Abstract: There is provided a device for editing a PDF file, including a display, a non-volatile storage medium, a memory and a processor. The non-volatile storage medium stores a computer program. The memory provides an environment for operations of the computer program in the non-volatile storage medium. The processor runs the computer program to parse the PDF file to obtain information of characters, generate character sets according to features of the characters, generate line sets according to heights and horizontal positions of the character sets, generate paragraph sets according to a height and a horizontal position of each line of the line sets, generate text region sets according a height and a horizontal position of each paragraph of the paragraph sets, and control the display to show the text region sets in the PDF file as editable text regions.

Abstract: There is provided a method for determining text blocks of a PDF text, including: acquiring information of characters of the PDF text; performing an initial division according to gap outliers of the PDF text in a transverse direction and a longitudinal direction, and adding block tags of first text blocks to the information of characters; sequentially processing inaccurate lines and inaccurate words in each first text block according to baselines of characters, character lengths, character spaces and character indexes; performing a baseline arrangement on lines of the PDF text; sequentially comparing two lines to form second text blocks; and sequentially comparing two second text blocks to identify whether to perform a secondary merging and a secondary division.

Abstract: The present disclosure provides a method and electronic apparatus for modifying pages of an electronic document, and the method is performed by the electronic apparatus and comprises the following steps: opening a first user operation interface; detecting whether a first input region is selected; when it is detected that the first input region is selected, displaying a plurality of first pages of a first electronic document on a page preview region and determining a first page change position located in the plurality of first pages according to a first operation event; detecting whether a second input region is selected; when it is detected that the second input region is selected, displaying a plurality of second pages of a second electronic document on the page preview region and determining at least one second page of the plurality of second pages according to a second operation event; and adding the at least one second page to the first page change position according to a third operation event.

Abstract: An online signing system and method, a computing apparatus, and a computer-readable recording medium are provided. An assigned task is generated by a task assignment apparatus to the computing apparatus. The computing apparatus generates a signing request based on the assigned task to be transmitted to a client apparatus. The client apparatus downloads an assignment file from a storage database based on the signing request to display the assignment file on a display. The client apparatus receives an input via an input unit to generate a signature object on the assignment file, and transmits the signature object to the computing apparatus. After receiving the signature object, the computing apparatus combines the signature object and the assignment file to obtain a signed file, and transmits the signed file to the storage database.

Abstract: An online signature system, method, and an electronic apparatus are provided. Through a remote conference server, an electronic apparatus and another electronic apparatus perform a remote communication procedure. In a process of performing the remote communication procedure, a signature task is transmitted to the electronic apparatus through the remote conference server. The electronic apparatus is connected to an electronic signature server based on the signature task, and displays an assignment file transmitted by the electronic signature server on a display. In response to receiving a signature object associated with the assignment file, the signature object is transmitted to the electronic signature server, so that the electronic signature server combines the signature object with the assignment file to obtain a signed file.

Abstract: A capture-and-paste method is implemented by a processor of an electronic device having a display unit. The processor executes at least one application and correspondingly enables display of at least one application window. The capture-and-paste method includes: defining a transparent working zone superimposed on the application window; moving the working zone onto a user-selected part of the application window; capturing the user-selected part of the application window to result in captured content; moving the working zone onto another user-selected part of the application window; and pasting the captured content onto the another user-selected part of the application window.
