Image data processing and image rendering methods and systems whereby images (210b) are displayed on display devices (208) having pixels with separately controllable pixel sub-components (R, G, B). Images, such as text characters (214b), are displayed on a display device (208) with at least some features being rendered with sub-pixel precision. The displayed advance width of a character (214b) displayed with sub-pixel precision is compatible with the advance width of the character (214b) if it had instead been displayed with a conventional full pixel precision rendering process. Thus, characters (214b) are displayed with sub-pixel precision, resulting in improved resolution and readability, while the advance width and the corresponding size and spacing of the characters (214b) and the overall formatting (206a) of the document (210b) remains the same compared to documents and characters rendered using conventional full pixel precision processes. The sub-pixel precision rendering process also involves mapping spatially different sets of one or more samples of the image data to individual pixel sub-components (R, G, B) rather than to full pixels. |
