What is bitmapped image why it is so called?
A bitmap is a type of memory organization or image file format used to store digital images. The term bitmap comes from the computer programming terminology, meaning just a map of bits, a spatially mapped array of bits.
What are the 2 different types of images?
All digital image files fall into one of two categories: vector or raster. Each format has advantages and disadvantages in different situations, so knowing the properties of each can help determine which format is the best choice for any project.

What are screen pixels?
Pixels, or picture elements, are the smallest physical points on a display, as well as the base components. Pixels are therefore the building blocks of any image you see on your screen. Pixels and resolution are directly correlated and a higher resolution equals a higher number of pixels on a monitor screen.

What is the full form of DPI?

How are colors represented in pixels?
The number of bits used to represent the colours of pixels in a particular image is sometimes referred to as its “colour depth” or “bit depth”. For example, an image or display with a colour depth of 8-bits has a choice of 256 colours for each pixel.
What shape is a pixel?
Pixels on computer monitors are normally “square” (that is, have equal horizontal and vertical sampling pitch); pixels in other systems are often “rectangular” (that is, have unequal horizontal and vertical sampling pitch – oblong in shape), as are digital video formats with diverse aspect ratios, such as the …
What information is stored in a pixel?
color information
Is pixel a circle or square?
Pixels are commonly square because squares fit together without leaving gaps, have sides of equal length and can be mapped to a grid with two axes – horizontal and vertical. If pixels were circles, there would be gaps when surrounded by neighbouring circles – not ideal for creating smooth images on a screen.
Do pixels have to be square?
In digital imaging, a pixel, pel, or picture element is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen. A pixel does not need to be rendered as a small square.
Can a pixel be rectangle?
I have a circle image, but I am using it on android devices on some devices its not perfectly circle. I have one doubt a pixel is a square always or can be rectangle, depending on device. If so how to handle this since circle image has same number of pixel in width and height.
