Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for the document typesetting layout comprises the steps of firstly constructing a template library containing various document layout styles, selecting a template according to designed screening conditions, then arranging a text typesetting mode by referring to the original form of the template, and finally realizing the diversification of the typesetting styles according to the difference of the selected templates. The method is applied to an intelligent synthesis e-commerce banner graph, and according to the content of the document input by a user and the designated layout area, the method can design various document typesetting styles in the current layout area under the condition of no manual intervention, overcomes the defect that the layout form of the document in the same template in the current intelligent synthesis banner system is single, and supports the user to set whether a position is reserved for a document modification layer or not, thereby improving the visual effect of the whole layout.
In one embodiment, as shown in fig. 1-4, the method comprises the following steps:
s100, a template library is constructed, and the template library comprises a plurality of pattern layout templates.
In the present embodiment, for a business scenario of an application, the dimension of the scenario layout change in this scenario is analyzed. And collecting the pattern layout template by taking all the dimensions covered as the standard, wherein the dimensions comprise the pattern row number, the pattern region aspect ratio, the word number of the main pattern and the like. The collected templates have clearly distinguished title types, and the titles are matched with the modification layers one by one. The template can be stored in a PSD format, so that the position information of each layer can be conveniently read. And extracting information required by the typesetting layout by the parsing template, and storing the parsed information in a JSON file format.
Specifically, according to the file layout characteristics of the E-commerce banner image and the file input format of the current intelligent synthesis banner image, file layout templates in a PSD format are collected in two dimensions of file line number title _ number and aspect ratio aspect _ ratio of a file layout area. Preferably, for the case, the title of the case is divided into a main title, a sub-title and an action word according to the level, and the modification layer corresponds to the title type one by one, wherein the text layout area is a minimum rectangular frame containing all the titles and the modification layer. And analyzing each template to extract required analysis information, including character layout area coordinates, the coordinates of the title and the modification layer, line spacing, title sequence and the like. The parsing information implicitly expresses a document layout style, and is stored in a JSON format.
S200, receiving the file information input by the user, traversing the file layout template of the template base according to the file information, and screening the optimal file layout template.
In this embodiment, the pattern layout characteristics of the application scene are combined, the pattern information input by the user is received, the pattern information includes design screening conditions, all the pattern layout templates in the template library constructed in step S100 are traversed by analyzing the pattern layout characteristics of the application scene and the pattern information design screening conditions input by the user, and the pattern layout template meeting the conditions is screened out from the design screening conditions to serve as the optimal pattern layout template.
Specifically, in conjunction with the template screening dimension of step S100,
and extracting the title number of the file lines of the file information and the aspect ratio of the file layout area, traversing all templates in the template library by taking the two dimensions as design screening conditions, and screening the templates meeting the conditions. Preferably, the file line number title _ number and the aspect ratio aspect _ ratio of the file layout template and the file line number title _ number and the aspect ratio aspect _ ratio of the file information are respectively compared, and only if the template and the file line number title _ number of the user are equal and the difference between the aspect ratios aspect _ ratio of the two is within a range of ± 0.3, the template is determined to be a proper template, namely the best file layout template.
S300, adjusting the optimal document layout template according to the document information, extracting the layout style of the optimal document layout template, and transferring the layout style to the layout area of the user.
In this embodiment, after the optimal pattern layout template is determined in step S200, the optimal pattern layout template is modified according to the information input by the user to match the template with the input information, and then the pattern layout pattern is migrated to the layout area set by the user by learning the pattern layout pattern of the template, that is, the height ratio of each layer in the entire pattern area, and keeping the height ratio unchanged.
Specifically, step S300 further includes a fine-tuning step and a layout style migration step.
For the fine tuning step, the case includes at least one line of titles, each line of the case includes text, and some lines further include a modification layer. However, in the intelligent composite banner map, the modification layer that the user requires matching of each title does not necessarily correspond to the modification layer existing in the template, for example, the user requires that each title has no modification layer or that only subtitles and action words have modification layers, so the selected optimal pattern layout template needs to be finely adjusted according to the pattern information input by the user, and the position of the modification layer is reserved in the row corresponding to the template or the modification layer in the template is deleted.
Specifically, the document information and the document layout template are respectively analyzed, and whether each line of the document comprises a modification layer is determined. And then adjusting each line of the file layout template according to the file information, and adding a modification layer or deleting the modification layer. Preferably, under a template reference system, calculating coordinates of an added modification layer or deleting a modification layer matched with a certain line of titles according to a set size rule, wherein the size rule of the added modification layer is as follows;
ornament_height＝int(1.6×title_height)；
ornament_width＝title_width+3×title_height；
wherein, the authority _ height is the height of the modification layer, the authority _ width is the width of the modification layer, the title _ width is the width of the title, and the title _ height is the height of the title.
Since the modification layer is wrapped with the title, deleting or adding the modification layer changes the line spacing between the modification layer and the upper and lower line titles. In order to keep the line distance row _ spacing [ s1, s2, s3, ] between each line of the template unchanged, in the pattern layout region text _ region _ template [ [ left, top, right, bottom ] ] of the template, the coordinates of the title [ [ tx1, ty1, tx2, ty2] and the modified layer organization [ [ x1, y1, x2, y2] are updated in sequence according to the order of the titles in the template, and the original layout pattern is restored. And simultaneously calculating the maximum value of the text box of each title, and then adjusting the width of the text box of each title to the maximum value. And finally, obtaining the layout style of the adjusted optimal pattern layout template. The specific adjustment process is as follows:
for the layout style migration step, the core is to learn the height and width ratio of the layout style of the template, i.e. the title, in the template. Determining the position coordinates of the layout region, i.e. text _ region _ in of the document layout region inputted by the user [ st _ x, st _ y, end _ x, end _ y ], and text _ region _ template of the document layout region of the template [ left, top, right, bottom ], by the following formula:
resize_w＝(end_x-st_x)/(right-left)
resize_h＝(end_y-st_y)/(bottom-top)
x1-left，y1-＝top，x2-left，y2-＝top
new_x1＝max(int(round(x1*resize_w+st_x))，st_x)
new_x2＝min(int(round(x2*resize_w+st_x))，end_x)
new_y1＝max(int(round(y1*resize_h+st_y))，st_y)
new_y2＝min(int(round(y2*resize_h+st_y))，end_y)
new_box＝[new_x1，new_y1，new_x2，new_y2]
and (3) migrating the layout style in the template, namely the coordinates box of the title and the modification layer [ x1, y1, x2 and y2] to a text-layout region text _ region _ in input by a user, and calculating to obtain the new coordinates new _ b of the new title and the modification layer, thereby completing the migration of the layout style. The line space of the template is shifted by row _ spacing ═ int (round (s _ i × resize _ h)) ], wherein i ═ 1: title _ number + 1.
S400, determining the coordinate position of the file information in the layout area, and outputting the typesetting result.
In this embodiment, the position of each title or modifier layer within the new layout area and the target line spacing are calculated, per step 300. Next, it is necessary to render the corresponding input caption in each text box, calculate the font size of each caption and the size of the real rendered text, and finally output the layout result.
In one embodiment, step S400 includes a pre-rendering step and an update adjustment step.
S410, a pre-rendering step.
Through step S300, each layer maintains the height ratio of the original template in the layout area set by the user. However, when the height of the layout area of the template is greatly different from the height of the layout area set by the user, the text box calculated according to the proportion in the template is small, so that rendered characters are small, a high character threshold value is set, and the problem of small characters is solved. And in the pre-rendering module, selecting a font, rendering according to the font, and calculating the maximum font size of each title in the text box and the size of the rendered text. And when the height of the rendered text is smaller than a preset threshold value, performing pre-rendering according to the threshold value, and recording the rendering state of each line of titles.
Specifically, according to the document information and the layout style, the text, the position of the text box, the font corresponding to each line of the document and the preset word height threshold of the line are obtained.
And rendering the text in the text box by using the initialized font size, and calculating the font height of the text by iterating the font size until the text just fills the text box.
Comparing the sizes of the word height and the preset word height threshold, and if the word height is not less than the preset word height threshold, calculating the rendering state of the text. And if the word height is smaller than the preset word height threshold value, using the preset word height threshold value as the word number, and calculating the rendering state of the text.
And outputting the pre-rendering state of each line of the file.
