Pixels, a point resolution, length per inch, number of pixels, abbreviated DPI, usually 300dpi picture size, picture width, number of pixels and resolution of images available, image width (cm cm) = image width pixels/resolution, high = image high pixel/resolution, You can set the DPI when printing, the size of the picture will change, the specific size can be calculated from the above formula. For example, the number of pixels is unchanged, the resolution increases, the print size decreases, the pixels decrease, the resolution is constant, the print size decreases the size of the other picture, that is, the picture takes up hard disk capacity, with more pixel count, lower compression ratio, higher compression quality, larger size. If the number of pixels is constant, reducing the compression ratio, the file size increases
Pixel, resolution, picture size
