@next Usage
|
|
|
|
IntuiViewer is a program written in AMOS (and a bit of assembler) that
|
|
displays pictures. Now, this kind of program would not be hard to write in
|
|
AMOS - except that IntuiViewer, as its name implies, displays the pictures on
|
|
Intuition screens. And to do that, it uses the Intuition Extension.
|
|
|
|
Naturally, since I'm the author of the extension as well, this program shows
|
|
off some of the capabilities of the extension. :-) Although the program is
|
|
not yet very complex, due to both my lack of much knowledge of graphics file
|
|
formats and the current state of the Intuition Extension. (I could have
|
|
waited to add more features before releasing the extension, but then I'd never
|
|
release it. :-) ) As I add more functionality to the extension, this program
|
|
will improve as well.

@node Usage
|
|
@prev Description
|
|
|
|
To run IntuiViewer, either double-click on its icon from the Workbench, type
|
|
"IntuiViewer" from the Shell, or load it into AMOS and run it.
|
|
|
|
When the program starts, it immediately brings the Workbench display to the
|
|
front if necessary. Then it opens a window and prints a welcome message, and
|
|
puts up a file requester. Here, you can choose any IFF ILBM picture you
|
|
want. If the file is not a valid IFF ILBM file, or if it cannot be displayed
|
|
for whatever reason (too many colours, out of memory, etc.), a requester will
|
|
pop up telling you what went wrong. Otherwise, a new screen will open up and
|
|
the picture will be displayed. The screen is a standard Intuition screen;
|
|
you can send it behind the Workbench screen with RightAmiga-M, or bring the
|
|
Workbench screen to the front with RAmiga-N. If you do this, you'll notice
|
|
that the IntuiViewer window contains information about the file. When you're
|
|
done looking at the picture, press Escape (either the IntuiViewer window or
|
|
the picture must be the active window - click on one, if necessary) to kill
|
|
it. At this point, the file requester will reappear. You can select a new
|
|
file if you want, or click on Cancel (or press RAmiga-C) to quit IntuiViewer.
|
|
Clicking on the close gadget of the IntuiViewer window will also quit the
|
|
program.
