You are changing the values of one or more pixels.
Raster images are composed of pixels, editing them means changing the values of some pixels.
Yes, another word for a picture element is "pixel." A pixel is the smallest unit of a digital image or display, representing a single point in a raster image. It is the building block of images in digital formats, contributing to the overall resolution and detail.
Raster scan, or raster scanning: is the pattern of image detection and reconstruction in television, and is the pattern of image storage and transmission used in most computer image systems. The word raster comes from the Latin word for a rake, as the pattern left by a rake resembles the parallel lines of a scanning raster. Picture element: In a raster scan, an image is cut up into successive samples called pixels, or picture elements, along scan lines. Each scan line can be transmitted as it is read from the detector, as in television systems, or can be stored as a row of pixel values in an array in a computer system. On a television receiver or computer monitor, the scan line is turned back to a line across an image, in the same order. After each scan line, the position of the scan line is advanced, typically downward across the image in a process known as vertical scanning, and a next scan line is detected, transmitted, stored, retrieved, or displayed. This ordering of pixels by rows is known as raster order, or raster scan order.
Raster IS a type of image data another type is VECTOR.Raster deals with picture elements (pixels) these are discrete bits of the picture , small dots or swuares that together make up the entire image).Vectors deal with mathematical expressions for lines and areas. You can zoom in invinitely into a vector image and neve get blocks or jaggged edges which appear in raster images.
Raster printing refers to the method of printing which uses the raster image processor. The raster printing usually produces a raster image called a bitmap.
In digital imaging, a pixel is a single point in a raster image, or the smallest addressable screen element in a display device; it is the smallest unit of picture that can be represented or controlled

A raster image is made up of individual pixels (picture elements) often these are square.

A bitmap graphic is also known as a raster image.
It is a "picture element" which is a single dot of color in an image.
