Strange behaviour with gflBitmapHasIPTC and gflBitmapGetIPTC

[Ithier]

Hi,

I have written a function to retreive IPTC data. First I call the gflBitmapHasIPTC function and if it returns true, then I call gflBitmapGetIPTC.
Generally it works fine, but for some tiff images (not all) gflBitmapHasIPTC return true, but gflBitmapGetIPTC returns a NULL pointer !
This is obviously not a big problem, but is it normal ?

Yes, some pictures have a IPTC field, but without data
