Uses Poco clipping too decompress and draw a JPEG image with text superimposed using no extra microcontroller memory needed.

jpeg.js

		let palatino36 = parseBMF(new Resource("palatino_36.fnt"));
		palatino36.bitmap = parseBMP(new Resource("palatino_36.bmp"));

		// background
		poco.begin()
			poco.fillRectangle(gray, 0, 0, poco.width, poco.height);
			poco.drawText("Hello Basuke", palatino36, white, 15, 20);
		poco.end();

		// render JPEG blocks with text composed on top
		let jpeg = new JPEG(new Resource("piano.jpg"));
		let block;
		while (block = jpeg.read()) {
			poco.begin(block.x + 60, block.y, block.width, block.height);
			poco.drawBitmap(block, block.x + 60, block.y);
			poco.drawText("Hello Basuke", palatino36, white, 15, 20);
			poco.end();
		}
