What method can be used to extract white text written on a blue background in a Citrix environment?

The use of the Microsoft OCR engine's invert property is effective in extracting white text on a blue background in a Citrix environment. Optical Character Recognition (OCR) technology works by recognizing and converting different text formats into machine-readable formats. In scenarios with low contrast between text and background colors, regular OCR techniques may struggle to accurately identify and extract the text. By applying the invert property, the OCR engine processes the colors of the text and background, effectively enhancing the contrast. This enhancement allows the engine to more accurately recognize the white text against the blue background.

The other methods listed are generally less effective for this particular task. Relying solely on the native method may not improve the recognition capabilities for low-contrast text. Full Text extraction methods generally depend on document structures or formats rather than color contrasts and can fail under similar conditions. Adjusting screen contrast settings could help improve visibility for human observers but does not directly improve the OCR capabilities used for automated processes.
