Canvas meme text generation utilizes the 2D Context typography API (ctx.fillText and ctx.strokeText). Standard internet memes feature bold white Impact typography layered with a thick black stroke outline (ctx.lineWidth = width / 150) and rounded line joins (ctx.lineJoin = 'round') to ensure high contrast legibility across any image background color.
Automatic font sizing calculates proportional typography dimensions relative to base image pixel width ($\text{fontSize} = \text{width} / 12$). Top text is anchored to baseline top (textBaseline = 'top') with a vertical offset margin, while bottom text anchors to baseline bottom (textBaseline = 'bottom').
Because canvas drawing is performed entirely within browser memory, text updates render instantly as users type. Once finalized, the canvas exports to uncompressed PNG blobs via client-side toBlob() calls without third-party server processing.
