What is a Bitmap Image!

In computer graphics, a bitmap or pixmap is a type of memory organization or image file format used to store digital images. The term bitmap comes from the computer programming terminology, meaning just a map of bits, a spatially mapped array of bits. Now, along with pixmap, it commonly refers to the similar concept of a spatially mapped array of pixels. Raster images in general may be referred to as bitmaps or pixmaps, whether synthetic or photographic, in files or memory.

In certain contexts, the term bitmap implies one bit per pixel, while pixmap is used for images with multiple bits per pixel.

Many graphical user interfaces use bitmaps in their built-in graphics subsystems for example, the Microsoft Windows and OS/2 platforms' GDI subsystem, where the specific format used is the Windows and OS/2 bitmap file format, usually named with the file extension of .BMP. Besides BMP, other file formats that store literal bitmaps include InterLeaved Bitmap, Portable Bitmap, X Bitmap, and Wireless Application Protocol Bitmap. Similarly, most other image file formats, such as JPEG, TIFF, PNG, and GIF, also store bitmap images as opposed to vector graphics, but they are not usually referred to as bitmaps, since they use compressed formats internally.

What a Pixel is!

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. Each pixel has its own address. The address of a pixel corresponds to its coordinates. Pixels are normally arranged in a two-dimensional grid, and are often represented using dots or squares. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color image systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black.

In some contexts (such as descriptions of camera sensors), the term pixel is used to refer to a single scalar element of a multi-component representation chroma subsampling, the multi-component concept of a pixel can become difficult to apply, since the intensity measures for the different color components correspond to different spatial areas in a such a representation. while in others the term may refer to the entire set of such component intensities for a spatial position. In color systems that use

The word pixel is based on a contraction of pix.

 How i have used photoshop in my work is that i have used the brush tool mainly to manipulate where i want the light source to come from and where the shodow will be. I have you the warp tool as well to make the shadows appear bigger in certain place's.

Then too the paint tool i used this to make my creature be the colours that is. Then i used the flip tool to flip my one tree around so it was easy for me to use these tool's because of the shortcuts drew showed us.
