freestyle.utils.ContextFunctions.load_map(file_name, map_name, num_levels=4, sigma=1.0)#

Loads an image map for further reading.

Parameters:

  • file_name (str) – The name of the image file.

  • map_name (str) – The name that will be used to access this image.

  • num_levels (int) – The number of levels in the map pyramid (default = 4). If num_levels == 0, the complete pyramid is built.

  • sigma (float) – The sigma value of the gaussian function.

freestyle.utils.ContextFunctions.read_complete_view_map_pixel(level, x, y)#

Reads a pixel in the complete view map.

Parameters:

  • level (int) – The level of the pyramid in which we wish to read the pixel.

  • x (int) – The x coordinate of the pixel we wish to read. The origin is in the lower-left corner.

  • y (int) – The y coordinate of the pixel we wish to read. The origin is in the lower-left corner.

Returns:

The floating-point value stored for that pixel.

Return type:

float

freestyle.utils.ContextFunctions.read_directional_view_map_pixel(orientation, level, x, y)#

Reads a pixel in one of the oriented view map images.

Parameters:

  • orientation (int) – The number telling which orientation we want to check.

  • level (int) – The level of the pyramid in which we wish to read the pixel.

  • x (int) – The x coordinate of the pixel we wish to read. The origin is in the lower-left corner.

  • y (int) – The y coordinate of the pixel we wish to read. The origin is in the lower-left corner.

Returns:

The floating-point value stored for that pixel.

Return type:

float

freestyle.utils.ContextFunctions.read_map_pixel(map_name, level, x, y)#

Reads a pixel in a user-defined map.

Parameters:

  • map_name (str) – The name of the map.

  • level (int) – The level of the pyramid in which we wish to read the pixel.

  • x (int) – The x coordinate of the pixel we wish to read. The origin is in the lower-left corner.

  • y (int) – The y coordinate of the pixel we wish to read. The origin is in the lower-left corner.

Returns:
