Detailed Description
The following description of the embodiments of the present application is provided by way of specific examples, and other advantages and effects of the present application will be readily apparent to those skilled in the art from the disclosure herein. The present application is capable of other and different embodiments and its several details are capable of modifications and/or changes in various respects, all without departing from the spirit of the present application. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only schematic and illustrate the basic idea of the present application, and although the drawings only show the components related to the present application and are not drawn according to the number, shape and size of the components in actual implementation, the type, quantity and proportion of the components in actual implementation may be changed at will, and the layout of the components may be more complex.
Consider that in some business scenarios, such as a doctor writing a medical record, it is desirable to hide the header and footer while writing the medical record, thus providing more screen area for writing. The header and footer can be hopefully displayed when the medical record is printed or browsed, and the integrity of the information is kept. In order to solve the above problems, the present application provides a method, an apparatus, a device, and a medium for dynamically displaying or hiding a header and a footer, which enable a user to switch between displaying and hiding of the header and footer at will by designing a set of header and footer dynamic loading mechanism based on svg elements on a web editor.
Fig. 1 is a flow chart illustrating a method for dynamically displaying or hiding a header and a footer according to an embodiment of the present invention. As shown, the method comprises:
step S101: and acquiring the electronic medical record.
In this embodiment, the acquired electronic medical records are preset and universal electronic medical records in hospital systems of a hospital, and have default format and layout characteristics of the hospital systems; in addition, the electronic medical record can be obtained by electronically scanning a paper electronic medical record held by the patient.
Because the formats of the electronic medical records are not uniform, the designs of headers and footers are also different. In order to hide headers and footers, header areas and footer areas need to be divided first in the application, specifically, header areas and footer areas and text areas of each page can be accurately divided according to setting parameters or formats of headers and footers on the back of various electronic medical records and according to a specific calculation mode.
Step S102: the heights of the header region and the footer region of each page are calculated to obtain the starting and ending positions of the header region and the footer region, respectively.
In an embodiment of the present application, the step S102 specifically includes:
A. the height at which the height of the contents in one row of the header area and the footer area is the largest is calculated, respectively, and is taken as the in-row height of the current row.
In the present embodiment, reference may be made to the scenario diagram of line height calculation shown in fig. 2. Characters such as Chinese, English, numbers and the like or characters of various combinations can be written at the positions of headers or footers, and different characters are highly differentiated, for example, English characters in figure 2 are generally shorter than literal characters. For the uniformity and accuracy of the line height calculation, the height with the largest content height in one line of the header area and the footer area is taken as the in-line height of the current line in the present application. Specifically, in determining the height at which the height of the content in one row is the largest, the middle line and the base line as shown in the figure may also be referred to make the determined height in row more accurate.
B. Calculating the row height of each row; wherein, the row height of each row is the top height + the height in the row + the bottom height.
In this embodiment, usually, in the process of editing characters, for the sake of neatness and beauty of the characters, a line space, specifically, a distance before a segment and a distance after a segment, is often set for each line of characters, or a line space multiple, for example, a numerical value such as 1 time, 1.5 times, 2 times, etc., is set, that is, a percentage of a text content height is set. Therefore, the distance before the segment and the distance after the segment or the height between the lines corresponding to each line of content are obtained by obtaining the setting parameter behind the text format, i.e. the height between the lines set by the text content, so as to obtain the top height above or before the text content of the corresponding current line and the bottom height below or after the text content of the corresponding current line, and finally the line height of each line is obtained by adding the line height, the top height and the bottom height, as shown in fig. 2.
C. Header height/footer height is the top margin + all line heights + bottom margin.
In this embodiment, the header/footer area is also usually set to a certain distance from the text area or page boundary, and the distance value is also set by default or user-defined in text editing, for example, the default is typically 3.17 cm. Therefore, the top margin and the bottom margin of the header/footer row height can be obtained by obtaining the corresponding setting parameters, and the header height/footer height in the application can be obtained by adding the margin, all the row heights and the bottom margin.
D. And finally, respectively obtaining the starting position and the ending position of the header content and the footer content.
After the header height/footer height is determined, the starting and ending positions of the header and footer can be determined.
Step S103: and respectively screening out a header area and a footer area of each page in the content of the electronic medical record according to the starting position and the ending position, and putting into a buffer svg layer to filter the header area and the footer area.
