Problems solved by technology

[0002] At present, the drawing software does not support secondary editing. As a result, the wrongly drawn graphics need to be redrawn after saving and reopening the original file, causing inconvenience to users; at the same time, there is a problem that the fingers cannot accurately tap the screen when drawing on the mobile phone.

Embodiment

[0021] Example: such as figure 1 As shown, an Android-based secondary editing drawing method includes the following steps:

[0022] (1) Since drawing different graphics requires different canvas sizes, you can set the width and height of the canvas before entering the canvas page, and the default is the width and height of the terminal screen; when the set canvas size exceeds the size of the screen, use the canvas to move The function completes the setting of the canvas size; the canvas moving function: when drawing graphics exceeds the width and height of the terminal screen, the coordinate position of the graphics needs to be saved due to the need to modify the drawing file twice. If the graphics are not drawn on a canvas independent of the screen, After moving, the coordinate system will change accordingly, and the coordinate system will be confused after the second modification. By drawing the graphics on the canvas independent of the screen, when the canvas is moved or zo...

Abstract

The invention relates to a secondary-editing drawing method based on Android. According to the method, graph drawing process points are recorded one by one to realize secondary editability of a picture; and meanwhile, a mouse is simulated in the drawing process to move an offset point to the vertex of the mouse, so that precise drawing is realized. Through the method, secondary editing of drawingsoftware can be realized, and precise drawing on a mobile phone can be realized through a mouse simulation mode.

Description

technical field [0001] The invention relates to the field of drawing techniques and methods, in particular to an Android-based secondary editing and drawing method. Background technique [0002] At present, the drawing software does not support secondary editing. As a result, the wrongly drawn graphics need to be redrawn after saving and reopening the original file, causing inconvenience to users. At the same time, there is a problem that the fingers cannot accurately tap the screen when drawing on the mobile phone. Therefore, it is necessary to design a secondary editing and mapping method based on Android. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies, the present invention aims to provide a secondary editing drawing method based on Android. The method of the present invention records the process points of drawing graphics one by one to realize the secondary editability of the picture, and simulates the process of drawing the pi...
