Introduction

This is a program written in Haskell that will load an image and convert the image into ASCII art using a special formula to make it look extremely similar to the original image.

-Need to make sure the program works still, last updated in march 2020

Requirements:

you will need to install the package "bmp-1.2.6.3".

Instructions:

First, load the image by calling the loadBitmap function on the image. For example, if the image is called "flower" you would do loadBitmap "flower.bmp" This would result in a two-dimensional list of pixels as a return value. This allows you to call the displayImage function to see the end result.

displayImage ".-+*#" True (loadBitmap "sample_image_to_search.bmp") This command would load the image and convert it so that . would be used for white pixels, and # is used for black pixels. The characters in between the first and last character would be used for different shades of grey accordingly. In this case, -+* would be used for 3 shades of grey... 75%, 50%, & 25%. The algorithm I made will automatically split the shades of grey into a balanced amount. For example, if we had .$%^&# then . & # would be used for white and black pixels respectively and then $%^& would be split into 4 quadrants equally instead of 3. The true/false paramteres in the function switches white and blacks meaning the first pixel would be black instead of white and the last white instead of black

The showAsASCIIArt function will allow you to view the result of your function. it should be called on the previous function ran to view the results.

For instance: showAsASCIIArt (displayImage ".-+*#" True (loadBitmap "sample_image_to_search.bmp"))

Note:

this program only works with bitmap files (.bmp)

This is outdated and needs to be updated I believe -- also need a haskell refresher
