Animator Contour

See the source code: FITS | CASA | HDF5

Measures animation playback performance with contour overlays, testing both forward and backward channel animation. The elapsed time is measured between the START_ANIMATION request and the STOP_ANIMATION request while playing the animation forwardly.

  1. Frontend sends: OPEN_FILE (OpenFile)

    directory = "set_QA_performance"
file = "cube_B_06400_z00100.<fits|image|hdf5>"
file_id = 0

  2. Frontend loads initial tiles and sets contour parameters

    levels = [-0.01, 0.01]
smoothing_mode = GaussianBlur
smoothing_factor = 4
decimation_factor = 4

Case 1: Forward animation (channels 1 to 30)

  1. Frontend sends: START_ANIMATION (StartAnimation)

    start_frame = {channel: 1, stokes: 0}
first_frame = {channel: 0, stokes: 0}
last_frame = {channel: 44, stokes: 0}
delta_frame = {channel: 1, stokes: 0}
frame_rate = 5

  2. Animation plays with ANIMATION_FLOW_CONTROL per frame, stops at channel 30

Check 1: within the playAnimator timeout (300,000 ms):

  • START_ANIMATION_ACK.success = True

  • RASTER_TILE_DATA channels are in ascending order

  • CONTOUR_IMAGE_DATA channels are in ascending order (2 levels per channel)

  • REGION_HISTOGRAM_DATA channels are in ascending order

Case 2: Backward animation (channels 40 to 31)

  1. Frontend sends: START_ANIMATION with delta_frame = {channel: -1}

Check 2: within the playAnimator timeout (300,000 ms):

  • RASTER_TILE_DATA channels are in descending order

  • CONTOUR_IMAGE_DATA channels are in descending order

  • REGION_HISTOGRAM_DATA channels are in descending order
