This control is view-only. It is not interactive.
Images are currently loaded via the Graph API. This is quite inefficient and will be replaced with a more robust system in the future. For now, please be mindful with image sizes.
Example
from mirmod.controls import Image
from mirmod import miranda
import json
import base64
@wob.init()
def init(self):
self.image_path = None
@wob.receiver("value", "Image Path")
def set_image(self, i):
self.image_path = i
@wob.receiver("state","image",control=Image(),hidden=True,connectable=False)
def get_image(self,plotly_data):
pass
@wob.execute()
def execute(self):
# Load image from disk
image = None
if self.image_path:
with open(self.image_path, "rb") as image_file:
image = image_file.read()
# generate base64 url
image = "data:image/png;base64," + base64.b64encode(image).decode("utf-8")
ecx = miranda.get_execution_context()
ob = ecx.get_current_wob()
sc = ecx.get_security_context()
miranda.update_api(
sc, ob,
"RECEIVER", "image", "state",
value=image, connectable=False, hidden=True
)
miranda.notify_gui(sc, json.dumps({
"action": "update[VIEW]",
"data": { "id": ob.id, "metadata_id" : ob.metadata_id }
}))
