fsleyes.plugins.profiles.samplelineprofile

This module provides the SampleLineProfile class, an interaction Profile for OrthoPanel views, which is used by the SampleLinePanel.

class fsleyes.plugins.profiles.samplelineprofile.SampleLineProfile(viewPanel, overlayList, displayCtx)

Bases: fsleyes.profiles.orthoviewprofile.OrthoViewProfile

The SampleLineProfile class is a Profile for the OrthoPanel class, which allows the user to draw a line on a canvas. The SampleLinePanel will then sample values along that line from the currently selected overlay, and display them on a plot.

static tempModes()

Returns the temporary mode map for the SampleLineProfile, which controls the use of modifier keys to temporarily enter other interaction modes.

static altHandlers()

Returns the alternate handlers map, which allows event handlers defined in one mode to be re-used whilst in another mode.

__init__(viewPanel, overlayList, displayCtx)

Create a SampleLineProfile.

Parameters

• viewPanel – An OrthoPanel instance.

• overlayList – The OverlayList instance.

• displayCtx – The DisplayContext instance.
