Code to ASCII Converter

ASCII art text rendering maps each input character to a grid of printable symbols drawn from a fixed-width bitmap font. Misalignment by even one column produces unreadable output. This converter implements five distinct bitmap font families, each storing per-character glyph data as row arrays of width w and height h. Total output width scales as n × w, where n is the character count. Fonts like Banner use h = 6 rows per glyph; Block uses h = 7. The tool handles whitespace preservation, monospace alignment, and graceful fallback for unsupported characters.

Copy-paste of ASCII art into code comments, README files, or terminal banners frequently breaks due to trailing whitespace or tab-vs-space mismatches. This tool outputs clean, space-only text with no trailing whitespace per line. It approximates display-width rendering assuming monospaced terminals. Note: results degrade for proportional-width fonts in rich text editors. For best results, paste output into environments using Courier, Consolas, or similar fixed-width typefaces.

The rendering algorithm processes input text character-by-character. For each character c at position i, the engine retrieves the glyph bitmap G(c) - an array of h strings, each of width w.

Where r is the current row index (0 to h − 1), n is the input string length, G(c) is the glyph lookup function returning an array of h fixed-width strings, and h is the font height in rows. For each row r, the algorithm concatenates the r-th strip from every glyph left-to-right, then appends a newline. The total output has exactly h lines. Characters not found in the font map default to a blank glyph of width w. Lowercase input is auto-converted to uppercase via c ↦ toUpperCase(c) before lookup.
