In POV, there are two values that need to agree -- the up/right camera
ratio, and the render height and width.  If I design a scene to be, for
example, greeting card aspect (8:5) or square (1:1) or golden (1:phi), I set
the camera to suit.  Fine.

But using the GUI in POV-Windows, I have to choose a different INI file to
give appropreate resolution choices in the drop down box.  This would not be
an issue if I only needed to do it once, but this choice "sticks" and stays
that way no matter which image file I have loaded and "on top".

Is there a way to associate INI settings on a per-POV file basis, and tell
the GUI to read =that=, and still let me interactivly choose my mode (large,
small, low-Q, etc.) from my list of very common settings for that particular
image?

Edit the quickres.ini to something like this :

[200x200 LQ]
width =
height = 
.

Sounds like something for #write and #read. I've not touched anything
like this yet, but of course if you could output those parameters to a
single particular re-written file each time it's invoked, ie.
Aspect.ini, then all you'd need do is select that ini once and leave it.

#fopen ASPECT "Aspect.ini" write

#write (ASPECT,"\"WIDTH=\",", RIGHT,","/n","\"HEIGHT=\", UP,"\n")

This is only a guess as to how this syntax works. Like I say, don't know
how to use it yet.
But never mind anyhow, because as far as I know you cannot affect the
image size settings *after* parsing begins unless the information is
already in the INI, not from within a scene which has begun. These are
the first things setup along with file type and all. Although I may be
wrong and the image size could be before the image creation and after
the scene parsing. I'm still a bit lost in the newer DOC.
This would mean a first render to set things up if it didn't work out as
planned, then a second render of the same thing to get the right INI
settings. Back to square one. Sorry to get your hopes up, no help.
Boy, do I ever need to get at some of this new (though older and older)
stuff.

You missed the point of the question.  I have multiple INI files to suit,
but want to automatically switch between them.  Or are you suggesting
putting =all= the different values I need in one INI file?  Again, not what
I'm looking for.

Then I missed your point, and therefore can't help you very much
I have a solution of using several Qickres.
one with 1:1 scales, one with 1:3/4 and so on.

Well, Moray does what you want, you choose the camera etc and basically
it creates the ini file to use for the render...you could write a short
program to do the same in most languages, but I don't believe POVRay has
the ability to do exactly what you want...

That's what I'm doing now, too.
I was wondering if there was a way to automatically choose the right
quickres file to go with the image. especially useful if several image files
are open in the IDE at the same time.

Well, #read and #write should bee your best bet...

[Seems like my last message did not pass, re-posting the meaningful part]

1. I agree, #write could do the trick;
2. Point is: #write is executed only at parse time, but you need to
write the aspect.ini file before;
3. Trick is: add a "Refresh" to your aspect.ini file with a 1x1
resolution, no display, no pause at end, no file output, nothing.
Just parse and trace one ray.  This parsing re-writes the aspect.ini
file according to the aspect ratio you need for the scene.
4. Not-sure-it-works part is: I don't know when POV-Ray re-loads the
aspect.ini file, or if it does.

Roland.

I like that!  Nice idea!

The parade could be something like a nem item, entitled "refresh",
which would parse the file and render a 0x0 or 1x1 image (short
calculation time) and still parse the file, so that the thing.ini file
would be rewritten.  Change scene, then select "refresh", render, then
select the correct aspect ratio from the menu...

I won't be able to try that since I'm not using Windows (which I don't
complain about), and anyway I don't really care, but I'd like to be
kept informed on how it goes.

Roland.
