What does 'skew' refer to in graphic transformations?

In the context of graphic transformations, 'skew' refers to a method of distorting an image by slanting it along the X or Y axis. This transformation alters the shape of the object, resulting in a perspective shift that can make it appear slanted or tilted rather than changing its size or breaking it apart like other transformations might. Skewing can be particularly useful in design and graphics, as it allows for the creation of dynamic visuals that can enhance a layout or convey a sense of motion.

Other options refer to different concepts that are not related to the specific transformation known as skew. Color adjustments focus on altering the hue, saturation, or brightness of images; layering objects is about arranging different graphical elements on top of one another; and sound enhancement pertains to audio processing, which is a separate discipline altogether. Thus, the notion of skew as a distortion method clearly distinguishes it from these other functions in graphic design and multimedia practices.
