This function is called once for each area of inverted text that is detected. Return SUCCESS_REMOVE to have the area modified. Return SUCCESS_NOREMOVE to leave the area unchanged. Pass any other value to abort. This value will be the return value of the LBitmap::InvertedText(). If flags INVERTEDTEXT_IMAGE_UNCHANGED and INVERTEDTEXT _SINGLE_REGION are being used, then the return value of this function affects only the internal single region that contains all the changes.
