Detailed ways

The present invention can obtain a deeper understanding by referring to the specific description of the preferred embodiments in conjunction with the accompanying drawings:

Some typical embodiments embodying the features and advantages of the present invention will be described in detail in the description in the following paragraphs. It should be understood that the present invention can have various changes in different aspects, all of which do not depart from the scope of the present invention, and the descriptions and diagrams therein are used for illustration in nature, not for limiting the present invention. invention.

Please refer to Fig. 2, which is a software architecture diagram of the pagination method of printed files in a preferred embodiment of the present invention, the paging method disclosed in the present invention can be applied to a computer system (not shown) connected with a multifunctional business machine, when using After the user presses the button to print a file that cannot be edited in advance from the computer system, such as a web page, it is necessary to first judge whether there is an icon in the image data of the file, and if the judgment result is yes, store the icon in the file. The location of the area, and the position of the paragraph area of the judgment file contained in the entire file (step S21), and then, the computer system will print the file according to the location of the icon area and the paragraph area of the text. Appropriately print the pages so that the icons are printed on the same page, and the text contained in the file is printed in the most appropriate place according to the position set in the paragraph area (step S22). Finally, the computer system prints each page After the set printing data is coded, it is sent to the multi-function business machine, and the multi-function business machine decodes the coded data received on each page, and then prints out the typesetting document image ( Step S23), using the document images printed by the pagination method of the present invention, the printing range of each page may not be the same, but it can avoid the same icon being cut on two different pages (as shown in Figure 3 ), or the text of the same paragraph can be paged at the most appropriate place.

Please refer to FIG. 4 , which is a flow chart of determining the location of the icon area and the paragraph area of the text contained in the document as shown in FIG. 2 . Among them, judging the location of the icon area and the paragraph area of the text that may be included in the image data of the document, in order to find out the most suitable paragraph basis for pagination in the image data of the document, it can be implemented by the following steps. First, it must be judged Whether the image data of the file is color (step S41), if the file is color, then the image data of the file will be converted into gray scale (step S42), otherwise, if it is gray scale originally, step S41 can be omitted For example, when the image data of the original file is in R, G, and B formats, it can be converted into grayscale values by the following formula, F(x, y)=0.3*R(x, y)+0.59*G( x, y)+0.11*B(x, y), please refer to FIG. 5(a), which is a schematic diagram of the image after converting the color file image data into grayscale. As shown in the figure, the upper right corner of the file 50 has Icon 51, which is an inseparable area position. When the icon 51 is in the image data of the file 50, the user can see the existence of the icon 51 in the file 50, but the computer system cannot know the image data of the file 50 by itself. Contains the icon 51, in this embodiment, after the image data of the file is converted into grayscale, it can be known whether there is an icon in the file 50 through the distribution map of the grayscale in the file 50 (step S43), please refer to the figure 5(b), which is a schematic diagram of the gray scale distribution when the image data of the file does not contain icons. It can be seen from the figure that if the file 50 does not contain any icons, there is only one color dot in the gray scale distribution schematic diagram, that is is the text part, and the other grayscale values have no dots, which means that there is no icon in the file. Please refer to Fig. 5(c), which is a schematic diagram of the grayscale distribution of the file shown in Fig. 5(a). It can be seen from the figure that there are points of any color in the figure, which means that there is an icon 51 in the file 50, and the same There will also be a lot of points in the picture that represent the color of the text.

After judging that there is an icon 51 in the document 50, then, the resolution of the image data of the document 50 can be reduced, so that a plurality of regular dots appear in the text part of the document 50, and a structural analysis can be performed, which can be used for texture analysis. The method is to determine where the icon 51 is in the file 50 (step S44). As for the analysis of the texture of the file 50, entropy or wavelet can be used, but it is not limited thereto. Please refer to Fig. 5(d), which is a schematic diagram of reducing the resolution of the file shown in Fig. 5(a). It can be seen from the figure that by reducing the resolution of the image data of file 50 and analyzing the texture, the Locate the area where the icon 51 in the upper right corner of the file 50 is located.

After determining the position of the area where the icon 51 is located, it is necessary to further judge the position of the paragraph area of the text contained in the file 50, so as to find out the position suitable for pagination in the file 50. Icon 51 part is done binarization operation (as shown in Fig. 5 (e)) (step S45), then, Fig. 5 (e) is carried out vertical projection, by analyzing its projection amount (step S46), find out all For the position suitable for paging, please refer to Figure 5(f), which is a schematic diagram of the projection amount waveform for vertical projection of Figure 5(e). It can be seen from the figure that the position X corresponding to the icon 51 is originally inseparable, so There is no need to filter the projection amount of this interval. As for the boundary between paragraphs and paragraphs between other characters 52 in the file 50, it can be judged by judging the amount of projection, so as to find a suitable position for pagination (step S46).

Because many positions suitable for pagination can be obtained in the file 50 in step S46, the computer system needs to select a most suitable pagination position according to the size of the printing paper, that is, to complete the pagination action (step S47) of finding out the content of a page, and then , deduct the content of the previous page image, analyze the paging content of the next page according to the flow process of steps S41 to S47, until all the image data of the file 50 have been allocated, the effect of paging at the most appropriate position can be reached (step S48 ).

Because there are many ways to print and paginate in the appropriate place of the document, and they are not limited to the above-mentioned embodiment, those who are familiar with the technology can use any method that can judge the position of the icon area and the position of the paragraph area of the text in the image data of the document. Methods are within the protection scope of the present invention.

As mentioned above, the pagination method of the printed document of the present invention, after the computer system issues an instruction to execute the printed document, by judging the position of the area of the icon contained in the document and the position of the paragraph area of the text, the computer system can The area position of the text and the paragraph area position of the text are used to set the print pagination of the document, so that the icons are printed on the same page, and the text of the same paragraph can be paginated at the most appropriate place, so that the user can read it more closely to the typesetting Feel.
