GDI+ drawing in 200% DPI (192 pixel), will come to incorrect background.
In this case, the dialog is bigger than my screen. The right part of the dialog can not display when the app starts up. when I drag the dialog to the center of the screen, and see that the right part of the background image is the center part of the dialog's parent window's background image. I make the dialog to repaint, it can get the right image.
I works well in 125%, 150% DPI. How can I fix the problem to draw a right image in 200% DPI?
Can anyone help? Thanks
