Returns a new rectangular viewfinder with default parameters.

color

int getColor()
void setColor(int value)

sizeWithUnitAndAspect

@NonNull SizeWithUnitAndAspect getSizeWithUnitAndAspect()

The size and sizing mode of the viewfinder.

setSize(size)

void setSize(@NonNull SizeWithUnit size)

Added in version 6.0.0

Sets the horizontal and vertical size of the viewfinder to the provided value. When the unit is relative (unit in either x or y is MeasureUnit.FRACTION) the size is computed relative to the view size minus the scan area margins.

setWidthAndAspectRatio(width, heightToWidthAspectRatio)

void setWidthAndAspectRatio(@NonNull FloatWithUnit width,
        float heightToWidthAspectRatio)

Added in version 6.0.0

Sets the width of the viewfinder and compute height automatically based on the provided height/width aspect ratio. When the unit is relative (MeasureUnit.FRACTION), the width is computed relative to the view size minus the scan area margins.

setHeightAndAspectRatio(height, widthToHeightAspectRatio)

void setHeightAndAspectRatio(@NonNull FloatWithUnit height,
        float widthToHeightAspectRatio)

Added in version 6.0.0

Sets the height of the viewfinder and compute width automatically based on the provided width/height aspect ratio. When the unit is relative (MeasureUnit.FRACTION), the height is computed relative to the view size minus the scan area margins.
