Static functions

Functions that work with Frame objects.

Everything related to making LinMaze Frames.

Frame.multi_make(list_of_frames)

Renders a list of frames with multiprocessing.

Parameters:list_of_frames ([Frame]) – A list of Frame objects that sould be rendered. Returns:A list of rendered Frames.

Frame.transition(left, right, transition_width)

Takes two 2 dimensional matrices representing a grayscale image and returns them with a smooth transition of given width between them.

Parameters:

• left (np.array with ndim=2) – The image on the left.
• right (np.array with ndim=2) – The image on the right.
• transition_width (int) – The width of the smooth transition.

Frame.combine(list_of_frames)

Makes a Frame that is a combination of a list of Frames.

Parameters:list_of_frames ([Frame]) – A list of Frame objects without transitions. Returns:Frame

Abstract Frame classes

Abstract classes for all Frames to inherit from.

Frame

class Frame.Frame(width, height, rgb=(1, 1, 1))

The visual component of the blocks that the mouse navigates in.

Parameters:

• width (int) – The width of the Frame in pixels.
• height (int) – The height of the Frame in pixels.
• rgb ((float, float, float)) – The Red, Green and Blue levels of the Frame.

static ext_make(frame)

Tries to load the given Frame from cache or makes it and returns the rendered Frame.

make()

Renders the Frame.

make_img()

Makes a PIL Image of the Frame.

make_texture()

Makes the Frame’s texture field that stores RGB data to be used as an OpenGL texture .

mirror()

Horizontally mirrors the Frame

save_img(filename)

Saves the bitmap image of the Frame with the given filename.

Parameters:filename (str) – The filename the image should be saved as.

show_img()

Displays the bitmap image of the Frame.

Random Frame

class Frame.RandomFrame(width, height, seed)

Bases: Frame.Frame

Abstract class all randomly generated Frames inherit from.

Parameters:seed – The seed of the random number generator

Wave Frame

class Frame.WaveFrame(width, height, wavelength, angle)

Bases: Frame.Frame

Generic grating Frame, for more specific ones to inherit form.

Parameters:

• wavelength (int) – The wavelength of the grating in pixels, ie. the distance between the middles of the white portions.
• angle (float) – The angle of the graing where 0 is vertical.

make()

Renders the Frame.

static wave_func(val)

Trigonometric function for a sinusoidal wave.

Specific Frames

All the different types of Frames you can make.

Parameters:filename (string) – The name of the file the Frame should be made from.

make()

Renders the Frame.

make_texture()
