TITLE:: FluidPlotter
|

|
||||
|
||||
DESCRIPTION::
|
||||
FluidPlotter is a viewer for plotting data.
|
||||
|
||||
|
||||
CLASSMETHODS::
|
||||
|
||||
METHOD:: new
|
||||
Creates a new instance of FluidPlotter
|
||||
|
||||
ARGUMENT:: parent
|
||||
A parent view to embed the FluidPlotter in. If no parent is passed, FluidPlotter will create a window for itself at the given bounds.
|
||||
|
||||
ARGUMENT:: bounds
|
||||
Where to show the FluidPlotter, either within the parent or on the screen (if no parent is passed).
|
||||
|
||||
ARGUMENT:: dict
|
||||
A link::Classes/Dictionary:: from a FluidDataSet dump method (or a similarly formatted Dictionary) that contains the data to be plotted.
|
||||
|
||||
ARGUMENT:: mouseMoveAction
|
||||
A function to execute on mouse down or mouse drag. This funtion is passed the strong::view:: (itself), strong::x position:: (scaled according to the xmin and xmax arguments of FluidPlotter), strong::y position:: (scaled according to the ymin and ymax arguments of FluidPlotter), strong::modifiers::, strong::button number::, and strong::click count::. The last two arguments are only useful on mouse down, not on mouse drag.
|
||||
|
||||
ARGUMENT:: xmin
|
||||
Minimum of the X range to display. Default is 0.
|
||||
|
||||
ARGUMENT:: xmax
|
||||
Maximum of the X range to display. Default is 1.
|
||||
|
||||
ARGUMENT:: ymin
|
||||
Minimum of the Y range to display. Default is 0.
|
||||
|
||||
ARGUMENT:: ymax
|
||||
Maximum of the Y range to display. Default is 1.
|
||||
|
||||
returns::
|
||||
An instance of FluidPlotter
|
||||
|
||||
INSTANCEMETHODS::
|
||||
|
||||
METHOD:: background
|
||||
Set the background link::Classes/Color::.
|
||||
|
||||
METHOD:: pointSize
|
||||
Set the size of a specific point.
|
||||
|
||||
ARGUMENT:: identifier
|
||||
Which point to set the size of.
|
||||
|
||||
ARGUMENT:: size
|
||||
What size the point should be. This is a multiplier applied to the default point size which is 6 pixels. A point size of "2" will render a point with a diameter of 12 pixels. A point size of "0.5" will render a point with a diameter of 3 pixels.
|
||||
|
||||
METHOD:: refresh
|
||||
Refresh the link::Classes/UserView:: inside the FluidPlotter.
|
||||
|
||||
METHOD:: xmin
|
||||
Set xmin property and refresh the plotter.
|
||||
|
||||
returns::
|
||||
xmin property.
|
||||
|
||||
METHOD:: xmax
|
||||
Set xmax property and refresh the plotter.
|
||||
|
||||
METHOD:: ymin
|
||||
Set ymin property and refresh the plotter.
|
||||
|
||||
METHOD:: ymax
|
||||
Set ymax property and refresh the plotter.
|
||||
|
||||
METHOD:: addPoint
|
||||
Manually add a single point to the FluidPlotter. Similar to the strong::addPoint:: method of link::Classes/FluidDataSet::, addPoint_ will not overwrite a point that already exists at the given identifier. Instead, a warning will be thrown.
|
||||
|
||||
ARGUMENT:: identifier
|
||||
The identifier associated with this point.
|
||||
|
||||
ARGUMENT:: x
|
||||
X position of the point.
|
||||
|
||||
ARGUMENT:: y
|
||||
Y position of the point.
|
||||
|
||||
ARGUMENT:: color
|
||||
What link::Classes/Color:: to make the point. If nothing is provided the point will default to link::Classes/Color::.black.
|
||||
|
||||
ARGUMENT:: size
|
||||
What size to make the point. This is a multiplier that modifies the default point size of 6 pixels. The default is 1. See strong::pointSize:: method above.
|
||||
|
||||
METHOD:: setPoint
|
||||
Similar to the strong::setPoint:: method of link::Classes/FluidDataSet::, setPoint_ will add a new point to the FluidPlotter. If a point already exists at the given identifier, it will be overwritten.
|
||||
|
||||
ARGUMENT:: identifier
|
||||
The identifier associated with this point.
|
||||
|
||||
ARGUMENT:: x
|
||||
X position of the point.
|
||||
|
||||
ARGUMENT:: y
|
||||
Y position of the point.
|
||||
|
||||
ARGUMENT:: color
|
||||
What link::Classes/Color:: to make the point. If nothing is provided the point will default to link::Classes/Color::.black.
|
||||
|
||||
ARGUMENT:: size
|
||||
What size to make the point. This is a multiplier that modifies the default point size of 6 pixels. The default is 1. See strong::pointSize:: method above.
|
||||
|
||||
METHOD:: highlight
|
||||
Increase the size of a point to make it more salient. Only one point can be "highlighted" at a time. To increase the size of multiple points, use method strong::pointSize::.
|
||||
|
||||
ARGUMENT:: identifier
|
||||
The identifier of the point to make salient. If nil is passes, not points' sizes will be changed.
|
||||
|
||||
METHOD:: dict
|
||||
Set a new link::Classes/Dictionary:: of points. Overwrites all previous points and Dictionaries.
|
||||
|
||||
ARGUMENT:: d
|
||||
|
||||
METHOD:: shape
|
||||
Change the shape of the points, the options are \circle or \square. The default is \circle.
|
||||
|
||||
ARGUMENT:: sh
|
||||
(describe argument here)
|
||||
|
||||
METHOD:: pointSizeScale
|
||||
Scale all the points by a multiplier. See strong::pointSize_:: method above. The default is 1.
|
||||
|
||||
ARGUMENT:: ps
|
||||
(describe argument here)
|
||||
|
||||
METHOD:: close
|
||||

