Take our 100 x 100 pixel image again. Suppose it's set at 100 PPI (producing the same 1 x 1 printed image). With re-sampling off, when you adjust the PPI the dimensions adjust as well, this is how things worked in the example above. With re-sampling on, the dimensions won't change.
Leftover charcoal ash can be used to help increase the pH levels in your yard. Rather than use lime and potash as a fertilizing material, collect ash in a metal bucket over the course of a grilling season and then spread the ash on your yard in an amount of no more than 10 to 15 pounds per 1,000 square feet.
When you have a bag of used charcoal (and not briquettes with additives) sitting around your garage, there are a number of ways to use it up, even if grilling isn't on this Summer's agenda. 1  Keep a few pieces in a perforated plastic bag in the refrigerator to kill odors. 2  Feed your compost pile to increase the carbon content.
