I had planned this as a useful exercise. However, it looks like the list based version doesn't have quite the behavior I expected.

As you may recall, one of the reasons we started to explore the vector-based implementation of palettes is that we expected the vector-based implementation to be significantly faster in reading pixel maps from files. (There shouldn't be much difference in saving pixel maps to files, but we should check that, too.) At the end of this lab you'll see some code to help you explore this question. You should have most of this code in the library, but it is included there in case you haven't written or you've neglected to save any of these key procedures. Here are a few list-based palettes of colors, randomly selected from the kitten image.

Here are some procedures that you may find useful as you do exercise 6. ; +------------------------+---------------------------------------------------- ; | Basic Input and Output | ; +------------------------+ ; +---------------+------------------------------------------------------------- ; | RGB Utilities | ; +---------------+ ; +-------------------+--------------------------------------------------------- ; | Palette Utilities | ; +-------------------+ ; +-------------------------+--------------------------------------------------- ; | Miscellaneous Utilities | ; +-------------------------+
