Rearrange Bits

This option provides a flexible method for rearraging the order of the bit planes within an image. In addition, individual bit planes may be set or cleared.

Rearrange bits on which buffer ?

This entry specifies the buffer containing the image which is to be rearranged. Any valid DigImage buffer may be used. The selected buffer is made the current output buffer. Extended memory buffers are vectored through buffer 0.

Rearrange bits in Window or whole Screen ?

The rearrangement of bit panes may be performed on the image in the entire screen (<S>), or confined to a window (<W>) within the buffer.

Window Selection: Region to be operated on.

If the bit pane rearrangement to be confined to a window, the standard DigImage window selection submenu is produced to aid the window specification. For more details on the specification process, consult the [H Help] option within the window selection submenu.

Bit #: Use what bit of source image (-1 => set, -2 => clear) ?

For each of the eight bit planes in the resulting image, starting with the least significant bit (bit 0), the bit plane to be used from the source image should be specified. Note that each bit plane in the source image may be duplicated into any number of bit planes in the resultant image. As an alternative to specifying a source image bit plane, a given bit plane may be set (-1) or cleared (-2) in the resultant image.
