推荐答案

不清楚您要做什么，这是您要查找的内容:

Not too clear on what you are trying to do, is this what you are looking for: Convert jpeg image to Byte array[^]

you can use Windows GDI and GDI+ functions to get bytes from every pixel of a JPEG image.

1.create a bitmap by loading your jpeg image.
2.retrieve bits using getbitmapbits() or getDIBits() windows GDI functions

Link Windows GDI:
