CREATE creates a new blank image, giving all the pixels in that image some constant value (the default is 0.0). Any image that is in the buffer will be destroyed. Use CONST=c to set the initial values of all of the pixels to 'c'.
The BOX=b keyword is used to define the image size and location. This makes the new image have the size and location of bux 'b'. See BOX for instructions for defining boxes. You may also give the size and location of the new image with the keywords SR, SC, NR, NC, or N. NR and NC, or N, are required. If SR, SC , CR, and CC are not given, the default origin is (0,0).
If you wish to have the header cards in the new buffer populated with cards from an existing buffer (except for cards having to do with image size, origin, etc.), use the HEADBUF=oldbuf keyword to copy cards from buffer oldbuf.
