Abstract: A picture obtaining method and apparatus and a picture processing method and apparatus are provided. The method includes: obtaining a grayscale image corresponding to a first picture and a first image, where a size of the first picture is equal to a size of the first image, the first image includes N parallel lines, a spacing between two adjacent lines does not exceed a spacing threshold, and N is an integer greater than 1; translating a pixel included in each line in the first image based on the grayscale image, to obtain a second image, where the second image includes a contour of an image in the first picture; and set a pixel value of each pixel included in each line in the second image, to obtain a second picture.

Abstract: A method for generating an identification pattern, a terminal device, and the like are provided. The method includes: obtaining a first image (110), where the first image is used to represent any one of a Chinese character, an English character, and an Arabic numeral character; performing transformation on the first image based on a contour line of the first image to obtain a second image (120), where the second image includes the first image and a plurality of contour lines; and generating an identification pattern of a software program based on the second image (130). This application can improve a display effect of the identifier pattern.

Abstract: The present disclosure discloses a method for indicating port states and a switch. A main panel of the switch is provided with port indicators one-to-one corresponding to physical ports and N channel indicators. The switch further includes a main chip and a control component. The control component is configured to: receive a port state indication signal from the main chip, and parse the port state indication signal to obtain usage state information of each logical port; generate N enable signals, and control at most one enable signal to be valid at any time point; and control the states of the N channel indicators by using the N enable signals sent from the enable signal controlling module, and control the state of each port indicator according to the N enable signals and the usage state information of each logical port.
