in step 101, a predetermined target template is loaded in a candidate picture.
In this embodiment of the present application, one or more images may be pre-stored in the terminal device, where in an optional implementation manner, the step 101 may include:
step 101: and loading a given target template in the candidate pictures.
In this embodiment, when performing text editing on a picture to be edited, a layer is set above the picture to be edited, a predetermined input frame is called in the layer to serve as a target template, the input frame may be in various shapes, such as a rectangle, a rounded rectangle, a circle, etc., a display area including editable characters is included in the input frame, after the characters input by a subsequent third-party input method are extracted, the characters are filled in the display area in real time, and thus a target character string input by the third-party input method in real time can be displayed in the target template.
After loading the target character string in the target template, displaying the layer of the target template above the picture to be edited, and displaying the effect of character editing in the picture to be edited.
Step 102: randomly selecting from a preset style library in real time, and determining a text style corresponding to a current character string in the target template, wherein the current character string is formed by extracting characters input by a third-party input method in real time.
A style library for storing a plurality of character styles is prestored in the terminal, the character styles represent various corresponding styles of input characters, and each character style is structurally stored in the style library. The text style is defined according to the display attribute of the characters, wherein the display attribute at least comprises: the color, the font size, the bottom shadow, the underline, the inclination and other corresponding attributes represent the appearance style of the characters, so that when the characters are added into the picture to be edited for typesetting, the display effect of displaying various styles for the target character string is obtained, and the user experience is enriched.
Extracting the current character string in real time from a third-party input method which is being used by a user, and randomly selecting a text style from a style library to apply the current character string.
1. For the Chinese input method, extracting the first candidate item as the current character string and inputting the current character string into the display area of the target template, randomly selecting the first candidate item from the style library in real time, and subsequently applying the selected character style to the first candidate item, thereby displaying the first candidate item in the target template in various character attributes of Chinese form, such as colors, fonts, word sizes and the like.
In other embodiments, when the first candidate is not the character string that the user wants to get on the screen, the user may also use the screen as a trigger to get the current character string when the user inputs. Extracting the Chinese characters on the screen from the input method, randomly selecting corresponding text patterns from the pattern library in real time, and displaying the Chinese characters on the screen in the target template according to the text patterns.
In another embodiment, each Chinese character in the first candidate item and/or the Chinese character on the screen is respectively used as a current character string, the character patterns of the current character string are randomly selected from the pattern library for rendering in real time, namely, each Chinese character is used as a unit, the corresponding character pattern is called from the pattern library for rendering, and the display patterns of each Chinese character are different in each target template, so that various display effects are formed, and the visual experience and the user experience of the user are improved.
2. For the English input method, candidate current character strings are input into a display area of a target template in real time, simultaneously, the candidate current character strings are randomly selected from a style library in real time, and then the selected character styles are applied to the current character strings in the display area, so that the current character strings are displayed in the target template in various English colors, fonts, character sizes and other character attributes.
In other embodiments, detecting a time interval corresponding to the third input method when the third input method is input;
dividing the time interval; when the time interval is longer than the set duration, the third party input method is stopped in the input process, the possibility of sentence breaking is high, a text pattern is selected from the pattern library at random, the next sentence input again after the time interval is rendered by adopting other text patterns, and the next sentence rendered by adopting other text patterns is displayed in the target template;
when the time interval is smaller than the set time length, the third-party input method is indicated to be free from pause in the input process, the possibility of sentence breaking is low, the current character string is continuously rendered according to the currently applied character style, the current character string keeps the character style unchanged, and the consistency of the character style is maintained.
In another embodiment, the current character string is calculated according to single words, namely, the single words of the current character string are calculated respectively, the text patterns are randomly selected from the pattern library respectively, and the words are rendered in real time respectively. Specifically, when the third-party input method is detected to be input into a space or a punctuation, corresponding text patterns are randomly selected from a pattern library in real time, character strings input after the space or the punctuation are rendered, and the character strings input into a target template are displayed in different text patterns by taking words as units.
