This little project will try to read in .bmp files and convert them to lovely ASCII art with the given
set of characters ordered from "fullest" to "empty" (black to white).
The ASCII art is saved externally in the specified file or simply printed in the console. I recommend piping the output to a file as most consoles will not display the ASCII art correctly. Make sure to open the output as UTF-8 or otherwise it may not work.
This will only work for 24 bit bitmap images, so transparency is not allowed for now. Furthermore, this assumes the origin at the lower left corner of the image which may be changed later on.
To use this, simply clone this repository by doing
git clone https://github.com/xkevio/BMPtoASCII.git
and then compile the project with any compiler that supports #pragma pack.
First, create a build folder in the project in which the binary will go.
Then, head into that directory and type cmake ...
To finally build the binary, type make.
If you do not use CMake or do not wish to install it, you can also compile this project manually with
your favorite compiler. With gcc it could look like this for example:
g++ -o BMPtoASCII main.cpp bmp_file.cpp
Now you can use the project by simply typing
BMPtoASCII[.exe] img.bmp in your terminal.
