Bitmap

[Wessner54]

A bitmap is a file that indicates a color for each pixel along the horizontal axis or row (called the x coordinate) and a color for each pixel along the vertical axis (called the y coordinate). A Graphics Interchange Format file, for example, contains a bitmap of an image (along with other Link removed Web Design Company data).

Screen image sharpness is sometimes expressed as dots per inch (dots per inch). (In this usage, the term dot means pixel, not dot as in dot pitch.) Dots per inch are determined by both the physical screen size and the resolution setting. A given image will have lower resolution fewer dots per inch on a larger screen as the same data is spread out over a larger physical area.

On the same size screen, the image will have lower resolution if the resolution setting is made lower resetting from 800 by 600 pixels per horizontal and vertical line to 640 by 480 means fewer dots per inch on the screen and an image that is less sharp. (On the other hand, individual image elements such as text will be larger in size.)

An interlaced display is a cathode-ray tube (CRT) display in which the lines are scanned alternately in two interwoven rasterizes lines.

A non-interlaced display is a cathode-ray tube (CRT) display in which the lines are scanned sequentially from the top to the bottom of the screen.

lol yeah right?

In typical uncompressed bitmaps, image pixels are generally stored with a color depth of 1, 4, 8, 16, 24, 32, 48, or 64 bits per pixel. Pixels of 8 bits and fewer can represent either grayscale or indexed color. An alpha channel (for transparency) may be stored in a separate bitmap, where it is similar to a greyscale bitmap, or in a fourth channel that, for example, converts 24-bit images to 32 bits per pixel.

That was a very good information to know about bitmap. It is always nice to read and know knew knowledge. Thank you for sharing it

Bitmap images are a collection of individually colored, minute dots or pixels that are arrayed in a matrix or grid.The quality of a bitmap image depends mainly on its resolution. Therefore, resizing bitmap images result in poorer image quality.

Why don't we just go to the dictionary and start with the A's. We'll just post definitions. Very creative.
