Background
The portable file format (Portable Document Format, PDF for short) is an electronic file format that is independent of the operating system platform. Because of its platform-independent nature, PDF has become an ideal document format for electronic document storage and dissemination in mobile Internet for many years, and has become increasingly widely used. The PDF file format can package electronic information such as characters, fonts, formats, colors, graphics and images which are independent of equipment and resolution into one file; in addition, the file can also contain electronic information such as hypertext links, sound, dynamic images and the like, and support special files, and has higher integration level and higher safety and reliability.
Underlining in text labels is a basic function of PDF document editing, and commonly used PDF document software is supported, including Adobe, WPS, and foci, but these software only provide line colors for users to select, but cannot set or modify line widths. The existing PDF document software does not support setting or modifying the bar width for two reasons: first, the requirements for wire thickness are different in different application scenarios. If the display proportion of the PDF document is large and the line width is set too thin, it is not easy to recognize; if the display proportion of the PDF document is small, and the line width is set to be too thick and the characters are easy to be blocked, the conventional PDF document software does not provide the function; 2) The realization difficulty is high, in the definition of the PDF format, the color and the transparency are basic attributes of the marked object, but the line width is not the basic attribute of the marked object, and the line width is much higher than the color in the realization difficulty.

As shown in fig. 1, the method for setting the marking line width may include the following steps:
s101, receiving an operation command which is input by a user and is used for setting the width of the marking line through a front-end editor of a PDF document; the operation command carries the width setting parameter of the marking line.
In the step, the electronic equipment can receive an operation command which is input by a user and is used for setting the width of the marking line through a front-end editor of the PDF document; the operation command carries the width setting parameter of the marking line. Specifically, the electronic device may receive a single operation command input by a user through the front-end editor; taking the single operation command as an operation command for setting the width of the marking line; or, the combined operation command input by the user can be received through the front-end editor; the combined operation commands are synthesized into an operation command for setting the width of the marking line.
