scaleKey is undoable, NOT queryable, and NOT editable.
This command operates on a keyset. A keyset is
defined as a group of keys within a specified time range on one or
more animation curves.
The animation curves comprising a keyset depend on the value
of the "-animation" flag:
-
keysOrObjects:
- Any active keys, when no target objects or -attribute
flags appear on the command line, or
- All animation curves connected to all keyframable
attributes of objects specified as the command line's
targetList, when there are no active keys.
-
keys:
Only act on active keys or tangents.
If there are no active keys or tangents, don't do anything.
-
objects:
Only act on specified objects. If there are no objects specified, don't
do anything.
Note that the "-animation" flag can be used to override
the curves uniquely identified by the multi-use
"-attribute" flag, which takes an argument of the form
attributeName, such as "translateX".
Keys on animation curves are identified by either
their time values or their indices. Times and indices can
be given individually or as part of a list or range (see Examples).
This command takes keyframes at (or within) the specified times (or time ranges)
and scales them. If no times are specified, the scale is applied to active keyframes
or (if no keys are active) all keys of active objects.

Argument types |
Properties |
|
animation(an)
|
string
|
|
|
Where this command should get the animation to act
on. Valid values are "objects," "keys," and
"keysOrObjects" Default: "keysOrObjects." (See
Description for details.)
|
|
attribute(at)
|
string
|
|
|
List of attributes to select
In query mode, this flag needs a value.
|
|
autoSnap(asp)
|
boolean
|
|
|
Auto snap scaled keys if True.
Default value depend on scaleKeyAutoSnap option
|
|
controlPoints(cp)
|
boolean
|
|
|
This flag explicitly specifies whether or not to include the
control points of a shape (see "-s" flag) in the list of attributes.
Default: false. (Not valid for "pasteKey" cmd.)
In query mode, this flag needs a value.
|
|
float(f)
|
floatrange
|
|
|
value uniquely representing a non-time-based
key (or key range) on a time-based animCurve. Valid
floatRange include single values (-f 10) or a
string with a lower and upper bound, separated by a
colon (-f "10:20")
In query mode, this flag needs a value.
|
|
floatPivot(fp)
|
float
|
|
|
Scale pivot along the x-axis for float-input animCurves
|
|
floatScale(fs)
|
float
|
|
|
Amount of scale along the x-axis for float-input
animCurves
|
|
hierarchy(hi)
|
string
|
|
|
Hierarchy expansion options. Valid values are "above,"
"below," "both," and "none." (Not valid for "pasteKey" cmd.)
In query mode, this flag needs a value.
|
|
includeUpperBound(iub)
|
boolean
|
|
|
When the -t/time or -f/float flags represent a range
of keys, this flag determines whether the keys at the
upper bound of the range are included in the keyset.
Default value: true. This flag is only valid when
the argument to the -t/time flag is a time range with
a lower and upper bound. (When used with the "pasteKey"
command, this flag refers only to the time range of the
target curve that is replaced, when using options such
as "replace," "fitReplace," or "scaleReplace." This
flag has no effect on the curve pasted from the clipboard.)
|
|
index(index)
|
uint
|
|
|
index of a key on an animCurve
In query mode, this flag needs a value.
|
|
newEndFloat(nef)
|
float
|
|
|
The end of the float range to which the float-input targets
should be scaled.
|
|
newEndTime(net)
|
time
|
|
|
The end of the time range to which the targets
should be scaled.
|
|
newStartFloat(nsf)
|
float
|
|
|
The start of the float range to which the float-input targets
should be scaled.
|
|
newStartTime(nst)
|
time
|
|
|
The start of the time range to which the time-input targets
should be scaled.
|
|
scaleSpecifiedKeys(ssk)
|
boolean
|
|
|
Determines if only the specified keys are affected by the scale.
If false, other keys may be adjusted with the scale. The
default is true.
|
|
shape(s)
|
boolean
|
|
|
Consider attributes of shapes below transforms as well,
except "controlPoints". Default: true. (Not valid for "pasteKey" cmd.)
In query mode, this flag needs a value.
|
|
time(t)
|
timerange
|
|
|
time uniquely representing a key (or key
range) on a time-based animCurve. See the code
examples below on how to format for a single
frame or frame ranges.
In query mode, this flag needs a value.
|
|
timePivot(tp)
|
time
|
|
|
Scale pivot along the time-axis for time-input animCurves
|
|
timeScale(ts)
|
float
|
|
|
Amount of scale along the time-axis for
time-input animCurves

# time=(10,) means the same as (10,10)
# time=(0,10) means all keys up to (and including) time 10 (in the current time unit).