||||
METHOD:: parent
|
||||
|
||||

|
||||
|
||||
METHOD:: categories

|
||||
|
||||

TITLE:: FluidWaveform
|
||||
summary:: Buffer waveform display with optional overlays
|
||||
categories:: Libraries>FluidCorpusManipulation
|
||||
related:: Classes/FluidPlotter, Classes/FluidBufNoveltySlide, Classes/FluidBufOnsetSlice, Classes/FluidBufAmpSlice
|
||||
|
||||
DESCRIPTION::
|
||||
FluidWaveform plots a buffer with optional overlays such as slices derived from a FluCoMa Slicer.
|
||||
|
||||
CLASSMETHODS::
|
||||
|
||||
METHOD:: new
|
||||
Create a new instance of FluidWaveform.
|
||||
|
||||
ARGUMENT:: audio_buf
|
||||
The audio buffer to plot.
|
||||
|
||||
ARGUMENT:: slices_buf
|
||||
A buffer of slice indices. This will very likely be in the form of a buffer output from a FluCoMa slicer object. Currently this buffer must be only one channel, therefore it will not work with the output of link::Classes/FluidBufAmpGate::.
|
||||
|
||||
ARGUMENT:: bounds
|
||||
A link::Classes/Rect:: of where to place the FluidWaveform.
|
||||
|
||||
returns:: A new instance of FluidWaveform.
|
||||
|
||||
|
||||
INSTANCEMETHODS::
|
||||
|
||||
EXAMPLES::
|
||||
|
||||
code::
|
||||
|
||||
// load a sound to slice
|
||||
~drums = Buffer.read(s,File.realpath(FluidBufAmpSlice.class.filenameSymbol).dirname.withTrailingSlash ++ "../AudioFiles/Nicol-LoopE-M.wav");
|
||||
|
||||
// create a buffer to put indices into
|
||||
~indices = Buffer(s);
|
||||
|
||||
// do a slice analysis
|
||||
FluidBufAmpSlice.process(s,~drums,indices:~indices,fastRampUp: 10,fastRampDown: 2205,slowRampUp: 4410,slowRampDown: 4410,onThreshold: 10,offThreshold: 5,floor: -40,minSliceLength: 4410,highPassFreq: 20);
|
||||
|
||||
// plot the buffer with the indices overlayed
|
||||
FluidWaveform(~drums,~indices,Rect(0,0,800,200));
