It compresses best when you can take advantage of the inter-line relationships. Things like the way that fax compression works. Compress the first line, then compress the changes between the first line and the second line, instead of compressing the second line all by itself. With certain types of images, there's even an advantage to compressing the color components separately from each other, i.e., split a line into a red line, a blue line, and a green line, and compress each separately, then do the "changes from previous line" thing as above.
