Shapes can be filled with solid colors, gradients, images, or even video.

Question 4

WPF animation

Answer 4

WPF has built-in support for animation. Animation refers to changing the display in small ways very quickly over time so that an object appears to move or change.

Question 5

WPF styles

Answer 5

A style is a named set of property settings. When you apply a style to an element, it sets that element’s properties to the values set in the style.

Question 6

WPF template

Answer 6

A template is similar to a style. A control template determines how a control is displayed. In WPF, however, the “look” of a control is not built into the operating system but is just a template that you can change.

Question 7

WPF dpi independence

Answer 7

• Instead of using the density of actual pixels to laying out the UI, WPF uses “deviceindependent pixels,” or dip.
• Each dip represents 1/96 of an inch—regardless of how many actual pixels that length corresponds to.
• If the user changes the dpi from 96 to 120—instead of the size changing, WPF can use the greater density of pixels to render greater detail
