This is used to reduce the amount of storage used on a storage drive so that there is more space for other files. Compression is also used to make online uploads or downloads much faster. File type (e.g. JPEG, PNG), resolution (e.g. 1280 x 720) and colour depth (4 bit, 8 bit, 32 bit) can be changed to allow an image to be compressed and take up less storage space.
When you press "save as" on a piece of software like Photoshop, you can change the file type of the image. By changing the file type, you are also changing the quality of the image as different file types are compressed more than others. By saving an image as .JPEG, it is compressed using lossy compression. ]]> 2017-09-27 10:23:22 UTC https://padlet.com/wel17002232/ezrpp3pnle68/wish/191591456 wel17002232 https://padlet.com/wel17002232/ezrpp3pnle68/wish/191591511 Lossless compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data.

This is normally used for files such as audio and video as it isn't as noticeable, having an advantage as it allows reduction of file size with only a small decrease in quality.

In some instances, file sizes can be reduced by up to 60-70%. In addition,  a compressed file also moves more quickly over a computer network, whether this is the school LAN or the internet. Compression is also required sometimes when we want to send a file as an attachment through an email, sometimes the email may not send the file as the size is more than it takes. Therefore, you will need to compress the file so that the file size is small enough to send as an attachment through email. However, compression may lead to the loss of some data.

The reasons many use file compression is because it makes file backup more efficient, makes uploading files to a web page easier and lastly makes downloading and opening files from a web page easier as they are compressed]]> 2017-09-27 10:25:21 UTC https://padlet.com/wel17002232/ezrpp3pnle68/wish/191591913 LewisWh1te https://padlet.com/wel17002232/ezrpp3pnle68/wish/191603789 There are 2 types of compression. Lossy and Lossless. Compression can also lower the quality of your image making them more more pixelated and unclear. ]]> 2017-09-27 11:23:10 UTC https://padlet.com/wel17002232/ezrpp3pnle68/wish/191603789 str17002004 https://padlet.com/wel17002232/ezrpp3pnle68/wish/191604612 Lossless is a type of compression that allows the size of a file to be compressed while the quality of the file is not tampered in any way. This way of compression involves mainly around images, however can be used for other files such as mp3. As lossy permanently removes data during compression, lossless compressed data can be restored to its original format with nothing removed.]]> 2017-09-27 11:27:12 UTC https://padlet.com/wel17002232/ezrpp3pnle68/wish/191604612 samrokenson96961 https://padlet.com/wel17002232/ezrpp3pnle68/wish/191609732 - NOT made from a group of pixels, Instead they are joined by various paths which start from a beginning and end point. There are also various curves and angles throughout which combine to create the vector graphic.
-A Path can be different every time, sometimes it can be a shape or sometimes a Line, this tends to vary from vector to vector and can be used to make complexional diagrams and drawings.

However when a vector's image gets resized larger, the image's quality is still clear. This because vectors use mathematical equations when rendering the image instead of pixels. ]]> 2017-09-27 11:47:44 UTC https://padlet.com/wel17002232/ezrpp3pnle68/wish/191609982 str17002004 https://padlet.com/wel17002232/ezrpp3pnle68/wish/191611873

These graphics are related to the files such as .png,  .jpeg,  .gif and .bmp.  Generally these are not used for logos due to pixelation when scaling.]]> 2017-09-27 12:02:54 UTC https://padlet.com/wel17002232/ezrpp3pnle68/wish/191614489 wel17002232 https://padlet.com/wel17002232/ezrpp3pnle68/wish/194245838 2017-10-05 11:41:38 UTC https://padlet.com/wel17002232/ezrpp3pnle68/wish/194245838
