Summary
The Output Size dialog box is displayed when you choose Specify Output Size
from the Output Size list. From the dialog box, you set the output resolution
of the rendered image.
When you set a unique output size, it gets added to the Output Size list of the
Render Settings palette. Four unique output sizes can populate the output size
list, but they do not get saved with the current drawing and they are not
maintained from one drawing session to the next.
List of Options
The following options are displayed.
Width
Sets the width resolution of the output image, in pixels.
You can set the width anywhere from 8 to 4096.
Height
Sets the height resolution of the output image, in pixels.
You can set the height anywhere from 8 to 4096.
Image Aspect
Sets the aspect ratio, the ratio of width to height, of the rendered image.
Changing this value changes the Height value to maintain the correct
dimensions for the active resolution. The image aspect value is always expressed
as a multiplier value.
Lock/Unlock Image Aspect
Locks the aspect ratio when using a custom output resolution.
When it is locked, the Width and Height spinners are locked to each other;
adjusting one alters the other to maintain the aspect-ratio value. When
unlocked, changes to either Width or Height affects only the Image Aspect
setting.
NOTE In viewports, the camera's frustum changes to reflect the image aspect
ratio you set in the Output Resolution dialog box. This change takes place when
you exit the dialog box.
Preset Resolution Buttons
Sets one of four most commonly used output resolutions.