Specifically, when character patterns are randomly selected from a given pattern library, each character pattern is selected in a random mapping mode, namely each character pattern in the pattern library is mapped to a section of 0-1 in an associated mode according to a corresponding sequence number mark. When the character patterns are selected, a random number generation algorithm is adopted to generate a 0-1 random number, and the random number is mapped to a certain character pattern, so that the character patterns in a pattern library are selected randomly.
Step 103: rendering the current character string according to the character style to form a target character string;
in this embodiment, the text style encapsulates the display attribute corresponding to the character in json form, including: color, font size, whether bottom shadow is included, whether underline is included, whether inclination is performed, whether bottom shadow is present, whether thickening is performed, and the like;
the style library is stored in the terminal local, the character attributes are arranged in a permutation and combination mode, and the style library is packaged in a json mode uniformly after the arrangement is finished and stored in the style library. When the current character string is rendered, the json is called to analyze, the display attribute in the json is analyzed and the current character string is applied, and the current character string is applied according to the attribute such as color, bottom shadow, font size and the like defined in the json to form a rendered target character string, so that a richer visual effect is provided.
Step 104: and displaying the target character strings row by row in the target template.
And filling the rendered target character string into an editing area of the target template. Because the size and the size of the editing area are fixed, the system API is called to zoom and line feed the target character string and other character strings which are input into the editing area, so that the target character string and the other character strings which are input into the editing area are all displayed in the target template.
In this embodiment, the specific steps are:
acquiring the real-time corresponding size and/or character number of the target character string;
and scaling and line-wrapping the target character string according to the display area in the target template and the corresponding size of the target character string, so that the input target character string fills the display area in the target template.
When scaling and line feed are carried out, the input characters can be compared with the corresponding sizes of the display areas according to the number of the input characters, and the details are as follows:
extracting a display area in the target template and the number of characters corresponding to the input target character string, and calling a system API to perform line feed and reduction on the word size corresponding to the target character string when the number of characters is larger than the number of characters correspondingly accommodated in the display area, so that the input target character string fills the display area in the target template;
And extracting the corresponding size of the display area in the target template and the corresponding size of the target character string, and when the corresponding size of the display area is smaller than the corresponding size of the target character string, wrapping and shrinking the target character string according to the corresponding size of the display area, so that the input target character string fills the display area in the target template.
Extracting a display area in the target template and the number of characters corresponding to the input target character string, and calling a system API to amplify the word size corresponding to the target character string when the number of characters is larger than the number of characters correspondingly accommodated in the display area, so that the input target character string fills the display area in the target template;
and extracting the corresponding size of the display area in the target template and the corresponding size of the target character string, and amplifying the target character string according to the corresponding size of the display area when the corresponding size of the display area is larger than the corresponding size of the target character string, so that the input target character string fills the display area in the target template.
The input target character string fills the display area in the target template, specifically:
The filling ratio of the input target character string in the display area of the target template is smaller than the first preset ratio and larger than the second preset ratio.
For example: setting the filling ratio of the input target character string in the display area of the target template to be smaller than 80% or larger than 120%, and if the input target character string is not in the preset filling ratio range, scaling the target character string until the input target character string in the display area of the target template accords with the preset filling ratio.
After loading the target character string in the target template, displaying the layer of the target template above the picture to be edited, and displaying the effect of performing text editing in the picture to be edited. Of course, after the target character string is displayed in the target template, the candidate picture can also be triggered by the user again. Specifically, a layer is newly built above the layer where the target template is located, and other templates are loaded in the newly built layer for character string input by a user, so that a plurality of target character strings are displayed in the candidate pictures, and display information of the edited pictures is enriched.
