Vector and Bitmap Graphics

BitMap Graphics

Are stored by individual pixels, remember the colour of every individual pixel

* Fixed Resolution, can't be changed on printers etc
* Remembers only the colour of pixel, no layers, objects, moving etc
* can edit individual pixels
* saves the whole screen of the image, even if blank


Vector Graphics

stored as a list of objects and their attributes - e.g. shape, x and y co-ordinates, line thickness, colour

* Resolution Independant, can vary to suit max available on printer
* can't edit individual pixels
* can build up layers of objects, greater flexibility
* can edit individual objects

Effects on Graphic Memory Requirements

adding more to an image???

Bitmap - none, already storing the colour of every pixel
Vector - increases, more objects to store requires more memory
