What characteristics define a bitmap? Bitmap images are characterized by two parameters: the number of pixels (resolution) and the color depth per pixel. Color depth refers to the information contained within the image. For example, a 1-bit image means that a pixel could either be black or white.

Advantages of bitmap files include the following:

• Bitmap files may be easily created from existing pixel data stored in an array in memory.
• Retrieving pixel data stored in a bitmap file may often be accomplished by using a set of coordinates that allows the data to be conceptualized as a grid.

Bitmap, method by which a display space (such as a graphics image file) is defined, including the colour of each of its pixels (or bits). In effect, a bitmap is an array of binary data representing the values of pixels in an image or display. A GIF is an example of a graphics image file that has a bitmap.

Step 1: Multiply the detectors number of horizontal pixels by the number of vertical pixels to get the total number of pixels of the detector. Step 2: Multiply total number of pixels by the bit depth of the detector (16 bit, 14 bit etc.) to get the total number of bits of data.

TIFF is a lossless raster format that stands for Tagged Image File Format. Because of its extremely high quality, the format is primarily used in photography and desktop publishing. You’ll likely encounter TIFF files when you scan a document or take a photo with a professional digital camera.

The principal disadvantage of TIFF is file size. A single TIFF file can take up 100 megabytes (MB) or more of storage space — many times more than an equivalent JPEG file — so multiple TIFF images consume hard disk space very quickly.

TIFF files are much larger than JPEGs, but they’re also lossless. That means you lose no quality after saving and editing the file, no matter how many times you do it. This makes TIFF files perfect for images that require big editing jobs in Photoshop or other photo editing software.
