25. Create a grayscale image consisting of an 8×8 grid with a vertical
black line in the first column. Compress into JPEG format and
decompress. How far off are the resultant bytes at the default
quality setting? How would you describe the inaccuracies
introduced, visually? What quality setting is sufficient to recover
the file exactly?
26. Create an 8×8 grayscale image consisting of a 64-character ASCII
text string. Use lowercase letters only, with no whitespace or
punctuation. Compress into JPEG format and decompress. How
recognizable is the result, as text? Why might adding whitespace
make things worse?With the quality setting at 100, would this be a
plausible way of compressing text?
