we want to retrieve TIFF images from IBM FileNet CMS on safari browser on ipad and editing (annotate) them and get it back to FileNet. We found a SDK called snowbound which
is providing web document viewing & manipulation solutions specially documents from FileNet, but the support provided by them is not enough probably cause the solution is not free

so please help me to find some well supported solution (will be better if it also free)
