Detailed ways

The technical solution of the present application will be described in more detail below with reference to the accompanying drawings and embodiments.

It should be noted that, if there is no conflict, the embodiments of the present application and the various features in the embodiments can be combined with each other, all within the protection scope of the present application. In addition, although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.

As shown in FIG3 , an embodiment of the present invention further provides a method for recommending document visual effects, including:

S101, determining usage information of a document, and obtaining a stacking relationship between multiple elements in the document;

S102: Based on the stacking relationship and according to the usage information of the document, determine color matching attribute information suitable for the usage information.

The stacking relationship between the multiple elements includes: the elements do not overlap each other, the elements partially overlap, the elements completely overlap, and the elements contain but do not overlap (such as the contained element visually penetrates the containing element and is located on the containing element);

The document may include a slide document; the elements may include a title box, a content box, and content in the content box in the document.

In the embodiment of the present invention, the usage information in step S101 includes one or more of the following: document usage occasion information, document characteristic information, user history usage information, and user preference color matching information.

In the embodiment of the present invention, the applicable color scheme is determined according to the document usage occasion, document characteristics, and user preferences, and automatic coloring is implemented to automatically complete the color scheme.

In the embodiment of the present invention, the step S101 of obtaining the stacking relationship between multiple elements in the document includes:

Obtaining the stacking relationship between multiple elements from a document that solidifies the description of the stacking relationship between the elements;

or,

Gets the stacking relationship between multiple elements from a document that can edit the stacking relationship between elements.

Solidifying the stacking relationship between different elements and writing it into a document, such as writing it into a built-in document of a slide show, can enrich the existing functions of the document program and optimize the user experience of the document program; writing the stacking relationship between different elements into an editable document can help users adjust the stacking relationship between elements as needed, which is flexible and convenient to use.

The stacking relationship written in the document may be calculated by a document producer (such as a template designer or a document user) based on the stacking and perspective effects of the elements.

In the embodiment of the present invention, in step S102, based on the stacking relationship and according to the usage information of the document, determining the color matching attribute information suitable for the usage information includes:

Based on the stacking relationship, determine the level of each element;

For the elements in the determined hierarchy, color feature information of each element is recommended to the user according to usage information of the document.

In an embodiment of the present invention, the color feature information of each element can be recommended to the user, and the color feature information of one or several target elements can also be recommended to the user. When recommending the color feature information of the target element to the user, it is necessary to obtain the color attribute information that has been configured in the document in advance, and make recommendations based on the color attribute information that has been configured in the document and based on constraints such as the combination relationship, distinguishability relationship, stacked display relationship, and contrast relationship between the configured color attribute information and the color feature information of the target element that needs to be configured.

In the embodiment of the present invention, the color feature information includes: saturation, hue, brightness, color matching relationship, color matching design category, and document logical relationship category.

In the embodiment of the present invention, a slide is taken as an example. When recommending a document visual effect scheme, the slide color scheme is matched in the color scheme library to select one or more suitable color schemes. The matching rules are as follows:

(1) For business scenes, choose blue, black, and gray as the main colors;

(2) If the user likes red, then the scheme with red as the main color is also selected;

(3) If the original document is dual-primary color, the dual-primary color scheme is weighted and a preset coefficient is added;

(4) If the original document has a dual background color, the dual background color scheme is weighted plus a preset coefficient.

(5) If the original document has many contrasting logical structures, the contrasting color scheme is weighted and several preset coefficients are added.

The color scheme library is a collection of pre-stored color schemes in which a number of colors are suitable for group use, the colors are visible to each other, and the colors are suitable for cascading display.

In the embodiment of the present invention, the color feature information includes the following parts:

The "color" in the color scheme refers to the color value, regardless of the recording method (there are four common color recording systems: RGB, HSL, HSV, and CMYK). For example, in the RGB system, saturation, hue, and brightness are used to represent a color. The value of black in the RGB system is (255, 255, 255).

Once the color value is determined, whether it represents a warm or cool color, a lively or dull color, and its brightness range are also determined.

The "color matching relationship" in the color scheme includes but is not limited to:

Several colors are suitable for use in groups, colors are visible to each other, colors are suitable for overlapping display, colors are similar, and colors are contrasting.

Among them, "colors are mutually visible" means that the color composition of the subsequent object and the color composition of the previous object meet the distinguishability condition: when the distinguishability condition is met, it is determined that the displayed content is visually distinguishable; when the distinguishability condition is not met, it is determined that the displayed content is visually indistinguishable.

The distinguishable condition includes: comparing the RGB color composition of the subsequent object with the RGB color composition of the preceding object, and the comparison result is greater than or equal to a distinguishing threshold.

