This article only introduces the relevant content of JPEG compression. At the beginning, I tried to save time by using the features provided by Microsoft's GDI plus. It is very convenient to get the jpg image encoding first, create a bitmap object
The implementation steps are as follows:
1. Click the Browse button to select a jpg image file.Click the Browse button to open the file dialog box and select the jpg image file to get the path directory of the file.The key code is as follows:Char

The JPEG file format can be saved in two ways. They are Baseline JPEG and Progressive JPEG.
