将JPG图像添加到folium popup

标签: python popup folium

我尝试将图像添加到folium弹出窗口,但失败了。我使用python 2.7版本和folium 0.50版本。

实际上,我在其他帖子中提到了页面提及,但它仍然不起作用

import folium

import base64

m = folium.Map(location = [33, -97], zoom_start = 6, tiles = "Mapbox Bright")

encoded = base64.b64encode(open('IMG_1769.JPG', 'rb').read()).decode()

html = '<img src="data:image/jpeg;base64,{}">'.format

iframe = folium.IFrame(html(encoded), width=632+20, height=420+20)

popup = folium.Popup(iframe, max_width=2650)

marker = folium.Marker([30,-100], popup=popup).add_to(m)

m.add_child(marker)

m.save("test.html")

我一直关注this example,它(几乎)为我工作。由于encoded变量是字节数组而不是字符串,因此无法正确进行 base64解码绘图,从而生成了 b'iVBOR 标头,而不是 iVBOR 标头(PNG标头的base64版)。

html(encoded)替换为html(encoded.decode('UTF-8'))可以解决此问题。

这是输出。

Folium Heatmap with Graph


这是代码段。

    fig, ax = plt.subplots(figsize=(width, height))
    ax = subdf.plot(x='date', y='temperature', ax=ax, legend=False)
    ax.set_ylabel('Temp (°C)')
    png = '/tmp/temperatures_{}.png'.format(counter)
    fig.savefig(png, dpi=resolution)

    encoded = base64.b64encode(open(png, 'rb').read())



    html = '<img src="data:image/png;base64,{}">'.format
    #print(20*'-',encoded.decode('UTF-8'))
    iframe = IFrame(html(encoded.decode('UTF-8')), width=(width*resolution)+20, height=(height*resolution)+20)
    popup = folium.Popup(iframe, max_width=2650)

    icon = folium.Icon(color="red", icon="ok")
    marker = folium.Marker([lat, lon], popup=popup, icon=icon)
    marker.add_to(marker_cluster)

 import base64
 from folium import IFrame

 #Add Marker
 encoded = base64.b64encode(open('mypict.jpg', 'rb').read())
 html = '<img src="data:image/png;base64,{}">'.format
 iframe = IFrame(html(encoded.decode('UTF-8')), width=400, height=350)
 popup = folium.Popup(iframe, max_width=400)

 folium.Marker(location=[43.591545, 39.728056], tooltip=html, popup = popup, 
 icon=folium.Icon(color = 'gray')).add_to(map)
