Morse Code Translation Examples

Morse code encoding and decoding, alphabets, separators and application scenarios.

Status

Four documentation examples are implemented: encoding to glyph identifiers, rendering a PNG, decoding to plain text, and a combined scenario. Runtime verification is pending the user-run tests.

Running the examples

From the repository root:

dotnet test src/Aspose.Font.Net/Aspose.Font.Tests.csproj --filter "TestCategory=MorseCodeExamples"

Input under tests-data/Aspose.Font: TTF/LatoWeb-Regular.ttf. Plain-text decoding does not require a font. BaseTests supplies the existing license setup. Output files under tests-out/Aspose.Font.Net/MorseCode: morse.png and callme.png. The PNG fragment continues the font/encoder setup shown in the preceding glyph example; the test supplies that setup outside its snippet.

The current API returns GlyphId[] for glyph encoding and Stream for PNG rendering. Rendering uses pixel line spacing and maximum width; image height is calculated automatically. Character parameters are word separators, not replacement dot/dash symbols. Use IMorseDecoder for plain text; IFontMorseDecoder returns glyph identifiers or a rendered stream.

Example-DecodeMorseToText.cs

// Decode a Morse-code string to plain text
// Learn more: https://docs.aspose.com/font/net/developer-guide/morse-code-translation/

// Plain-text decoding does not require a font.
IMorseDecoder decoder = new TextUtilsFactory().GetMorseDecoder();
string morse = "... --- ...";
string result = decoder.Decode(morse, MorseAlphabets.Latin);
Console.WriteLine(result); // SOS

Example-EncodeMorseToGlyphIds.cs

// Encode text as Morse-code glyph identifiers
// Learn more: https://docs.aspose.com/font/net/developer-guide/morse-code-translation/

// Load a font containing the Morse-code symbols.
string fontPath = Path.Combine(DataDir, "TTF", "LatoWeb-Regular.ttf");
Font font = Font.Open(new FontDefinition(
    FontType.TTF, "ttf", new FileSystemStreamSource(fontPath)));

// Create the factory and get the font encoder.
var factory = new TextUtilsFactory();
IFontMorseEncoder encoder = factory.GetFontMorseEncoder();

// Encode HELLO WORLD using automatic alphabet detection.
GlyphId[] glyphIds = encoder.Encode("HELLO WORLD", font);
Console.WriteLine(string.Join(", ", glyphIds.Select(id => id.ToString())));

Example-MorseCodeEndToEnd.cs

// Render Morse code, obtain glyph identifiers and decode a message
// Learn more: https://docs.aspose.com/font/net/developer-guide/morse-code-translation/

// Load a font.
