EmTableModel

class emvis.models.EmTableModel(tableSource, **kwargs)

Implementation of TableModel for EM formats using a emc.Table object to parse the data.

__init__(tableSource, **kwargs)

Create a new instance of EmTableModel.

Parameters

tableSource –

Input from where table will be retrieved, it can be one of the following options:

• emc.Table: just a single table that will be used, not

  other tables will be loaded in this case

• string: This should be the path from where to read

  the table(s). The first table will be loaded by default.

• tuple (string, string): Here you can specify the path and

  the name of the table that you want to be loaded by default.

Keyword Arguments

Provide an ImageManager that can be used (imageManager=value) – to read images referenced from this table.

getColumnsCount()

Return the number of columns.

getData(row, col)

Return the data (array like) for the item in this row, column. Used by rendering of images in a given cell of the table.

getRowsCount()

Return the number of rows.

getValue(row, col)

Return the value of the item in this row, column.

iterColumns()

Iterated over the current ColumnInfo’s of the model.

EmStackModel

class emvis.models.EmStackModel(path, **kwargs)

The EmStackModel class provides the basic functionality for image stack. The following methods are wrapped directly from SlicesModel:

• getDim

• getData

• getLocation

• getImageModel

__init__(path, **kwargs)

Constructs an EmStackModel. Note that you can specify the path and/or SlicesModel. :param path: (str) The image path :param kwargs:

• slicesModel(SlicesModel) The SlicesModel from which this

  EmStackModel will be created.

• columnName(str) The column name for image column.

  if columnName is None, then ‘Image’ will be used.

• imageManager=value Provide an ImageManager that can be used

  to read images referenced from this table.

getData(i=-1)

Return a 2D array of the slice data. i should be in -1 or (0, n-1). -1 is a special case for returning the whole data array.

getLocation()

Returns the image location(the image path).

EmVolumeModel

class emvis.models.EmVolumeModel(path, data=None, **kwargs)

The EmVolumeModel class provides the basic functionality for image volume

__init__(path, data=None, **kwargs)

Constructs an EmVolumeModel. :param path: (str) The volume path :param data: (numpy array) The volume data :param kwargs:

• imageManager=value Provide an ImageManager that can be used

  to read images referenced from this table.

EmListModel

class emvis.models.EmListModel(files, **kwargs)

The EmListModel class provides the basic functionality for create models or read data from the list of file paths

__init__(files, **kwargs)

Create an EmListModel :param files: (list) A list of file path :param kwargs:

• imageManager(ImageManager) The ImageManager instance that can

  be used to read images referenced from this list

• imagePrefixes: (list) The list of image prefixes

getData(row, col=0)

Return the data (array like) for the item in this row, column. Used by rendering of images in a given cell of the table.

getModel(row)

Return the model for the given row

getRowsCount()

Return the number of rows.

getValue(row, col)

Return the value of the item in this row, column.

iterColumns()

Iterated over the current ColumnInfo’s of the model.
