Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0016] Figure 1 This is a flowchart of the color intelligent unification method according to an embodiment of the present invention; Figure 2 This is a schematic diagram of an electronic device according to an embodiment of the present invention. Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0018] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the invention described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] According to embodiments of the present invention, a color intelligent unification method is provided, such as... Figure 1 As shown, steps 101 to 102 are included below: Step 101: After obtaining the target PPT, iterate through all the shapes of all slides in the target PPT document, extract the underlying color attributes corresponding to each type of shape, obtain the color attribute set ColorFormat for each type of shape, generate a color token ColorFormatModel for the color attribute set ColorFormat, and assign a unique identifier GUID to the color token ColorFormatModel. The color attribute set ColorFormat and the color token ColorFormatModel are stored in the cache.

[0021] In this step, the file structure of the target PPT document is read. All slides are traversed in ascending order of slide number. For each slide, the shape index table is parsed to obtain the shape ID, shape type, and the enabled status of each channel (e.g., fill, line, text, glow, and shadow channels). For each channel with enabled color configuration, the corresponding shape's ColorFormat property set is extracted. The following data is written to a temporary cache space via caching: the original underlying properties of ColorFormat, i.e., the raw data ObjectThemeColor, TintAndShade, Brightness, and RGB. Each ColorFormat is assigned a unique ID to identify the shape to which it belongs.

[0022] Each cached ColorFormat raw data is converted into a readable and writable JSON data model according to a preset protocol, generating a token ColorFormatModel, and exposing the query and modification permissions of the color token to the outside world through an interface service.

[0023] Step 102: In response to the unified color operation request, perform color unification based on the unified type indicated by the operation request and the cached content.

[0024] In this step, unifying colors can include restoring the original theme color or writing back the shape color according to the token. For example, the external interface provides two atomic operations: UndoColors to restore the original color and ApplyColorToShapes to write back the shape color according to the token (supporting two paths: "theme color + TintAndShade / brightness" or "RGB + brightness").

[0025] As an optional implementation of this embodiment, color unification based on the unified type indicated by the operation request and the cached content includes: if the unified type is to restore the original color, then the original color attributes of each shape are restored based on the original data in the cached color attribute set ColorFormat.

[0026] In this optional implementation, the original color properties of all shapes are restored based on the cached original ColorFormat data.

[0027] As an optional implementation of this embodiment, color unification based on the uniform type indicated by the operation request and the cached content includes: if the uniform type is to unify the color according to the target token, then based on the target color token GUID indicated by the operation request. k The target color attribute set ColorFormat is matched from the cache with the same color token; the color configuration parameters indicated by the operation request are written into the ColorFormat field of the target color attribute set ColorFormat.

[0028] In this optional implementation, the color configuration parameters received from external input are located at the target shape using the unique ID of the color token, and the color configuration parameters are written back in batches to the ColorFormat property of the corresponding shape to achieve uniform adjustment of PPT document colors.

[0029] The methods for parameter write-back include writing back parameters based on theme color rules or writing back parameters based on custom rules.

[0030] As an optional implementation of this embodiment, writing the color configuration parameters indicated by the operation request into the ColorFormat field of the target color attribute set ColorFormat includes: writing back the theme color ObjectThemeColor, the light or dark offset information of the theme color, and the brightness adjustment information in the color configuration parameters indicated by the operation request to the ColorFormat field of the target color attribute set ColorFormat.

[0031] As an optional implementation of this embodiment, writing the color configuration parameters indicated by the operation request into the ColorFormat field of the target color attribute set ColorFormat includes: writing back the customized RGB and brightness adjustment information in the color configuration parameters indicated by the operation request to the ColorFormat field of the target color attribute set ColorFormat.

[0032] Write the color configuration parameters to the ColorFormat field of the target shape to complete color unification, including: i) Theme color path: Write in batches according to the configured ObjectThemeColor, TintAndShade, and Brightness parameters to achieve a unified color based on the theme color; ii) Custom RGB path: Calculate color values ​​and write them in batches according to the configured RGB and Brightness parameters, automatically hide the ObjectThemeColor constraint, and achieve a unified color based on the custom color.

[0033] This embodiment eliminates the need for manual document traversal or repeated color parameter adjustments. Simply pass configuration parameters through the ApplyColorToShapes interface to unify the colors of hundreds or thousands of shapes, reducing operation time from "hours" to "milliseconds." It is especially suitable for complex PPT documents with multiple slides and shapes, significantly saving labor and time costs.

[0034] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
