Upgrading from Previous versions of ImageMan DLL Suite

Although maintaining backward compatibility is very important to us, in Version 8 we have made some breaking changes to the functions dealing with Option Blocks. These changes were implemented so we could add support for getting image attributes from opened images. Doing this required us to add type information for each option block setting and therefore the ImgXOptBlkAdd and ImgXOptBlkGet functions now take and return a flags value which indicates the datatype of the value.

Changed - The ImgXOptBlkCreate no longer takes a param. It just returns handle to an empty option block. Code will need to be modified to call ImgXOptBlkAdd to add any settings which were being passed to the ImgXOptBlkCreate call.
Changed - ImgXOptBlkAdd now takes parameters. Existing code will need to be modified pass the additional parameters.
Added - The ImgMergeImage function allows combining images with optional transparency. Also allows manipulation of the color channels.
Added - The ImgOptionNames function is used to get the names of attributes from an opened image.
Added - The ImgOptionValue function is used to retrieve the value of an attribute from an opened image.
