The height of the BMP image must be twice the height declared in the image directory. This is because the actual image data will contain two parts: the actual image immediately followed by a 1 bit mask of the same size as the image used to determine which pixels will be drawn. The mask has to align to a DWORD (32 bits) and should be packed with 0s.
Image scaling can be interpreted as a form of image resampling or image reconstruction from the view of the Nyquist sampling theorem. According to the theorem, downsampling to a smaller image from a higher-resolution original can only be carried out after applying a suitable 2D anti-aliasing filter to prevent aliasing artifacts. The image is ...
For practical purposes the clarity of the image is decided by its spatial resolution, not the number of pixels in an image. In effect, spatial resolution is the number of independent pixel values per unit length. The spatial resolution of consumer displays ranges from 50 to 800 pixel lines per inch.
