Bases: object

Base class for 2D views on spatial images

Provide a QPixmap when asked to

data_coordinates(x_pix, y_pix)

• y_pix (int)

Returns Type:

int,int

image()

Get currently displayed image

Returns Type:array

pixmap_coordinates(inds)

Convert coordinates expressed in data space into a point in the pixmap space

Parameters:

• inds (tuple of int) - coordinate of a point in data space

  e.g. i,j or i,j,k

Returns Type:

int,int

Returns Type:float,float

resolution()

Return resolution of the pixmap

Returns Type:float,float

rotate(orient)

Rotate view 90 degrees

Parameters:

• orient (int) - orientation of rotation

  • if orient == 1, rotation clockwise
  • if orient == -1, rotation counterclockwise

set_image(img)

Set an image to display

Parameters:

• im (array)

set_palette(palette)

Set the palette

Parameters:

• palette (list of int)

class image.gui.pixmap_view.PixmapStackView(img=None, palette=None)

Bases: image.gui.pixmap_view.PixmapView

Pixmap view of a spatial image as a stack of images

current_slice()

Index of the currently displayed slice

Returns Type:int

data_coordinates(x_pix, y_pix, axis=0)

Convert coordinates expressed in the pixmap into coordinates expressed as indices in the data space.

Parameters:

• x_pix (int)
• y_pix (int)

Returns Type:

int,int,int

nb_slices()

Number of slices in the stack

Returns Type:int

pixmap()

Return a pixmap representation of the spatial image

pixmap_coordinates(i, j)

Convert coordinates expressed in data space into a point in the pixmap space

Parameters:

• inds (tuple of int) - coordinate of a point in data space

  e.g. i,j or i,j,k

Returns Type:

int,int

rotate(orient)

Rotate view 90 degrees

Parameters:

• orient (int) - orientation of rotation

  • if orient == 1, rotation clockwise
  • if orient == -1, rotation counterclockwise

set_current_slice(ind)

Change current displayed slice

Parameters:

• ind (int) - index of the slice in the data array

set_image(img)

Set an image to display

Parameters:

• im (array)

set_palette(palette, axis=2)

Set the palette

Warning

will cast color value to uint32

Parameters:

• palette (list of int)
