Fig. 1 is a flowchart illustrating a method for previewing pictures in a target terminal according to an aspect of the present application, where the method includes: S100-S300, wherein in S100, an image to be processed is obtained, and the image to be processed is compressed to obtain a compressed image; in S200, carrying out color approximation processing on the compressed image to obtain a compressed image after the color approximation processing; in S300, the compressed image after the color approximation processing is converted into a target code based on a preset code format, and the target code is input to the target terminal, so as to complete the preview display of the image to be processed. So that pictures are previewed directly using the ssh remote terminal. It should be noted that the numbers in the above steps do not represent the execution order.
Specifically, in S100, an image to be processed is acquired, and the image to be processed is compressed to obtain a compressed image. The user can acquire the image to be processed in the upper computer and perform image compression processing, wherein the image compression processing is lossy compression, and the image to be processed is compressed to obtain the thumbnail of the image to be processed, so that the subsequent processing of the image to be processed can be efficiently completed, and system resources are saved. The computer language used in the present application may be Python.
In S200, color approximation processing is performed on the compressed image to obtain a compressed image after the color approximation processing. Here, the number of color types in each pixel in the compressed image is 1600 ten thousand, for example, in the upper computer, and in the ssh remote terminal, for example, Xterm, only 256 color types can be displayed, so that the color of each pixel in the compressed image needs to be color-approximated, for example, a weight calculation manner is used to determine the corresponding approximate color of the color type in the compressed image in the 256 colors, and all the color types in the ssh remote terminal are traversed to complete the color approximation of the pixel color of a single compressed image, so as to more accurately display the preview image in the ssh remote terminal.
In S300, the compressed image after the color approximation processing is converted into a target code based on a preset code format, and the target code is input to the target terminal, so as to complete the preview display of the image to be processed. Here, the preset code format may be a code format that can be directly read by the target terminal, for example, when the target terminal is an ssh terminal, xterm codes are used as the preset code format to convert the parameter information corresponding to each pixel in the compressed image after color approximation into the target codes in the preset code format one by one, so that the target terminal can directly read the target codes, and the target terminal can directly display the image to be processed after color approximation after directly reading the target codes, thereby avoiding remote downloading of the original image, and saving time and system resources.
In an alternative embodiment of the present application, the target terminal comprises a ssh terminal or a remote device supporting display of 256-color images. Here, the target terminal may be an xterm terminal or a preview picture in a ssh remote terminal supporting an analog xterm terminal, such as securechrt.
In an optional embodiment of the present application, in S200, a color of each pixel of the compressed image is obtained, whether a historical approximation processing result exists in the color of a single pixel is determined, and if yes, color approximation processing is performed on the compressed image based on the historical approximation processing result in the target terminal; and if not, performing color approximation processing on the compressed image based on the color parameters set in the target terminal.

If not, performing color approximation processing on the compressed image based on the color parameters set in the target terminal, for example, when the types of the colors set in the target terminal are 256, calling the related parameters of the 256 colors, and performing color approximation processing on the compressed image based on the related parameters of the 256 colors, so as to more accurately display the preview image in the ssh remote terminal.
In an optional embodiment of the present application, in S200, RGB values corresponding to colors of each pixel in the compressed image are determined; and carrying out color approximation processing on the color of each pixel based on the RGB numerical value and the color parameter set in the target terminal. Here, an RGB value corresponding to each pixel color in the compressed image is determined, wherein the RGB value is a composite parameter set of values of a red channel (R channel), a green channel (G channel), and a blue channel (B channel), the RGB value corresponding to the color of each pixel in the compressed image is determined, then, an approximate color closest to the color of the single pixel may be determined based on comparing the RGB value of the color of the single pixel with corresponding parameters of all colors in a target terminal, and the color of the single pixel may be updated using the approximate color to complete a color approximation process.
