# EffectSpotLight

EffectSpotLight function illuminates a specified circular disc area. The illumination color can be specified and remains constant. The spot center moves from the initial center coordinates in pixels to the final coordinates. Dim controls the factor by which the scene is dimmed prior. RGB32, RGB24 and YV12 formats only are supported.

Details of parameters
Description | Name | Type | Limits | Default
clip |  | clip |  | none
Effect start frame number | sf | Integer | within clip | first frame
Effect end frame number | ef | Integer | within clip | last frame
radius of illuminated disc | radius | integer | 8 to 1/2 of frame lesser dimension | 40
illuminating color | lumen | integer | bbggrr format | 0x5f5f5f
initial x coordinate of the sparkler | initx | integer | within frame | radius
initial y coordinate of the sparkler | inity | integer | within frame | radius
final x coordinate of the sparkler | finalx | integer | within frame | initx
final y coordinate of the sparkler | finaly | integer | within frame | inity
dimming factor | dim | integer | 1 to 16 | 4

#Usage examples:-

    EffectSpotLight(sf=51,ef=158,lumen=$7f007f, initx=40,inity=240,finalx=700,finaly=400, dim=6)
    For stationary spot position, no prior dimming
    EffectSpotLight(dim=1)
    #All defaults spot remains stationary at left corner
    EffectSpotLight()
