Our friend Hermitian made a somewhat puzzling suggestion when I pointed out to him that the Whitehouse PDF had been significantly compressed.
First of all he failed to understand that the 150 DPI resolution for the background was only part of the loss in quality of the background, after all, the JPEG compression itself had reduced the size of the image significantly but at the expense of about 50% of the quality.
Then he suggested that I should print out the document at 600 or 1200 DPI…
Does he not understand that such a picture will not truly be 600 or 1200 DPI? Anything above 150 DPI will be interpolated and this will result in a softening and blurring of the image. Anyone familiar with information theory would know that you cannot recreate lost information by just blowing up the resolution.
It’s quite fun to help Hermitian understand these basic principles of image analysis.
