The pictures on the gdi+drawimage will grow bigger.

Problem:

The pictures on the gdi+drawimage will grow bigger.

Explain:

Status DrawImage (Image *image,const point &point);
This interface of the two parameters is so designed, it means to paint according to the "physical size" of the photo, if the picture is 72dpi (ps default dpi, very common), and the Windows display is generally set to 96dpi, the actual pixel needs to be drawn more than the actual picture of the pixels, then the picture will be stretched

To display by pixel size, call the version of the 5 parameter
Status DrawImage (Image *image,
INT x,
INT y,
INT width,
INT height
);

The pictures on the gdi+drawimage will grow bigger.
