# This notebook demonstrates basic usage of the firefly_client API.
# 
# Note that it may be necessary to wait for some cells (like those displaying an image) to complete before executing later cells.

# ## Setup

# Imports for Python 2/3 compatibility

# In[ ]:


from __future__ import print_function, division, absolute_import


# Imports for firefly_client

# In[ ]:


from firefly_client import FireflyClient


# In this example we use the irsaviewer application for the server.

# In[ ]:


url='http://127.0.0.1:8080/firefly'


# Instantiate `FireflyClient`.

# In[ ]:


fc = FireflyClient(url)


# ## Download some data

# Download a sample image and table.
# 
# We use astropy here for convenience, but firefly_client itself does not depend on astropy.

# In[ ]:


import astropy.utils.data


# Download a cutout of a WISE band 1 image.

# In[ ]:


image_url = ('http://irsa.ipac.caltech.edu/ibe/data/wise/allsky/4band_p1bm_frm/6a/02206a' + 
            '/149/02206a149-w1-int-1b.fits?center=70,20&size=200pix')
filename = astropy.utils.data.download_file(image_url, cache=True, timeout=120)


# ## Display tables and catalogs

# Open a browser to the firefly server in a new tab. The browser open only works when running the notebook locally, otherwise a link is displayed.

# In[ ]:


localbrowser, browser_url = fc.launch_browser()


# Display the web browser link

# In[ ]:


fc.display_url()


# A local file can be uploaded to the server and then displayed.

# In[ ]:


imval = fc.upload_file(filename)
status = fc.show_fits(file_on_server=imval, plot_id="region test", title='text region test')


# Add region data containing text region with 'textangle' property
