[Image Processing] - ASCII-inator
« on: February 05, 2013 »
Just for fun, I thought I'd try to build an image-to-ASCII-art converter in JS.

To use it, you'll need to unzip the archive, and place a GIF, JPG or PNG file in the same directory as the HTM file.
Next open the program under Firefox or IE9 and type the complete file-name of the image into the form.
Then press the Generate button. If the file-name is correct, the image should be converted into ASCII art.

It's only been successfully tested under Firefox and IE9. Chrome doesn't work due to a false-positive in its default security settings.

(edit) I have improved the code for better contrast handling, but only slightly.

Here's an output sample:
Code: [Select]
                               ¤xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx•                                     
                               ¤xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx•

            ¤MMMMMMMMMMMMMMMMMMMMMMMM¤                        ¤MMMMMMMMMMMMMMMMMMMMMMMM¤           

I may need to make some adjustments.

(edit) I've updated again - I should really do more testing before I release :)
Charset 10 is now the default, non-existent files are handled better, and you can now choose between 3 scaling options. Also, the courier font aspect ratio is better catered for.
