slitflow.fig.image module

class Gray(info_path=None)

Bases: Figure

Create pseudo color map from a gray scale Image object.

Caution

The image should be split into a single frame image. In other words, the shape of reqs[0] in process() should be (1, height, width).

Parameters:

• reqs[0] (Image) – Image to create image Figure. Required params; img_size, pitch.

• param["lut_limits"] (list of float) – Lower and upper limit of LUT.

• param["cmap"] (str, optional) – Color map name for matplotlib.pyplot.imshow(). Defaults to “viridis”.

Returns:

matplotlib Figure object

Return type:

Figure

set_info(param={})

Copy info from reqs[0] and add params.

static process(reqs, param)

Create pseudo color map from a gray scale image array.

Parameters:

• reqs[0] (numpy.ndarray) – Image to create image figure.

• param["lut_limits"] (list of float) – Lower and upper limit of LUT.

• param["cmap"] (str) – Color map name for matplotlib.pyplot.imshow().

Returns:

matplotlib Figure containing pseudo color image
