Technical Problem

When a painting object with transparency is selected, using the existing stroke method will cause the overlay area of ​​the target painting object and the outline drawing to be superimposed, changing the color effect of the painting object and affecting the user experience.

Method used

Use the layering method and hollow outline method to create a transparent selection layer with a display level higher than the display layer where the painting object is located. Draw a hollow outline graphic according to the target painting object, and clear the overlapping area between the target painting object and the outline graphic through the clear mode or source diagram mode, so that the target painting object can be displayed through the hollow outline graphic.

Benefits of technology

Effectively retain the color effect after the target painting object is selected, and avoid color overlay, improving the user experience.

Abstract

The invention provides a display device and a drawing object selection method, and the method can respond to a selection operation instruction input by a user, create a transparent selection layer, then detect a target drawing object indicated in the selection operation instruction, and draw a hollow contour graph according to the target drawing object. Wherein the display level of the transparent selection layer is higher than the display level of the display layer where the drawing object is located, the hollowed-out contour image is a non-overlapping area formed after the target drawing object and the contour image are overlapped, and the contour image is a graph formed after the target drawing object is thickened and rendered. And finally, controlling the display to display the hollowed-out contour graph in the transparent selection graph layer, so that the target drawing object is displayed through the hollowed-out contour graph. According to the method, a layering method and a hollow outline method are adopted, and the problem that the color effect is changed when a drawing object with transparency is selected is solved.
