Example

// Rect
const fill = skPaintNew();
skPaintSetColor(fill, skColorSetArgb(0xFF, 0xFF, 0x00, 0xFF));
const rect = new skRect({
    left: 100,
    top: 100,
    right: 200,
    bottom: 200
});
skCanvasDrawRect(canvas, rect.buffer, fill);

// Text
const familyName = "Times New Roman";
const style = skFontstyleNew(400, 1, enums.UPRIGHT_SK_FONT_STYLE_SLANT);
const typeface = skTypefaceCreateFromNameWithFontStyle(familyName, style);
const text = skPaintNew();
skPaintSetColor(text, skColorSetArgb(0xFF, 0xFF, 0x00, 0x00));
skPaintSetTextsize(text, 50.0);
skPaintSetTypeface(text, typeface);
const str = "skiaJS";
skCanvasDrawText(canvas, str, str.length, 100, 100, text);

// Svg Path
const stroke = skPaintNew();
skPaintSetColor(stroke, skColorSetArgb(0xFF, 0x00, 0x00, 0xFF));
skPaintSetAntialias(stroke, true);
skPaintSetStyle(stroke, enums.STROKE_SK_PAINT_STYLE);
skPaintSetStrokeWidth(stroke, 5.0);
const path = skPathNew();
const svg = "m451.111 451.111h-451.111v-451.111h451.111zm-386.667-64.444h322.222v-322.223h-322.222z";
