If you have used image editing and manipulation in delphi, there is a good change you have used or heard of ImageEn components. I have used them in my photo printing program, Pics Print.
The ImageEn component suite has now moved to delphi shareware company Xequte. You can find them at www.xequte.com/imageen or at www.imageen.com. If you want to see the components in action, download demos from here.
