jit.line
Generate timed ramp synched with render context
Description
Generate ramps and line segements from one value to another within a specified amount of time, and output in synch with and timed by an external render context. jit.line functions as a drop in replacement for standard Max line object, but removes stuttering associated with unsynched output between the line timer and context frames.
Arguments
None.
Attributes
automatic[int]
Enables automatic update and output (default = 1). Requires a valid drawto context for synching with. When disabled updates and output require a bang message.
drawto[symbol]
Bind to the named drawing context, allowing for updates to be received automatically when automatic is enabled.
enable[int]
Enables animation and output of interpolated value (default = 1).
fixed_delta[float64]
Fixed frame delta time for calculating time output (default = 0.0). When non-zero, time functions will use this value to calculate output, rather than the delta time since last update.This can be useful when animating at a fixed rate regardless of the actual update rate.
name[symbol]
Specifies the name of the instance (default = UID).
targetname[symbol]
Target Name (unused)
timevalue[float]
read-only
Current interpolated value
ui_priority[int]
UI Priority (unused)
Common Box Attributes
annotation[symbol]
Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.
background[int]: 0
Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.
color[4 floats]
Sets the color for the object box outline.
fontface[int]
Sets the type style used by the object. The options are:
plain
bold
italic
bold italic
Possible values:
0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'
fontname[symbol]
Sets the object's font.
fontsize[float]
Sets the object's font size (in points).
Possible values:
'8'
'9'
'10'
'11'
'12'
'13'
'14'
'16'

'20'
'24'
'30'
'36'
'48'
'64'
'72'
hint[symbol]
Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.
ignoreclick[int]: 0
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile[symbol]
You can override the default appearance of a user interface object by assigning a JavaScript file with code for painting the object. The file must be in the search path.
patching_rect[4 floats]: 0. 0. 100. 0.
Sets the position and size of the object in the patcher window.
position[2 floats]
write-only
Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.
presentation[int]: 0
Sets whether an object belongs to the patcher's presentation.
presentation_rect[4 floats]: 0. 0. 0. 0.
Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.
rect[4 floats]
write-only
Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).
size[2 floats]
write-only
Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.
textcolor[4 floats]
Sets the color for the object's text in RGBA format.
textjustification[int]
Sets the justification for the object's text.
Possible values:
0 = 'left'
1 = 'center'
2 = 'right'
valuepopup[int]: 0
For objects with single values, enabling valuepopup will display the object's current value in a popup caption when the mouse is over the object or it is being changed with the mouse.
valuepopuplabel[int]: 0
Sets the source of a text label shown in a value popup caption.
Possible values:
0 = 'None'
1 = 'Hint'
2 = 'Scripting Name'
3 = 'Parameter Long Name'
4 = 'Parameter Short Name'
varname[symbol]
Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.
Messages
bang
Output interpolated value when automatic disabled
int
Set current value and output immediately
float
Set current value and output immediately
list
Use various list combinations to reach a target value.
In one list combination, the first number specifies a starting value, followed by a comma and a number pair. The first number in the pair specifies the target value. The second number of the pair specifies the total amount of time (in milliseconds) in which jit.line should reach the target value. In that amount of time, numbers are output regularly in a line from the currently stored value to the target value.
An example of this type of list is 0, 1 1000 0 1000 . In this example, output would go from the starting value of 0 to 1 in one second, then back down to 0 in one second. Once the first ramp has reached its target value, the next one starts. A subsequent list , float , or int in the left inlet clears all ramps yet to be generated.
If the list has an even number of elements greater than three, each pair of elements is considered a destination-ramptime pair in a breakpoint function. If the list has an odd number of elements greater than three, the last element will be ignored.

update
Same functionality as bang message
