Images
Image file formats:
JPEG (Joint Photographic Experts Group) - used for mainly photographs and images to be used on the web due to them being smaller in size
GIF (Graphics Interchange Format) - can only exist in 256 colour mode, they are basic and appropriate for the web but not for high-quality print graphics
PNG (Portable Network Graphics) - is a highly compressed format that can replace GIF and JPEG images for the web
PICT - Apple standard graphic, not supported in all graphics programs, can be a bitmap or vector graphic
PDF (Portable Document Format) - can contain bitmap images, vector images, text, etc, is compressed and an easily viewable format, can be protected so that it cannot be edited
PSD (Photoshop Document) - unable to view this file unless using the Creative Suite, can be a very large file size, need to resave images from this format to be used elsewhere
TIFF (Tagged Image File Format) - lossless image, not supported in all graphics programs (Apple), they can be grayscale, and have a large file size
Vector images:
Made up of many individual, scalable objects
Defined by mathematical equations rather than pixels, so they always render at the highest quality
Objects may consist of lines, curves, and shapes with editable attributes eg. color
-
-
Size of the file is directly proportional to the number of objects it contains, could be a big or small size
Bitmap images:
-
When editing a bitmap, you are editing the colour values of individual pixels
Large file sizes, because Bitmaps are lossless
