  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram illustrating an example of a hardware configuration of the information processing apparatus.
The information processing apparatus 101 performs processing by inputting and editing data from a pointing device such as a keyboard 122 and a mouse 123 via the I / O interface 115.
The information processing apparatus 101 typically includes at least one processor unit (CPU) 111 and a memory unit 116 including a semiconductor random access memory (RAM) and a read only memory (ROM).
The display device 121 is connected to the video interface 114 and outputs to the screen.
The network interface 112 can connect the information processing apparatus 101 to a network and connect to another computer apparatus of the system. A typical network connection is a local area network (LAN) or a wide area network (WAN).
The information processing apparatus 101 also includes a storage device 113 such as a hard disk or an SSD, in which an operation system program is stored.
The CPU 111 executes processing based on a program stored in the storage device 113 or the like, thereby realizing the functions of the information processing device and the processing of a flowchart described later. The input means is not limited to the keyboard 122 and the mouse 123, and may be a touch panel integrated with the display means.

As long as the functions of the following embodiments are executed unless otherwise specified, a single device or a system composed of a plurality of devices may be used. Alternatively, the software to be executed may be a printer driver incorporated in a computer system or an operating system operating on a printing apparatus such as a printer.
In this specification, as an example of an electronic book, ePub, which is a file format for an electronic book promoted by IDPF (International Electronic Publishing Forum), will be described. At this time, the file format is not particularly limited as long as the file format conforms to the Open Container Format (OCF) or has an equivalent structure.
Also, when acquiring and setting a style sheet value, unless otherwise specified, in principle, it refers to an operation on a style sheet class or ID corresponding to a specified content tag.
Before describing the embodiment described below, a description will be given of the direction in which characters flow. The direction of the flow of characters indicates whether the characters move from left to right or right to left on the page. The flow from left to right is from right to left, and right from left to right. It describes as follows. More specifically, when a character is poured into a blank page, a determination is made as to where the start position and end position of the character are on the left and right. For example, in horizontal Japanese, the start point is at the upper left and the end point is at the lower right, so it is classified as a document that flows to the right.

<Embodiment 1>
Here, an outline of the process for explaining the data conversion process of the present embodiment will be described with reference to FIG. FIG. 2 is a diagram for explaining the outline of the processing.
First, the page 301 is a horizontally written document that flows to the right. When the text portion 304 of this page 301 is converted to vertical writing, it becomes a page 302, which becomes a document that flows to the left. In the present embodiment, first, the direction in which characters flow is switched as described above.
In addition, in the present embodiment, the arrangement direction of the drawings is switched. In the previous example, characters flowed from the left to the right on the page 301, and the order of 306 and 307 was also good in the figure. However, on page 302, the flow of characters changes from right to left, so the second corresponding 308 comes out first. For this reason, in the present embodiment, conversion is performed so that the arrangement of the figures is also arranged in the reverse direction of 310 and 309 as in the page 303 in accordance with the flowing direction of the characters.
A figure or table is an example of an object in a page.

FIG. 3 is a flowchart illustrating an example of information processing related to data conversion.
In the description, first, the correspondence relationship between the page 301 and the HTML 316 displayed in FIG. 2 will be described. The portion corresponding to the content portion of the page 301 is HTML 316, the text content is composed of the div tag 312, and the image content is composed of the div tag 313. Here, the div tag 312 corresponds to the text portion 304 of the page 301. The div tag 313 corresponds to the image unit 305. Note that the image unit 305 is arranged at the bottom of the page according to the definition of “display: oeb-page-foot” in the div tag 313. The definition here is only given as an example, and it is the same even if it is placed at the bottom of the page using any position designation method including absolute position designation such as “position: absolute, bottom: 0 px”. Meaningful.

In step S201, the CPU 111 acquires setting information (setting value) based on, for example, a user operation. The setting information here refers to data necessary for ePub data conversion, and includes setting information for changing the direction in which characters flow. More specifically, the switching between the vertical writing and the horizontal writing, the switching of the display language, etc. corresponds to the setting information for changing the direction in which the characters flow.
In step S202, the CPU 111 performs processing for opening an ePub document to be converted. This process means that an ePub document is loaded into the memory unit 116, and both an XML file or HTML file as a main body and a CSS file as a setting can be referred to and edited. If necessary, the CPU 111 may perform processing such as copying to the storage device 113 as a temporary file or decompressing the Zip.
In step S203, the CPU 111 sets the direction in which characters flow. In this process, the CPU 111 obtains the results from page 301 to page 302. Details of this processing will be described with reference to FIG.

