WBMPcreator.WBMPfile#saveWBMP2File()

public WBMPfile rotate(int angle)

          Method to rotate a WBMP image. The result is also WBMP image with other dimensions: length of WBMP image turns into width and v.v. This is true for odd values of angle variable

Parameters:

angle - an integer representing quantity of Pi/2 rotations in positive direction (mathematicians will understand me :-|). I.e. if angle equals 0 then the image remains the same. If angle is even then dimensions also remain the same and if it is equal to n*4 where n is an integer then the picture returned is equal to current. Odd values of angle modify dimensions.

          Method to get a piece of an image.

Parameters:

area - a dimension
