ASPECT = _REAL (Read)
The aspect ratio
(x/y) of the picture to be created in modes other than Cursor, Array, and XY. The new
picture is the largest possible with the chosen aspect ratio that will fit within the
part of the reference picture defined by the fractional sizes (see Parameter FRACTION).
The justification comes from the value of MODE. Thus to obtain the largest picture, set
1.0. A null value (
!) does not apply an aspect-ratio constraint, and therefore
the new picture fills the part of the reference picture defined by the fractional
CURRENT = _LOGICAL (Read)
TRUE if the new picture is to lie within the
current picture, otherwise the new picture can lie anywhere within the BASE picture. In
other words, when it is
TRUE the current picture is the reference picture,
FALSE, the base is the reference picture.
DEVICE = DEVICE
The graphics device.
[Current graphics device
FILL = _REAL (Read)
The linear filling factor for the Array mode. In other words the fractional
size (applied to both co-ordinates) of the new picture within each of the XPIC
abutted sections of the picture being sub-divided. Each new picture is located
centrally within the section. A filling factor of 1.0 means that the pictures in the
array abut. Smaller factors permit a gap between the pictures. For example, FILL = 0.9
would give a gap between the created pictures of 10 per cent of the height and width of
each picture, with exterior borders of 5 per cent. FILL must lie between 0.1 and 1.0.
FRACTION( ) = _REAL (Read)
The fractional size of the new picture along each
axis, applicable for modes other than Array, Cursor, and XY. Thus FRACTION controls
the relative shape as well as the size of the new picture. If only a single
value is given then it is applied to both x and y axes, whereupon the new
picture has the shape of the reference picture. So a value of
0.5 would create a
picture 0.25 the area of the current or BASE picture. The default is
Parameter ASPECT is not null, when the default is
1.0. This parameter is not used
if the picture size is specified in centimetres using Parameter SIZE.
LABELNO = _INTEGER (Read)
The number used to form the label for the first
(bottom-left) picture in Array mode. It cannot be negative.
LBOUND( 2 ) =
Co-ordinates of the lower bound that defines the new picture.
The suggested default is the bottom-left of the current picture. (XY mode)
Method for selecting the new picture. The options are
"Cursor" for cursor mode (provided the graphics device has one),
"XY" to select
x-y limits, and
"Array" to create a grid of equal-sized FRAME pictures. The
remainder are locations specified by two characters, the first corresponding to
the vertical position and the second the horizontal. For the vertical, valid
C(entre); and for the horizontal the options are
OUTLINE = _LOGICAL (Read)
TRUE, a box that delimits the new picture is drawn.
PREFIX = LITERAL
The prefix to be given to the labels of picture created in Array mode.
It should contain no more than twelve characters. If the empty string
given, the pictures will have enumerated labels. Note that the database can
contain only one picture with a given label, and so merely numbering labels
increases the chance of losing existing labels. A
! response means no labelling
is required. The suggested default is the last-used prefix.
SIZE( 2 ) =
The size of the new picture along both axes, in centimetres,
applicable for modes other than Array, Cursor, and XY. If a single value is
given, it is used for both axes. If a null value (
!) is given, then the size of
the picture is determined by Parameter FRACTION.
UBOUND( 2 ) = _REAL
Co-ordinates of the upper bound that defines the new picture. The
suggested default is the top-right of the current picture. (XY mode)
The number of new pictures to be formed horizontally in the BASE
or current picture in Array mode. The total number of new pictures is XPIC
The value must lie in the range 1–20. The suggested default is
The number of new pictures to be formed vertically in the
BASE or current picture in Array mode. The value must lie in the range 1–20.
The suggested default is the value of Parameter XPIC.
