[0053] According to a first aspect of the embodiments of the present application, a method for estimating a display level in OFD to HTML conversion is provided. Figure 1 A schematic diagram of a method 100 for estimating a display level in OFD to HTML provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method 100 includes:

[0054] Step S110: When it is determined that the ID information of the target element in the target OFD document is missing, the target display level information corresponding to the target element in the target HTML page is determined according to the relevant information of the target element, wherein the relevant information includes: size information and coordinate information.

[0055] It should be noted that, in some feasible implementations, the target document tree generated by parsing the target OFD document can be traversed, and when it is determined that the ID attribute corresponding to the target element is empty or does not exist according to the target document tree, it is determined that the ID information of the target element in the target OFD document is missing, and the size information and coordinate information corresponding to the target element are determined according to the metadata corresponding to the target element in the target OFD document. The target element can include: text elements, image elements, table elements, and / or graphic elements, etc.

[0056] It should be noted that, when the target element is a graphic element, the size information may include: the length and width of the target element. When the target element is a text element, the size information may include: the length and width of the bounding box corresponding to the target element.

[0057] Exemplarily, the area of ​​the target element can be determined based on the size information. The relative distance between the target elements and / or the drawing order can be determined based on the coordinate information. The target display level information corresponding to the target element can be determined based on the area, the relative distance, and / or the drawing order. It should be noted that the relative distance and / or the drawing order can be used to determine the display order of the target elements and / or the display level of the target elements.

[0058] Step S120: Generate a target HTML page according to the target display level information.

[0059] Exemplarily, according to the above relative distance and / or the above drawing order, all target elements included in each display level can be generated in sequence, and / or corresponding stacking operations can be performed on the target elements included in multiple display levels in sequence, so as to generate a target HTML page accordingly.

[0060] Based on this, the present application provides a method for estimating the display level in OFD to HTML, including: when it is determined that the ID information of the target element in the target OFD document is missing, the target display level information corresponding to the target element in the target HTML page is determined according to the relevant information of the target element, wherein the relevant information includes: size information and coordinate information; and the target HTML page is generated according to the target display level information. The present application can accurately determine the target display level information of the target element in the corresponding target HTML page according to the size information and coordinate information of the target element in the target OFD document when the ID information corresponding to the target element is missing, thereby efficiently and accurately generating the corresponding target HTML page according to the above target display level information, avoiding the inability to determine the corresponding DOM structure according to the target OFD document, resulting in the generated target HTML page having problems such as mutual occlusion of target elements, confusion or error in the display level of the target elements, thereby improving the accuracy of the target HTML page in restoring the target OFD document in the format of the target HTML page.

[0061] In some feasible implementations, the method further includes: determining target display level information according to the ID information when it is determined that the ID information of the target element in the target OFD document is not missing.

[0062] Exemplarily, when traversing the target document tree generated by parsing the target OFD document, if it is determined that the ID attribute corresponding to the target element exists or is not empty according to the target document tree, the target display level information is directly determined according to the ID information.

[0063] Based on this, the above method can determine the target display level information directly based on the ID information when it is determined that the ID information of the target element in the target OFD document is not missing, which is beneficial to improve the generation efficiency of the target HTML page while ensuring the generation accuracy of the target HTML page.

[0064] In some feasible implementations, the above-mentioned determining the target display level information corresponding to the target element in the target HTML page based on the relevant information of the target element includes: determining the relative distance between the first target element and the second target element based on the coordinate information of the first target element and the second target element; determining the areas of the first target element and the second target element based on the size information of the first target element and the second target element; when the relative distance is less than or equal to the preset distance and the area of ​​the first target element is smaller than the area of ​​the second target element, controlling the first target element to be displayed in the first target display level and the second target element to be displayed in the second target display level, wherein the first target display level is stacked on the second target display level.

[0065] Exemplarily, the relative distance may be calculated and determined based on the Euclidean distance or the Manhattan distance according to the coordinate information of the first target element and the second target element. The preset distance may be the minimum preset distance between two adjacent target elements at which there is overlap or intersection. Specifically, the preset distance may be manually set or iteratively determined based on historical generation records.

[0066] Exemplarily, the areas of the first target element and the second target element may be determined according to the following formula:

[0067] (1)

[0068] in, is the area of ​​the target element, is the width of the target element, The height of the target element.

[0069] It should be noted that the above method controls the first target element to be displayed on the first target display level and the second target element to be displayed on the second target display level when it is determined that the above relative distance is less than or equal to the preset distance, that is, the above first target element and the above second target element are overlapped or intersected, and the area of ​​the above first target element is smaller than the area of ​​the above second target element. The first target display level is stacked on the second target display level, which is beneficial to avoid the first target element with a smaller area being obscured by the above second target element with a larger area, resulting in incomplete display content of the target HTML page, thereby helping to improve the display completeness of the target HTML page for the target elements in the target OFD document, and realize the target HTML page to fully reproduce the information contained in the target OFD document.

