Description

Rasterization processing method, processing device and processing system

technical field

The present invention relates to the technical field of printing processing, in particular to a rasterization processing method, a rasterization processing device and a rasterization processing system.

Background technique

The role of RIP (Raster Image Processor, raster image processor) in the color desktop publishing system is very important. It is related to the quality and speed of the output, and even the operating environment of the entire system. It can be said to be the core of the color desktop publishing system. The main function of RIP is to interpret various images, graphics and text in the computer-made layout into dot matrix information that can be recorded by a printer or an imagesetter, and then control output devices such as a printer, an imagesetter, a computer direct-to-plate machine or a digital printing machine. Image dot matrix information is recorded on paper, film or plate.

RIP is usually divided into hardware RIP and software RIP, and there is also a combination of software and hardware. A hardware RIP is actually a dedicated computer designed to interpret the information on a page. Software RIP calculates pages through software, and transmits the explained record information to the imagesetter through a specific interface card.

At present, the software RIP used for rasterization processing is mainly to generate a rasterized dot matrix from a page description file in PDF (PortableDocument Format) format. The PDF file format has undergone several version changes since its introduction, especially after the PDF1.4 version, its imaging mode was changed to a transparent imaging model. The introduction of transparency greatly enriches the description capabilities of PDF pages. For example, PDF pages can support various special effects such as transparency, shadow, and feathering. However, with the rich page effects described in PDF, especially the extensive use of transparency, the transparent mixed operation of page RIP becomes very complicated and time-consuming, resulting in a very long RIP interpretation time for the entire page, and the overall page interpretation speed becomes very slow .

Therefore, how to effectively improve the processing efficiency of the RIP has become an urgent technical problem to be solved at present.

Fig. 3 shows a schematic block diagram of a rasterization processing system according to an embodiment of the present invention.

As shown in FIG. 3 , the rasterization processing system 300 according to the embodiment of the present invention includes: a scheduling management device 302 connected to at least one print client and configured to receive a print job submitted by the at least one print client The main job management device 304 is connected to the scheduling management device, the main job management device 304 includes: a job request unit 304A, configured to initiate a print job request to the scheduling management device 302, and receive the scheduling management device The print task returned in 302; the job splitting unit 304B is configured to split the to-be-processed document when the number of pages of the to-be-processed document included in the print task is greater than the preset number, and each obtained The number of pages of the split document is less than or equal to the preset number; the main task processing unit 304C is configured to invoke a processing process to process the split document.

Wherein, according to the hardware configuration level of the rasterization processing device (such as the main job management device 304 ), the number of pages of each split document can be set. For example, when the hardware configuration is high, the number of splitting documents to be processed can be increased by reducing the number of pages, thereby calling more processing processes to further improve processing efficiency; when the hardware configuration is low, you can increase the number of splits by increasing The number of pages reduces the number of splits of the document to be processed, thereby reducing the processing load of the rasterization processing device by invoking fewer processing processes.

Of course, the number of splitting documents to be processed is not necessarily equal to the processing process. When there are fewer processing processes, a corresponding task queue can be established for each processing process to process multiple split documents sequentially.

In this technical solution, since the number of pages of the document to be processed is not fixed and may not be divisible by the preset number, the number of pages of the obtained split document may be inconsistent, so that the processing of each processing process cannot be balanced burden. Therefore, by splitting the document to be processed into a single-page document, it is helpful to assign the corresponding split document to each processing process, and to balance the processing tasks between each processing process, so as to make full use of raster Optimize the resources of processing equipment and improve the efficiency of rasterization processing.

Fig. 4 shows a schematic structural diagram of a rasterization processing system according to an embodiment of the present invention.

As shown in FIG. 4 , the rasterization processing system according to an embodiment of the present invention includes: a system configuration and scheduling manager 404 , a master job controller 406 , and a slave job controller 408 .

