7 PS can process pictures, make pictures

Create a new canvas and finally a picture

8 The smallest unit of a picture's composition is the pixel

9 resolution is the number of pixels on the unit area .

Equal unit area, the higher the pixel, the higher the picture quality, the more fine

That is, if the same large display, if its resolution higher, give people feel more comfortable

10-bit graph:

The constituent unit is a pixel "a small dot with color values, a point with only one color value"

One vector diagram:

Bitmaps are composed of dots, each of which contains information such as color, lightness, and so on. Bitmaps can represent fine images, so graphic files such as art pictures, photos, etc. are in bitmap format. The disadvantage of bitmaps is that the image file is large, if the original bitmap information is limited (few points), it can not be arbitrarily magnified.
