resolve_1D#

stimupy.utils.resolution.resolve_1D(length=None, visual_angle=None, ppd=None, round=True)#

Resolves the full resolution, for 2 givens and 1 unknown

A resolution consists of a visual size in degrees, a shape in pixels, and specification of the number of pixels per degree. Since there is a strict geometric relation between these, shape = visual_size * ppd, if two are given, the third can be calculated using this function.

This function resolves the resolution in a single dimension.

Parameters:

  • length (Number, length in pixels, or None (default))

  • visual_angle (Number, length in degrees, or None (default))

  • ppd (Number, pixels per degree, or None (default))

Returns:

  • length (int, length in pixels)

  • visual_angle (float, length in degrees)

  • ppd (float, pixels per degree)
