Selecting the suitable stretch mode

A bitmap picture has got a fixed size. If the user needs to resize it, the program must apply a special algorithm that changes the size and even proportions of the original picture. This algorithm is called "stretch mode".

There are three different stretch modes. Each of them is suitable for different types of pictures and also for different type of output graphical device.

Considering the picture type, it is possible to give a simple clue as to which stretch mode should be applied to which picture type. Concerning the printing device, it is up to the user to find the most suitable stretch mode for his/her particular conditions.
