[0001] This application relates to the field of document processing technology, and more specifically, to a method, apparatus, device, and storage medium for replacing logo images within a document. Background Technology

[0002] In the process of modern enterprise digital operations, daily business operations generate a massive amount of electronic documents in heterogeneous formats, such as Word and Excel. These business documents not only carry the company's core business information but also serve as important windows for showcasing the company's brand image. With strategic adjustments and brand upgrades, the company logo, as the core visual identifier of the brand image, frequently needs to be changed and iterated. In practical applications, differences in logo versions within business documents can lead to inconsistencies in brand image expression, affecting the professionalism and standardization of the company's external presentation.

[0003] Currently, updating logos in business documents of different formats generally involves manual editing and replacement of each document. This method has significant technical bottlenecks: on the one hand, manual operation consumes a large amount of time and manpower when dealing with tens of thousands of documents; on the other hand, due to the diverse document formats and complex content, manual operation is prone to omissions and errors, and it is difficult to guarantee the consistency of the replacement effect.

[0061] In the process of modern enterprise digital operations, daily business operations generate a massive amount of electronic documents in heterogeneous formats, such as Word and Excel. These business documents not only carry the company's core business information but also serve as important windows for showcasing the company's brand image. With strategic adjustments and brand upgrades, the company logo, as the core visual identifier of the brand image, frequently needs to be changed and iterated. In practical applications, differences in logo versions within business documents can lead to inconsistencies in brand image expression, affecting the professionalism and standardization of the company's external presentation.

[0062] Currently, updating logos in business documents of different formats generally involves manual editing and replacement of each document. This method has significant technical bottlenecks: on the one hand, manual operation consumes a large amount of time and manpower when dealing with tens of thousands of documents; on the other hand, due to the diverse document formats and complex content, manual operation is prone to omissions and errors, and it is difficult to guarantee the consistency of the replacement effect. Therefore, improving the accuracy and efficiency of logo updates is an urgent problem to be solved.

[0063] Based on the above research, this disclosure provides a method for replacing logo images within a document. The method acquires an original document and a target logo image, and detects the document format type of the original document. Next, based on the document format type, a parsing algorithm corresponding to the document format type is used to parse the original document, obtaining attribute information for the placement unit corresponding to each original logo image. The placement unit is used to hold the logo image, and the attribute information includes size information. Then, for any original logo image, the size of the target logo image is adjusted according to the size information of the placement unit corresponding to the original logo image, so that the target logo image matches the size of the placement unit corresponding to the original logo image. Finally, the original logo image is replaced based on the size-adjusted target logo image to obtain the target document.

[0064] In this embodiment, since the placement unit is used to carry the logo image, for any original logo image, the size of the target logo image is adjusted according to the size of its corresponding placement unit, so that the target logo image is adapted to the size of the placement unit. In this way, the original logo image is replaced based on the size-adjusted target logo image to obtain the target document. Thus, automated logo image replacement can be achieved, which helps to reduce labor costs and improve replacement efficiency.

[0065] To facilitate understanding of this embodiment, a detailed description of the method for replacing logo images within a document disclosed in this disclosure embodiment will be provided first. The executing entity of the document logo image replacement method provided in this disclosure embodiment is generally an electronic device. The electronic device can be a server, which can be an independent physical server, a server cluster composed of multiple physical servers, or a distributed system. It can also be a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud storage, big data, and artificial intelligence platforms. In other embodiments, the electronic device can also be a terminal device, wherein the terminal device can be a mobile device, terminal, handheld device, computing device, vehicle-mounted device, etc.

[0066] In other embodiments, the method can also be applied to an implementation environment consisting of electronic devices and servers. Furthermore, the logo image replacement method within the document can also be implemented by a processor calling computer-readable instructions stored in memory.

[0067] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0068] Please participate in the attached... Figure 1 The above is a flowchart illustrating a method for replacing a logo image within a document, as shown in an exemplary embodiment of this application. Figure 1 As shown, the method for replacing the logo image within a document in this embodiment may include the following steps S101~S104:

[0069] S101: Obtain the original document and the target logo image, and detect the document format type of the original document.

