Dialog Box - called from: File menu
------ Macintosh Only ----------
Note that this type of output may be referred to elsewhere as Metafile output. This option can write images either to the Clipboard or to PICT files, in either of two formats: (a) a rescalable 2-dimensional Picture or metafile, or (b) a raster image or bitmap. For 3D Drawing modes, this option writes a two-dimensional image and only bitmaps are available, but see the VRML Files and POV-Ray options for files which actually contain three-dimensional data
Macintosh Pictures, as used here, are images containing lines or vectors and fills of regions defined by lines, that can be rescaled without necessarily losing resolution. They record the drawing commands that are used for the screen or standard printer output, but the result may depend on the software or device in which they are used.
Bitmaps or raster images record every pixel, so they are not susceptible to undesirable modification by other software. Although most "painting" software can resize bitmaps, this usually causes a loss of quality, so it is best to save a bitmap in exactly the desired size. Note that you can also save bitmaps in the PNG file format (File menu), which is superior is some respects to PICT files.
If color output is selected, you can choose either 16- or 32-bit color depth - 8-bit (256-color) files cannot be written.
You can select the nominal dots per inch/centimeter, but note that programs which read the file may ignore this and show the image at 72 dots per inch.
Background color. If this option, which applies only to PICT output, is on, the color selected in the Background Color dialog of the Input2 menu will be applied in color output only. Background in b/w output is always white.
In 3D drawing modes PICT (bitmap) output always has 32-bit pixel depth.
