cartopol
Convert cartesian to polar coordinates
Description
Converts a cartesian-coordinate pair consisting of real and imaginary values into a polar-coordinate pair consisting of distance and angle values.
Arguments
None.
Attributes
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'
'18'
'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'
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
bang will output the most recently stored coordinate pair conversion.
int
Converted to float.
- coordinate
[int]
float
In left inlet: The x coordinate of a Cartesian pair to be converted into a polar coordinate pair consisting of distance and angle values. When used in an audio context, the value represents the real part of a frequency domain value to be converted into a polar coordinate pair consisting of amplitude and phase values.
In right inlet: The y coordinate of a Cartesian pair to be converted into a polar coordinate pair consisting of distance and angle values. When used in an audio context, the value represents the imaginary part of a frequency domain value to be converted into a polar coordinate pair consisting of amplitude and phase values.

[float]
Output
float
Out left outlet: The distance portion of the polar coordinate pair. When used in an audio context, the value represents the magnitude (amplitude) of the frequency represented by the currently input.
Out right outlet: The angle portion of the polar coordinate pair. When used in an audio context, the value represents the phase, expressed in radians, of the frequency represented by the current input. If only the left outlet is connected, the phase computation is not performed.