In an embodiment of the present application, step S103 specifically includes:
a) dividing each page of content of the electronic medical record according to the header end position and the starting position of the footer content;
b) and obtaining a header area, a footer area and a text area of each page through segmentation.
In this embodiment, a text area is also usually provided with a fixed range or size, and a text page is usually composed of only a header, a text and a footer, so after obtaining the header height or the footer height, or the starting position and the ending position of the header and the footer, the area between the header and the footer is the text area, and the header area, the footer area and the text area of each page can be obtained by dividing according to the starting position and the ending position of the header and the footer.
For example, the end position of the resulting header is recorded as: a1(x1, y1, y2), a2(x2, y1, y 2); the inspired position of the footer is noted as: a3(x3, y3, y4), a4(x4, y3, y 4). Then, the positions of the segmented text areas are: x: x2, y: y2, and thus the height of the text area: y 3-y 2, the width of the body area can be chosen to be the width of the buffer svg layer that is put in, since the width of the application is not affected by the header footer. As shown in fig. 3, corresponding area 1 in the schematic diagram is a header area, area 2 is a body area, and area 3 is a footer area.
c) And carrying out filtering processing of XOR calculation of an internal typesetting engine on the content of the first page containing the header area and the footer area to obtain a second page only with text content.
In this embodiment, after the header area and the footer area of each page of the electronic medical record content are screened, the header area and the footer area of each page of the screened medical record content are placed in a buffer svg layer. The data of each page block is contained in three svg elements, for example, a header, a body and a footer respectively correspond to one svg element, and n pages have 3 × n svg elements. And then carrying out XOR calculation of internal typesetting engines on the contents of the first page P1 placed in the header area and the footer area of the buffer svg layer, namely, filtering or hiding the header area and the footer area by virtue of the buffer svg layer, and finally obtaining a second page P2 only with text contents.
Wherein, svg is an image file format, and is called Scalable Vector Graphics in English, which means Scalable Vector Graphics. It is a language for describing two-dimensional graphics and drawing programs based on xml (extensible Markup language). Strictly speaking, the vector graphics language should be an open standard, and the high-resolution Web graphics page can be designed. The user can directly draw the image with the code, can open the svg image with any word processing tool, make the image have interactive function by changing part of the code, and can insert into HTML at any time to watch through a browser. As an open network standard based on text, svg can gracefully and concisely render graphics of different sizes, and seamlessly connects with other network standards such as CSS, DOM, JavaScript, SMIL, and the like. In essence, svg is relative to an image as if HTML is relative to text.
The svg images and their associated behavior are defined in XML text files, which means that they can be searched, indexed, scripted and compressed. Furthermore, this also means that any text editor and drawing software can be used to create and edit them.
General svg can provide 3 types of graphical objects: vector graphic (for example: a path composed of straight lines and curved lines), image (image), text (text). The graphic objects can also be grouped, added with styles, transformed, combined and the like, and the feature set comprises nested transformations (nested transformations), clipping paths (clipping paths), alpha masks (alpha masks), filter effects (filter effects), template objects (template objects) and other extensions (extensions).
Step S104: and moving the filtered pages to a preset template for rendering display, so that the header area and the footer area are hidden in the displayed content of each page.
In an embodiment of the present application, step S104 specifically includes:
1) pre-creating a preset template which contains a text area but does not contain a header area and a footer area;
2) adjusting the size of the preset template to the size of the text content;
3) and putting the second page obtained by processing into a created preset template for rendering and displaying so that the header area and the footer area of each page of displayed content are hidden.
In this embodiment, a new template is created first, the template does not include a header footer area but only includes a text area, and the size of the template page is the size of the content of the text area, and then the processed P2 page is placed in the created template for rendering and display.
In this embodiment, the preset template can be set to display or hide the header area and the footer area during a display or print operation, respectively.
It should be noted that, because the header area and the footer area are brought into the preset template described in this application, they can independently perform functions such as displaying or printing, and optionally set to display or hide the rendered header area and footer area when performing different functions. The medical record display method can meet the requirements of a doctor on writing medical records, the page header and the page footer are hidden, and the scene displayed by the page header and the page footer is displayed when the medical records are printed or browsed.
