Text Rendering

Text renderer draws text to canvas with font support.

Rendering Text

Create TextRenderer and draw text at position.

enjin2::TextRenderer<uint8_t> text;
text.setCursor(10, 10);
text.drawString(canvas, 10, 10, "Hello World");

setTextColor(color) - Set text color (transparent background).

text.setTextColor(15); // White text

setTextColor(color, bg) - Set text color with background.

text.setTextColor(15, 0); // White on black

setTextSize(size) - Set text scaling (1 = normal, 2 = double).

text.setTextSize(2); // Double size

setTextSize(sx, sy) - Set separate X/Y scaling.

text.setTextSize(2, 1); // Double width, normal height

setCursor(x, y) - Set text position.

text.setCursor(20, 30);

Default 5x7 font is built-in.

Use custom fonts with GFX font format.

extern const GFXfont customFont;
text.setFont(&customFont);

getTextWidth(str) - Measure text width.

uint16_t width = text.getTextWidth("Hello");

getTextBounds(str, x, y, x1, y1, w, h) - Get bounding rectangle.

int16_t x1, y1;
uint16_t w, h;
text.getTextBounds("Hello", 10, 10, &x1, &y1, &w, &h);

Text position is cursor-based: set cursor once, draw multiple strings.

text.setCursor(10, 10);
text.writeString(canvas, "Line 1\n"); // Cursor advances
text.writeString(canvas, "Line 2\n");

Cache frequently used strings in const char* arrays.

Use monospaced fonts for predictable layout.

Avoid frequent setFont() and setTextSize() calls.
