A monochrome bitmap is a digital image that displays only one color, usually black. It is created using a bitmap file format and has pixels that are only one bit, allowing each pixel to display only one color or no color. Monochrome bitmaps have only two colors available, usually black and white. Each bit used to create a monochrome bitmap is binary information, represented by either ones or zeros.
A monochrome bitmap is a type of digital image that displays a single color, usually black. This is a type of a particular file format, referred to as a bitmap (BMP), and is often used in creating simple graphics. In a bitmap, each pixel or “picture element” of an image is represented by a particular number of bits, which are units of information. A monochrome bitmap has pixels that are only one bit, allowing each pixel to display only one color or no color, often seen as black and white.
There are several reasons why someone might create a monochrome bitmap, although these images are all created using the same data type. Most users of digital art programs don’t necessarily interact with individual bits of data in their creations, but instead adjust settings in the software that affect how those bits are used. A bitmap, which is a commonly used file format for digital images, is simply a type of image based on pixels. Pixels are individual components of an image, usually seen as tiny dots of pigment or light, similar to the dots of color used in creating a painting through pointillism.
A bitmap image, such as a monochrome bitmap, is created in a way that assigns a different number of data bits to each pixel in the image; this is referred to as “bits per pixel” (BPP). The number of colors that can be displayed on a bitmap image is two to the power of the BPP number for that particular file. An image that can be displayed in “256 colors,” meaning that up to 256 different colors can be used, is an 8-bit image; eight bits are used to determine the color of each pixel, meaning there are 28 or 256 colors available.
Only one bit of data is used for each pixel of a monochrome bitmap, meaning these images are only 1 BPP. This means that such images can have 21 colors or only two colors available. While it is technically possible to set these colors differently, typically a monochrome bitmap is created with one color black and the other transparent. Because this transparent area usually appears on computer screens and paper as white, these images are considered black and white.
Each bit used to create a monochrome bitmap is binary information, meaning it is represented by either ones or zeros. A pixel with a value of zero usually appears as transparent or white, while pixels with a value of one are black. These images don’t have the option of other colors or values, so a monochrome bitmap displays sharp, straight horizontal and vertical lines, but curved and diagonal lines can appear more jagged.
