DESCRIPTION

The image command allows the user to make color or grayscale images from a SAC 3-D data file such as those generated by the spectrogram, scallop, or bbfk commands. It can also be used to plot imported data provided they are in the SAC 3-D data format. Different sections of the image can be viewed using the xlim and ylim commands and amplitudes can be scaled using the usual unary operations provided in SAC.