Wherein, the system configuration and scheduling manager 404 receives the print request submitted by the print client 402, acquires the documents to be processed, and forms a print job.

The main job controller 406 requests a print job from the system configuration and scheduling manager 404, and splits the print job into multiple rasterization tasks, specifically, for example, a single-page rasterization task.

The main job controller 406 is directly configured with a task controller 410A, that is, the task controller 410A and the main job controller 406 can be configured in the same host to make full use of host resources; they can also be configured in different hosts, so that the main The job controller 406 focuses on splitting the print job, while the task controller 410A focuses on the request for the rasterization task, and invokes a specific processing process 412 for processing.

The system can also be configured with a slave job controller 408, and the number of slave job controllers 408 can be one or more, and the master job controller 406 is distributed and run in different hosts to jointly realize the processing of print jobs. Wherein, each slave job controller 408 requests the master job controller 406 to coordinate processing of rasterization tasks.

Each slave job controller 408 is also configured with a corresponding task manager 410B, so as to assign the rasterization tasks acquired by the slave job controller 408 from the master job controller 406 to the corresponding processing process 412 .

Through the split operation of the print job, the cooperative processing at the task level (rasterization task) can be realized between the master job controller 406 and the slave job controller 408; and the master job controller 406 or the slave job controller 408, Parallel processing of tasks can be realized through multiple processing processes 412, thereby helping to improve the processing efficiency of print jobs.

All job controllers form a group (cluster), and a master job controller 406 and one or more slave job controllers 408 may be determined by means of election or the like. Among them, the main job controller 406 is responsible for requesting a job, splitting the job into single-page rasterization tasks, and simultaneously responsible for monitoring and scheduling all single-page rasterization tasks constituting a complete job.

The task controller 410A is responsible for scheduling the rasterization tasks corresponding to the same print job processed by the corresponding processing process 412. After all the rasterization tasks of the same print job are processed, the processing results are combined and fed back to the main job controller 406 .

Similarly, the task controller 410B or the slave job controller 408 is also responsible for scheduling the rasterization tasks corresponding to the same print job processed by the corresponding processing process 412, and when all the rasterization tasks of the same print job are processed, the The processing results are merged and fed back to the main job controller 406 .

The main job controller 406 schedules all rasterization tasks of the same print job, and if all are completed, merges all corresponding processing results to form a processing result corresponding to the print job.

In order to reduce the computational complexity of the system and avoid confusion caused by repeated crossover of rasterization tasks, only the main job controller 406 should request the print job from the system configuration and scheduling manager 404 and perform split task operations, while other The slave job controller 408 only initiates task requests and feedback to the master job controller 406 .

Of course, if the performance of the host computer allows, in fact, the slave job controller 408 can also initiate a request for a print job to the system configuration and scheduling manager 404 . However, when the slave job controller 408 requests a print job, if the job priority being processed by its subordinate master job controller 406 is higher, and the job is set as a coordinated job, then the slave job controller 408 needs to first send the print job to the master The job controller 406 requests a set of page rasterization tasks for the current job to process, or requests a new higher priority print job from the system configuration and scheduling manager 404 to process.

FIG. 5 is a schematic diagram of processing interaction of a rasterization task in the embodiment shown in FIG. 4 .

After the print client (PrintClient) submits and creates a print job ticket (JobTicket) to the system configuration and scheduling manager (SystemCoordinator), the primary job controller (Primary JobController) sends a job request to the system configuration and scheduling manager, and the system configuration and scheduling The manager assigns print job tickets to the master job controller according to the job scheduling algorithm.

After obtaining the print job ticket, the main job controller analyzes the RIP parameters and page file resources, splits the print job ticket into multiple single-page RIP tasks (RipTasks), and adds them to its task queue.

As shown in Figure 5, the main job controller 406 splits the print job ticket and adds it to all task queues, for example, RipTask (Page1) is a single page corresponding to the first page of the print job ticket RIP tasks, other single-page RIP tasks are arranged backwards in sequence.

