Saves an image from the display window. Images are saved in TIFF, TARGA, JPEG, and PNG format depending on the extension within the filename parameter. For example, image.tif will have a TIFF image and image.png will save a PNG image. If no extension is included in the filename, the image will save in TIFF format and .tif will be added to the name. All images saved from the main drawing window will be opaque. To save images without a background, use create-graphics.
Saves an image identical to the current display window as a file. May be called multple times - each file saved will have a unique name. Name and image formate may be modified by passing a string parameter of the form "foo-####.ext" where foo- can be any arbitrary string, #### will be replaced with the current frame id and .ext is one of .tiff, .targa, .png, .jpeg or .jpg Examples: (save-frame) (save-frame "pretty-pic-####.jpg")
