Here, in the drawing operation process, the user needs to continue to perform new drawing after reviewing, restoring and drawing the process for the efficiency of the operation, that is, after step S120, the current page forms a first drawing image after restoration, at this time, the user continues to perform a new round of drawing on the current page, and generates a second drawing image according to a second drawing gesture, so that the user can continue to perform the drawing operation while learning to review;
It should be noted that each page may include a plurality of drawing images, and the number of the drawing images included in each page may be determined according to the actual drawing situation of the user, and the new page may be switched to draw on the new page again;
according to practical situations, a complete picture to be drawn may be too complex, the drawing process is forced to be interrupted, and the like, and the complete picture cannot be drawn at one time, that is, the drawn picture may include several drawn images (a plurality of drawn images on the same page), and a user may want to restore the drawing process of the complete picture or restore a partial picture including a plurality of drawn images at one time during the restoration process, where the second drawing instruction includes at least one identifier, and the method further includes:
step S140: and associating the first drawing image with the second drawing image through the association relationship between the identifier of the first drawing image and the identifier of the second drawing image, so that the first drawing image and the second drawing image are re-formed on the current page under the condition that the second drawing instruction is triggered.
The method comprises the steps that the drawn images are associated according to the relation of marks among the drawn images, wherein the association comprises a drawing time sequence relation on the same page, namely the drawn images on the same page of the image to be restored can be selected from a plurality of images through the association, the drawn images are restored according to the drawing time sequence relation, the second drawing instruction comprises corresponding marks of the images to be restored, generally speaking, the images to be restored belong to the same page, the images are combined into a complete image or a part of the complete image, the drawn images can be restored according to the time sequence order through triggering of the second drawing instruction once, and a user can conveniently review the whole drawing process of the image;
It should be noted that the association relationship is an exemplary embodiment, and the association relationship further includes a layer association relationship, a coordinate association relationship, and a color value association relationship, and may be specifically set according to an actual situation of a user;
in some possible embodiments, since the picture to be drawn is too complex, such as a building map, a landscape, a person, and the like, even if a part of the picture is drawn, each part of the drawn image is still very complex, such as a long reduction process, and difficulty in learning and reviewing is high for a beginner, the method according to the embodiment of the present invention separates the complex drawn image according to the preset personality parameters, and can reduce only a part of sub-images in the drawn image, so as to facilitate the beginner to learn the reduction process, before step S110, the method further includes:
step S100: and separating and extracting the subimage of the first drawing image according to the preset individual parameter so as to restore the subimage when the second drawing instruction is triggered.
Step S100 further includes:
and S310, separating and extracting the corresponding part of the first drawing image according to the preset individual parameters to obtain the subimage, so that the corresponding part of the subimage is restored from the first drawing image when the second drawing instruction is triggered.
