Is this way correct, pane?

No.
Doing it that way will fuck up the screenshot BADLY.

FIRST, set the image mode to 32-bit color (that's sometimes referred to as RGB or True Color)

IF the image is 320x240, resize the image to 640x480 with no interpolation.

ELSE
IF the image is 320x200, resize it to 640x400 with no interpolation.
THEN resize the image to 640x480 with linear interpolation.