More specifically, the single-page RIP task queue is a two-dimensional queue, as shown in FIG. 6 . Among them, multiple jobs are arranged vertically and processed sequentially according to the preset order, such as job 1-job 2-...-job N; each job corresponds to multiple single-page RIP tasks, such as job 1 Corresponding to Task 1 - Task 2 - Task 3 and so on.

Wherein, in order to distinguish different jobs and avoid confusion, each print job ticket has a globally unique job identifier. The split single-page RIP task is a smallest RIP processing unit, that is, a page. Each single-page RIP task can enter the single-page RIP task queue in the form of a Key-Value pair. A specific form of a job Key-Value pair is as follows:

<(job id, page number), page data>

Through the job Key-Value pair in the above form, there is an association between each task and the corresponding print job ticket, and different tasks can be effectively distinguished, thereby ensuring the orderly execution of printing tasks.

As shown in Figure 5, the task controller 410A is directly connected to the main job controller 406, and allocates a part of queues from all task queues, such as RipTask (Page1) to RipTask (PageN3); and then, by calling one or more processing Process 412, respectively processes each specific single-page RIP task.

At the same time, for the print tasks that require cooperative processing, the slave job controller 408 initiates a task request to the master job controller 406, and allocates a part of queues from all task queues, such as RipTask (PageN1) to RipTask (PageN2); The task controller 410B distributes the above-mentioned single-page RIP tasks to each called processing process 412, so as to realize the processing of all single-page RIP tasks.

Through the above method, all print job tickets and all single-page RIP tasks obtained by splitting each print job ticket can be processed; then, by processing the results of all single-page RIP tasks corresponding to the same print job ticket Combined processing, the final processing result of the print job ticket can be obtained.

FIG. 7 is a schematic diagram of a specific functional structure of the rasterization processing system of the embodiment shown in FIG. 4 .

As shown in Figure 7, the rasterization processing system includes:

Host A includes a system configuration and scheduling manager 404, a print job queue module 404A, and a shared storage 404B. Of course, the shared storage 404B can also be an independent device, not in the host A; the shared storage 404B provides storage for all the modules in this example.

Host B includes a main job controller 406 , a split module 406A, a task queue 406B, a merge module 406C, a task controller 410A, a task queue 414A, a merge module 416A, and four processing processes 412 . In this embodiment, the above-mentioned modules are all set on a host B, wherein the task queue 406B contains all single-page Rip tasks of a print job, and the tasks in the task queue 414A are a subset of the Rip tasks in the task queue 406B . In this embodiment, it is assumed that the hardware performance of host B can support 4 Rip working processes to work in parallel. The difference between the merging module 406C and 416A is that the merging module 406C merges the task processing results of the entire job. During the entire job processing process, it only submits the result set to the system configuration and scheduling manager 404 on host A once, and the merging module 416A submits the result set every time. 1-4 Rip results (if the 4 processing processes 412 are processing tasks of the same job, they can be combined into one Rip result; if they belong to tasks of different jobs, they can be combined into multiple Rip results; up to 4 tasks The corresponding jobs are all different, that is, 4 Rip results are obtained), which is more frequently submitted than the merge module 406C, and its submission process is limited to the communication within the host B.

Host C includes a slave job controller 408 , a task controller 410B, and four processing processes 412 . In this embodiment, the above modules all reside on the same host C.

In this embodiment, assuming that the print job contains 1000 pages, the slave job controller 408 will cooperate with the master job controller 406 to complete the rasterization of the entire job. The specific implementation steps are as follows:

Step 1, the print client 402 submits a print job to the system configuration and scheduling manager 404 . The system configuration and scheduling manager 404 creates a job ticket JobTicket1, assigns a globally unique JobID and priority, and adds it to the print job queue 404A, and the PDF page files contained in the JobTicket are stored on the shared storage 404B. The JobTicket contains necessary information such as RIP parameters and PDF page resources.

