Methods

(static) setOverlayedImage(uri, offsetXPercent, offsetYPercent, widthPercent, heightPercent, callbackopt) → {external:Promise

Sets the image to use as overlay on the detected faces.
Parameters:
Name Type Attributes Description
uri external:String URI where the image is located
offsetXPercent external:Number the offset applied to the image, from the X coordinate of the detected face upper right corner. A positive value indicates right displacement, while a negative value moves the overlaid image to the left. This offset is specified as a percentage of the face width. For example, to cover the detected face with the overlaid image, the parameter has to be 0.0. Values of 1.0 or -1.0 indicate that the image upper right corner will be at the face´s X coord, +- the face´s width.
Note The parameter name is misleading, the value is not a percent but a ratio
offsetYPercent external:Number the offset applied to the image, from the Y coordinate of the detected face upper right corner. A positive value indicates up displacement, while a negative value moves the overlaid image down. This offset is specified as a percentage of the face width. For example, to cover the detected face with the overlaid image, the parameter has to be 0.0. Values of 1.0 or -1.0 indicate that the image upper right corner will be at the face´s Y coord, +- the face´s width.
Note The parameter name is misleading, the value is not a percent but a ratio
widthPercent external:Number proportional width of the overlaid image, relative to the width of the detected face. A value of 1.0 implies that the overlaid image will have the same width as the detected face. Values greater than 1.0 are allowed, while negative values are forbidden.
Note The parameter name is misleading, the value is not a percent but a ratio
heightPercent external:Number proportional height of the overlaid image, relative to the height of the detected face. A value of 1.0 implies that the overlaid image will have the same height as the detected face. Values greater than 1.0 are allowed, while
Note The parameter name is misleading, the value is not a percent but a ratio
