Update Icon.library 46.4.443
Download The improved "IconUpScaling" function creates now also smoother borders around the enlarged images besides the better image quality as done before already. Of course, it can never be as perfect as an image processing program will do it.
Please remember that the two optional scaling commands are not intended for permanent use. They should be activated on demand only. Then you could use CopyIcon to transfer the scaled images to all the destination icons and when this is done just call the same scaling command again to switch the scaling off.
Don't be surprised to see the "Format Change" requester also for the OS 3.5 icons since they are temporarily converted into the TrueColor format to allow the creation of new mixed colors for the additional inserted pixels.
After writing the scaled images to the target icons the images will appear scaled twice, which could be a bit confusing. But when you switch the scaling off as explained above, close the windows and open their drawers again then everything should look correctly