In step S <b> 204, the CPU 111 reads out information of a figure and a table from an HTML file that is a text. Here, the number of read units is not limited to one as long as they are continuously arranged or defined as a group of groups such as the div tag 313 in FIG.
In step S205, the CPU 111 detects the arrangement of the figures. The CPU 111 detects in which direction the figure is arranged with respect to the page in the same manner as the direction in which characters flow. In the example of the page 301 in FIG. 2, the image in the div tag 313 corresponding to the image part 305 specifies the definition 318 of the CSS 317. In the definition 318, “float: left” is specified, and the contents are arranged left-justified, so the CPU 111 detects that the image unit 305 is aligned from left to right.
In step S206, the CPU 111 determines whether or not the character flow direction set in step S203 matches the figure sequence detected in step S205. If they match, the CPU 111 proceeds directly to step S208, which is the next process. If they do not match, the CPU 111 proceeds to step S207 to change the arrangement of the figures.

In step S207, the CPU 111 changes the arrangement order of the drawings. When the image unit 305 in FIG. 2 is changed, the CPU 111 detects the CSS definition 318 corresponding to the class in the corresponding div tag 313 and rewrites the internal definition. In the example of FIG. 2, the CPU 111 rewrites “float: left” to “float: right”.
In addition, the designation of the filling direction such as “float: left” in FIG. 2 is not used, and two tables are allocated in a transparent 1-by-2 table, for example, using the table tag, and arranged side by side. May have been. When such a CSS definition cannot be used, the CPU 111 replaces the arrangement of the figures by rewriting the HTML 316. The CPU 111 rewrites the HTML file so that the image tags 315 and 314 are in this order in the HTML 316. In this conversion processing example, only left and right replacement is performed, but when horizontal writing and vertical writing are switched, the CPU 111 may perform processing for replacing the arrangement of the figures by 90 degrees. For example, in horizontal writing, the charts are arranged in the order of left and right, but when changed to vertical writing, the CPU 111 converts them 90 degrees to the right and arranges them in the order of top and bottom. In accordance with this conversion, the CPU 111 may change the “up, right, down, left” designated as “up, right, down, left” to “right, down, left, up”.
In step S208, the CPU 111 determines whether or not a figure or table remains in the text, and if it remains, the process proceeds to the figure acquisition process (step S204) again, and no figure or table remains. In the case, the process shown in FIG.
By performing the above processing, the CPU 111 converts the ePub document.

FIG. 4 is a flowchart illustrating an example of information processing for setting a direction in which characters flow.
In step S401, the CPU 111 determines whether or not language switching is set. If it is necessary to switch, the process proceeds to step S402. If it is not necessary to switch, the process proceeds to step S403. Note that this determination is made based on the value set in step S201 in the flowchart of FIG.
In step S402, the CPU 111 replaces text in the document. When the replacement is performed, the CPU 111 performs replacement with the text HTML of another language prepared in advance. On the other hand, when a plurality of languages are incorporated in one HTML file, the CPU 111 changes the definition of the language switching unit. In addition, when the HTML file is directly rewritten using a translation engine, the CPU 111 extracts the text, applies it to the translation engine, and replaces the result with the text.

In step S403, the CPU 111 determines whether to switch between vertical writing and horizontal writing. Similarly to step S401, the CPU 111 performs this based on the value set in step S201 of the flowchart of FIG. If the CPU 111 determines that switching between vertical writing and horizontal writing is to be performed, the process proceeds to step S404, and if it is determined that switching is not to be performed, the processing illustrated in FIG.
In step S404, the CPU 111 analyzes the text. In the example of HTML 316, the CPU 111 reads the text and analyzes the correspondence between the content and the definition of the CSS 317 associated with the content. The CPU 111 clarifies the CSS definition part to be replaced in the next step and analyzes whether there is a body part that is not a replacement target. The part of the text that is not subject to replacement here is a part that is different from the original text in the first place, that is, a vertically written part in the horizontally written text or a part that is originally different in language.