[0070] In some feasible implementations, the above-mentioned related information further includes: drawing order information; the above-mentioned method further includes: determining target display level information according to the size information, coordinate information and drawing order information.

[0071] Exemplarily, the above-mentioned drawing order information may include: drawing order information of the target element, and / or drawing order information of the target display level, etc.

[0072] Specifically, when it is determined that the drawing order of the first target element is relatively later than the drawing order of the second target element according to the drawing order information of the target elements, the first target display level corresponding to the first target element is controlled to be superimposed on the second target display level corresponding to the second target element.

[0073] Specifically, when it is determined according to the drawing order information of the target display layers that the drawing order of the first target display layer is relatively later than the drawing order of the second target display layer, the first target display layer is controlled to be superimposed on the second target display layer.

[0074] Based on this, the above method can accurately determine the target display hierarchy information according to the above size information, the above coordinate information and the above drawing order information, thereby accurately generating the target HTML page according to the above target display hierarchy information, improving the consistency of the hierarchy overlay order of the above target HTML page, the display order of the target elements and the above target OFD document, and thereby improving the generation accuracy of the target HTML page.

[0075] In some feasible implementations, the above-mentioned determination of the target display level information based on the size information, coordinate information and drawing order information includes: determining the target display level information according to a preset target display level determination function; determining the overlay order information of multiple target display levels according to the target display level information and the first target `z-index` value.

[0076] It should be noted that the above-mentioned first target `z-index` value is the `z-index` value corresponding to the target element.

[0077] Exemplarily, the first target `z-index` value allocation principle can be determined according to the preset variables in the preset hash dictionary, and the first target `z-index` value can be determined according to the first target `z-index` value allocation principle. Specifically, the `z-index` values ​​of the surrounding elements, background elements, and / or intersection elements within the preset distance threshold around the target element can be obtained to determine the first target `z-index` value corresponding to the target element. Among them, the above-mentioned preset distance threshold can be set according to the specific scene requirements.

[0078] Specifically, in determining the first target element , the second target element The third adjacent target element When the corresponding `z-index` value is 93, the first target element is determined , the second target element The corresponding first target `z-index` value should be greater than or equal to 93. The first target element can be determined by superimposing it with 93 as the base. , the second target element The corresponding first target `z-index` value.

[0079] It should be noted that the target Cascading Style Sheets (CSS) can be determined according to the target display level information and the first target `z-index` value to determine the stacking order information of multiple target display levels.

[0080] Based on this, the above method can accurately determine the target display level information according to the preset target display level determination function; accurately determine the overlay order information of multiple target display levels according to the target display level information and the first target `z-index` value, thereby improving the consistency of the display level overlay order of the target HTML page with the target OFD document, and then improving the generation accuracy of the target HTML page.

[0081] In some feasible implementations, the preset target display level determination function includes the following function:

[0082] (2)

[0083] in, is the first display level, is the area of ​​the first target element, is the area of ​​the second target element, is the relative distance between the first target element and the second target element, is the difference between the drawing order of the first target element and the second target element, is the first weight coefficient, β is the second weight coefficient, and γ is the third weight coefficient.

[0084] It should be noted that the first weight coefficient , the second weight coefficient β and the third weight coefficient γ can be automatically set according to specific scenario requirements.

[0085] For example, in If it is greater than 0, the first target element The corresponding first target display level is superimposed on the second target element The corresponding second target displays the level.

[0086] For example, in If it is less than 0, the second target element The corresponding second target display level is superimposed on the first target element The corresponding first target display level.

[0087] For example, in If it is equal to 0, then the first target element With the second target element At the same target level.

[0088] Based on this, the above method can accurately determine the stacking order of the target display levels corresponding to multiple target elements based on the above formula (2), thereby further improving the consistency of the display level stacking order of the target HTML page and the target OFD document, and improving the generation accuracy of the target HTML page.

[0089] In some feasible implementations, the method further includes: determining a second target `z-index` value corresponding to the target display level according to a weight corresponding to each target display level, an index corresponding to the target display level, and a drawing order, when it is determined that the sum of the target display levels corresponding to the target area in the target OFD document is greater than or equal to the sum of the preset display levels, and / or when the sum of the target elements contained in all the target display levels corresponding to the target area is greater than or equal to the sum of the preset target elements; determining, according to the target display level information and the second target `z-index` value, the stacking order information of multiple target display levels corresponding to the target area;

[0090] Among them, the second target `z-index` value corresponding to the target display level is determined according to the following formula:

[0091] (3)

[0092] in, is the second target `z-index` value, is the weight, is the index, The drawing order.

