|Summary||0005949: failing example in comment of Form>>fadeImageCoarse:at: and Form>>fadeImageFine:at:|
example as in comment at the beginning of
It is not obvious to me how to make it work.
This happens in 3.7,3.8,3.9 at least.

Fix for mantis 0005949.
These two examples did not work if depth > 8. The problem was that the image and mask blocks were trying to store large intergers into the mask bitmap arrays. the solution was to mask out all the bits that didn't fit."
These are not called anywhere in 3.9 image. Where were they used originally?
(0009943 - 91 - 97 - 97 - 97 - 97 - 97)
Need to do a little more checking.
The fine fade needs some further tuning and debugging.
(0009944 - 858 - 984 - 984 - 984 - 984 - 984)
Which fixes things so that the transition and don't cause walk backs.
as I looked further into things, I discovered that all the methods with examples in this form catagory were designed to work at depths of 1 !
So their usefulness in present day squeak is questionable.
In short this is vestigial code and should be Removed or at least deprecated.
If something like this is needed then an update to 32 bits is needed.
Hint: The mask will have to be wider and will probably have to be aware of the depth.
Recommendation: Remove the old stuff.
Find out if someone has written an up to date equivalent.
If not find out if one is really needed.
Let the person who needs it make a case for its development.
I am choosing not to persue this any further.
Yours in service, --Jerome Peace
