The background of a logo or text element is always black. Specifying the background color has no effect.

import numpy as np
from PIL import Image

from pydecorate import DecoratorAGG
import aggdraw


# Create sample image
im = Image.fromarray(np.random.randint(low=0, high=255, size=(480, 640), dtype=np.uint8))

# Add logo & text
deco = DecoratorAGG(image=im)
font = aggdraw.Font('black', '/usr/share/fonts/dejavu/DejaVuSansCondensed.ttf', size=48)
deco.add_logo('mylogo.png', bg='white')
deco.add_text('Test Label', font=font, bg='yellow', height=None)

im.save('decorated.png')

Result:

Expected: White/yellow background for logo/text.

Environment: pydecorate-0.1.0, aggdraw-1.3. It worked fine with aggdraw-1.1-20051010.

With this piece of code

    img = Image.open(imgfile)
    dc = DecoratorAGG(img)
    dc.add_logo(smhilogo, height=80.0)

...I get some deprecation warnings:

/local_disk/src/pydecorate/pydecorate/__init__.py:270: DeprecationWarning: 
tostring() is deprecated. Please call tobytes() instead.
  return aggdraw.Draw(image)


Code works fine, but we need to fix this for the future!

Original issue reported on code.google.com by [email protected] on 13 Nov 2014 at 11:59

An error occurred during the use of pydecorate, and I did not go to the custom font-related configuration.
all are configured by default.

I am working with pydecorate to add text and colorbar to images . I am working with this tutorial:
https://pydecorate.readthedocs.io/en/latest/usage.html
I am using this code:

from PIL import Image
from pydecorate import DecoratorAGG
import aggdraw
from trollimage.colormap import rdbu
import matplotlib.pyplot as plt

filepath = r'path\to\file.tif
img = Image.open(filepath)

dc = DecoratorAGG(img)
dc.write_vertically() 
dc.align_left()

font=aggdraw.Font("black", r'C:\Windows\Fonts\times.ttf', size = 115)
dc.add_text(
    'text line 1\nline 2 or text\nThis is also text', 
            font = font)
dc.add_scale(rdbu, extend = True)

imgplot = plt.imshow(img) # image will not display in plots window.

This creates text and a colorbar like I want, but the width of the colorbar seems to be dictated by the width of the text above it. Is there some way to manually set the width of the colorbar?
Also, is there some way to display the colorbar next to the image, as opposed to on the edge of the image? Should I do this by simply adding a border?
Thanks for your help.

Probably due to newer numpy.

Warning from the test suite:

pydecorate\decorator_agg.py:21

I also noticed it is not currently listed as a dep, though it is currently required.

Due to this line

(Image.ANTIALIAS was removed.)

Exception:

AttributeError: module 'PIL.Image' has no attribute 'ANTIALIAS'

The font parameter for add_text does not take a font object as parameter as described by the documentation, but rather a string object describing the path to the font to use.

Font parameters such as size are then passed as additional optional parameters in the add_text call. An example for correct usage would be:

dc.add_text("IR Temperature [C]", font="/usr/share/fonts/truetype/dejavu/DejaVuSansMono-Bold.ttf", font_size=12, height=25)
