An image size can be changed in several ways. Consider resizing a 160x160 pixel photo to the following 40x40 pixel thumbnail and then scaling the thumbnail to a 160x160 pixel image. Also consider doubling the size of the following image containing text.
In some systems, as Hercules and CGA graphic cards for the IBM PC, a bit value of 1 represents white pixels (light on) and a value of 0 the black ones (light off); others, like the Atari ST and Apple Macintosh with monochrome monitors, a bit value of 0 means a white pixel (no ink) and a value of 1 means a black pixel (dot of ink), which it ...
The 4-bit per pixel (4bpp) format supports 16 distinct colors and stores 2 pixels per 1 byte, the left-most pixel being in the more significant nibble. [5] Each pixel value is a 4-bit index into a table of up to 16 colors. The 8-bit per pixel (8bpp) format supports 256 distinct colors and stores 1 pixel per 1 byte.
In comparison to the raw pixel information captured by the image sensor, the output pixels could be formatted differently based on the active pixel format. For several digital cameras, this format is a user-configurable feature; the available pixel formats on a particular camera depends on the type and model of the camera. [1] [2]
Thus unambiguous strings of nine characters could set the color of each pixel by its XPM palette index with up to 10 9 = 1 000 000 000 colors (compare to GIF, which supports only 256). For XPM2 it is clear how many lines belong to the image – two header lines, the second header line announcing the number of color codes (2 lines in the example ...
The P4 binary format of the same image represents each pixel with a single bit. A row is width pixels wide packed to the length of 8 pixels or a byte. The first pixel in a row is the most significant bit. The extra bits used to make the length equal to a byte are ignored.

In computer graphics, planar is the method of arranging pixel data into several bitplanes of RAM.Each bit in a bitplane is related to one pixel on the screen. Unlike packed, high color, or true color graphics, the whole dataset for an individual pixel is not in one specific location in RAM, but spread across the bitplanes that make up the display.