In this embodiment, a predetermined target template is loaded in a candidate picture; randomly selecting from a preset style library in real time, and determining a text style corresponding to a current character string in the target template; the current character string is formed by extracting characters input by a third-party input method in real time; rendering the current character string according to the character style to form a target character string; and displaying the target character strings row by row in the target template. According to the embodiment of the application, when the edited picture is added with the characters, the input target characters are automatically displayed in various random patterns, a user does not need to manually operate and select the character patterns, the typesetting effect of the multiple character patterns can be rapidly achieved, the display information of the edited picture is enriched, the operation efficiency of the user is improved, and the personalized requirements of the user are met.
In another alternative embodiment, the character input is performed in the candidate pictures,
step 201: loading a given target template in the candidate picture on the candidate picture;
in this embodiment, the user performs text editing on the picture shown in fig. 2 as a candidate picture, invokes a hexagonal input frame as a target template,
step 202: randomly selecting from a preset style library in real time, and determining a text style corresponding to a current character string in the target template;
the corresponding json style is selected in real time by adopting a random number generation mode, and the display attribute corresponding to the json style selected in the embodiment is as follows: font: bold, word size: 30pt, color: black, background: no, underlined: no, tilt: no. … …
Detecting a corresponding time interval when the third party input method is input, wherein in the embodiment, the set time interval is 0.3s, and extracting the "laughter of haha" input in real time from the third party input method, namely, the text style corresponding to the current character string "laughter of haha" is: font: bold, word size: 30pt, color: black, background: no, underlined: no, tilt: no … … and the time interval for detecting each character input does not exceed 0.3s.
Step 203: rendering the 'laugh with the haha' according to the character style, loading the display attributes corresponding to the haha's laugh with the haha's laugh, the haha's laugh with the haha's no laugh, the haha's no underline, and the haha's no inclination, as shown in fig. 2.
Step 204: displaying the target character string row by row in the target template
In this embodiment, the width corresponding to the target character string, that is, the width occupied by 7 character sizes of 30pt in the target character string "haha joke" is 210pt. In an initial state, the display area in the hexagonal target template is 3 rows, the width of the first row is 100pt, the width of the second row is 160pt, and then the system API is called to start line feed of the fourth character laugh of the target character string, the first row displays the laugh, and the second row displays the laugh continuously, so that the laugh continuously of the target character string is displayed in the hexagonal target template.
As shown in fig. 3, when the character 'true lovely' input by the user in the third input method in real time is continuously extracted, detecting a time interval correspondingly generated when the third input method is input; in this embodiment, the time interval is set to 0.3s,
After detecting that the user inputs the character string 'haha laugh is continuously stopped' for 0.4s, randomly selecting the character string from a style library, and determining the character style corresponding to the current character string 'true lovely'. In this embodiment, the display attribute corresponding to the json style selected is: font: bold, word size: 36pt, color: dark green, bottom shadow: no, underlined: has, slope: … … is provided with
Rendering the current character string 'true lovely' according to the display attribute corresponding to the json style, namely setting the font of the current character string 'true lovely' as a bold type, setting the font size as 36pt, setting the color as dark green, setting the underlined and inclined style, and obtaining the rendered target character string 'true lovely'.
Meanwhile, the width corresponding to the target character string is acquired, namely the width occupied by 3 character sizes of 36pt in the target character string 'true lovely' is 108pt. In an initial state, the width of the second line is 160pt, the last character string is "haha laugh is continuously" 120pt in the second line, then a 36pt character can be contained in the remaining 40pt of the second line, namely, the second character of the target character string can be changed by calling the system API, the second line shows "true", and the third line shows "lovely", so that the target character string can be shown in the hexagonal target template.
