Saving Images.

Easy as 1-2-3:

1. Get the picture you want on the screen. Use the options of the Image Panel to enhance.
   
2. Use ``Save Image'' (Alt-i) in Menubar File or the same command from the Image Panel to set the filename to be saved. The program will go into single buffer mode (for highest quality images on low-end machines), remove the menubar and give you a message as your window title.
   
3. Hit the ``PrintScreen'' key to actually save the image to disk, or the ``Pause'' key to cancel the save. If PrintScreen is hit, rendering begins. On completion, the graphics state and menubar will be restored, along with a pop-up message that your file has been saved.

Hints:

Example Images shows images of representative drawing types and how to make the data.

For the highest possible resolution, maximize the window before you begin (however, if you have text, you have to consider the effect of size reduction if for prints).

For even higher than full-screen resolution, try the SuperSampling options of the ImagePanel on an SGI machine, or use a supported raytracing package.

For the highest possible quality, adjust all appropriate graphics widgets to high values, and set the full-screen antialiasing level to the limit. (note: you may want to go into FastDraw mode (toggle with Alt-f) to make all the adjustments)

For identically sized images, invoke ribbons with the -w option.

For slides, use a black background and vivid colors.

For printing, use a white background, fewer and more pastel colors, and turn on outlining in the View menu for a nice line-drawing effect.

For black and white images, check out the options of the Image Panel.

For stereo slides, save the first (left) image, hit (Alt-y) for the stereo rotation, then save the right image (you can undo the rotation with Alt-u)

For stereo prints, can do as above and then composite the images with standard tools, or display as side-by-side stereo (Alt-2) and save the left/right pair as one image.

To scale, crop, enhance (I personally like to sharpen about 10%) on an SGI machine use the command: imgworks file.rgb

To convert between graphics formats, use imgworks on the SGI, or the free imconv package from the San Diego Supercomputer Center.

For DEC machines, /freeware/bin/ImageMagick/import has been recommended.
