  2. 2. BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – Raster ImagesRaster images or bitmaps are a data structure representing a generally rectangular gridof pixels or points of colour, viewable via a monitor, paper, or other display medium. The image on the left is a raster image as it looks pixelated but when it is looked at from far enough away it doesn’t look as rectangular or pixelated. A bitmap corresponds bit-for-bit with an image displayed on a screen, generally in the same format used for storage in the displays video memory, or maybe as a device-independent bitmap.
  3. 3. BTec Level 3Extended Diploma in Creative Media ProductionVector Images Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based on mathematical equations, to represent images in computer graphics. One advantage of using vector graphics is that you can scale them as long as the aspect ratio is maintained without pixilation becoming a factor. However even though vector images are so high quality they are not very good when using realistic images. Because vector images are such high quality they can only Be saved in certain formats such as EPS, PDF & PICT.
  4. 4. BTec Level 3Extended Diploma in Creative Media ProductionAntialiasingAnti-aliasing is the technique of minimizing the distortion artefacts known as aliasingwhen representing a high-resolution image at a lower resolution. Anti-aliasing is usedin digital photography, computer graphics, digital audio, and many other applications.The images below are without Antialiasing as the edges are jagged and pixelatedThe images below have been rendered with Antialiasing as they have smooth edges.By Antialiasing the eye has been tricked into thinking this, but if you zoom in like thePicture on the right you can see that Antialiasing has just neatened the pixelated edges.
  5. 5. BTec Level 3Extended Diploma in Creative Media ProductionResolution This would be an example as a high resolution as it will Have more pixels per inch more than the average picture. This would be an example of a low quality resolution as there Will not be as many pixels per inch in this image.
