Looking at this thread, this appears to be a know issue:

> [@RGB or RGBA rendering of single 2D image in 3D not working](https://discourse.slicer.org/t/rgb-or-rgba-rendering-of-single-2d-image-in-3d-not-working/16649/2):

> 3-component RGB images appear correctly in slice views and the slices can be displayed in 3D view, too. 4-component RGBA images are required for color volume rendering but RGBA volumes, but slice views of such volumes cannot be displayed in 3D view - see [this issue](https://github.com/Slicer/Slicer/issues/4939). If you want this to be fixed then [add a vote for it](https://discourse.slicer.org/t/about-the-feature-requests-category/30). If an issue gets many quotes (or needed for a funded project) then we can allocate developers to fix it. If you need it sooner and you are comfortable with C++ and the VTK library…

In that case, is there a way to convert RGBA image into RGB in Slicer?