In the embodiment of the present invention, the three components of the RGB color composition of the subsequent object can be subtracted from the three components of the RGB color composition of the previous object to obtain three differences, and the three differences are squared and summed to obtain a comparison result. When the comparison result is greater than or equal to a preset resolution threshold, it is considered that the distinguishable condition is met, that is, the subsequent object and the previous object are visually distinguishable. When the comparison result is less than the preset resolution threshold, it is considered that the distinguishable condition is not met, that is, the subsequent object and the previous object are visually indistinguishable. For example, the color scale resolution is 256, color 1, RGB (255, 255, 255), color 2, RGB (199, 237, 204), the comparison result of color 1 and color 2 is (255-199) ² + (255-237) ² + (255-204) ² , the comparison result is compared with the preset threshold to obtain the visual resolution of color 1 and color 2, and then further compared with the resolution threshold to determine whether they can be visually distinguished.

Display content can generally be divided into multiple visual levels. For example, when there are two visual levels, they can be called background and foreground, and the colors of objects in the levels can be called background color and foreground color. When there are multiple visual levels, they can be called first level, second level, etc. in the order of display. Among them, for two adjacent or alternating levels, the latter level can be called the latter level of the former level, and the former level can be called the former level of the latter level. The requirements in the embodiments of the present invention require that the background color of the displayed content must be distinguishable from the foreground color, and the color of the latter-level object must be distinguishable from the color of the former-level object.

In the embodiment of the present invention, the method further comprises:

Receive color attribute information of the target element configured by the user;

Configuring the color attribute information of the target element includes: modifying the color attribute information of one or more elements, adding the color attribute information of one or more elements, and deleting the color attribute information of one or more elements.

When the user wants to modify one or more items of the recommended color attribute information or the user modifies an element of a document or the stacking relationship between elements, the color attribute information of all elements can be modified by modifying the color attribute information of the target element.

In the embodiment of the present invention, the method further comprises:

According to the acquired color matching attribute information of all elements of the prepared document, it is determined whether the user has adopted the recommended color matching attribute information.

In the embodiment of the present invention, determining whether the user has adopted the recommended color matching attribute information according to the acquired color matching attribute information of all elements of the prepared document includes:

Calculating similarity based on the acquired color attribute information of all elements of the prepared document and the recommended color attribute information;

It is determined whether the user adopts the recommended color matching attribute information according to the similarity and a preset threshold.

The embodiment of the present invention may adopt an incentive mechanism to encourage the user to use the recommended color matching attribute information. When it is determined that the user has adopted the recommended color matching attribute information, the user is incentivized according to a preset mechanism.

In an embodiment of the present invention, first, it is determined whether the color attribute information of all elements of the completed document is one of the recommended color attribute information; the method adopted is a similarity calculation method, and the color attribute information of all elements of the completed document is verified for similarity with the recommended color attribute information; when the similarity is greater than or equal to a preset threshold, it is determined that the user has adopted the recommended color attribute information, and the user is motivated; when the similarity is less than the preset threshold, it is determined that the user has not adopted the recommended color attribute information, and a prompt message is sent to the user.

Among them, the incentives can be in the form of issuing platform points, shopping coupons, skins, etc.

In order to better recommend color schemes for users, the embodiments of the present invention pre-set color pairs, and one color can correspond to one or more color pairs. For example, white and black are a pair of preset color pairs, white and dark blue (the specific colors are determined by the composition of RGB colors) are a pair of preset color pairs, and white and red (the specific colors are determined by the composition of RGB colors) are a pair of preset color pairs. For example, the color of the subsequent object is black, and the color of the preceding object is yellow.

The embodiment of the present invention also sets series colors in advance for better visual effects and aesthetics, and the series colors are multiple colors that meet the distinguishable conditions. One color can correspond to one or more series colors, for example, red, yellow, and green (the specific colors are determined by the composition of RGB colors) are a group of series colors. For example, the same level includes multiple fill boxes, and after one fill box is filled with red, other fill boxes can be filled with series colors, such as yellow and green.

Colors are visible to each other: Colors that appear on two overlapping objects are visible to each other.

Appropriate color overlay display: the colors that appear on multiple objects that are in an overlapping relationship are visible to each other.

There is a similar relationship between colors. According to the established rules, the colors are given characteristics. For example, red and orange are similar.

There is a contrast relationship between colors. According to the established rules, the colors are given characteristics. For example, red and green are in a contrast relationship.

Color matching design categories are divided into primary colors and secondary colors.

Combined with the logical structure of the document, it is divided into: background color, mask color, font color, design effect color, and embellishment color:

1) Background color: comes from the slide background color, substrate color, and background image;

2) Font color: the color that appears on text and icons;

3) Design effect color: other colors, which are the colors that appear in the remaining objects after removing the background, substrate, mask, text, icon and other objects in the entire document;

4) Decorative colors: colors that do not appear in other groups and only appear on decorations that do not overlap any icons or texts;

5) Mask color: A color that does not appear in other groups and only appears in the mask.

"Single color, gradient color" are directly extracted from the properties of the presentation document.
