4/5/2024 0 Comments Easy ascii art java code![]() ) The last time I did this was about tens years ago. You can even use anti-aliasing for effect. Image processing could be parallelized for performance improvent, try it and measure the gain to see if is worth it. 2 Answers Sorted by: 50 You can write text to a bitmap in any font you want and scan the bitmap to produce the ASCII art.Try to preprocess the image to get better results (improve contrast, use edge detection, etc.). ![]() Research and try to implement more image comparison algorithms The Java ASCII Art Generator is a Java class that provides functions to generate ASCII art of smiley faces, hearts, and trees.Here are some sample images generated with various parameters: Try load an image, and print out the rgb color, you will noticed that different color has different code. This is the idea to generate the ASCII art graphic. convertImage ( portraitImage ), "png", new File ( "ascii_art.png" )) // string converter, output to console System. What is -1677216 The color code, in this case all colors -1677216 are replaced with empty. Since it was built over a few hours during the weekend, it is not optimal but it was a fun experiment. ![]() read ( new File ( "image.png" )) // initialize converters AsciiToImageConverter imageConverter = new AsciiToImageConverter ( cache, new ColorSquareErrorFitStrategy ()) AsciiToStringConverter stringConverter = new AsciiToStringConverter ( cache, new StructuralSimilarityFitStrategy ()) // image output ImageIO. I present you a very simple ascii art generator written in Java with configurable font and contrast. BOLD, 6 )) // load image BufferedImage portraitImage = ImageIO. Each pixel in the image is like a paint swatch and each ASCII character is like a brush stroke. initialize cache AsciiImgCache cache = AsciiImgCache. Think of it like a color-by-number painting. Since a code snippet is worth a thousand words, I will show you the whole process in action that should wrap up all the pieces: There are two implementations currently: AsciiToImageConverter and AsciiToStringConverter - which as you probably guessed, produce image and string output. However, it doesn’t know how to create the concrete ascii art - it needs to be subclassed. This is the hearth of the process and it contains all the logic for tiling source image and utilizing concrete implementations for calculating character best fit. I experimented a bit with it and implemented a version that seemed to produce the best results for this case. I will not get into much details about how it works, you can read more on Wikipedia if you want to know more. The structural similarity (SSIM) index algorithm claims to reproduce human perception and its aim is to improve on traditional methods like MSE. Where n is the number of pixels, and C and T are pixels from character and tile image respectively. Very simple to understand, it compares every pixel and calculates Mean squared error of the grayscale differences. Each character will be compared and the one that returns the lowest error will be selected.Ĭurrently there two implementations available: ColorSquareErrorFitStrategy and StructuralSimilarityFitStrategy. The implementation should compare two images and return a float error. Once complete, the Cells would have their sibling Cells set by the addDownUpLeftRightToCells method.Float calculateError ( final GrayscaleMatrix character, final GrayscaleMatrix tile ) The first parse would create Cells with just the type, xAxis and yAxis set.Ĭell( type = fromChar(character.toChar()), The ASCII art was parsed a line at a time creating the List of List of Cells. This design made it actually possible for me to write the code (which was a good sign!). I considered this, but thought that it was more complex than just having a mutable Cell class as follows: From that, a copy could be made each time a new sibling needed to be set. One option would be to create a "half baked" Cell which had it's sibling cells missing (null) at first. a recursive data structure), you couldn't create a cell until you have created every other cell required for the entire maze. Given that a Cell consisted of four other Cells (i.e. The original idea was to have a Cell consist of immutable attributes (i.e. Each Maze consisted of a List of a List of Cells. I wanted to created a Maze from my ASCII art input as shown above.

Whilst trying to make all of my objects nice and immutable, I hit a problem.
