In regards to logging, yes I have been using a combination of
REALbasic System.DebugLog and DebugStr. In REALbasic a
System.DebugLog msg is right before the call to the method and it

DebugStr call which is never printed,
At the very start of the function?
Yes. The app crashes before the DebugStr from the C plugin. It
crashes here:
If (ImageFX Is Nil) Then ImageFX = New PictureFX(Image)
System.DebugLog "PictureFX object created."
If (ImageFX Is Nil) Then System.DebugLog "ImageFX is Nil"
System.DebugLog "Picture Width is " + Str(ImageFX.Width)
System.DebugLog "Picture Height is " + Str(ImageFX.Height)
System.DebugLog "Picture Depth is " + Str(ImageFX.Depth)
ImageFX.InvertRGB <<<<<<<<<<<<<<<<<<< CRASH ON CALL
System.DebugLog "InvertRGB completed."
Image = ImageFX.ToPicture
System.DebugLog "PictureFX to Picture conversion completed."
--------------------
CONSOLE OUTPUT:
--------------------
PictureFX object created.
Picture Width is 512
Picture Height is 512
Picture Depth is 32

so the crash seems to be occurring somewhere in the framework even
before my plugin method is getting called. There doesn't seem to
be anything else that I can do to isolate this.
Then perhaps the function is declared wrong.
I hope so, but I cannot figure out how.
The fact that you are define the the REALClassDefinitions and all
theo other data in .h files can't help. You should define them in
a .cpp file. This way data doesn't get duplicated across multiple
files that include the .h file.
#include is nothing more than a dumb preprocessor you see. So
anything in a .h file gets put into all the .cpp files that include
it. So you've got the same data defined multiple times now if you
have multiple .cpp files that include that .h of yours. If it's
only 1 .cpp it might not be a problem, but I'd really avoid it if I
were you just on good coding practice grounds.
That is a good idea... I have an #ifndef condition in that .h file,
but I had the #endif only protecting calls into other header files.
I moved the #endif to the last line in the .h file and ran the plugin
again with the same result.
