Graphics - graphic images Flashcards
bitmap
more common and easier to use in everyday functions
easily shared & is easier and more suitable for sharing completed final products
best for images because they support wide range of colour gradation
GIF, JPG, PNG, TIFF
professional and high quality
Images made with pixels of colour arranged across a grid
Bitmap images can handle complex colour gradients and are generally smaller in file size
they are susceptible to pixilation if the image is stretched beyond its original resolution
Suitable for photorealistic images
bitmap benefits
based on pixel patterns and can be edited by erasing or changing the colour of individual pixels,
most popular Web image format,
good for images that need wide range of colour gradation
bitmap limitations
aliasing: smooth curves and other lines become jagged because resolution of the graphics device/file is not high enough, blurry when scaled up, resolution dependent
o E.g. Microsoft paint
vector
Images that are made with mathematical algorithms and therefore, able to be enlarged to any size without pixilation.
unable to handle complex colour gradations/photorealism without having a large unmanageable file size.
suitable for simple illustrations with little tonal variation
equations adjust based on the scaling of the image
high scalability
more specialised files, appear in less common formats such as AI and Windows Metafile
good for logos because it is small in size and can be dramatically resized in order to fit into very small (stickers, labels) or very large surfaces (billboard)
less variations
vector benefits
can be smaller because uses mathematical formulas instead of pixel patterns, which takes up less space,
more scalable
render at highest quality because they are device Independent, individual, scalable objects
vector limitations
unsuitable for photo-realistic imagery, vectors used for more simple images, unsuitable for more complex images
o e.g. illustrator
