1. A computer-implemented method for displaying text on a display screen, comprising:
- obtaining the text as a composite bitmap image and a set of word positions associated with words in the composite bitmap image;
dividing the composite bitmap image into a set of individual bitmap images based on the word positions and layout information associated with the text; and
displaying the individual bitmap images on the display screen using the layout information.

Abstract
Some embodiments provide a system for displaying text on a display screen. During operation, the system obtains the text as a composite bitmap image along with a set of word positions associated with words in the composite bitmap image. Next, the system divides the composite bitmap image into a set of individual bitmap images based on the word positions and layout information associated with the text. Finally, the system displays the individual bitmap images on the display screen using the layout information.