When continuously extracting characters 'good want to strongly and strongly to the one-touch' input by a user in real time by a third-party input method, detecting a time interval correspondingly generated when the third-party input method is input;
as shown in fig. 4, if a pause of 0.5s is detected after the user inputs the character string "true lovely", a random selection is additionally performed from the style library, and the text style corresponding to the current character string "good-looking deep one-touch" is determined. In this embodiment, the display attribute corresponding to the json style selected is: font: regular script, word size: 30pt, color: red, coarsening: there are, underlines: no, tilt: no. … …
Rendering the current character string 'good want to strongly and strongly to the first aspect' according to the display attribute corresponding to the json style, namely setting the font of the current character string 'good want to strongly and strongly to the first aspect' as a regular script, setting the font size as 30pt, setting the color as red, and setting a thickened style to obtain the rendered target character string 'good want to strongly to the first aspect'.
Meanwhile, the width corresponding to the target character string is obtained, namely, the width occupied by 8 character sizes of 30pt in the target character string 'good want to strongly surround' is 240pt. In the initial state, the width of the third line is 100pt, the last character string is "true lovely" and 80pt is already occupied in the second line, and 240pt of the target character string which is not lower is accommodated in the remaining 20pt of the second line. At this time, the system API is called to scale the display area in the initial state, that is, to increase the number of lines in the display area, and at the same time, to uniformly typeset the inputted character strings, to uniformly scale the inputted character strings according to the size of the original characters, and to count the number of inputted characters and the width corresponding to each character, in this embodiment, to reduce each character to 80% of the original, as shown in fig. 4, the inputted target character string "like strongly and strongly to one touch" is completely displayed in the display area in the hexagonal input template in another text style.
In this embodiment, when adding text, a predetermined text style is randomly called from a style library, and at the same time, a time interval generated correspondingly when a user inputs in real time is detected, a current character string is divided by taking an input pause as a unit, and a corresponding text style is called to render the current character string, so that each corresponding clause when inputting pause is automatically displayed in a target template in different text styles, and the user can quickly realize typesetting effect of multiple text styles without manually editing the text styles, thereby enriching display information of the edited picture, improving operation efficiency of the user, and meeting individual requirements of the user.
In another embodiment, when character input is performed in the candidate picture,
step 301: loading a given target template in the candidate picture on the candidate picture;
in the embodiment, when the user edits the candidate pictures, a layer is arranged on the candidate pictures, a target template which is hexagonal in shape and gray in background is called,
step 302: randomly selecting from a preset style library in real time, and determining a text style corresponding to a current character string in the target template;
In this embodiment, characters input in real time by the third-party input method are extracted in real time, the input character strings are segmented in units of rows, the character strings in the rows are used as current character strings, real-time selection is randomly performed in the json library, and the obtained random character patterns correspond to texts in each row respectively.
Specifically, the json library in this embodiment is as follows:
and randomly calling the corresponding json from the json library as the current line, namely the text style corresponding to the current character string.
In other embodiments, the current character string may be calculated according to a single character, and the single characters of the current character string may be respectively and randomly selected from the style library to perform real-time rendering, that is, the display attribute of each character loaded is different, then the target character strings forming different character styles are displayed in the target template, so that the display effect is enriched, meanwhile, the process of editing and typesetting characters by the user is omitted, and the input efficiency of the user is improved.
Step 303: rendering the current character string according to the character style to form a target character string;
in this embodiment, as a user continuously performs character input, rendering is performed on a current character string of each row by calling a corresponding text style in units of rows, that is, each display attribute corresponding to the text style is loaded on the current character string, and each character in the current character string is rendered to form a target character string.
If the current character string is input to the last row, the realization is performed. ", and the sixth row randomly selected text style is:
"type":0,
"textSize":20,
"textColor":"#FFFF0000",
"colorGroup":0,
"font":"fonts/Orbitron-Medium.ttf"
the sixth row is implemented according to the display attribute therein. "font size is set to 20 (" textSize ": 20), font is set to Orbitron-Medium (" font ":" nts/Orbitron-Medium. Ttf "), and text color is yellow (" textColor ":" # FFFFFF00 "), forming the target string" implementation as shown in fig. 5. "
