DOCUMENT PROCESSING USING MULTIPLE PROCESSING THREADS
Systems and methods for assembling parts of a multi-part document. An example method comprises: assigning a plurality of image processing tasks to a plurality of worker processes; defining input parameters for each task of the plurality of tasks, the input parameters comprising a part of an original document and a structure definition of the part, the structure definition including a reference to a element requiring time-consuming processing (e.g., graphical element) comprised by the part of the original document; and outputting, into a file representing the original document, a plurality of images produced by the plurality of worker processes based on elements requiring time-consuming processing (e.g., graphical elements) defined by the input parameters.

outputting, into a file representing the original document, a plurality of images produced by the worker processes based on the elements requiring time-consuming processing defined by the input parameters.
2 . The method of claim 1 , wherein the elements requiring time-consuming processing are graphical elements.
3 . The method of claim 1 , wherein the assigning comprises one of: spawning a new worker process or assigning a task to an existing worker process.
4 . The method of claim 1 , wherein the part of the original document represents a page of a multi-page document.
5 . The method of claim 2 , wherein a worker process of the plurality of worker processes is configured to select a compression algorithm based on a type of the graphical element.
6 . The method of claim 2 , wherein each worker process compresses the graphical element to produce a corresponding image, wherein the corresponding image also includes a change to at least one of, image format, resolution, chromaticity, quality or noise.
7 . The method of claim 1 , wherein each worker process further outputs an image of the part of the original document to be included into the file, the file being compliant to a certain format.
8 . The method of claim 1 , further comprising queuing a new task responsive to determining that a quantity of tasks exceeds a quantity of processing units.
9 . The method of claim 1 , wherein the reference to the element requiring time-consuming processing comprises coordinates of the element requiring time-consuming processing within the original document.
10 . A system comprising:
a memory;
a processor, coupled to the memory, the processor configured to:
assign a plurality of image processing tasks to a plurality of worker processes;
define input parameters for each task of the plurality of tasks, the input parameters comprising a part of an original document and a structure definition of the part, the structure definition including a reference to an element requiring time-consuming processing comprised by the part of the original document; and
output, into a file representing the original document, a plurality of images produced by the worker processes based on the elements requiring time-consuming processing defined by the input parameters.
11 . The system of claim 10 , wherein the elements requiring time-consuming processing are graphical elements.
12 . The system of claim 10 , wherein the assigning comprises one of: spawning a new worker process or assigning a task to an existing worker process.
13 . The system of claim 10 , wherein the part of the original document represents a page of a multi-page document.
14 . The system of claim 11 , wherein a worker process of the plurality of worker processes is configured to select a compression algorithm based on a type of the graphical element.
15 . The system of claim 11 , wherein each worker process compresses the graphical element to produce a corresponding image, wherein the corresponding image also includes a change to at least one of, image format, resolution, chromaticity, quality or noise reduction.
16 . The system of claim 10 , wherein each worker process further outputs an image of the part of the original document to be included into the file, the file being compliant to a certain format.
17 . The system of claim 9 , further comprising queuing a new task responsive to determining that a quantity of tasks exceeds a quantity of processing units.
18 . The system of claim 9 , wherein the reference to the element requiring time-consuming processing comprises coordinates of the element requiring time-consuming processing within the original document.
19 . A computer-readable non-transitory storage medium comprising executable instructions that, when executed by a computing device, cause the computing device to perform operations comprising:
assigning a plurality of image processing tasks to a plurality of worker processes;
defining input parameters for each task of the plurality of tasks, the input parameters comprising a part of an original document and a structure definition of the part, the structure definition including a reference to an element requiring time-consuming processing comprised by the part of the original document; and
outputting, into a file representing the original document, a plurality of images produced by the worker processes based on the elements requiring time-consuming processing defined by the input parameters.
20 . The storage medium of claim 19 , wherein the elements requiring time-consuming processing are graphical elements.
21 . The computer-readable non-transitory storage medium of claim 19 , wherein the assigning comprises one of: spawning a new worker process or assigning a task to an existing worker process.
22 . The computer-readable non-transitory storage medium of claim 19 , wherein the part of the original document represents a page of a multi-page document.
23 . The computer-readable non-transitory storage medium of claim 20 , wherein a worker process of the plurality of worker processes is configured to select a compression algorithm based on a type of the graphical element.
