Hi Greg,
The WinForms PictureBox control is pretty basic, it's mostly designed
for displaying images, not really for drawing.
In the distant past I've used Leadtools Imaging Pro for a WinForms
document management project that required annotation, but that can get
expensive if your needs are basic and looking towards the future I can't
quite tell what their .NET 7+ story is anymore.
These days it might be worth looking into SkiaSharp canvas drawing, and
there are also some PDF export samples in the github repository.
cheers,
Tony

Hi Everyone,
I’m migrating an old VB6 app to .NET. It used a PictureBox control and
of course that had all sorts of options for drawing all over it.
In the end, it was used to generate JPG images that were printed.
I’d really prefer to use PDF as output anyway.
Does anyone have a favourite control that presents a drawable surface
that you can output as a PDF? (Or ideally as a JPG as well?)
I get the impression that the .NET version of the PictureBox is way
different, although it does seem to expose a Graphics object that you
can then draw on. Is it better to stick with the standard .NET control
and work out how to migrate the code?
Regards,
Greg
