¶
A dead simple go library for interacting with the linux framebuffer (implements image/draw.Image). Probably not ready for anything production-y; was just a late night diversion.
Documentation

Overview ¶
An image/draw compatible interface to the linux framebuffer
Use Open() to get a framebuffer object, draw on it using the facilities of image/draw, and call its Flush() method to sync changes to the display.

Types ¶
type FrameBuffer ¶
type FrameBuffer struct {
// contains filtered or unexported fields
}
A framebuffer object. Obtain with Open() - the zero value is not useful. call Close() when finished to close the underlying file descriptor.
func Open ¶
func Open(filename string) (*FrameBuffer, error)
Opens/initializes the framebuffer with device node located at <filename>.
func (*FrameBuffer) Bounds ¶
func (fb *FrameBuffer) Bounds() image.Rectangle
func (*FrameBuffer) ColorModel ¶
func (fb *FrameBuffer) ColorModel() color.Model
func (*FrameBuffer) Flush ¶
func (fb *FrameBuffer) Flush() error
Sync changes to video memory - nothing will actually appear on the screen until this is called.
func (*FrameBuffer) WritePixel ¶
func (fb *FrameBuffer) WritePixel(x, y int, r, g, b uint8)
