What I’m going to talk about:• Important formats • Mixmag project
What are raster graphics?
Raster files can consist of on an image or bitmap that has a dox matrix data structure generally representing a grid of pixels or points of colour.
Types of Raster formats Images –Jpegs/TIFF/RAW/GIF/BMP/ PNG/PPM/ PGM/PBM/PNM/WEBP/
Software -Adobe Photoshop,ArcSoft PhotoImpression,Corel AfterShot Pro and Microsoft Paint etc
Evidence where I have used this
• Jpegs easy manipulate• Create effective themes
ADVANTAGES
• Distortion
DISADVANTAGES
What are vector graphics?
Vector graphics are mathematic equations that are used to represent images in computer graphics through the lines and shapes being created to form the image part of the structure i.e. the colour, a shape, a thickness of the image. This is ideal for printing magazines
Types of vector software
• Inkscape• CorelDRAW• Adobe Fireworks/ Adobe illustrator
Example of where I have used this:• is?:
• Record label• Cd t• photoshop
• Thin lines may disappear if a vector drawing is reduced too much.
• Small errors in a drawing may become visible as soon as it is enlarged too much
Disadvantages
Metafiles application
Metafiles graphics consist of more than one type of a format which can store a multiple of data i.e Raster and Vector graphics.
What are Metafiles?
Examples of metafiles software:• WMF (Windows Metafile) • EMF (Enhanced Metafile)• CGM (Computer Graphics Metafile).• (CDR) Corel Draw File• photoshop
