Attributes
- alpha
Overall alpha value of the image. Ranges from 0.0 for transparent to 1.0 for full intensity.
alpha = Trait(1.0, Range(0.0, 1.0))
- draw_layer
Overrides PlotComponent; 2-D plots draw on the 'image' layer, underneath all decorations and annotations, and above only the background fill color.
draw_layer = 'image'
- index
The data source to use for the index coordinate.
index = Instance(GridDataSource)
- index_data_changed
Event fired when the index data changes. Subclasses can listen for this event and take appropriate steps (except for requesting a redraw, which is done in this class).
index_data_changed = Event
- index_mapper
Screen mapper for 2-D structured (gridded) index data.
index_mapper = Instance(GridMapper)
- index_mapper_changed
Event fired when the index mapper changes. Subclasses can listen for this event and take appropriate steps (except for requesting a redraw, which is done in this class).
index_mapper_changed = Event
- index_range
Convenience property for accessing the datarange of the mapper.
index_range = Property
- labels
Convenience property for accessing the plots labels.
labels = Property
- orientation
The direction that the first array returned by self.index.get_data() maps to.
- 'h': index maps to x-direction
- 'v': index maps to y-direction
orientation = Enum('h', 'v')
- value
The data source to use as value points.
value = Instance(ImageData)
- value_data_changed
Event fired when the value data changes. Subclasses can listen for this event and take appropriate steps (except for requesting a redraw, which is done in this class).
value_data_changed = Event
- x_mapper
Convenience property for accessing the x-direction mappers regardless of orientation. This provides compatibility with a number of tools.
x_mapper = Property
- y_mapper
Convenience property for accessing the y-direction mappers regardless of orientation. This provides compatibility with a number of tools.
y_mapper = Property

Methods
- __init__(self, **kwargs)
- map_data(self, screen_pts)
Maps a screen space point into the "index" space of the plot.
Implements the AbstractPlotRenderer interface.
- map_index(self, screen_pt, threshold = 2.0, outside_returns_none = True, index_only = False)
Maps a screen space point to an index into the plot's index arrays.
Implements the AbstractPlotRenderer interface. The index_only parameter is ignored because the index is intrinsically 2-D.
- map_screen(self, data_pts)
Maps an array of data points into screen space and returns it as an array.
Implements the AbstractPlotRenderer interface.