[0070] The number of original documents can be one or more, and is not limited here. The original documents can be Word documents or Excel documents, and include the original logo image. Typically, each page of the original document includes the original logo image. Of course, in other embodiments, only some pages of the original document may include the original logo image.

[0071] In some implementations, the target logo image may be an updated version of the original logo image; in other implementations, the target logo image may be an image unrelated to the content of the original logo image, and this is not limited thereto.

[0072] It is understandable that after obtaining the original document, the document format type can be identified through the document format parsing algorithm, that is, the document format type (Word document or Excel document) of the original document can be detected.

[0073] S102: Based on the document format type of the original document, the original document is parsed using a parsing algorithm corresponding to the document format type to obtain the attribute information of the placement unit corresponding to each original logo image; the placement unit is used to carry the logo image, and the attribute information includes size information.

[0074] In this embodiment of the application, different document format types correspond to different parsing algorithms. Specifically, Word documents correspond to the Word document parsing algorithm, and Excel documents correspond to the Excel document parsing algorithm.

[0075] In this way, by parsing the original document using a parsing algorithm corresponding to the document format type, the attribute information of the placement unit corresponding to each original logo image can be obtained. The placement unit is used to carry the logo image, and the placement unit is different in the original document of different document format types.

[0076] The attribute information of the placement unit includes size information, specifically height and width information. In other embodiments, it may also include color information, position information, etc., which are not limited here.

[0077] It's important to note that containers don't exist explicitly in a document; rather, they are the underlying structure obtained from parsing the document. Each container can include one or more elements, such as image elements and text elements.

[0078] As mentioned above, the original document may include one or more original logo images. Therefore, after parsing, the attribute information of the placement unit corresponding to each original logo image can be obtained, that is, the size information of the placement unit corresponding to each original logo image can be obtained.

[0079] S103: For any original logo image, adjust the size of the target logo image according to the size information of the placement unit corresponding to the original logo image, so that the size of the target logo image is adapted to the size of the placement unit corresponding to the original logo image.

[0080] After obtaining the size information of the placement unit corresponding to each original logo image, the size of the target logo image can be adjusted according to the size information of the placement unit corresponding to the original logo image. Here, the size of the target logo image can be adjusted to the size of the placement unit corresponding to the original logo image, so that the size of the target logo image can be adapted to the size of the placement unit corresponding to the original logo image.

[0081] It should be noted that if the size information of the placement unit corresponding to different original logo images is different, then the target logo image needs to be resized multiple times.

[0082] S104: Replace the original logo image with the resized target logo image to obtain the target document.

[0083] Since the size of the target logo image after size adjustment is compatible with the size of the placement unit corresponding to the original logo image, the original logo image can be replaced based on the target logo image after size adjustment. In this way, each original logo image in the original document can be replaced with a target logo image of the same size, thus obtaining the target document.

[0084] The above method can automatically replace the original logo image. Compared with the "manual editing and replacement" method in related technical solutions, it can reduce labor costs, improve replacement efficiency and accuracy, and make the size of the target logo image match the size of the corresponding original logo image placement unit, thus improving the aesthetics of the logo in the document.

[0085] In some implementations, for step S102, if the document format type includes a Word document, the Word document parsing interface is called to parse the original document and obtain the size information of the placement unit corresponding to each original logo image.

[0086] In Word documents, the placement unit is an image container.

[0087] The following is a detailed explanation of the logo replacement process in Word documents.

[0088] When the Word document parsing interface is called to parse the original document and obtain the size information of the placement unit corresponding to each original logo image, the size information of at least one container corresponding to each header in the original document can be obtained by calling the Word document parsing interface to parse the original document, and the size information of the logo container corresponding to each original logo image can be determined from the size information corresponding to multiple containers respectively.

[0089] It is understandable that in a Word document, the logo image is usually located in the header. Therefore, by parsing the original document to obtain the XML document, we can further traverse the header of each page in the XML document to obtain the size information of at least one container corresponding to each header. Here, the header may contain multiple containers, and the multiple containers may be different from each other.

