Dialog Box: PICT Files [Macintosh only] [File Menu]
This dialog can be called from the File menu when either the Spectra window or the Atoms window is active, and the image which goes into the PICT file can thus be either the spectra or the atoms plot.
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 (b) a raster image or bitmap.
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, the pixel depth of bitmaps will be the same as the current screen.
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 is on, the color selected in the Atoms Plot Parameters dialog (Settings menu) will be applied in color output only. Background in b/w output is always white.
See Frames for details of the frame and frame units.
