AFAIK:
TPicture.Width is the TGraphic container size.
TPicture.jpeg.Width is the width declared in the jpeg image.
TPicture.Bitmap.Width is the width of the bitmap in pixels.
Mostly the 3 will have the same value but extracted from different
sources.
If I start off using a bitmap, and all of a sudden start using jpeg,
will it automagically work or does one have to initiate the jpeg in some
way?
Example: you start off working with a classic BMP, but then 60 lines of
code later you want to work with it as a jpeg. Do you just magically
start working with a jpeg without any worry, or you have to take some
precautions?
Likely, this is explained in a article on the wiki somewhere, I don't
know :-)