[0090] Thus, after obtaining the size information of at least one container corresponding to each header, the size information of the logo container corresponding to each original logo image can be determined from the size information of the multiple containers respectively.

[0091] This step can be understood as selecting a logo container from multiple containers. Since the logo container is used to hold the logo image, for each container, it can be determined whether the resource attribute information of the container includes an image element. If it includes an image element, the container is considered a logo container. After the determination, the size information of the container corresponding to the resource attribute information that includes the image element can be determined as the size information of the logo container corresponding to the original logo image.

[0092] For example, the xPath resource attribute information of each container in the XML document can be parsed. If the xPath resource attribute information contains the "drawing" element, it is determined that the container contains an image element.

[0093] Furthermore, after determining the size information of the logo container corresponding to the original logo image, for any original logo image, the size of the target logo image can be adjusted according to the size information of the logo container corresponding to the original logo image. In this way, when the original logo image is replaced based on the size-adjusted target logo image, the size of the target logo image can be adapted to the size of the logo container that carries it.

[0094] Optionally, to avoid the target logo image altering the header format, in this embodiment of the application, when replacing the original logo image based on the resized target logo image, a transparent canvas with the same size as the logo container is first created for each logo container. Then, the resized target logo image is pasted into the transparent canvas to generate a new logo image, and the original logo image is replaced based on the new logo image to obtain the target document.

[0095] It is understandable that the size information may differ for different logo containers. Therefore, a transparent canvas with the same size can be created for each logo container. Then, the target logo image with the adjusted size can be pasted into the transparent canvas to generate a new logo image that replaces the original logo image. This process ensures that after the new logo image is inserted into the image container, it does not change the aspect ratio of the logo itself, nor does it disrupt the original layout structure of the Word document header.

[0096] In some implementations, after replacing the original logo image with the resized target logo image to obtain the target document, the identification information of the resized target logo image in the target document and the identification information of the original logo image in the target document can be obtained. That is, the resized target logo image has a unique identifier in the target document, and the original logo image also has a unique identifier in the target document.

[0097] Furthermore, the identification information of the resized target logo image can be associated with the logo container, and the logo deletion interface can be called to delete the identification information of the original logo image associated with the logo container.

[0098] It is understandable that, since the logo container currently holds the target logo image, the target logo image can be associated with the logo container through the identification information. Since the original logo image has been replaced by the target logo image, the logo deletion interface can be called to delete the identification information of the original logo image associated with the logo container.

[0099] For example, please see Figure 2 This is a comparison image of a logo replacement provided as an exemplary embodiment of this application. Figure 2 As shown, the resized target logo image replaced the original logo image, and the format of the document header remained unchanged.

[0100] The following section provides a detailed explanation of the logo replacement process in Excel documents.

[0101] When the document format includes Excel documents, the Excel document parsing interface is called to parse the original document and obtain the size information of the placement unit corresponding to each original logo image.

[0102] In an Excel document, the unit is a cell (or a merged cell).

[0103] Typically, an Excel document can contain one or more worksheets. Therefore, an Excel document parsing interface can be called to parse the original document and obtain the image attribute information of each image contained in at least one worksheet of the original document.

[0104] The image attribute information may include image size, anchor point method, and anchor point position, etc., which are not limited here. The anchor point method includes fixed anchor point and non-fixed anchor point. Fixed anchor point means the image is located in a pre-defined cell in the worksheet. Typically, the logo's position in the worksheet is fixed; for example, an image located in the top-left cell is usually a logo image. If the image's anchor point method is non-fixed, then the image is considered not a logo image.

[0105] Then, for each image, the anchor point method of the image is determined from the image attribute information corresponding to the image, and the image with the fixed anchor point method is determined as the original logo image, and the size information of the cell corresponding to the original logo image in the original document is determined.

[0106] The cell corresponding to the original logo image in the original document can be either the smallest cell or a merged cell; there is no limitation on this.

[0107] Here, the row and column range of each cell in the original document can be obtained. Here, the cell can be a merged cell. For example, the row and column range of each cell in the original document can be [[min_col1,max_col1,min_row1,max_row1],[min_col2,max_col2,min_row2,max_row2],[min_col3,max_col3,min_row3,max_row3]…].

