zmap
Maps input range of values to output range
Description
Maps an input range of values and to an output range of values. Similar to scale, but clips values to the ranges, and does not allow inverted scaling.
Arguments
minimum-input[number]
optional
The minimum input value. If the low values is higher than the corresponding high value, the two values are reversed to preserve the high-low relationship.
maximum-input[number]
optional
The maximum input value. If the low values is higher than the corresponding high value, the two values are reversed to preserve the high-low relationship.
minimum-output[number]
optional
The minimum output value. If the low values is higher than the corresponding high value, the two values are reversed to preserve the high-low relationship. The zmap object will clip to the boundaries of the output range.
maximum-output[number]
optional
The maximum output value. If the low values is higher than the corresponding high value, the two values are reversed to preserve the high-low relationship. The zmap object will clip to the boundaries of the output range.

ignoreclick[int]: 0
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile[symbol]
JS Painter File
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'
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
Perform the scaling operation on the most recently received input value. If the range values have been changed, the scaling will be based on the new range.
int

.- input
[int]
float
In left inlet: The incoming value is scaled according to the mapping provided by the arguments, or values received in the other inlets.
Note: The preservation of the high-low relationship is different from the behavior of the scale object, which lets you do reverse scaling. Also, note that the zmap object will clip to the boundaries of the output range.
- input
[float]
(inlet1)
In second inlet: Sets the low input value. If the value is higher than the high input value, the two values are reversed to preserve the high-low relationship.
- minimum-input
[float]
(inlet2)
In third inlet: Sets the high input value. If the value is lower than the low input value, the two values are reversed to preserve the high-low relationship.
- maximum-input
[float]
(inlet3)
In fourth inlet: Sets the low output value. If the value is higher than the high output value, the two values are reversed to preserve the high-low relationship.
- minimum-output
[float]
(inlet4)
In right inlet: Sets the high output value. If the value is higher than the high output value, the two values are reversed to preserve the high-low relationship.
- maximum-output
[float]
list
In left inlet: A list of numbers sent to the left inlet will trigger the output of a list consisting of the results of performing the specified scaling operation on each item in the input list.
- input
[list]
Output
float
When zmap receives a value in its leftmost inlet, that value is scaled to the indicated output range of values.
