The Image Panel

The Image Panel (opened using File... Save Image...) allows the contents of the graphics window to be saved as a TIFF file.

• The Image Size section includes
  • Units (centimeters/inches/millimeters/pixels/points) - the units used for describing the options below
  • Image width - width in units of image
  • Image height - height in units of image
  • Get Pixels, a button that sets units to pixels and shows the actual pixel dimensions of the display in the width and height fields
  • Page Setup, a button that opens the Page Setup preferences

  When Maintain current aspect ratio is on, the image width/height ratio is constrained to match the width/height ratio of the graphics window (not including borders). Entering the width automatically adjusts the height and vice versa.

  When Maintain current aspect ratio is off, width and height can both be set as desired. Grow to Fit resizes the graphics window to match the image aspect ratio by increasing one window dimension (i.e., width or height), while Shrink to Fit resizes the graphics window to match the image aspect ratio by decreasing one window dimension. If the window has not been resized to match the image aspect ratio (as specified by the values entered for width and height), a saved image will include more than what is visible in the display.

• The Image Information section includes
  • Description: further explanatory text (to be entered) which will be placed in a saved image file without affecting the image
  • An Image Credits button that opens the Image Credits preferences (text that will appear in a saved image file without affecting the image)
  • A Citing Chimera button that brings up information on citing Chimera in a browser window.

Save As opens a dialog for saving the image as a TIFF file. Cancel dismisses the Image Panel, and Help opens this manual page in a browser window.

Note that the command copy is another route to saving and printing images, but cannot yield resolutions higher than that of the screen.
