- The whole VALUE of an image is based on at least 3 values
Width x Height x Resolution (or PPI/PDI)
- ..then *if* you want to step further to take about SIZE then the SIZE
will
be based on 4 values
Width x Height x Resolution x COMPRESSION
- .. and *if* you want to go another step further by asking why some
program
gives smaller/LARGER size using the same value. In this case then we can
say the whole VALUE is based on 5 different values
Width x Height x Resolution x Compression x HEADER INFORMATION
