What information is stored in a PNG ?

(1). A PNG file stores pixel data in a binary format. This means that each color value (red, green, blue) is represented by a single bit. Each pixel can have any number of bits set to 1, depending on how bright the color should appear.

(2). The first four bytes store the width and height of the image. These are followed by the number of colors used in the image. Then comes the actual pixel values.

(3). The last two bytes contain metadata about the image. They include the compression method used to compress the image, whether the image was created using transparency, and if the alpha channel has been compressed.

(4). In addition to storing pixels, PNG files may also store other types of data. For example, they may store text strings, line art, or even images.

(3). PNG files are not self-contained. When you open them, you need to know where to find their contents. You do this by specifying a filename. If you don't specify a filename, then the program assumes that you want to save the file to your hard drive.
