S105: the altering content is displayed in the picture.
In the embodiment of the invention, when the picture exists in the opened document, the electronic equipment can judge whether a correction instruction for the picture is received or not. If so, the user selected correction tool may be determined. Then, a movement track of a cursor carrying the mark of the altering tool in the picture is determined. Then, based on the altering tool, the motion trail and the color selected by the user, altering content corresponding to the motion trail can be generated and displayed in the picture. Therefore, the content at the corresponding position in the picture can be shielded through the altering content, and the effect of altering the picture is achieved. And the picture content of the picture is not required to be modified by means of third-party processing software, so that the picture content can be modified simply and quickly, and the user experience is improved.

Assume that a PDF document is opened in the electronic device, and a picture is stored in the PDF document. In the prior art, when a picture of the PDF document needs to be altered, the picture needs to be derived from the PDF document. And then, opening third-party picture processing software, and modifying the picture content of the picture by using the picture processing software, so as to realize correction of the picture. And then, replacing the picture in the PDF document by the modified picture. This kind of mode is wasted time and energy and difficult realization, has influenced the user experience of altering the picture in the document.
In the embodiment of the invention, the electronic device can determine whether the picture object (i.e. the picture identifier) exists in the document content of the PDF document through the document structure of the PDF document. In this embodiment, after the electronic device opens the PDF document, the electronic device may determine that a picture exists in the PDF document. The electronic device may then determine whether a correction instruction for a picture in the PDF document was received.
When receiving a user click on a correction fluid option displayed in PDF office software, it may be determined that a correction instruction for a picture in the PDF document is received. The user may then select a correction tool under the correction fluid option. Wherein the correction tool under the correction fluid option comprises: the straight line altering tool, the curve altering tool, the rectangular altering tool, and the circular altering tool are of course not limited thereto.
Assuming that the user selected correction tool is a curve correction tool, the electronic device may display a small curve in the upper right corner of the mouse cursor to indicate that the user selected the curve correction tool at this time. In addition, the user can set the line width parameters of the curve correction tool as follows: coarse (e.g., 1 cm).
After the correction tool and the parameter value corresponding to the correction tool are determined, the electronic device can detect whether the position of the cursor is located at the position of the picture or not, and determine whether a long-press instruction of the user on the mouse is received at the moment. If the position of the cursor is detected to be positioned at the position of the picture and the long-pressing instruction of the user to the mouse is detected, the motion track of the cursor in the picture, namely the track formed by the points where the cursor actually stays, can be determined. Then, a target curve can be generated according to the curve correction tool, the line width parameter and the motion trail.
The electronic device may then render the target curve with the color selected by the user (e.g., red). Thus, the target curve after color rendering is the correction content. The altering content may then be displayed in the picture. In this way, the content (such as characters) at the corresponding position in the picture can be shielded by the altering content, so that the effect of altering the picture is achieved. And the picture content of the picture is not required to be modified by means of third-party processing software, so that the picture content can be modified simply and quickly, and the user experience is improved.
