What is the best method to extract white text written on a blue background in a desktop app?

The method of using the Google OCR engine with the Invert flag can be particularly effective for extracting white text on a blue background. The Invert flag allows the OCR engine to interpret the colors more effectively, converting the image so that the white text becomes black on a new background, making it easier for the software to recognize and extract the text accurately. This is especially useful in scenarios where standard text extraction methods may not perform optimally due to the color contrast challenges presented by the background.

In contrast, using standard text extraction may not work well if the OCR tool is not designed to handle color situations like this, which can lead to recognition errors. Enlarging the text size is helpful in some cases but does not directly address color contrast issues and may not influence text recognition capabilities effectively. Applying color filters could potentially alter the appearance of the text and background but may not provide the accurate recognition needed for text extraction in this specific scenario.
