Abstract
A graphic processing method is implemented to determine which processing method is to be performed to improve graphic processing speed. First, it is determined whether the document page to be processed includes a large amount of graphics, in which case the document page is divided into a plurality of blocks to be sampled. First and second processing methods are then applied to the block samples to determine which processing method requires less time. The graphic processing method of shorter time duration is then implemented to process the whole document page.
Claims3
A graphic processing method comprising:
- determining whether graphic processing commands with respect to graphics of a document page are greater than processing commands with respect to texts and images of the document page;
- dividing the document page into a plurality of blocks, and storing the blocks;
- sampling the blocks to form a plurality of block samples, and storing the block samples;
- respectively applying a first processing method and a second processing method on the block samples to obtain a first processing time and a second processing time, wherein the first processing method includes converting color portions of a graphics from RGB color mode to CMYK color mode and performing dot layout of the color portions, while the second processing method includes converting color portions of a graphics from RGB color mode to CMYK color mode and performing dot layout of the color portions together with the shape of the graphics;
- determining whether the first or second processing time is shorter, and selecting the corresponding processing method;
- and
- implementing the selected processing method to process the document page.
