StuffIt SDK

Additional Format Support

StuffIt X Duplicate Folding™ feature

The StuffIt Engine SDK is a cross-platform suite of APIs allowing a client to access the StuffIt Engine for basic compression and expansion as well as more advanced tasks such as manipulation of an archive's contents.

In order for the SDK to be cross platform, certain data types and object representations needed to be abstracted. String and references to file system objects need to be converted from their platform specific types to their respective StuffIt SDK types.

Strings

StringRef is the data type used to expose string functionality in the SDK. A StringRef can be created in a number of ways depending on the platform. For instance, a C string or Pascal string may be used to create a StringRef on Windows or Mac OS X, but only the Mac supports creating a StringRef from the native CFString object.

File System Objects

An FSObjectRef is the sole way of providing objects to the SDK that represent an item within the file system. Similar to StringRefs, creation of an FSObjectRef varies by platform.

Notifications

The SDK uses notifications so that the client can provide it's own progress user interface as well as other interactions that might require user feedback.

Updates from previous version.

Version 12 of the StuffIt SDK added specific file formats compressors were added to sitx format to support the following file types: jpeg, mp3, bmp, gif, png, tiff, pdf, psd, jpeg2k, jpeg lossless, pict, ptt5 and pxm.

Version 12 also added zip content recompression option to sitx format. This allows to recompress zip archives content when being added to sitx archive that results in better compression ratio. The zip archive is reconstructed on expansion.

The SDK kit, sdk-13.0.0.*-win32-msvc9-release.zip kit was built with MS Visual C++ 2008 - Microsoft Visual Studio 2008 Version 9.0