In an optional embodiment of the present application, in S200, the color parameters set in the target terminal include color parameters corresponding to a plurality of preset colors, all differences between the RGB values corresponding to the color of each pixel and the color parameters corresponding to all the preset colors are calculated, and the preset color with the smallest difference is determined as an approximate color; and updating the color of each pixel by using the approximate color to complete color approximation processing. Here, the color parameters set in the target terminal include a plurality of color parameters corresponding to predetermined colors, for example, RGB values corresponding to 256 colors, a difference between the RGB values corresponding to the color of a single pixel and the RGB values corresponding to all the predetermined types of colors is calculated, and the color of the single pixel is updated by taking the predetermined type of color with the smallest difference as the approximate color.
In an alternative embodiment of the present application, the color of each pixel in the compressed image and the corresponding approximate color pair are stored as historical approximation processing results. The color value of each pixel in the compressed image and the corresponding approximate color related parameter are stored in pairs as a historical approximation processing result, and can be stored in a cache, so that the historical approximation processing result can be matched and called quickly to complete the color approximation processing.
In an optional embodiment of the present application, in S300, the preset code format includes an xterm code, and RGB values of approximate colors of each pixel in the compressed image after the color approximation processing are determined; converting the RGB value based on the approximate color of each pixel into an xterm code. Here, a preset code format, for example, xterm code, is determined based on a code format that can be directly read by the target terminal, and RGB values of each pixel approximate color in the compressed image after all color approximation processing are converted into xterm code one by one, for example, RGB values (255, 0, 0) are converted into \ e [ 38; 5; 9\ u2593 m. And directly reading and displaying the codes as red square shadows after the codes are obtained from the upper computer by using the ssh terminal.
Fig. 2 is a schematic flowchart illustrating a method for previewing a picture in a target terminal in an optional embodiment of the present application, where an application environment of the embodiment is to preview a picture in an upper computer by using an ssh terminal. Firstly, an upper computer is used for obtaining an image to be processed, and image compression processing is carried out on the image to be processed, for example, squares are used for replacing pixel points. Here, the pixel point is a single pixel, which is the smallest color unit on a computer, and each pixel has only one color. For example, if a picture is 400 × 600 in size, it is composed of 400 × 600 pixels. Each pixel is replaced by a square shadow. Under unicode encoding, there are some special characters, such as square shading, whose unicode encoding is \ u 2593. Although the square is text, it can be used as a pixel point, and a square shadow is used to replace the pixel.
Then, all pixels are traversed one by one, and the colors of all pixels are subjected to color approximation processing according to the RGB value of each pixel, so that 1600 ten thousand colors are approximated to 256 kinds in an xterm terminal. The bit depth of each pixel in a normal picture, i.e. the color type, is 256 × 256, about 1600 ten thousand. The xterm terminal can support 256 colors, although the number of the xterm terminal is different greatly, due to the limited resolution of human eyes, if the actual pixel color is converted into the most approximate xterm color, the compressed image after the color approximation processing can be distinguished by the human eyes and the actual application. Here, in the process of performing the color approximation processing, RGB values of 256 colors provided by xterm are acquired. And calculating the total difference value of three channels of the RGB value of the single pixel and the RGB value of each color in the 256 colors during the color approximation calculation, taking the total difference value as the weight, and taking the color corresponding to the minimum weight as the approximate color. If the actual color is (93,136,255), then (95,135,255) in xterm can be taken as the approximate color with the smallest weight, and the weight calculation process is (|93-95| + |136 | + |255 |) -255|) 3. For the color without calculated weight, all 256 colors are traversed, and the approximate color with the minimum weight is found and then paired to be stored in a cache as a history approximate processing result. And directly acquiring the approximate color from the buffer for the calculated color. And in the color matching of the toB side, the color is generally single and easy to distinguish after being approximated.
And finally, converting each approximate color into an xterm code, outputting the xterm code to an ssh terminal, and directly reading and displaying the preview picture. Therefore, the ssh remote terminal is directly used for previewing the pictures, and the pictures can be edited.
