fragments. JPEG is also supported (see Motion JPEG
(MJPEG)).

Types ¶
type Drawer ¶
type Drawer struct {
// contains filtered or unexported fields
}
func (*Drawer) ColorModel ¶
ColorModel implements image.Image.
func (*Drawer) Halt ¶
Halt implements conn.Resource and terminates all running client requests asynchronously.
func (*Drawer) ServeHTTP ¶
func (d *Drawer) ServeHTTP(w http.ResponseWriter, r *http.Request)
ServeHTTP handles HTTP GET requests and sends a stream of images representing the display buffer in response. The display options control the default format and clients can explicitly request PNG or JPEG images using the "format" parameter ("?format=png", "?format=jpeg").
type ImageFormat ¶
type ImageFormat int
const ( PNG ImageFormat = iota JPEG DefaultFormat = PNG )
func ImageFormatFromString ¶
func ImageFormatFromString(value string) (ImageFormat, error)
func (ImageFormat) String ¶
func (f ImageFormat) String() string
type Options ¶
type Options struct {
// Width and height of the image buffer.
Width, Height int
// Format specifies the image format to send to clients.
Format ImageFormat
}
