Changing resolution...


Hello !

I'm using PoV-Ray for Windows 9x. You could set the resolution of the
rendered image in the ListBox (like "320x200 NoAA"). But there are only
some possebilitys, and I need a picture, which width is small, but which
is very high (like "100x400" or so...).

My questions:

1.) How can I choose another resolution then given in this list-box ?

2.) Is it possible to "save" the resolution in the PoV-Code ?

Regards

Martin

P.S.: Please mail your ideas, too. Thanks !

  You can of course look up the proper command line switches in the docs
or for custom sizes like that you can add them to your quickres.ini file.
The format for adding custom sizes to the image size selection window is
pretty straight forward and you should have no problem understanding how
to modify it by looking at it's current contents. You will need to restart
the program for the contents of the window to change.

  No it is not possible unless you have a seperate .ini file for your
scene file. Look in the docs for instruction on setting up a custom
.ini file and how to use them.

  You can either specify the resolution in the command line field in the
rendering settings menu this way:

-w400 -h200

or you can do it the hard way, by editing either the povray.ini-file or
the specific .ini-file for the current scene. If I remember correctly, the
lines were:

Width=400
Height=200

  (You can also type the short version in the .ini-file, though)

):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/

    You can save the .ini file then click on the "INI" button and choose
"set but don't render" and that refreshes the list box.

Go to the Tools menu and select "Edit secondary INI file". There
you'll see the different preset resolutions in the order they appear
in the drop-down resolution menu. The format is:

[Name]
Width=100
Height=400
Antialias=on/off (choose which one)

For more INI settings read the docs, but this should give you a good
start. The other replies mentioned the quick solutions, but this has
the advantage that you save this resolution as a preset you can
quickly select later.

Have fun POVing!

To match the Ini with the 'camera' don't forget to use 'up y*4' 'right x*1'
(less the quotes) or any other ratio to go with the changed output
resolution.

I like the distortion I get sometimes when I specify non standard image sizes.

Here's a little bit about aspect ratio:

The "secondary ini file" that Peter mentioned is set up for a 1.33:1
Academy ratio
which means if you have a frame that is 1 cm tall the width is 1.33cm .
In the case of Peter's example above you'll need to determine the
correct aspect ratio
Or you'll get a very squished looking image. So to figure it out just
divide
100/400 = 0.25:1 aspect ratio and then enter it in your right vector
like so:

camera {
  location <blah,blah,blah>
  up    <0,1,0>
  right  <0.25,0,0>
  look_at <blah,blah,blah>
}

I personally like 2.2:1 (70mm flat) and have several resolution sizes in
my Quickres.ini .
