When choosing a new camera, the most significant criteria an average user will consider will be the number of megapixels the camera is able to produce. On the one hand, they are right – pixels are tiny blocks that build the image, and a mega-pixel is a set of one million pixels. The more pixels the image contains, the more details the image will represent. Still, the whole situation with pixels and megapixels is not really truthful – unless the photo is printed on a really large paper, the difference between a 3 megapixel camera and one with 16 is not noticeable. When the image is to be printed, there are two factors to consider – PPI (pixels per inch) and DPI (dots per inch). PPI is a measurement of image resolution that defines the size an image will print. The higher the ppi value, the better quality print you will get. DPI is a measurement of printer resolution that defines how many dots of ink are placed on the page when the image is printed. ImageConverter Plus is able to adjust the dpi value of the digital images. It is possible to change the image resolution via the command line using the option “vdpi” (vertical DPI) and “hdpi” (horizontal DPI). An image with a lot of pixels is also called high resolution. An image with a low number of pixels is called low resolution. This is why the terms megapixels and resolution are sometimes used to mean the same thing.
