Voxenta is a basic image processing UI tool made with ImGui, OpenGL and OpenCV with simple interface and effects descriptions. It was created to make things easier with image processing to use ready-made UI environment and focus only on the effects creation in C++ using OpenCV (default) or other libraries. Application was tested on Linux but it should also work after building it for Microsoft Windows environment.

- Prepare the effect class (need to inherit from effect class, study example effects).
- Put it into source/voxenta_effects/src/effects directory.
- Use Effects -> Reload effects button or CTRL+R shortcut to reload. It works in runtime.
- If your effect was correctly prepared and has no errors, it should appear in dropdown options list.
You can load an image file that is supported by OpenCV with File -> Load (CTRL+O). It will be shown in left image window. Then choose the effect from dropdown and set it's properties. It will be automatically applied to the image and shown in the right window. Then you can save it using File->Save (CTRL+S) option from menu. Use image file extension supported by OpenCV.
You can apply more than one effect. Just use Effects -> Apply (CTRL+A) shortcut to create a new chain element. Now processed image will appear on left window. You can undo this operation with Effect -> Undo (CTRL+Z). The saved image is one that is visible on right screen so remember not to apply the last effect.
Now you can modify your effect file and use Effects -> Reload effects (CTRL+R) to reload changes in runtime. It grants fast and usefull tool to experiment with effects with no need to rebuild the project.
