pvrtexture::GenerateMIPMaps() fails to generate

[sasmaster]

I am loading a texture data from tga image file.Sizes 512x512 ,RGB 8 bit per channel.The texture is correct both on load and on save without mipmaps generation.However, when I try to do this:

   ```

pvrtexture::CPVRTextureHeader header1(pvrtexture::PVRStandard8PixelTypeRGB.PixelTypeID, height, width); pvrtexture::CPVRTexture texture(header1, imageData); bool result = pvrtexture::GenerateMIPMaps(texture, pvrtexture::EResizeMode::eResizeCubic, PVRTEX_ALLMIPLEVELS);

          It returns false.
UPDATE:
Sorry,it DOES work with RGBA textures.So the input texture must be RGBA always?
