Mask Specification

name

name "<STRING>" ;

This is the name of the mask as shown in the GUI drop-down list.

Mask names should be unique.

units

units "<UNITS>" ;

where UNITS are :

pixels

By default the coordinate system is absolute image pixels,

lower left to top right.

Elements are drawn relative to the lower left corner of a pixel.

normalise

Normalised coordinates map the range 0.0..1.0 to the monitor

source full image pixel size in x and y.

unitsImageAspect

unitsImageAspect <FLOAT> ;

The normalised region may be mapped to an image aspect extraction of the

monitor source full image (pre or post monitor mask).

This is achieved by specifying the target image aspect. Given the monitor

source image and aspect ratio, the normalised region will automatically be

adjusted for 'letterbox' or 'pillarbox' display of the target aspect ratio.

rect

rect <INT x0> <INT y0> <INT x1> <INT y1> ;

Where :

(x0,y0) is rectangle bottom-left.

(x1,y1) is rectangle top-right.

Mask rectangle defined from x0,y0 to x1,y1 using the current coordinate
