The embodiment of the application discloses a display control method of a drawing board. Referring to fig. 1, as an embodiment of a display control method of a drawing board, the method includes the following steps:
Specifically, the drawing board may be an electronic drawing board, or may be drawing board software installed in an intelligent terminal, where the intelligent terminal has a touch screen. The painting brush can be a capacitive pen or an electromagnetic pen, and the electronic drawing board or the intelligent terminal provided with the drawing board software is provided with a touch screen matched with the painting brush type. The touch display area of the drawing board can be understood as a whiteboard area in the drawing board, and the whiteboard area is used for drawing by a user and displaying the drawn pattern. The drawing board is provided with a special painting brush, current signals generated by painting brush contact and non-painting brush contact (such as finger contact and contact generated by a non-special painting brush) are different, and the type of the current contact can be judged by judging the current signals and the change of the current signals.
And 102, when the type of the contact is judged to be non-brush contact, obtaining a contact path of the current contact based on the continuity of the current contact.
Specifically, when the processor determines that the type of the current contact is the non-brush contact, the processor obtains the contact path of the current contact based on the continuity of the current contact, for example, the processor obtains the contact path of the current contact based on the initial position and the final position of the current contact and the position change in the contact process.
And 103, comparing the contact path with a preset path library to obtain the matching degree of the contact path and the contact path corresponding to the erasing instruction.
Specifically, the preset path library stores a plurality of contact paths, some specific contact paths of the non-brush contact correspond to specific shortcut operation instructions, and the "some specific contact paths" may be preset by the system or may be set by the user. When the contact mode is non-brush contact, the user may issue a shortcut operation instruction. The processor compares the contact path with a preset path library to obtain a matching degree of the contact path and the contact path corresponding to the erasing instruction, where the matching degree may be understood as an overall similarity between the current contact path and the contact path corresponding to the erasing instruction, and the greater the similarity between the current contact path and the contact path corresponding to the erasing instruction, the higher the matching degree is correspondingly.
Specifically, when the matching degree is greater than the preset value, it is indicated that the user issues an erasing instruction, at this time, the processor changes the touch display area into a first display area and a second display area, a dividing line is left between the first display area and the second display area, the processor displays the current drawing pattern in the first display area, and displays a plurality of erasing candidate patterns in the second display area, and the user can select one of the erasing candidate patterns in the second display area. The display area of the first display region is larger than the display area of the second display region, and in one embodiment, the display area of the first display region is three times larger than that of the second display region. The erasing candidate pattern is a pattern which is generated by the system according to the erasing instruction and is used for being selected by the user and deleting at least part of the segment of the last drawn line.
And 105, when one of the erasing candidate patterns in the second display area is clicked, increasing the display area of the second display area to enable the adjusted display areas of the first display area and the second display area to be the same, and amplifying the touched erasing candidate pattern to fill the second display area.
Specifically, in order to facilitate the user to compare the erased pattern with the current pattern, when one of the erased candidate patterns in the second display region is clicked, the processor increases the display area of the second display region so that the adjusted display areas of the first display region and the second display region are the same, enlarges the touched erased candidate pattern to fill the second display region, and at this time, the erased candidate pattern has the same size as the drawn pattern, thereby facilitating the user to compare.
And 106, hiding the first display area and covering the second display area with the touch display area when a certain part of the second display area receives two clicks within a preset time length.
Specifically, the preset time period may be set to 2 seconds, after the click is received in the second display area for the first time, the processor enters countdown, and if the click is received again in the preset time period, two clicks received in the preset time period are satisfied. When a certain part of the second display area receives two clicks within a preset time length, the processor hides the first display area and covers the second display area with the touch display area, and the selected erasing candidate pattern is used as a pattern of subsequent drawing, so that an erasing instruction is completed.
In the application, when a user needs to erase, an erasing instruction can be sent by drawing a specific shortcut path, so that the user's operation always stays in a touch display area of the drawing board, and an erasing button or an erasing control does not need to be found. Meanwhile, in the application, a plurality of erasing alternative schemes can be automatically recommended for the user, the user can select a proper erasing alternative pattern according to needs, the problem that lines erased in the prior art are too long or too short is solved, and the experience of the user in use is improved.
