An image and texture viewer for tga, png, apng, exr, dds, pvr, ktx, ktx2, astc, pkm, qoi, gif, hdr, jpg, tif, ico, webp, and bmp files. Uses Dear ImGui, OpenGL, and Tacent. Useful for game devs as it displays information like the presence of an alpha channel and querying specific pixels for their colour.
The software seems to support opening mipmaps for KTX & DDS files, showing the file have multiple frames. However OpenEXR can also support mipmaps.

Would it be possible to support opening mipmapped OpenEXR files in the same way as DDS & KTX?
