Problems solved by technology

In order to make the simulated rounded corners smoother, it is necessary to reduce the size of the triangles and increase the number of triangles, but this will bring a lot of computing pressure to the drawing device
If the number of triangles is reduced in order to reduce the computing pressure of the drawing device, the simulated rounded corners will have more jagged and not smooth enough, which will affect the user's visual experience

Abstract

The application provides a method and a device of displaying a picture. The method comprises: determining a reference point associated with a preset vertex in the picture, wherein the preset vertex is an intersection point of a first edge and a second edge of the picture, and a distance from the reference point to the first edge and a distance from the reference point to the second edge are equal; determining a set of to-be-processed pixel points in the picture according to a position relationship between the reference point and the preset vertex; calculating distances between all the pixels points in the set of the to-be-processed pixel points and the reference point; and determining the pixel points, of which the calculated distances are greater than a preset distance threshold value, as discarded pixel points, and displaying the pixel points other than the discarded pixel points in the picture on a screen of a terminal device. According to the method and the device of displaying the picture provided by the embodiment of the application, a picture with smooth rounded-corner areas can be drawn in a case where utilizing basic elements to segment the picture is avoided.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and device for displaying pictures. Background technique [0002] With the continuous development of the image processing technology field, various drawing devices can be used to draw the content displayed on the picture on the display screen. The drawing device may be a display interface card (Graphics Card, graphics card for short) or a device integrated with a graphics card function (such as a TV box, a processor integrated with a graphics card function, etc.). In practical applications, pictures to be drawn can often be stored in a storage device according to a specified path, and the storage device can be integrated in the drawing device, or can be used as an independent device that can be accessed by the drawing device. When drawing the picture to be drawn, the drawing device can read the picture to be drawn from the specified path, and then ren...
