Line 69 will fail if different (or non) tuple is unpacked.

This may happen if RGBT (transparency) is used (for example .png).

Fixed by changing line 36
From " img = Image.open(imgname)"
To " img = Image.open(imgname).convert ('RGB)"

It's hard to use Python 2 utilities with conda. (No easy way to run a command in specific virtual env AFAIK)

this happens on other images as well.

I've did something similar in c using fg+bg color and unicode character "upper half block"

U+2580 = ▀ = UPPER HALF BLOCK

to get double y resolution

Would you consider adding a switch that outputs old-style 16-color ANSI instead of 256-color?

Currently the ANSI output distorts the image, because each "pixel" is made up of a roughly 2x1 character.

Can the ANSI function be edited so that each pixel creates two of these characters instead of one? That should preserve the image aspect ratio

比如，一个**人的照片，头发都是黑色的，没必要这么生成html

<span color="#000">x</span><span color="#000">x</span><span color="#000">x</span>

更好的应该这样

<span color="#000">xxx</span>

This is a very nice utility for ASCII/ANSI art lovers. Do you intend on packaging it as its own module?

The code that maps rgb pixel inputs to ascii characters in the generate_grayscale_for_image() function can be written more efficiently by using matrix calculations from numpy. Currently, it looks like this:

for h in range(height):
      for w in range(width):
          rgba = pixels[w, h]
          if rgba[3] != 255 and bgcolor is not None:
              rgba = alpha_blend(rgba, bgcolor)
			# ...
        rgb = rgba[:3]
        string += color[int(sum(rgb) / 3.0 / 256.0 * 16)]
    string += "\n

The calculation int(sum(rgb) / 3.0 / 256.0 * 16) in the inner-body of the loop can be done on the pixels input variable when it's represented as a matrix. The code will likely become less readable, but a comment could be added to elaborate on the new calculations. With this optimization in place, I was able to build a program that converts webcam input images to ascii text with a really decent framerate.

Installed via pip install img2txt.py and venv/bin/ only has img2txt.py but not ansi.py or graphics_util.py.

Hi, thanks for this really cool tool !

I've noticed the version available on Pypi doesn't contains the range/xrange fix (and so is not compatible with Python 3). Could you release a new version to fix this ?

I have to admit I fix this by myself when trying the tool, then when I was about to send a PR about this, I realised it was already fixed in the repo ;-)
