ntegers: the first is the number of pixel columns or width and the second is the number of pixel rows or height. Another common way to express resolution is by giving the total number of pixels in the image (usually expressed as megapixels). It is determined by simply multiplying the pixel columns by the pixel rows.Most typical file formats such as bmp, jpeg, png [link widoczny dla zalogowanych], etc. will give the physical image size. This is done through DPI. For raster images (those images in rectangular pixel format), DPI means the number of pixels printed within one inch horizontally and vertically. For example, if you have an image expressed at 600 by 300 (or 1.8 megapixels) and you want to print at 300 dpi, the image would need to be printed within two inches by 1 inch (you divide 600 x 300 by 300 dpi) – a very small image to get the needed resolution. The bigger you print the same image [link widoczny dla zalogowanych], obviously, the lower the amount of dots per inch. A 20 by 10 inch print of the same image would be only 30 dpi. Try to imagine how bad the quality would be if you had only 30 dots for every inch.We commonly have customers uploading 600 x 300 jpeg images of the family dog, say [link widoczny dla zalogowanych], and ask us to put it on a vinyl banner 4 by 2 feet, for example. We refuse to print a sign with less than 300 dpi, because we know our cus
