How to change and reduce the resolution of image scanning in CorelDRAW

Q: How do I reduce the scanning resolution in CorelDRAW?

I would like to ask you, I do some of the ads are particularly large, how to change the small?

Some of the pictures are scanned from the scanner, the DPI is very large, if you want to change the DPI after scanning how to change the small? is the DPI leading to large capacity?

A: This does not fit, the larger the scanning resolution, the larger the file. While scanning the picture, the larger the resolution, the clearer the image is, but it is not absolute, it depends on your needs. You check to try to sweep a picture to see, 10CM below the size of 300 dip and 1200 dpi look at the difference.

Generally speaking, the resolution 200-300 is enough to be put on the net, to be used for printing, between 400-1200. Advertising, you can calculate the size of your picture and the actual size of the magnification, and then calculate the actual size of the required resolution, you will know what kind of resolution to do the map. In addition, in the PS can directly change the image resolution, in the Image menu image size change. Advertising also pay attention to: if it is printed, resolution more than 300, inkjet: 35DIP enough, pictorial words general, 72DIP, or at most 96DIP, or you do 1:1 of the figure, with 150DIP output, do a 10-meter inkjet file size enough to eat your entire hard drive, not scared to death you are strange.
