Dpi resolution(dots per inch)=Dots per inch (DPI) is a measure of spatial priniting or video dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm).
quality(of an image)= the standard of something as measured against other things of a similar kind; the degree of excellence of something.
Compression settings=Compression is the process of lessening the dynamic range between the loudest and quietest parts of an audio signal.
Bitmap/raster=when you take a photograph using a digital camera or scan an image from a magazine, you are creating a bitmap graphic.
Vector= Vector graphics are created in graphics packages and consist of shapes called objects.
What are the differences= the differences between Vector and Bitamp is that bitmap graphics are made up of pixels of differenct colours where as vetors are made up of objects.Also Bimap can be edited by individaul pixels and vector grahics can be edited by individual objects and when they are resized Bitmap lose quality well as Vector graphics do not loose their quality.Another thing is that Bitmap graphics look real well as Vector graphics do not look that real they look more like cartoon images.and finally there common formats are different the bitmap files common are .bmp, .dib, jpeg, gif, tiff, .png well as the Vector Graphics formats are.cgm, .svg, .odg, .eps, .xml.
what are thease different file types?
.tiff=tiff stands for "Tagged Image File Format" and is a standard in the printing and publishing industry. tiff files are much more larger than theirjpeg counterparts and they can can be either uncompressed or compressed using lossless compression. A advanage of this file is that tiff files can have a bit depth of either 16-bits per channel or 8-bits per channel, and multiple layered images can be stored in a single tiff file. Another benefit of this file type is that the tiff files are very good for archiving intermediate files which you may edit later, since it introduces no compression artifacts.also many cameras have an option to create images as Tiff files which is good.
.jpg=JPEG stands for Joint Photographic Expert Group" this was specifically developed for storing photographic images which is very uselfu but it has also become a standard format for storing images in digital cameras and displaying photographic images on internet web pages which is a benefit as you can store many images in your digital camera JPEG files are much smaller than those saved as TIFF, however this comes at a cost since JPEG.Another benefit of this is that it is also helpful to get a visual intuition for how varying degrees of compression impact the quality of your image. At 100%, you will barely notice any difference between the compressed and uncompressed.
.png= Png stands for Portable Network Graphics which is a raster graphic file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format, and is the most used lossless image compression format on the Internet.
