Abstract
A method of combining data sets of heterogeneous image formats, such as PDL's. in a printing system. A first image data set is translated by a coprocessor, using an interpretation code among many stored in memory. In response to "end of job" data in the first image data set, the first image data set in a final image format is transferred to the memory, and a second image data set is transferred from the memory to the coprocessor. The image format of the second image data set is determined. An interpretation code for translating the second image data set is loaded into the coprocessor.
Claims3
In a printing system comprising a coprocessor adapted to translate image data according to an interpretation code, a memory for storing a plurality of interpretation codes and image data, and a guesser for determining an image format of a sample of image data, a method of combining data sets of heterogeneous image formats comprising the steps of:
- translating a first image data set of one image format including "end of job" data;
- in response to translating the "end of job" data in the first image data set, transferring the first image data set in a final image format to the memory, and transferring a second image data set of one image format from the memory to the coprocessor;
- determining the image format of the second image data set;
- loading to the coprocessor an interpretation code for translating the second image data set;
- translating the second image data set including "end of job" data;
- and
- in response to translating the "end of job" data in the second image data set, transferring the second image data set in a final image format to the memory so that the translated second image data set becomes continuous with the translated first image data set in the memory.
