A tool that converts images to Braille text and vice versa.
You can clone this repo, copy the contents of ImageToBraille.java or download the jar file.
Call the jar file like this:
java -jar ImageToBraille.jar C:\path\to\image.png <arguments>
| Argument | Role |
|---|---|
<path> |
If the target is a text file, then the output will be an image, otherwise the output will be the braille text. |
noinvert |
Dots correspond to dark pixels, used for white backgrounds. |
width <value> height <value> |
Size the image before processing. You must specify both width and height, not just one of them. |
contrast <number between 1 and 254> |
Sets the luminance at which the pixel becomes darker or lighter. |
output <path to file> |
Writes the result to a text file. |
You can add a dash before the arguments but this will not change anything.
As a util class, you can use static access to methods.
Here are a few examples:
List<String> lines = ImageToBraille.fromPath("C:/path/to/image.png", true, 128);You can also resize the image:
List<String> lines = ImageToBraille.fromPath("C:/path/to/image2.png", 200, 250, false, 156);Or use an image object:
BufferedImage image = ImageIO.read(new File("C:/path/to/image3.png");
List<String> lines = ImageToBraille.fromPath(image, false, 156);String brailleLines = "⠀⠀⠀⠀⠀⠀⢀⣠⣤⣶\n" +
"⣀⣀⣤⣴⣾⣿⣿⣿⣿\n";
BufferedImage image = ImageToBraille.fromBraille(brailleLines);Also works if brailleLines is a list of string:
List<String> brailleLines = new ArrayList<String>();
brailleLines.add("⠀⠀⠀⠀⠀⠀⢀⣠⣤⣶");
brailleLines.add("⣀⣀⣤⣴⣾⣿⣿⣿⣿");
// More lines
BufferedImage image = ImageToBraille.fromBraille(brailleLines);And then you can save it with this (but you can do it differently):
ImageToBraille.save(image, false, "C:/path/to/image.png");