In an embodiment, as shown in fig. 4, in the pre-rendering process, in the horizontal mode, when the height of the layout area of the template is greater than the actual height of the layout area set and input by the user, a situation that the text box is smaller after the layout style migration occurs, and thus the font of the row of titles is smaller. A word height threshold th _ threshold, { title _ name _ i: threshold _ i }, where i ═ 1: title _ number, is set for each type of title, indicating the minimum word height that each line of titles must reach under the current layout range. For font selection, it can be set or randomly selected in combination with specific business scenario requirements. Wherein the identifiers vert _ filled and hori _ filled indicate whether the limit state has been reached in the horizontal direction and the vertical direction of the text in the text box. updated _ small indicates that rendering using the threshold thresh as the font size results in text exceeding the text box. is _ grease represents whether the height of the rendered text is greater than a threshold thresh. Preferably, the minimum value of the height and the width of the text box divided by the number of words is used as an initialization word size, the word size of the text box just filled with words and the size [ tw, th ] of the rendered text are calculated by an iterative method, the identifiers vert _ filed and hori _ filed are updated at the same time, and the pre-rendering state of each line title, that is, the value of each identifier of each line is recorded.
And S420, updating the adjusting step.
When pre-rendering titles, titles of different word counts may fill the text box vertically, or fill the text box horizontally. Compared with the original template, the horizontal filling of the text box leads to the increase of the upper and lower line spaces, and if the text box is pre-rendered according to the threshold value, the line space is reduced. Both of these conditions affect the typesetting effect, so the new calculation of font size and line spacing is required to improve the typesetting effect.
Specifically, the pre-rendering state of each line of the document is parsed.
Screening out the case with the character height of the text being larger than the preset character height threshold value, judging whether the case with the character height being larger than the text box height exists, if so, adjusting the case with the character height of the text being larger than the preset character height threshold value, reducing the character size of the case, and adjusting the line spacing between the cases in each line.
In one embodiment, according to step S410, the pre-rendering status of each line title is recorded, and when updated _ small is True, it indicates that the height of the title exceeds the text box, which results in line space reduction and even overlap with other titles. Since the input layout space is fixed, the title word size of is _ grease being True can only be reduced.
S421, setting a minimum line spacing sum threshold value min _ space _ ratio, and reserving a certain line spacing; calculating a remaining Height ratio free _ space _ ratio (Height-Height _ sum)/Height, where Height-end _ y-st _ y represents the Height of the input layout area, Height _ sum is the sum of the heights of all rendered texts,
s422, if free _ spa _ create is smaller than min _ spa _ tio, then the difference height ratio of need _ ratio _ min _ space _ ratio-free _ space _ ratio, and reduce the header with is _ grease as True to obtain the height of need _ ratio;
s423, cur _ textRatio indicates a high ratio of the title word with is _ grease being True, { title _ name _ i: cur _ ratio _ i }, i ═ 1: n, n ≦ title _ number; then the rate at which the word height per line needs to be reduced is need _ ratio _ mean ═ need _ ratio/n;
s424, prevent the word height after the title reduction from being less than the threshold ratio thresh _ ratio, calculate the ratio diff that each line of titles can be reduced:
thresh_ratio_i＝th_threshold[title_name_i]/Height
diff_i＝cur_textRatio[title_name_i]-thresh_ratio_i
Diff_set＝{title_name_i:diff_i}
i＝1:n,n≤title_number
s425, calculating the new _ th _ thermoshold of the word height which needs to be reached after the title of each line is reduced by Diff _ set according to the Diff sequence from small to large:
s426, the new _ th _ threshold is used as the initial font size, the height of the corresponding text box is changed to the threshold size, and the new font size and the size of the title are obtained through re-prerendering. Calculating a new residual space height free _ space, and if the residual space is larger than the sum of the calculated target line distances during layout migration, keeping the target line distance row _ space unchanged; otherwise, calculating the new height of each line space according to the proportional relation of the target line spaces, and updating the target line spaces row _ spacing [ s _ i/(row _ spacing) × free _ space) ], wherein i is 1: title _ number + 1.
And S430, calculating coordinate positions, calculating the coordinate positions of each line of texts and the modification layer according to the sizes of the rendered texts of the texts in the layout area, and outputting the typesetting result.
Specifically, the font size and size of each line header and the size of the modification layer are determined by the prerendering step S410 and the update adjusting step S420. And calculating the coordinate positions of each line title and the modification layer in a layout range reference system set by a user.
