WaveData module

class lys.widgets.canvas.interface.WaveData.WaveData(canvas, wave, axis)[source]

Bases: CanvasPart

Interface to access wave data in the canvas.

This class is inherited by Line.LineData, Image.ImageData, RGB.RGBData, Vector.VectorData, and Contour.ContourData.

Instance of WaveData is automatically generated by display or append methods.

getAxis()[source]

Get the axis to which the data was added.

Returns:: The axis (‘BottomLeft’, ‘TopLeft’, ‘BottomRight’, or ‘TopRight’).
Return type:: str

getFilter()[source]

getFilteredWave()[source]

Get the wave to which offset and filter have been applied.

Returns:: The filtered wave.
Return type:: Wave

getName()[source]

Get the name of the wave data.

Returns:: The name.
Return type:: str

getOffset()[source]

Get the offset to the data.

See setOffset() for detail.

Returns:: The offset in the form of (x0, y0, x1, y1).
Return type:: tuple of length 4 float

getVisible()[source]

Get the visibility of the data.

Returns:: The visibility of the data.
Return type:: bool

getWave()[source]

Get the wave.

Returns:: The wave.
Return type:: Wave

getZOrder()[source]

Get the z order of the data.

Returns:: The z order.
Return type:: int

loadAppearance(appearance)[source]

Load appearance from dictionary.

Users can save/load appearance of data by save/loadAppearance methods.

Parameters:: appearance (dict) – dictionary that include all appearance information, which is usually generated by saveAppearance() method.

modified: This pyqtSignal is emimtted when the data is changed.

saveAppearance()[source]

Save appearance from dictionary.

Users can save/load appearance of data by save/loadAppearance methods.

Returns:: dictionary that include all appearance information.
Return type:: dict

setFilter(filter=None)[source]

Apply filter to the data.

Parameters:: filter (filterr) – The filter. See lys.filters.filter.FilterInterface.FilterInterface

setName(name)[source]

Set the name of the data.

Parameters:: name (str) – The name of the data.

setOffset(offset)[source]

Set the offset to the data.

The data is offset as x’=x*x1+x0 and y’=y*y1+y0.

Parameters:: offset (tuple of length 4 float) – The offset in the form of (x0, y0, x1, y1).

setVisible(visible)[source]

Set the visibility of the data.

Parameters:: visible (bool) – The visibility of the data.

setZOrder(z)[source]

Set the z order of the data.

Parameters:: z (int) – The z order.
