renderShaded

@JvmOverloads
fun renderShaded(cellSize: Int = DEFAULT_CELL_SIZE, margin: Int = DEFAULT_MARGIN, rawData: QRCodeRawData = encode(), qrCodeGraphics: QRCodeGraphics = graphicsFactory.newGraphicsSquare( computeImageSize( cellSize, margin, rawData, ), ), renderer: (Int, Int, QRCodeSquare, QRCodeGraphics) -> Unit): QRCodeGraphics(source)

Renders a QR Code image based on its computed data.

This function provides a way to implement more artistic QRCodes. The renderer is a function that draws a single square of the QRCode. It receives 4 parameters: the (x, y) coordinates where the square is, the cellData and the QRCodeGraphics for it to freely draw.

Tip: for better looking QR Codes, try using QRCode instead ;)

Return

A QRCodeGraphics with the QR Code rendered on it. It can then be saved or manipulated as desired.

Parameters

cellSize

The size in pixels of each square (cell) in the QR Code. Defaults to 25.

margin

Amount of space in pixels to add as a margin around the rendered QR Code. Defaults to 0.

rawData

The data matrix of the QR Code. Defaults to this.encode().

qrCodeGraphics

The QRCodeGraphics where the QRCode will be painted into.

renderer

Lambda that draws a single QRCode square. It receives as parameters the (x, y) of the cell, the QRCodeSquare (aka "cell") being drawn and a QRCodeGraphics for it to draw the square.
