Images created by DIALux are always in a ratio of 4:3. This is for the most presentation techniques a good value (TV, projector, monitor,…). Modern laptops or TVs have another ratio e.g. 16:9 and 16:10. After loading the POV file the user can search for the camera command in the text. The search command is one of the drop down menus at the top of the window. In the menu “search” you can select “find” and enter “camera”. Below “camera” there is a command for the “right vector” of the used camera. There is written: <1.3333,0,0>. 1.333 is the ratio 4:3. To achieve a ratio of 16:9 enter there <1.7777> or 16/9 (E.g. right <16/9,0,0>). It is important to define a correct picture size with the same ratio. The following pictures of the same scene are made in 4:3 and 16:9 ratio. The 4:3 picture has a resolution of 800 by 600 pixel. If you want to keep the height of 600 pixel, you have to multiply the width with the desired ratio. In our example 600 x 16/9 = 600 x 1,7777 = 1066.

You can manipulate the picture size by entering the desired size into the edit field with +w and +h directly followed by the numbers. w means width, h means height.
