Data recovery method |
摘要 |
<p>A data recovery method compris es the step of expanding first data into second data, the first data including information of characters and information of a predetermined special effect related to the characters, the second data having segments each corresponding to a pixel, wherein every 1-pixel-corresponding segment of the second data is of a predetermined code having a set of different code words, wherein every 1-pixel-corresponding segment of the second data is changeable among the different code words, wherein a predetermined one of the different code words is assigned to a 1-pixel-corresponding piece of the information of the special effect which represents that a corresponding pixel should be a portion corresponding to the special effect while others of the different code words are assigned to every 1-pixel-corresponding piece of the information of the characters and a 1-pixel-corresponding piece of the information of the special effect which represents that a corresponding pixel should not be a portion corresponding to the special effect; and detecting whether or not a state of every 1-pixel-corresponding segment of the second data agrees with the predetermined one of the different code words to decide whether or not a corresponding pixel should be a portion corresponding to the special effect. <IMAGE></p> |
