I'm puzzled: now I removed the vampyre lib from the ide, in a form I
need ImagingComponent and ImagingClassed.
I drop a TPicture with a png image and it is blank at runtime.
This time it is streamed as TPortableNetworkGraphic *but*
FindClassName cannot find it.
How is that possible?
AAAAAAAGH Because the Vampyre library explicitly deletes it
{$IFDEF COMPONENT_SET_LCL}
// Unregister Lazarus´ default PNG loader which crashes on some PNG
files
TPicture.UnregisterGraphicClass(TPortableNetworkGraphic);
{$ENDIF}
Two years later I forgot about this issue and I found it again with
lazarus 3.2 and a freshly downloade vampyre imaging library (which is
still at version 0.80 in the online package manager, though I see that
the line is still there in the github repository).
Probably my fault for not reporting the issue to Vampyre, I just hope
my memory serves me better next time.
