Overview
The main function of the "changeBackground" app is to change or replace the background of the portrait. Firstly, extract the portrait from the original image (image matting); Then, select other images (image sources are divided into two types: one is to automatically crawl and select images from image websites that can be used as backgrounds, and the other is to select previously saved images from local computers that can be used as backgrounds) as replacement portrait backgrounds; Finally, overlay the portrait matting and background image and adjust them to save the composite image. The interface of the app has four preview frames, namely the original image ("Original"), portrait matting ("Portrait"), background image ("Background"), and composite image ("Composite"). In addition, when selecting the network background image, a thumbnail selection window will pop up and can be refreshed.
At the top of the interface are five buttons (two of which are radio buttons), which are briefly described from left to right as follows:
(1) Click the "Open Portrait" button, select the original image containing the portrait that you want to change the background on, and the original image will be displayed in the preview frame in the upper left corner. The cropped portrait will be displayed in the preview frame in the upper right corner. The image file extensions of the original image include *.png, *.jpg, *.jpeg, *.bmp, *.tif, *.tif, *.jfif, *.webp, and *.gif.
(2) Select the "Local Background" radio button, then click on the "Load Background" button on the right to select a new background image for replacement in the local computer, which will be displayed in the preview frame at the bottom left corner. The new background image and the extracted portrait image will be overlaid and displayed in the preview frame at the bottom right corner. The background image file extensions include *.png, *.jpg, *.jpeg, *.bmp, *.tif, *.tif, *.jfif, *.webp, and *.gif.
(3) Select the "Web Background" radio button, and then click on "Load Background" on the right. A new "Select Background" window will pop up, displaying 12 randomly loaded thumbnails from the image website. You can choose one thumbnail from them, and the original image corresponding to the selected thumbnail will be used as a replacement for the new background image, displayed in the preview frame in the lower left corner. The new background image and the extracted portrait image will be overlaid and displayed in the preview frame in the lower right corner. At the top of the "Select Background" pop-up window, there is a "Refresh Background" button, which randomly generates 12 new thumbnails in the pop-up window after each click.
(4) In the preview frame of the composite image in the lower right corner, you can drag the portrait matting with the left mouse button to move its position in the new background image. You can use the "Ctrl" key + mouse wheel to change the size of the portrait matting.
(5) Click "Save Composite" on the right, select a folder in the computer, enter the file name, and save the adjusted composite image in the preview frame at the bottom right as a png file.
