fsleyes.displaycontext.sceneopts
This module provides the SceneOpts
class, which contains display
settings used by CanvasPanel
instances.
- class fsleyes.displaycontext.sceneopts.SceneOpts(panel)[source]
Bases:
__main__.docbuilder.run.<locals>.MockClass
The
SceneOpts
class defines settings which are used byCanvasPanel
instances.Several of the properties of the
SceneOpts
class are defined in theSliceCanvasOpts
class, so see its documentation for more details.- showCursor = <MagicMock name='mock.Boolean()' id='4118222112'>
- zoom = <MagicMock name='mock.Percentage()' id='4117573488'>
- bgColour = <MagicMock name='mock.Colour()' id='4117565200'>
- cursorColour = <MagicMock name='mock.Colour()' id='4117565248'>
- renderMode = <MagicMock name='mock.Choice()' id='4117565296'>
- highDpi = <MagicMock name='mock.Boolean()' id='4117565344'>
- fgColour = <MagicMock name='mock.Colour()' id='4118213728'>
Colour to use for foreground items (e.g. labels).
Note
This colour is automatically updated whenever the
bgColour
is changed. But it can be modified independently.
- showColourBar = <MagicMock name='mock.Boolean()' id='4118803744'>
If
True
, and it is possible to do so, a colour bar is shown on the scene.
- colourBarLocation = <MagicMock name='mock.Choice()' id='4118567808'>
This property controls the location of the colour bar, if it is being shown.
- colourBarLabelSide = <MagicMock name='mock.Choice()' id='4118567808'>
This property controls the location of the colour bar labels, relative to the colour bar, if it is being shown.
- colourBarSize = <MagicMock name='mock.Percentage()' id='4117953264'>
Size of the major axis of the colour bar, as a proportion of the available space.
- labelSize = <MagicMock name='mock.Int()' id='4117859440'>
Font size used for any labels drawn on the canvas, including orthographic labels, and colour bar labels.
- performance = <MagicMock name='mock.Choice()' id='4118567808'>
User controllable performance setting.
This property is linked to the
renderMode
property. Setting this property to a low value will result in faster rendering time, at the cost of increased memory usage and poorer rendering quality.See the
__onPerformanceChange()
method.
- __annotations__ = {}
- __module__ = 'fsleyes.displaycontext.sceneopts'
- __init__(panel)[source]
Create a
SceneOpts
instance.This method simply links the
performance
property to therenderMode
property.
- movieSyncRefresh = <MagicMock name='mock.Boolean()' id='4118803744'>
Whether, when in movie mode, to synchronise the refresh for GL canvases. This is not possible in some platforms/environments. See
CanvasPanel.movieSyncRefresh
.
- property defaultMovieSyncRefresh
In movie mode, the canvas refreshes are performed by the __syncMovieRefresh or __unsyncMovieRefresh methods of the CanvasPanel class. Some platforms/GL drivers/environments seem to have a problem with separate renders/buffer swaps, so we have to use a shitty unsynchronised update routine.
These heuristics are not perfect - the movieSyncRefresh property can therefore be overridden by the user.
- property panel
Return a reference to the
CanvasPanel
that owns thisSceneOpts
instance.
- _onPerformanceChange(*a)[source]
Called when the
performance
property changes.This method must be overridden by sub-classes to change the values of the
renderMode
property according to the new performance setting.
