Increase resolution with word-cloud and remove empty border

Question

I am using word cloud with some txt files. How do I change this example if I wanted to 1) increase resolution and 2) remove empty border.

#!/usr/bin/env pyt

If you are trying to use an image as a mask, make sure to use a big image to get better image quality.. I spent hours figuring this out.

Heres an example of a code snippet I used

mask = np.array(Image.open('path_to_your_image'))
image_colors = ImageColorGenerator(mask)
wordcloud = WordCloud(width=1600, height=800, background_color="rgba(255, 255, 255, 0)", mask=mask
                     ,color_func = image_colors).generate_from_frequencies(x)

# Display the generated image:
plt.figure( figsize=(20,10) )
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis("off")
