So what is a pixel?
A pixel exists only at a point for a picture that is coloured the pixel could consist of three samples, one for each primary colour contributing to the picture that is being presented. We can not think a pixel as a square or anything other then a point. A pixel is basically a small point that is illuminating on a screen in a certain colour, there would be lots of pixels in a area to make a image. The smaller the pixels the better quality the picture is because there are lots more colours to make the image more detailed.
This image explains how a pixel works so as you can see there is on little pixel next to 1000+ more making up a image of a eagle.
Types of Digital Graphics
Raster Images - Raster Image is a image that changes to pixels when resized bigger, this is because it is unable to adjust the image to make it not change to pixels.
BMP: BMP is a type of file type image that is a Raster Image, it is also known as a bitmap image file or device independent bitmap (DIB) file format or simply a bitmap.
GIF: GIF is also known as Graphic Interchange Format, this is also a bitmap image format and it was developed by a US-based software writer Steve Wilhite.
TIFF: Tagged Image File Format, abbreviated as TIFF it is a computer file format for storing rater graphics images.
JPG: JPG is a file extension for a lossy graphics file. The JPEG file extension is used interchangeably with JPG. JPEG stands for Join Photographic Experts Group.
Vector Images - Is a image that when resized it does not go pixelated and instead the image re adjusts to make it not pixelated. Vector Images are a lot less common then Raster Images because they are a lot more advanced.
PSD: This is a Vector Image, a PSD file is a layered image file used in photoshop and it saves the images layer by layer instead of mashing them together to make one image because it does this it means that the person who saved it can go back and edit each layer of the image when ever they want.
WMF: Windows Metafile is an image file format originally designed for Microsoft Windows in the 1990's. Windows Metafiles are intended to be portable between applications and may contain both vector graphics and bitmap components.
FLA: The FLA file format is the master document format for flash projects. When you create a new Flash file in the Macromedia Flash authoring program, you create an FLA file.
AI: Adobe Illustrator Artwork is a proprietary file format developed by Adobe Systems for representing single-page vectore-based drawings in wither the EPS or PDF formats.
