PVR Viewer
Extension for Visual Studio Code that adds image preview for PVR (.pvr) texture files. All texture decompression is written in JavaScript, so any format will work on any graphics card.
Features
- Large textures are scaled down to fit the window.
- Textures with premultiplied alpha are shown correctly.
- Linear textures not converted to sRGB colorspace for display.
- No zooming or other user control of the viewer.
- No support for viewing cubemaps, mipmaps, arrays, 3D textures.
- Floating point textures have no exposure control for display.
- Packed YUV formats are not supported.
Texture Formats
Initial goal is to support all formats required by OpenGL ES 3.2, listed below:
