x150", WorkFile, WorkFile)
    result = img.Composite("-gravity", "NorthWest", NWcorner,
WorkFile, WorkFile)
    result = img.Composite("-gravity", "NorthEast", NEcorner,
WorkFile, WorkFile)
    result = img.Composite("-gravity", "SouthWest", SWcorner,
WorkFile, WorkFile)
    result = img.Composite("-gravity", "SouthEast", SEcorner,
WorkFile, StopFile)

** first image generates error on this line
