When multimedia developers produce Bitmapped Images, they must consider that a bitmapped image is device-dependent. For that reason, they often need to produce multiple bitmapped images that have different spatial resolutions based on their intended use. For example, they produce a bitmapped image to be printed, and reduce its spatial resolution to be displayed on monitors.

What does it mean to say that a bitmapped image is device-dependent? Explain why different resolutions of bitmapped images are needed for different devices such as monitors and printers.

Answer 1

Whenenver it is said that a bitmap image is device dependent then it means that an image stored in a format which is called as hardware proprietary format.

The device dependent bitmapped images are dependent upon the storage format of a particular device in which the bitmap of the image will be sent to the screen for displaying.

The different resolutions of bitmapped images are required because of the densities.

The bitmap images are supposed to be appear the same on different devices having dfferent resolutions and different resolutions means that devices have different screen densities.

The bitmap image will look much sharper on different devices with different densities of screen.

Also this will make sure that the CPU will work effectually on the different devices.
