Embodiment
The present invention avoids the thinking changing paintbrush, realizes paintbrush function from the angle of conversion drawing window.The present invention is explained in detail below in conjunction with accompanying drawing and embodiment.
Paintbrush implementation method of the present invention, as shown in Figure 1, comprises step:
Step 1, the width of paintbrush and the angle of inclination of relative reference orientation are set;
Step 2, the multiple comparing paintbrush width according to paintbrush width carry out convergent-divergent to drawing window in upright reference orientation, carry out reverse rotation according to the angle of inclination of the relative reference orientation of paintbrush to drawing window;
The drafting operation of step 3, monitoring mouse, the multiple comparing paintbrush width according to paintbrush width carries out convergent-divergent to the coordinate of mouse in upright reference orientation, rotates mouse coordinates according to the angle of inclination of paintbrush relative to reference orientation;
Step 4, the drafting responding mouse according to convergent-divergent and postrotational mouse coordinates on convergent-divergent and postrotational drawing window operate.
Drafting window herein refers to drawing board or the painting canvas of showing drawing effect, and this painting canvas can random variation, and namely scalable rotatable, the present invention makes the operation of paintbrush obtain paintbrush effect by the conversion of painting canvas.
As mentioned above, first the present invention arranges width and the angle of inclination of paintbrush to be achieved, the reference orientation at the angle of inclination horizontal direction X-direction in other words normally on painting canvas, paintbrush width is how many times of paintbrush width, and painting canvas is just corresponding amplifies how many times in upright reference orientation in other words paintbrush Width.Like this, paintbrush is operated, what obtain is exactly the effect of the paintbrush of one fixed width, but the mouse coordinates in upright reference orientation is also exaggerated how many times, remain unchanged to make mouse coordinates, before responding, by the corresponding multiple of reverse for mouse coordinates convergent-divergent, i.e. the multiple of the relative paintbrush width of convergent-divergent paintbrush width.
Because the angle of inclination of paintbrush also can affect drafting effect, therefore, the coordinate of mouse and painting canvas all will do corresponding rotation, and the anglec of rotation of mouse coordinates is identical with paintbrush angle of inclination, and the rotation of painting canvas is then the inverse operation that mouse coordinates rotates.As, on the relative painting canvas of paintbrush, the angle of inclination of horizontal direction is 30 °, then painting canvas should rotate-30 °, after monitoring the drafting operation of mouse, responds after mouse coordinates being rotated 30 ° again.
Paintbrush implement device of the present invention is the device corresponding with said method, as shown in Figure 2, comprising:
