TextEnhance

Description

Controls a Canon scanner’s "Advanced Text Enhancement" feature. This function is for highlighting text from its background when contrast is low. For example, red text on pink paper is sometimes difficult to capture by scanner, but this functionality highlights the text by removing the dots around the text.

This can be set only when both TAG_BITSPERSAMPLE and TAG_SAMPLESPERPIXEL are 1 (that is, only when scanning black and white).

For best results, use CanonTextEnhanceBrightness to adjust the brightness.