In step S405, the CPU 111 rewrites the CSS definition based on the analysis result in step S404. In the example of FIG. 2, when simply rewriting the entire document, the CPU 111 may apply the CSS definition 319 to the body tag 311. More specifically, the CPU 111 designates “<body>” of the body tag 311 as “<body class =“ “textArea”> ””. At this time, the CPU 111 may use a description of “<body style =“ ”writing-mode: vertical-rl”> ”that directly specifies the style. Further, the CPU 111 may rewrite the tags indicating the text part of all body parts including the div tag 312 indicating the text part of the body without specifying the body tag 311 whose application range is the whole body.
By performing the above processing, the direction in which characters flow is set.

<Embodiment 2>
In the first embodiment, the arrangement of the figures is changed in accordance with the direction in which the characters flow. However, in some cases, it may be difficult to read by simply changing the arrangement. These will be described with reference to FIGS.
In FIG. 5, when the images 601 and 602 are simply replaced, a result like a result 603 is obtained. When the diagrams arranged in this way are combined like a figure, or when there is a correspondence between the left and right, for example, the right diagram has an arrow pointing to the left diagram, the positions are rearranged. Simply doing so can cause inconvenience.
Moreover, FIG. 6 is a figure which shows an example which has displayed the character superimposed on the figure. In particular, since the image 701 has a polygonal character area such as the area 702 set on the drawing, the characters are also laid out so as to fit within the area 702. At this time, if the character is changed to vertical writing, the beginning of the sentence is just a line feed as seen in the image 703, making it difficult to read.

FIG. 7 is a flowchart showing an example of information processing for performing inversion of the figure and inversion of the area when a character area is set on the figure in order to cope with the above problem. The process of this flowchart is performed, for example, before step S208 in FIG.
In step S501, the CPU 111 determines whether it is necessary to reverse the drawing. The CPU 111 makes a determination based on whether or not the text flow direction of the document has been switched. However, since some other settings may be partially made, the CPU 111 is limited to the chapter, page, or region where the figure is placed. A determination may be made. If the CPU 111 determines that the inversion of the figure is necessary, the process proceeds to step S502. If the CPU 111 determines that the inversion of the figure is not necessary, the process proceeds to step S503.
In step S502, the CPU 111 inverts the figure. The CPU 111 performs left-right inversion (with respect to the X axis) by defining “transform: scaleX (−1)” for the image. When the left and right are overlapped as shown in FIG. 5, the CPU 111 also reverses the overlap designation portion. For example, the image 602 is specified to overlap a part of the left side with the image 601. In this case, when overlapping the left side image by 40 pixels, a negative margin of 40 pixels is set on the left side like “margin-left: −40 px”. Is set. In the case of inverting the image 604, the CPU 111 performs setting so that the left margin and the right margin are interchanged. More specifically, the CPU 111 rewrites “margin-left: −40 px” to “margin-right: −40 px”.

In step S503, the CPU 111 determines whether a character is arranged on the image. If a character is placed on the image, the CPU 111 proceeds to step S504, and if not, the process shown in FIG.
In step S504, the CPU 111 inverts the character area on the image. Taking the area 702 as an example, here, an area is designated like an image 705. The notation of HTML and CSS at this time is shown in FIG. 8, and the HTML portion is an image definition 801 and a character definition 802 to be arranged on the image. On the CSS, a definition 803 for designating the shape of the character definition 802 is provided, which corresponds to the vertex coordinates of the area 706 in the image 705. In this step, the CPU 111 rewrites the definition 803 so that the definition of the region becomes the region 708 as the image is inverted. Here, the definition of “shape-inside: polygon (10 px 10 px, 150 px 10 px, 100 px 50 px, 10 px 60 px)” is taken as an example. The CPU 111 rewrites this as “shape-inside: polygon (50px 10px, 190px 10px, 100px 50px, 190px 60px);” to realize the processing of this step.
By performing the above processing, the image and the character area are inverted.