Step 2, when the master job controller 406 is free, it will request a print job from the system configuration and scheduling manager 404, and the system configuration and scheduling manager 404 will assign the job JobTicket1 (assuming it highest priority) is assigned to the main job controller 406.

In this step, the slave job controller 408 can also request the print job from the system configuration and scheduling manager 404. If the master job controller 406 has requested the print job at this time, and the job priority of JobTicket1 is higher, the system configuration And the scheduling manager 404 will direct it to issue a task request to the master job controller 406 . If the master job controller 406 does not need to cooperate, the system configuration and scheduling manager 404 will assign jobs to the slave job controller 408 according to priority, and the job processing steps are the same as those of the master job controller 406; otherwise, if If the task splitting of the job JobTicket1 is not completed, the slave job controller 408 will wait for the next polling, otherwise step 4 is executed, which is the same as the job processing process of the master job controller 406 .

Step 3, after the main job controller 406 obtains the print job ticket, the splitting module 406A splits the JobTicket1 into 1000 PDF single-page RIP tasks, and adds the split tasks to the task queue 406B.

At this time, when the task request from the job controller 408 arrives, the master job controller 406 assigns 4 (or more) single-page RIP tasks to the slave job controller 408 at a time, and the slave job controller 408 will continue to perform subsequent processing The steps are the same as the processing procedure of the master job controller 406 .

In step 4, the task controller 410A executes the control and management of the four processing processes 412 . The task controller 410A regularly polls the main job controller 406. When the task queue 406B of the main job controller 406 is not empty, the main job controller 406 assigns the task to the task controller 410A and changes the task status. In this embodiment Request 4 single-page RIP tasks at a time; if the requested task is empty, wait for the next poll.

Step 5, after obtaining the new single-page RIP task, the task controller 410A queries the currently idle processing process 412, and assigns the single-page RIP task to it when there is an idle processing process 412.

Step 6: After the processing process 412 finishes processing the single-page RIP task, it feeds back the result to the task controller 410A, and the merging module 416A of the task controller 410A merges the task processing results of the same job ID (JobID) according to the task information, and The combined processing results are submitted to the main job controller 406 and a new task is requested from the main job controller 406 .

Step 7: After the main job controller 406 receives the processing results of the single-page RIP task, merge the processing results; if all the single-page RIP tasks of the print job corresponding to the same JobID are all completed, then submit the job to the system configuration and scheduling manager 404 As a result of the processing, the system configuration and scheduling manager 404 checks the job status, and if it is completed, ends the current job processing and returns a successful printing signal to the print client 402, otherwise continues to wait.

If the sub-job controller 409 submits the task processing result at this time, the system configuration and scheduling manager 404 directs the request to the main job controller 406, and the main job controller 406 completes the final result merging and feedback.

Certainly, the processing process of the single-page RIP task by the slave job controller 408 is similar to the processing process controlled by the master job controller 406 . Specifically, the slave job controller 408 requests a single-page RIP task from the master job controller 406 and adds it to the task queue 408A.

Wherein, if the print job is requested from the system configuration and scheduling manager 404 separately from the job controller 408, the page splitting module 408C needs to be used to split the pages, and the obtained single-page RIP task is added to the task queue 408A.

When the job controller 410B initiates a job request, the job controller 408 sends part of the single-page RIP job to the job controller 410B, and adds it to its job queue 414B for further allocation to the processing process 412 .

When the processing process 412 finishes processing the single-page RIP job, it feeds back to the job controller 410B, and the merging module 416B merges the processing results of the jobs belonging to the same print job, and then feeds back to the slave job controller 408 . Similarly, the merging module 408B merges the task processing results belonging to the same print job among the processing results returned by the task controller 410B, so as to finally obtain a complete processing result corresponding to a certain print job.
