View class resource descriptions
-
vpXF
-
vpXF specifies the location of left edge of the
View object's bounding box in NDC space.
Default: 0.2
-
vpYF
-
vpYF specifies the location of top edge of the
View object's bounding box in NDC space.
Default: 0.8
-
vpWidthF
-
vpWidthF specifies the width of View
object's bounding box in NDC units.
Default: 0.6
-
vpHeightF
-
vpHeightF specifies the height of View
object's bounding box in NDC units.
Default: 0.6
-
vpOn
-
Set vpOn False to disable the Draw method
of a View object. When its Draw
method is disabled, the view, its
View class children, its overlays, and its added
annotations do not appear on the workstation when a
Draw is executed.
Default: True
-
vpKeepAspect
-
While the boolean resource vpKeepAspect is True, the
View object keeps its initial shape (aspect ratio);
however you may modify its size resources. If you modify either or
both the size resources, vpWidthF and vpHeightF,
View will constrain its new bounding box to the
largest box with an aspect ratio matching the original shape that can be
inscribed within a box of the specified size. When
vpKeepAspect is False, View places no
constraints on the shape of its bounding box when you modify the size
resources.
Default: False
-
vpUseSegments
-
When the boolean resource vpUseSegments is set True for a
View class object, the object will, if it is
able, create a segment and draw into it while it draws to the
designated Workstation object. The segment is stored
as a file, and contains the low-level commands required to re-create
the object, possibly with transformations to the position, size, or
shape applied. When you next draw the object, assuming none of the
object's resources other than vpXF, vpYF,
vpWidthF, or vpHeightF have been modified, it will
recreate its image based on information stored in the segment. Using
segments can substantially shorten the time required to perform a draw
when the plot contains elements, such as filled maps, that require
considerable computation to generate initially. Note that because the
transformations differ slightly, a segment drawn at a different size
from the size at which it was created may not match in every detail
the plot resulting from a new draw of the object at that size.
Default: False
-
vpAnnoManagerId
-
If the View object is currently functioning as an
external annotation of a Plot Object, this read-only resource contains
the id of the AnnoManager object used to manage the
View object's location and size. If the
View object is not currently an annotation, the value
of the resource is set to
NullObjId
(0).
Default: False
