nbgl_drawIcon()

void nbgl_drawIcon	(	nbgl_area_t *	area,
		nbgl_transformation_t	transformation,
		nbgl_color_map_t	color_map,
		const nbgl_icon_details_t *	icon
	)

Helper function to render an icon directly from its nbgl_icon_details_t structure.

The icon is rendered whether it's an image file or not. No transformation is applied to the icon.

Parameters

area	Area of drawing
transformation	Transformation to apply to this icon (only available for raw image, not image file)
color_map	Color map applied to icon
icon	Icon details structure to draw

nbgl_drawQrCode()

void nbgl_drawQrCode	(	const nbgl_area_t *	area,
		nbgl_qrcode_version_t	version,
		const char *	text,
		color_t	foregroundColor
	)

Draws the given text into a V10 QR code (QR code version is fixed using qrcodegen_VERSION_MIN/qrcodegen_VERSION_MAX in qrcodegen.h)

Note

y0 and height must be multiple 4 pixels, and background color is applied to 0's in 1BPP bitmap.

Parameters

area	position, size and color of the QR code to draw
version	version of QR Code
text	text to encode
foregroundColor	color to be applied to the 1's in QR code

		color_t	borderColor
	)

This functions draws a rounded corners rectangle with a border, with the given parameters.

Parameters

area	position, size and background color (outside of the rectangle) to use for the rectangle
radiusIndex	radius size
stroke	thickness of border (fixed to 2)
innerColor	color to use for inside the rectangle
borderColor	color to use for the border
