Dear developers,
I am trying to make a GIMP plugin that can open a new drawable on the
screen. Just like when you make one from File->New.
Hi!
You can't show a drawable by itself, it needs to be in an image. Also,
an image can't show itself, you must create a display for that. You are
also using the API in weird ways, for example, objects such as layers
and images are represented by integers in the plug-in context.
You are also saying that the plug-in takes the active image and drawable
as parameter, but since you are creating a new image, you are not
interested in those values (I assume) so there is no point in specifying
these as arguments to the hello-world procedure.
I have attached a rewritten version of main.c (called hello-world.c
since that is a name that doesn't conflict as much) that should do what
you want. You might also want to consider using a scripting language
like Scheme or Python for this.