[0093] Exemplarily, the target area may be specified by the target user. Specifically, the target area may be determined by the target user by checking in the target OFD document, and / or by coordinate information manually input by the target user.

[0094] Exemplarily, the above-mentioned preset display level sum value and the above-mentioned preset target element sum value can be determined according to the target user's accuracy requirement for generating a target HTML page based on the target OFD document. Specifically, the above-mentioned preset display level sum value and / or the above-mentioned preset target element sum value are negatively correlated with the target user's accuracy requirement for generating a target HTML page based on the target OFD document, that is, the higher the target user's accuracy requirement for generating a target HTML page based on the target OFD document, the smaller the preset display level sum value and / or the above-mentioned preset target element sum value.

[0095] Exemplarily, the target document tree generated by parsing the target OFD document may be traversed to determine the total number of target elements included in all target display levels corresponding to the target area.

[0096] Exemplarily, based on the target ID information corresponding to the target document tree and / or the above formula (2), different display levels of the sum of all target elements corresponding to the target area can be counted to determine the sum of target display levels corresponding to the target area in the target OFD document.

[0097] Specifically, when it is determined that the sum of the target display levels corresponding to the target area in the target OFD document is greater than or equal to the preset display level sum value, and / or when the sum of the target elements contained in all the target display levels corresponding to the target area is greater than or equal to the preset target element sum value, the superposition order information of multiple target display levels in the target area can be determined based on the above formula (3).

[0098] It should be noted that the above weights Can be used to balance indexes and drawing order The influence of the second target `z-index` value. It is positively correlated with the sum of the target display levels and / or the sum of the target elements contained in all target display levels. That is, the higher the complexity of the target OFD document, the higher the weight. Specifically, the above weight You can set it based on the actual scenario experimental results. For example, you can set the above weights based on the actual scenario requirements. Set to 10 or 100 etc.

[0099] For example, the above index and the above drawing order It can be determined according to the parsing result of the target OFD document. It should be noted that, in some feasible implementations, the above index and the above drawing order It can also be determined by combining the above formula (2).

[0100] Based on this, the above method can be implemented to achieve, when it is determined that the sum of the target display levels corresponding to the target area in the target OFD document is greater than or equal to the sum of the preset display levels, and / or the sum of the target elements contained in all the target display levels corresponding to the target area is greater than or equal to the sum of the preset target elements, based on the above formula (3), according to the weight corresponding to each target display level, the index corresponding to the target display level and the drawing order, accurately determine the second target `z-index` value corresponding to the target display level; according to the target display level information and the second target `z-index` value, accurately determine the superposition order information of multiple target display levels corresponding to the target area, thereby further improving the consistency between the superposition order of each display level of the target HTML page and the superposition order of each display level of the target area of ​​the target OFD document, and improving the layout restoration degree of the target HTML page to the target OFD document.

[0101] In some feasible implementations, the method as described in any of the above items also includes: determining the target transparency of the target element in the target HTML page based on the actual transparency and maximum transparency of the target element in the target OFD document; wherein the target transparency is the ratio of the actual transparency to the maximum transparency.

[0102] Exemplarily, the target transparency can be determined according to the following formula:

[0103] (4)

[0104] in, For the goal transparency, For actual transparency, For maximum transparency.

[0105] It should be noted that the actual transparency of the above target elements in the target OFD document and maximum transparency It can be determined by parsing the above target OFD document.

[0106] Based on this, the above method can accurately determine the target transparency of the target element in the target HTML page according to the actual transparency and maximum transparency of the target element in the target OFD document, thereby improving the determination accuracy of the target transparency corresponding to the target element in the target HTML page, and then improving the transparency reproduction accuracy of the target HTML page for each target element in the target OFD document, and improving the consistency of the transparency information between the target HTML page and the target OFD document.

[0107] In some feasible implementations, the above method also includes: when the target element is a vector graphic, generating a preset type element corresponding to the target element according to the target element; generating a target HTML page according to the preset type element, wherein the preset type element includes: SVG type element, and / or Canvas type element.

[0108] Exemplarily, when the target element is determined to be a vector graphic by parsing the target OFD document, a corresponding SVG element and / or Canvas element is generated based on the target element; and a target HTML page is generated according to the SVG element and / or Canvas element corresponding to the target element.

[0109] Based on this, the above method improves the cross-platform compatibility of the target HTML page and the display quality and clarity of the target elements of the target HTML page while ensuring that the target HTML can fully reproduce the content of the target OFD document, which is conducive to providing convenience for the target user to modify or edit the target HTML page, and is conducive to reducing the loading time of the target HTML page and improving the display efficiency of the target HTML page.
