Property Value

A boolean value which is true for black objects (such as lines) to be enhanced to increase readability. Otherwise, false is returned and no enhancement of black objects is applied.

Remarks

The default value is false.

This property is useful to maintain readability of images when the display size is very small and zoom is applied where dark pixels can be subsampled away.

Note: This property does not modify the image in memory.