[0108] Optionally, when retrieving the row and column range of each cell in the original document, the Excel document properties interface can be used to obtain the cell's row height (Height_pt) and column width (Width_character), as well as the document's default row height and default column width parameters. If the cell's row height cannot be obtained, it is set to the default row height; if the cell's column width cannot be obtained, it is first set to the column width of the cell's previous column. If the column width of the previous column also cannot be obtained, it is set to the default column width. The default row height and default column width can be set according to actual needs.

[0109] Then, for each original logo image, determine whether the initial position of the cell containing the original logo image (e.g., [current_col, current_row]) is within the row and column range of any target cell. That is, determine whether the initial position of the cell containing the original logo icon is within the row and column range of each cell in the original document.

[0110] If the initial position of the cell containing the original logo image (e.g., [current_col, current_row]) is within the row and column range of any target cell (one of the cells in the original document), the range of the cell containing the original logo image is updated to the row and column range of the target cell. For example, the range of the cell containing the original logo image can be updated to [current_min_col, current_max_col, current_min_row, current_max_row]. Furthermore, the first unit conversion algorithm can be used to convert the range of the cell containing the original logo image into pixel units to obtain the physical size of the cell containing the original logo image.

[0111] It is understandable that the unit of the cell's row height (Height_pt) is points, and the unit of the column width (Width_character) is characters. Therefore, it may be necessary to convert them to pixels to obtain the physical size of the cell where the original logo image is located [Height_pixel, width_pixel].

[0112] As shown in formula (1), the expressions for converting the row height and column width of a cell into pixel units are as follows:

[0113] (1)

[0114] in, For column width, Column width in pixels. For high conduct, Row height in pixels.

[0115] After obtaining the physical dimensions of the cell containing the original logo image, the target logo image can be scaled according to its original aspect ratio, based on the physical dimensions of the cell containing the original logo image, to obtain a resized target logo image. The resized target logo image must meet the following conditions: the width of the resized target logo image is equal to the width of the cell, and the height of the resized target logo image is not greater than the height of the cell; or, the width of the resized target logo image is not greater than the width of the cell, and the height of the resized target logo image is equal to the height of the cell, for example, (Width2=width_pixel and Height2≤Height_pixel) or (Width2≤width_pixel and Height2=Height_pixel), where Width2 is the width of the resized target logo image and Height2 is the height of the resized target logo image.

[0116] In some implementations, when replacing the original logo image with a resized target logo image to obtain a target document, the center offset of the resized target logo image relative to the cell can be determined based on the physical size of the cell containing the original logo image and the size information of the resized target logo image. Then, based on the center offset and the row and column range of the cell, the anchor point position is determined. Finally, the resized target logo image is placed at the anchor point position, and the original logo image is deleted to obtain the target document.

[0117] It is understandable that the offset of the resized target logo image relative to the center of the cell can indicate whether the resized target logo image is located in the center of the cell. Therefore, based on the center offset and the row and column range of the cell, the anchor point position is determined, and the resized target logo image is placed at the anchor point position. This can make the resized target logo image centered in the horizontal and vertical directions within the cell, thereby improving the neatness and aesthetics of the resized target logo image in the target document.

[0118] Here, the center offset is in pixels. Therefore, the pixel-unit center offset [offset_x, offset_y] can be converted to the EMU-unit center offset [offset_x_emu, offset_y_emu] supported by Excel documents using a unit conversion formula. Then, based on the starting row and column number of the cell containing the resized target logo image, combined with the center offset [offset_x_emu, offset_y_emu], the anchor point position of the resized target logo image is determined. The Excel image insertion interface is then called to insert the resized target logo image into the anchor point position of the cell, thus completing the logo image replacement. At the same time, the original logo image can be deleted to obtain the target document.

[0119] Furthermore, after obtaining the target document, it can be saved and stored.

[0120] For example, please see Figure 3 The image shows a comparison of logo replacement in an Excel document, provided as an exemplary embodiment of this application. Figure 3 As shown, after replacing the original logo image with the resized target logo image, the document format remains unchanged, and the resized target logo image is centered in the corresponding cell.
