Compressonator is a set of tools to allow artists and developers to more easily create compressed texture image assets and easily visualize the quality impact of various compression technologies. It consists of a GUI application, a command line application and an SDK for easy integration into a developer tool chain.

Compressonator DXTn (S3TC)is developed for Microsoft Windows® platform.

Mainline Branch

Added GPU based compressed image views using OpenGL, DirectX 11 and Vulkan

V2.3 Branch Installer for prebuilt SDK Libs, GUI and Command line application

Support for ASTC and ETC2

Variable sized compression buffers

To build the applications you will need to have Visual Studio 2015 installed.

The directory of your workspace should be as follows

• Common
• Compressonator
• LICENSE
• README.md

It is also recommended that you install and configure Visual Studio Qt5 Package extension from MSDN Visual Studio Gallery, and set in Qt Options dialog, Qt Default Version name V5.5 and path to Common\Lib\Ext\Qt\5.5\bin

https://visualstudiogallery.msdn.microsoft.com/c89ff880-8509-47a4-a262-e4fa07168408

Simply run one of the batch files from a window console.

To build the Compressonator GUI run BuildGUI To build the Compressonator Command line Tool run BuildCLI

Go to the associated directory where Visual Studio Solution Files are located as indicated in steps A through C.

All of the Applications (B, C) apart from the SDK libs (A) can be built as either Release_MD or Debug_MD 32 Bit applications.

For Application builds make sure that the default startup projects are set as follows:

(B) CommandLine solution set to CompressonatorCLI (C) GUI solution set to MainApp

Always clean and rebuild the projects

\Compressonator\VS2015\CompressonatorLib.sln

This solution will create a build folder that contains DLL and Libs under \Compressonator\Build\VS2015(configuration)(platform)\

example: Compressonator\Build\VS2015\Release_MD\Win32\

\Compressonator\Applications\CompressonatorCLI\VS2015\VS2015.sln

This solution will create a build folder that contains a CompressonatorCLI.exe and a new plugins folder under \Compressonator\Build\VS2015(configuration)(platform)\

The command line tool has dependencies on Qt (V5.4 and up)

• icuin54.dll
• icuuc54.dll
• icudt54.dll
• Qt5Core.dll
• Qt5Gui.dll
• libGLESv2.dll
• opencv_core249.dll
• opencv_imgproc249.dll
• opencv_highgui249.dll
• glew32.dll
• vulkan-1.dll

The dlls above are copied from common to CompressonatorCLI.exe folder by building the "CopyScript" project in the VS2015.sln.

\Compressonator\Applications\CompressonatorGUI\VS2015\VS2015.sln

This solution will create a build folder that contains a Compressonator.exe and a plugins folder under \Compressonator\Build\VS2015(configuration)(platform)\

If building in Debug_MD configuration, please make sure the working directory is in \Compressonator\Build\VS2015\Debug_MD(platform)\

The GUI tool has dependencies on Qt(V5.4 and up) and CXL - These file are copied from common & CLX folders to the Compressonator.exe folder when the project solution builds "CopyScript" project.
