If we want the left image to become the right image, we can use the techniques from above to achieve the requirement. There are several ways to solve this problem, this is one of the possible solutions. First, we apply clockwise rotation of 90 degree by using one of the transform. STFT:
An anti-aliased image may use more colours than you notice, because anti-aliasing smooths jagged edges by adding shades of grey where once there was black or white. Anti-aliased black-and-white images usually need to be saved as 16-colour or 256-colour images instead. See the illustration at the right.

For all these systems both photon world lines represent the angle bisectors of the axes. The more the relative speed approaches the speed of light the more the axes approach the corresponding angle bisector. The axis is always more flat and the time axis more steep than the photon world lines. The scales on both axes are always identical, but ...
The angle θ and axis unit vector e define a rotation, concisely represented by the rotation vector θe.. In mathematics, the axis–angle representation parameterizes a rotation in a three-dimensional Euclidean space by two quantities: a unit vector e indicating the direction of an axis of rotation, and an angle of rotation θ describing the magnitude and sense (e.g., clockwise) of the ...
The image quality has been lost. No quality is lost however, with the lens zoomed-in optically for the bottom photo. Typically, the digital zoom is not available until the optical zoom has been exhausted. Digital zoom is a method of decreasing the precise angle of view of a digital photograph or video image.
An image histogram is a type of histogram that acts as a graphical representation of the tonal distribution in a digital image. [1] It plots the number of pixels for each tonal value. By looking at the histogram for a specific image a viewer will be able to judge the entire tonal distribution at a glance.
