Child Elements:

foregroundMark : A CT_PictureEffectBackgroundRemovalForegroundMark element that specifies a line segment which marks a region to include within a picture.

backgroundMark : A CT_PictureEffectBackgroundRemovalBackgroundMark element that specifies a line segment which marks a region to exclude from a picture.

Attributes:

t : An ST_PositiveFixedPercentage ([ISO/IEC-29500-1] section A.4.1) attribute that specifies the top position of the marquee, relative to the height of a picture.

b : An ST_PositiveFixedPercentage ([ISO/IEC-29500-1] section A.4.1) attribute that specifies the bottom position of the marquee, relative to the height of a picture.

l : An ST_PositiveFixedPercentage ([ISO/IEC-29500-1] section A.4.1) attribute that specifies the left position of the marquee, relative to the width of a picture.

r : An ST_PositiveFixedPercentage ([ISO/IEC-29500-1] section A.4.1) attribute that specifies the right position of the marquee, relative to the width of a picture.
