Binary images are also called bi-level or two-level. Pixel art made up of two colours is often referred to as 1-bit in reference to the single bit required to store each pixel. [2] The names black-and-white, B&W, monochrome or monochromatic are often used, but can also designate other image types with only one sample per pixel, such as ...
Grayscale images are distinct from one-bit bi-tonal black-and-white images, which, in the context of computer imaging, are images with only two colors: black and white (also called bilevel or binary images). Grayscale images have many shades of gray in between.
In mathematical morphology and digital image processing, a top-hat transform is an operation that extracts small elements and details from given images.There exist two types of top-hat transform: the white top-hat transform is defined as the difference between the input image and its opening by some structuring element, while the black top-hat transform is defined dually as the difference ...
Especially for small font sizes, rendering of vectorized fonts in "thumbnail" view can vary significantly with thumbnail size. Here, a small change in the upright= multiplier from 1.70 to 1.75 results in significant and mutually distinct rendering anomalies, possibly due to rounding errors resulting from use of integer font sizes.
When writing text to the screen, a BIOS color attribute is used to designate the color to write the text in. For example, to print a white character with a black background, a color attribute of 0F hex would be used. The high four bits are set to 0000 bin, representing the background color, black.

The edges of characters and other images with transparent background should not have shades of gray: these are normally used for intermediate colors between the color of the letter/image and that of the background, typically shades of gray being intermediate between a black letter and a white background. However, with, for example, a red ...
