file extension CD5

File extension CD5 description:

CD5 is Chasys Draw IES's native image file format, which supports all the features provided by the suite. It is a tag-based container format for images and animations. The current version is 3,05, and offers many enhancements over previous versions. Although CD5 is designed to be used as a working format (i.e. a format for storing work that is currently being edited or that may need to be modified later), it may be used for distribution because the policy is to support all versions of it in future versions. Common "lossy" formats such as JPEG may also be used where the recipient is not known to be using Chasys Draw IES.
