Types

type BeginFrameParams 

type BeginFrameParams struct {
	FrameTime  *runtime.Timestamp `json:"frameTime,omitempty"`  // Timestamp of this BeginFrame (milliseconds since epoch). If not set, the current time will be used.
	Deadline   *runtime.Timestamp `json:"deadline,omitempty"`   // Deadline of this BeginFrame (milliseconds since epoch). If not set, the deadline will be calculated from the frameTime and interval.
	Interval   float64            `json:"interval,omitempty"`   // The interval between BeginFrames that is reported to the compositor, in milliseconds. Defaults to a 60 frames/second interval, i.e. about 16.666 milliseconds.
	Screenshot *ScreenshotParams  `json:"screenshot,omitempty"` // If set, a screenshot of the frame will be captured and returned in the response. Otherwise, no screenshot will be captured.
}

BeginFrameParams sends a BeginFrame to the target and returns when the frame was completed. Optionally captures a screenshot from the resulting frame. Requires that the target was created with enabled BeginFrameControl.

func BeginFrame 

func BeginFrame() *BeginFrameParams

BeginFrame sends a BeginFrame to the target and returns when the frame was completed. Optionally captures a screenshot from the resulting frame. Requires that the target was created with enabled BeginFrameControl.

parameters:

func (*BeginFrameParams) Do 

func (p *BeginFrameParams) Do(ctxt context.Context, h cdp.Handler) (hasDamage bool, mainFrameContentUpdated bool, screenshotData []byte, err error)

Do executes HeadlessExperimental.beginFrame against the provided context and target handler.

returns: 

hasDamage - Whether the BeginFrame resulted in damage and, thus, a new frame was committed to the display.
mainFrameContentUpdated - Whether the main frame submitted a new display frame in response to this BeginFrame.
screenshotData - Base64-encoded image data of the screenshot, if one was requested and successfully taken.
