Subject: Re: Saving the image in a canvas

I am using 2D Draw from someone on this list
well I think when the picture is drawn in the paint part of the
program it's Canvas.Paint
but when you import a picture to the paint field it's canvas.backdrop
False, sorry! You are able to do what you want.
But, everything you draw "in the Paint Event" is there until the next refresh...
and lost after that if the code is not called _by_ the Paint event.
What people says here (in the Getting Started list / in the NUG List) since the
last seven years is to use an Offscreen Picture and assign it to the Canvas (or
Window) Backdrop:
Canvas1.Backdrop = OffscreenPict
other adventage is that once you draw everything in the OffscreenPict, you can
save the Canvas contents using:
f.SaveAsPicture OffscreenPict
isn't life sunny sometimes ?
BTW: you create the OffscreenPict, draw to it
(OffscreenPict.Graphics.<draw-what-you-want>) and assign it (see above) to the
Canvas or Window Backdrop.
At last, if you want to implement drag and drop on your canvas/window, use the
Backdrop property...
Now, if your questions in reality are: why do I not found these ansers in the
documentation... Express yourself according your thinking.
REALbasic documentation is better than Apple Mac OS X 10.4, but by a hair width,
not more :(
[yes, this is to say both are bad; but things can go worst :( OR BETTER :)]

PS: some Language Reference quotes:
Window.Backdrop Property
Syntax
Backdrop as Picture
A picture object that will be drawn in the window when the window opens.
Canvas.Backdrop Property
Syntax
Backdrop as Picture
The Picture that will automatically be drawn into the area. Must be a PICT on
Macintosh or BMP or PNG on Windows and Linux unless the user has QuickTime
installed (Windows and Macintosh only).
