ImageWidget as QtWidget

This example opens multiple windows to show multiple ImageWidgets.

# test_example = false

import numpy as np
from PyQt6 import QtWidgets
import fastplotlib as fpl
import imageio.v3 as iio


images = np.random.rand(100, 512, 512)

# fastplotlib and wgpu will auto-detect if Qt is imported and then use the Qt canvas
iw = fpl.ImageWidget(images)
widget = iw.show()
widget.resize(800, 800)

# another image widget with multiple images
images_list = [np.random.rand(100, 512, 512) for i in range(4)]

iw_mult = fpl.ImageWidget(
    images_list,
    cmap="viridis"
)
widget_multi = iw_mult.show()
widget_multi.resize(800, 800)

# image widget with rgb data
rgb_video = iio.imread("imageio:cockatoo.mp4")
iw_rgb = fpl.ImageWidget(rgb_video, rgb=[True], figure_kwargs={"size": (800, 500)})
iw_rgb.show()

fpl.run()

# You can also use Qt interactively/in a non-blocking manner in notebooks and ipython
# by using %gui qt and NOT calling `fpl.run()`, see the user guide for more details
