Matplotlib imshow和kivy [英] Matplotlib imshow and kivy

问题描述

我有一个3D numpy数组，表示3D断层图像I = [i，j，k].

I have a 3D numpy array, representing a 3D tomographic image I = [i,j,k].

我开始学习kivy，因为我需要做一个简单的GUI，该GUI包括一个用于3D(s = [i，:，:])图像的每个切片的2D图像查看器和一个在平面上移动的切片器.

I started to learn kivy as I need to do a simple GUI consisting of a 2D image viewer for each slice of the 3D (s = [i,:,:]) image and a slicer to move across planes.

我通常通过matplotlib进行所有可视化，我坚信最简单的方法是将matplotlib连接到kivy.我该怎么做? 我看到另一个问题，它提出了一个类似的问题，但仅具有plot函数，该方法似乎不适用于imshow. (如何开始/使用matplotlib在猕猴桃中).

I usually perform all visualization via matplotlib and I tough that the easiest way will be to connect matplotlib to the kivy. How can I do it? I saw another question which ask a similar question, but only with the plot function, and the methodology does not seems to work for imshow. (How to get started/use matplotlib in kivy).

有什么建议吗?

谢谢

推荐答案

有关详细信息，请参阅示例.

Please refer to the example for details.

from kivy.garden.matplotlib.backend_kivyagg import FigureCanvasKivyAgg
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
import matplotlib.pyplot as plt
import matplotlib.image as mpimg


img = mpimg.imread('ac013.JPG')
lum_img = img[:, :, 0]
plt.imshow(lum_img, cmap="nipy_spectral")
plt.colorbar()


class TestApp(App):
    title = "Kivy Garden Matplolib & imshow()"

    def build(self):
        box = BoxLayout()
        box.add_widget(FigureCanvasKivyAgg(plt.gcf()))
        return box


if __name__ == "__main__":
    TestApp().run()
